1 - Abstract Considering the importance of tax function in the country's economy, it is necessary to reform the tax system and eliminate its deficiencies. Public acceptance is actually the level of society's trust in the country's tax structure and the assurance that tax justice is observed on the one hand and that the collected tax is spent on the development of the country on the other hand. On the other hand, tax evasion has always been one of the major concerns of governments in order to get closer to tax justice while providing maximum tax revenue, so the purpose of this research is to provide a proposed model for reforming Iran's tax system with two approaches of increasing public acceptance and reducing tax evasion. . The current research was conducted with a combined approach (combining qualitative and quantitative methods). In the qualitative part, the conceptual model of the research was designed by asking the opinions of 32 tax experts and through an open questionnaire. In the quantitative stage, through a statistical sample consisting of 112 informed people, the model designed with the structural equation modeling (PLS) approach was tested. The results show that the tax system is the foundation for the promotion of transparency due to its supervision and requirements. Transparency also has a positive and significant effect on reducing tax evasion in this area. Also, reducing tax evasion will increase public trust in this system.

Therefore, some researchers sought to coordinate and integrate production, maintenance and repair. The issues of integrating production planning, maintenance and repair and quality control with other parts of production and industrial systems reduce costs and increase the profitability of production organizations. Accordingly, in this research, integration and continuity in simultaneous planning of production areas and support in production organizations have been discussed. These areas include the schedule of production, maintenance and preventive maintenance, and human resources. Therefore, the mathematical optimization model is presented with the aim of manpower planning and increasing the volume of the company's production by considering the limitations of human resources. In this model, personnel skills, equipment usage rate and equipment failure rate in case of uncertainty with fuzzy method are used in the model parameters. The purpose of the proposed model is to minimize the labor force deficit over production efficiency. The results obtained from the implementation in a production organization by comparing the indefinite and meta-innovative solution show the improvement in the company's production with the least reasonable time, provide answers with the least possible error. Sensitivity analysis shows that the rate of equipment failure in the intervals before and after the preventive maintenance process has a great impact on the value of the objective function of the mathematical model.

This paper examines the volatility of cryptocurrencies, with particular attention to their potential long memory properties. Three different long-memory methods (R/S analysis, fractional integration and fractional GARCH extensions) are used to analyze it in the case of the four main cryptocurrencies (BitCoin, Ethereum, LiteCoin and Ripple) over the sample period January 2013– November 2019. Our results are twofold. First, R/S method is prone to detect long memory whereas the findings of ARFIMA and GARCH type models indicate that in the case of two examined cryptocurrencies (BitCoin and Ethereum), long memory exist (there is a positive correlation between its past and future values). Such predictability represents evidence of market inefficiency in their markets: trend trading strategies can be used to generate abnormal profits in these markets. Although our findings show that returns of Litecoin and Ripple don’t have a significant long memory. Manuscript profile -

However, in our society, due to uncertainty and rapid development of new technology, we usually have to forecast future situations using little data in a short span of time. The historical data must be less than what the ARIMA model employs which limits its application. The fuzzy regression is able to forecast model which is suitable for the uncertain condition and with little attainable historical data. But the results of this model cannot be encouraging because the spread is wide in some cases. The researchers do try to combine the advantages of the fuzzy regression and ARIMA models to formulate the FARIMA model and to overcome the limitations of the fuzzy regression and ARIMA model. Therefore, in this study, a synthetic fuzzy auto regressive integrated moving average (FARIMA) is employed to forecast crude oil price. The findings show that the proposed method can get more satisfactory results. Manuscript profile -

Hence, the runoff, suspended sediment and nutrient (Nitrate and Phosphate) yields from main tributaries of the Zarivar Lake were determined and their spatial and temporal variations were also investigated. A number of eight sampling points on the seven lake tributaries were monitored from March 2011 to April 2012 under base flow condition by daily sampling and event bases by hourly sampling intervals. The total yields of runoff, suspended sediment, nitrate and phosphate to the Zarivar lake during the study period were obtained to be 9.7 Mm3, 685.4 t, 25.4 t and 1.15 t, respectively. Almost seven storms were occurred during the same period due to which 1.61 Mm3 runoff, 685.4 t suspended sediments, 4 t nitrate and 211 Kg phosphate were transported. Some 8.1 Mm3 runoff, 718.65 kg suspended sediments, 21.4 t nitrate and 994.35 Kg phosphate were also entered into the Zarivar lake during base flow condition. The results of this study showed that northern parts of the watershed mainly contributed in runoff and nitrate yields. The maximum suspended sediments were also yielded by northern and western parts of the watershed. Whereas, the western parts of the watershed yielded the maximum phosphate to the Zarivar lake. The maximum contribution of runoff, suspended sediments, nitrate and phosphate were respectively happened in spring and winter seasons. About 82 percent of suspended sediments entered to the Zarivar lake during the study period just by one spring event with a duration of some 50 h. It clearly revealed more temporal variability of the suspended sediment and therefore further precaution for better management of soil and water resources of the closed Zarivar lake watershed.

To stablish this system in hospital, the attitude and knowledge, and eventually the practice of hospital staff toward this issue is important. This study was conducted to assess the knowledge, attitude, ad practice of healthcare workers toward health, safety, and environment. Method: The study had a prospective descriptive cross-sectional design. The study population included 435 physicians, nurses, para-clinic and administrative staff working in a teaching hospital affiliated by the Iran University of Medical Sciences. Knowledge, attitude, and practice of included participants were assessed using a standardized 60-item questionnaire. Findings: The knowledge, attitude, and practice of participants differed between different job categories and between different hospital wards. In overall, higher level of education found to be significantly related to the higher attitude toward the health safety and environment (P<0.05). The knowledge and practice did not show any difference between male and female participants. The age of participants did not found to be related to knowledge, attitude, or practice. High levels of knowledge and attitude was not positively correlated with practice. Period while in the validation period these coefficients were 0.77 and 0.73, respectively. Conclusion: The findings of the study emphasize a suboptimum level of knowledge and practice in the field of health safety, and environment among hospital staff. We suggest using continuing education standards, positive and negative reinforcements, and constant evaluation and monitoring as effective tools for increasing the knowledge and practice of hospital staff in health safety and environment.

In fact, economic models can be tested by checking the level of forecasting accuracy. The main purpose of this study is prediction of Iran interbank offered rate and Iran treasury exchange rate as interest rates indicators for facilitating interest rate risk management. Two econometric models including ARFIMA and ARIMA have been used for forecasting. Thus, the ARFIMA model considering long-term memory and the ARIMA model without considering long-term memory have been considered. The evaluation of the prediction accuracy of the two models using the monthly Iran interbank offered rates data and also the monthly Iran treasury exchange rates data shows that both the interbank offered rates data and the Islamic treasury bond rates data, ARIMA model has a better performance compared to ARFIMA model in predicting data.

Always predict the price and volatility has been of the challenges facing traders in oil markets and price forecast is raised as an imperative and functional however, should be noted forecasts that will take place in more accurate and less error than the observed actual results. In order to predict the weekly price of Brent crude oil as an oil indicator given the difficulty of accurately identifying linear and nonlinear models in economic and financial time series from combining Autoregressive Integrated Moving Average models (ARIMA) by the assumption that the time series have a linear pattern and support vector machine (SVM) which has great potential in modeling nonlinear model is used to enhance the accuracy of prediction. Given two paired comparison performance criteria of root mean square error test (RMSE) and the mean absolute magnitude percentage error (MDAPE) which are resulting from the predicted values and actual values for each model, this indicates that in most cases the hybrid model provide smaller errors in predicting the future price of crude oil as compared to the individual applications of autoregressive integrated moving average models and the support vector machine.

The aim of this research is to design an integrated management model for the country's energy sector with an emphasis on environmental policies. Material and Methodology: This article is a qualitative research. The statistical sample of the research (elite) has been selected as a cluster from among the members of the statistical community. In this way, the statistical population was first divided into different clusters (cluster of faculty members, cluster of oil sector managers, experts in the field of oil industry in 1400), then, according to reaching data saturation, a total of 25 experts were interviewed. To analyze the data in the interviews section, three stages of open coding, central coding and selective coding have been used. Data analysis has been done according to the grounded theorizing method after conducting the interview, during three stages of open coding, central coding and selective coding. To do this, Maxqda software was used. Findings: Based on the findings of this research, 18 components were extracted from the 101 primary concepts in the axial coding and finally, in the selective coding stage, 5 main categories were extracted under the headings of social dimension, technical dimension, economic dimension, environmental dimension and legal dimension. political and legal were selected as the dimensions of the integrated management model of the country's energy sector in the final model. Discussion and conclusion: Environmental and international policies can reduce the pollution of the energy sector, including oil, and the legal measures carried out at the international level can control and monitor the environment. Institutional and political factors play a key role in promoting the transition to renewable energy, and improving these factors can lead to decarbonization of the energy sector in the long term. Global financial development has no significant long-term impact on the transition process, which means that the entire financial system needs a fundamental structural change to accelerate the substitution between polluting and clean energies. However, in the short term, the impact appears to be negative and significant, highlighting the inadequacy of financial institutions and financial markets in promoting a sustainable path in the region.

However, little res MoreRealizing a cosecant-squared pattern is a challenging research area due to its widespread use in air-surveillance radar systems wherein the radiation characteristics of the tracking antenna play a significant role in accurate tracking of the targets. However, little research has been performed on realizing a cosecant-squared pattern in leaky-wave antennas (LWAs). In this paper, the authors present a synthesis procedure for realizing a cosecant-squared pattern in LWAs using optimization. To achieve the cosecant-squared pattern, the antenna is divided into sections each with an appropriate length, periodicity, and leakage rate. The length of the sections is determined such that all the sections have the same directivity. Moreover, following the appropriate layout for the beam pointing angle of the sections, the periodicity of the sections is obtained. The objective then is to determine the values of the leakage rate. This objective is achieved using optimization, which in this study is a genetic algorithm. To this end, through defining a proper cost function, the objectives are determined following the proposed optimization procedure. The procedure is described within a substrate integrated waveguide (SIW) LWA. A prototype of the antenna is fabricated and measured. Apart from the good agreement between the simulation and the measurement results, the proposed synthesis procedure can provide a target pattern with low ripples in the shaped region (≤ 2 dB) and a low level of side lobes (≤ -18 dB), making the antenna suitable for air-surveillance radar systems.

The idea presented in this paper is based on the use of a parallel-parallel feedback structure with a cascade interest rate. This structure is quasi-differential and is designed to increase the allowable range of input power and prevent amplifier saturation, a circuit with a variable gain. The simulation results show a maximum gain of 64 dB, a bandwidth of 1.8 GHz, power consumption of 20mw, and a spectral intensity of the noise current referred to as the PA / 9 input. Also, by using variable gain control, the gain of the amplifier transmission impedance can be reduced to 46 dBΩ. The results indicate that the proposed design is very suitable for a 2.5 Gb / s optical telecommunication system. Manuscript profile -

Considering the internal logistics aspects, due to the limitations and resources available in order to reduce costs by increasing the level of capability, the supply systems of materials and components will be achieved along the line. Considering the effect of the completion time of pick operations on the start time of distribution operations and the cost of order preparation tardiness, the present study aimed to investigate a new issue related to the integrated process of order preparation in the warehouse and delivery on time to minimize cost according to the data of a car companys. In this regard, an integer nonlinear programming model is proposed to minimize the costs caused by tardiness. In order to validate the model, the small problem is solved in exact way. To solve the model, since the problem is NP-Hard, the method of whale optimization algorithm was used and to improve the optimal routing solutions, the problem was investigated by designing an adaptive whale algorithm considering the cost and time of visiting workstations as a fitting function. Also, to assess the proposed adaptive whale algorithm, the results were compared with two meta-heuristic algorithms of particle swarm optimization and gray wolf. The results show that the proposed adaptive wall algorithm performs better than other methods, which improves and reduces costs. Manuscript profile -

The experiment was performed in greenhouse with five treatments (vermicompost tea, azotobacter-enriched vermicompost tea, takumi pesticide, Azotobacter and control) with four replications in a completely randomized design. Three days after spraying, the numbers of larval tunnels on leaf and thirty days later, the numbers of adult moths of T. absoluta were counted. The results revealed that tomatoes treated with Azotobacter enriched vermicompost tea and Takumi had the lowest number of adult moths (9.35 and 13.75 per plant respectively). As well as, the azotobacter treatment was able to reduce the adults moth by up to 50% compared to the control. The results of the number of larval tunnels showed that the mean number of larval tunnels/plant for Azotobacter enriched vermicompost tea was 19.50, which compared to other treatments, had the best effect in reducing the damage of tomato leaf miner. Vermicompost tea and Azotobacter as biological fertilizers, besides being able to increase the yield of tomatoes, have an effective role in reducing the population and damage of the tomato leafminer pest, and they can be used in sustainable agriculture as an alternative with pesticides.

Undoubtedly, spatial management requires a spatial decision support system that is dynamic and interactive. Spatial Data Infrastructure (SDI) is an effective approach in spatial information management which has made great progress in recent years. This research, while recognition the influential institutions in the integrated management of the capital's peri-urban areas, evaluates the factors and criteria of readiness for the establishment of spatial data infrastructure. Data collection was done through interviews and questionnaires, used the SDI readiness index method. 25 selected public and government institutions were evaluated in 16 evaluation criteria and institutional readiness index and readiness index was calculated. In general, the two factors of Technology and Information, in comparison with the three factors of Organization, Human Resources and Financial, face less challenges and problems in establishing a spatial data infrastructure, but overall, no significant difference was observed between the factors. In a more detailed analysis, the criterion of private capital and return on investment are not very good compared to other criteria. Also, in this research, four institutions were found to be more ready and three institutions were less prepared than others to implement SDI. The readiness index in the peri-urban influential institutions was calculated as 0.47, which is slightly below the average. At the end, in order to remove the obstacles, suggestions were presented focused on: strengthening the private sector, increasing public awareness and managers, reforming the attitude of governance and data power and expanding the culture of information dissemination, promoting inter-institutional cooperation, focusing on data infrastructure projects instead of creating inefficient systems.

Accordingly, this study seeks to identify the determinants of tourism competitiveness in Iran using Dwyer’s integrated model. After selecting the indicators and categorizing them into six groups, a questionnaire was developed and 129 questionnaires were completed through a web survey. The study population included all employees of the public and private tourism sector as well as professors and students of tourism field were selected. In addition to identifying the determinants of competitiveness of urban tourism, competitiveness of urban tourism was analyzed using OECD indicators. In order to test the reliability of the questionnaire, Cronbach's alpha was used. The results revealed that among the six key determinants of competitiveness of urban tourism, only endowed resources (with a total average of 4.17) and situational condition (with a total average 3.55) had relatively favorable conditions. The analysis of the relationship between tourism and six determinants of competitiveness revealed that endowed and created resources have had greater, direct and indirect effect on the competitiveness of urban tourism. Accordingly, protection and enhancement of the environment, the diversification and development of recreational activities, festivals and exhibitions, quantitative and qualitative improvement of tourism guides and information as well as marketing and advertising are suggested as the main recommendations of the study.

For this, the inflation rate of Iran in period 1937-2016 and on the base of fractionally integrated (FI) approach was modeled and in the later phase inflation memory parameter has been estimated by using classic methods (the Geweke and Porter-Hudak semi parametric method nonlinear least squares, exact maximum likelihood, and a minimum distance estimator) and Bayesian methods. The results of the estimation in both methods show that the inflation rate in Iran is stable. Stability of inflation rates has important implications for policy-making, especially monetary policy, so that due to the impact of economic shocks on inflation, its effects will be last for a long time. Therefore, it is necessary to policy makers identify the major sources of distorting inflation, including dependence on oil resources, no attention to the role and function of the reserve fund, the government budget deficit, central bank dependence and the existence of structural problems and consider appropriate approaches in this field.

One of the most well-known areas that has received a lot of attention is electricity forecasting. The features of the electricity which makes it distinguished from other commodities are the impossibility of storing it and the existence of seasonality and nonlinear and ambiguity pattern in electricity data set. These features of the electricity makes it more difficult to forecast using traditional methods. Therefore, in this paper, a parallel optimal hybrid model using seasonal linear and nonlinear methods is proposed to forecast the electricity load forecasting. The main idea of this model is the use of the advantages of individual models in the modeling of complex systems in a structure, simultaneously. Experimental results indicate that in this method due to the use of a direct weighting method, the computational cost of modeling it is significantly lower than other parallel hybrid methods.

These applications are used to cover an airspace to search for targets and estimate their height. In this article, a method is proposed for the synthesis of cosecant squared pattern using leaky wave antenna. The principal mechanism in the leaky wave antennae is wave attenuation due to power leakage while the wave propagates through the structure. Thus, by controlling the leakage and phase constants along the length of the structure, one can synthesize the desired radiation patterns. We have used the genetic algorithm to optimize the leakage constant and obtain the desired cosecant squared pattern In the range of 10 to 30 degrees. Conformity in simulation results and measured results indicates accuracy in the design process. The proposed method obtains the desired pattern with a ripple of less than 2 dB in the designated area and side lobe level less than -18 dB, which makes the antenna suitable for radar applications.

The proposed IRM is composed of 2-element microstrip rectangular patch antenna, three compact branch-line hybrid coupler (BLC), two balanced mixers, a Wilkinson power divider, and a lumped element hybrid coupler. The proposed IRM translates radio frequency (RF) (2.4 or 2.5 GHz) to two intermediate frequency (IF) and provides isolation to two possible IF. The IF and local oscillator (LO) power are chosen 50 MHz and 5 dBm, respectively. The proposed IRM is able to achieve image suppression with an isolation of approximately 20 dB. The conversion loss is lower 10 dB. The VSWR at two output ports are 1 and the VSWR at the RF port is greater than 1.8.The balanced mixer is composed of a compact BLC, two schottky diodes, two short-end stubs, and an open-end stub. By replacing the quartet-wavelength conventional transmission lines with equivalent t-type transmission line, the compact BLC is designed, which they can suppress upper order harmonics and spurious passbands of the antenna. Miniaturize, low cost, simple circuitry, and high performance, are the main advantages to simulation this AIA with IRM. The AIA with IRM is simulated by ADS software. Manuscript profile -

In this paper a novel waveguide type directional coupler based on substrate integrated waveguide consisting a double layer dielectric substrate is proposed. The design process is carried out using coupling theory and Chebyshev method. The proposed structure is fully based on SIW structure except at the input-output ports which are microstrip lines. The SIW bends are optimized for the lowest insertion loss using HFSS software. The center frequency of designed 20dB coupler is at 10GHz with 6GHz bandwidth. Based on the simulations the coupling remains almost constant over the coupler bandwidth with less than 2 dB variations. Larger bandwidth can be achieved by increasing the number of apertures. Also if we used a second set of apertures opposite side wall, the coupling would be increased by 6 dB. Manuscript profile -

MoreIn the third millennium AD, thinkers and urbanists are seeking tools to comprehend the complexities of urban spaces. Data and information have emerged as the language for understanding the spatial behavior of cities and the primary tool for analyzing their complexities. Therefore, this research aims to highlight the significance of statistical sources, including urban statistics, for analyzing urban issues. The research employs a descriptive-analytical and inferential methodology. Data collection involved gathering documents, specifically statistical texts published by municipalities in the previous year. While there was no specific statistical population or geographic area for this study, the focus was on the statistical yearbooks of municipalities, particularly those in the central cities of provinces. Data analysis utilized content analysis and simple quantitative statistical methods. The findings reveal disparities in content and format in urban statistics, as well as the absence of a comprehensive and integrated statistical system. Further investigation uncovered inconsistencies in the preparation and compilation of urban statistics regarding time, location, and adherence to statistical standards. Additionally, many statistical data and information available in municipal statistics, such as urban competitiveness indicators and metrics for measuring progress, development, and urban planning, remain underutilized. To address these issues and achieve integrated and comprehensive urban statistics, it is recommended that cities update and publish their statistics annually, following a standardized framework consisting of 22 chapters.

Despite the fact that more than 100 years of Tehran's urban modern-city management system, but due to the overwhelming focus of the government in the management of cities, municipalities and councils, they still do not have the necessary independence for their decision making and urban policy. Therefore, attention and explanation of this issue is one of the most important issues which is necessary considering the development of physical, spatial and demographic development, as well as the complexity and complexity of the problems and challenges of Tehran. This paper is aimed at strategic planning of integrated urban management in Tehran metropolitan area based on the strategic planning model of Meta-SWOT. The present study is descriptive-analytic, and in terms of target targeting. The data collection method has been a library and survey. The results of this study indicated that among the resources and internal capabilities of the modification of urban management laws, the integration of all actors in the field of urban management and general management in the city had the highest score. Also, the results of external environmental factors that indicate that the unidentified components of the integrated attitude in urban management, the lack of separation of political leadership from specialized management and the lack or weakness of the mechanisms for strengthening organizational communication indicates the impact of environmental factors. According to studies, the northern regions have the least and the southern regions of Tehran metropolis have the highest level of inconsistency. Therefore, in proportion to the growth of urbanization in Tehran, there is a lack of formation of integrated urban management. As a result, there is no reasonable coordination between the construction of spaces and the body of the city and the natural and physical environment with the social, economic and cultural situation.

The purpose of this study is to investigate the relationship between integrated financial reporting with earnings forecasting bias and stock price awareness. The statistical population of this research is all companies listed on the Tehran Stock Exchange and 167 companies in the period 1391 to 1399 have been selected by systematic elimination method. Also, to test the research hypotheses, a multivariate regression model based on composite data was used. The results of the first hypothesis indicate that there is a direct and significant relationship between integrated financial reporting and behavioral financial bias in stock price forecasting. The results of testing the second hypothesis showed that there is a direct and significant relationship between integrated financial reporting and accuracy of profit forecasting. Integrated financial reporting with disclosure of financial and non-financial information from the financial reporting process and corporate activity makes investors and analysts more accurate forecasts. The results of testing the third hypothesis showed that there is a direct and significant relationship between integrated financial reporting and stock price awareness. He said that by combining financial and non-financial information, the process of creating value for the company in the form of financial reporting makes the information content of stock prices informative and investors in stocks make optimal decisions according to rational investment theory.

This has made business sustainability and social responsibility more important. The main purpose of this study is to formulate and explain the model of factors affecting integrated reporting by heuristic mixed method. For this purpose, first the qualitative part, using the data method of the foundation and interviewing 19 experts by snowball sampling method, integrated reporting categories and stimuli including causal conditions, background conditions, intervening conditions, strategies and consequences were formulated and modeled. The final was presented. In the quantitative part, research hypotheses were developed and to test them, a questionnaire was designed and information was collected by 368 people who did not participate in the qualitative part. Hypotheses were collected and tested by structural equation method using smart PLS software. The results of the quantitative stage showed that the causal category (legal requirements and conditions and political and economic relations) affects the central category (integrated reporting), the central category (integrated reporting) affects strategies, the intervening condition (instructions and characteristics of the company's management) It affects the strategies, the context conditions (accountability and evaluation system and company facilities) affect the strategies and the leaders (creating a responsible institution and setting the standard and training) affect the consequences.

Therefore, bank managers are keen to know how much the total bank deposits will be at a given time in the future. Predicting the amount of deposits, changes and fluctuations of these deposits can help banks in planning and decision making. In this research, using statistical techniques and approach of artificial neural network models, we have tried to introduce a model with the highest estimation power and the least amount of error to predict the amount of deposits or the same sources of finance by their different types for the desired bank. To test the hypotheses, one private bank information was used during the period of 1387-1396. In this research, we compared the predictive power of ARIMA and artificial neural network method. To assess the accuracy of forecasting the bank's resources, the ARIMA method used Coopiff and Christopherson tests. The results of the research on the amount of bank deposits monthly showed that the neural network method provides better estimates than the ARIMA method. Manuscript profile -

According to the efficient market hypothesis, prices follow a randomized step process, so returns on assets can not be predicted based on past price changes. Long-term memory is a weak point of the business-market hypothesis. Long-term processes have important implications for asset yields and play a crucial role in time series analysis. This study examines the existence of long-term memory in the price index of crypto currencies equals $ 1 and lower for the period from September 1, 2015 to September 1, 2018. To estimate the parameter d, the OLS method is used in the EVIEWS software package. The ARFIMA model is used to test hypotheses. The results indicate that long-term memory is in the currencies of DIGIBYTE, Dodge Coin, EMER Coin, BITSHARES, MAIDSAFE COIN, XEM, Redd Coin, NXT, Verge and Ripple, and on the other hand, three currencies of Byte Coin, SIA Coin, STELLAR lacks long-term memory, and therefore these currencies are among the most efficient market products.

The proposed model integrates various parameters such as total cost, lead time, service level, and residual capacity, addressing the complex interdependencies among an omnichannel environment of retailers. To enhance the model's reliability, a hybrid meta-heuristic algorithm is employed, combining the strengths of MOEA/D-DE (Multi-Objective Evolutionary Algorithm with Differential Evolution), IBEA (Indicator-Based Evolutionary Algorithm), and NSGA-II (Non-dominated Sorting Genetic Algorithm II). The collaborative optimization approach ensures adaptability and efficiency in addressing diverse and intricate optimization challenges inherent in omnichannel networks. The numerical data from a case study on the supply of sanitary masks in Tabriz, Iran, during August 2021 is utilized to validate the model within the specific omnichannel context. The study includes a thorough sensitivity analysis, demonstrating the model's robustness against disturbances in the omnichannel network. The consistent performance of the odel across various disruption scenarios underscores its reliability and efficacy in ensuring the stability of supply chain operations within omni-channel frameworks. This observed resilience significantly enhances the overall robustness of the supply chain, especially when confronted with disruptive events. The model's ability to maintain stability under diverse conditions contributes to fortifying the supply chain against potential disruptions, thereby augmenting its adaptive capabilities in dynamic environments..Managerial and practical implications are discussed, emphasizing the significance of the proposed reliable omnichannel approach in leagile demand-driven systems.
