If sequence of jobs is neither deterministic nor controllable, then sequencing and schedulingissue will knot to the decision making under conflict and uncertainty that has been addressed in thecontext of sequencing and scheduling models for the first time in here. Models created under theseconditions are named wariness models. In this paper, a general approach is presented for the solutionof such problems and moreover, a pessimistic-based method for solving the problems with the fixedresources arrangement is introduced. Anti-Akers-x algorithm has been propounded to determineidentical job sequences in an n × m environment to maximize Fmax. The wariness models complexity ischecked and then an application example is propounded from the wariness models and it was solvedusing Anti-Akers-x algorithm and the solution obtained was checked by the general method. Finally,Anti-Akers-x algorithm’s validation and verification are tested. It is concluded that: the relatedproblems must be solved by game theory and the presented schedule is able to solve this strongly NPhardproblems correctly and in reasonable time duration.

It is important how one should allocate such costs among all competing DMUs. Data envelopment analysis (DEA), which is a useful tool to evaluate the relative efficiency of DMUs, has been successfully used in allocating fixed costs among DMUs. Two main approaches have been proposed to allocate fixed costs that are based on maintaining or improving the relative efficiency of DMUs. In fixed costs allocation, one however needs to take into account both competitive and cooperative aspects among all DMUs. Therefore, it seems more reasonable to apply a peer-evaluation method in evaluating the efficiency of DMUs. To this end, we use cross-efficiency evaluation in DEA to allocate fixed costs between DMUs. Using cross-efficiency method and some concepts of game theory, we propose a new fixed costs allocation approach to share costs between DMUs such that the vector of cross-efficiency scores of DMUs after allocation is Pareto. We use a real application to more illustrate the proposed method and compare it with some of the existing methods. Manuscript profile -

Suitable resource allocation, more specifically that includes suitable base station selection and bandwidth allocation can play an effective role in interference mitigation and users’ quality of service requirement satisfaction. In this paper, a game theoretic approach is proposed to solve the BS selection problem in two-tier wireless femtocell networks. We formulate the competitive behavior of users as evolutionary game theory. We calculate the probability of a user choosing a BS, compute the cell load of each BS, and analyze the demand rejection probability of the user associated with the BS. The proposed approach maximizes network throughput as well as meeting the QoS requirements of the users. Finally, we propose a decentralized learning algorithm based on EXP3 algorithm to achieve the evolutionary equilibrium as the solution of the game. Simulation results show that the proposed approach achieves a desirable performance and guarantees users’ QoS requirements. Manuscript profile -

Solving of these conflicts and getting agreements over transboundary waters has always faced many challenges that make it difficult to reach a consensus solution. Afghanistan, Iran and Turkmenistan Conflicts over Harirud river waters is among the transboundary river waters conflicts that have escalated in recent years. Material and Methodology: Assuming that the parties are willing to hold negotiation in order to reach an agreement over Harirud river waters, in this paper the probable options of each party were identified with respect to the prevailing international principles and theories on how to divide common border waters. After defining five options for negotiation, in order to identify social optimal situation, six common social choice rules including Condorcet Choice, Borda Scoring, Plurality Rule, Median Voting Rule, Majoritarian Compromise and Condorcet’s Practical Method were used. Finally, by using the aforementioned social choice rules, the most probable result was determined.Findings and Conclusions: The results showed that water trading market option, based on all rules of social choice, exception of plurality rule, was chosen as optimal situation. Therefore, based on the social choice rules, it can be said that the water trading market option is the most likely solution which there is a possibility of an agreement between the three countries over Harirud river waters conflicts.

In other words, parts of these two theories show signs of equivalency. However, the mathematical proof of this equivalency must be done through separate studies. In addition, there is speculation that parts of Investment theory could be reduced to Game theory. The use of Chaos theory as a link between the various sciences involved in investment (i.e., economics, game theory, mathematics, social psychology, and behavioral economics) can make investing science an interdisciplinary and transdisciplinary science and introduce a cross-discipline and use the capabilities of different sciences to explain the complexities of investment science and through the analysis of chaos theory.

One of financial market characteristics is conflict of interest among market players which cause to the main trend of market be derived by market player’s interactions and each player’s strategy be a function of the other’s play. The second one is uncertainty. Both features are analyzed in Game Theory in order to optimize decision making process.In this paper, united players with negative, less than one, more than one and zero beta, established a coalition against the Market and tried to select securities that enable them to outperform it. The Market used its mean plus and mines three standard deviation as its strategies. Then player’s payoff in each strategy is determined based on how its return is better than Market and Risk free return and also how its Sharp ratio is better than the Market one. After running the game and finding the Shapely value, the optimized weights of each player and each security was calculated. The findings shows that united players won seventy five percent of twelve annual periods ending March 2018 regarding Treynor and Sharp Ratios. Also their performance was meaningfully better than the Market in the whole twelve year period. Manuscript profile -

Or for whatever reason (perhaps morally) they refrain from doing so. The purpose of examining this conflict and cooperation between managers and shareholders of listed companies using game theory is to find a balance point in which the manager and the shareholder are satisfied as the main elements of the game in order to maximize their interests. Accordingly, this study seeks to find a strategy to maximize the equilibrium benefits of managers and shareholders by applying strategic features of accounting information and accounting conservatism. The method of data collection is the method of document mining during the period (1391-1391) and the method of data analysis is inferential and the software used to prepare the data and estimate the models is SPSS. The test results of the research hypotheses show that the combination of high conservatism strategies - high reporting quality and low conservatism - low reporting quality - are the equilibrium points (Nash equilibrium) in the game between the manager and the shareholder. The results show that game theory plays an important role in the relationship between managers and stakeholders; and finding the equilibrium points of the game can play an effective role in the decisions of the game parties (managers and shareholders). In this way, it informs the parties of the game of the strategy that has been most desirable and beneficial for them. Manuscript profile -

Therefore, it is very important to use a method that is understandable and able to communicate between managers and stakeholders in the decision-making process. The purpose of this study is to use the game theory in environmental areas such as biodiversity conservation, environmental pollution and land allocation. Material and Methodology: The method of data collection in this study includes library and documentary review and content analysis of studies conducted in this field. In the area of biodiversity conservation, the role of game theory in managing protected areas, as well as the application of this method in the behavioral ecology, has been described. Moreover, in environmental pollution and land allocation, the application of game theory in waste management and land use planning has been investigated respectively. Results: Game theory is used as a method to solve environmental management problems in developed and developing countries. Whereas game theory can predict stakeholder behavior in the decision-making process, this will solve conflicts between stakeholders. By applying this method, many environmental problems that are caused by the common use of stakeholders from the environment will be solved. Discussion and Conclusion: This article examines the various applications of game theory in three major areas of the environment, namely biodiversity protection, environmental pollution, and land use planning. It is clear that by using this technique, many of the problems facing the country's environmental management can be modeled and solved. Keywords: Manuscript profile -

But what is not taken into account in this type of calculation is the price of model inputs. In calculating technical efficiency, the amount of output to the input is maximized, and the model can be used to identify efficient decision-making units, while it is possible to determine the decision-making unit that is at the efficiency limit and a reference for other units. Decision-making systems are efficient at a high cost, and it is possible to find decision-making units that are on the verge of efficiency at a lower production cost. Cost Efficiency seeks to find points that are on the edge of efficiency at the lowest cost. Given the importance of cost efficiency and the lack of attention to this concept in network and multi-stage structures, this study investigates cost efficiency in a purely two-stage process. In the present study, using the concept of game theory and data envelopment analysis in a centralized and decentralized state, we evaluate the performance of purely two-stage processes. In order to investigate the validity and efficiency of the models and their applicability, a case study has been used in the Iranian electricity industry and some management results are discussed.

The paper proposes a multilevel green transportation model under multi-stakeholder’s condition, that game theory could be used to selects the best interactive mode by presenting different scenarios so that all stakeholders in a game achieve their maximum benefits.In this paper, a comprehensive multi-level supply chain model consisting of several simultaneous stakeholders has been considered. An optimal model was developed to achieve the lowest cost at different levels of the chain. The optimal model includes the lowest costs of purchase and production, maintenance, shortage, and warehousing. The model also includes various components of products transportation and distribution for all members of the chain. The produced Co2 at different stages of production and transportation for both involved parties was accounted in the model to minimize the environmental impacts. Furthermore, a competition in the context of a game to select the optimal situation between the stakeholders of the supply chain has been considered make the best decision in terms of a participatory game by considering different scenarios. In this paper, Excel and Gams software were used to model and solve the numerical example. The results confirmed the superiority of the optimal values of the game theory model. Manuscript profile -

Therefore, to ensure the realization of these goals, measuring the sustainability efficiency of the supply chain is considered inevitable. The problem of assessing the performance of supply chain sustainability, on the one hand, is affected by the inherent conflicts of interest among sustainability goals, which increase the complexity of the problem, and on the other hand, it should be configured in a way that can simultaneously provide sufficient knowledge of the efficiency of overall supply chain sustainability and sustainability goals. In this study, a combined mathematical model of data envelopment analysis and game theory is presented to evaluate the sustainability efficiency of the supply chain and the efficiency of sustainability goals by considering the trade-offs among sustainability goals. The trade-offs among sustainability goals are formulated using the Nash bargaining game in such a way that the ability to provide simultaneous results is related to the overall efficiency of supply chain sustainability and the efficiency of each sustainability goal. The proposed model was evaluated under a case study for appraising the efficiency of supply chain sustainability of an Iranian pharmaceutical company. The results of the model implementation indicate that the proposed model is firstly capable of simultaneously providing efficiency values of supply chain sustainability and each sustainability goal, and secondly, it provides the necessary and sufficient knowledge in comparison of these values for efficient and inefficient products.

In this article, in order to deal with this issue, a three-level supply chain under random demand is proposed using two decentralized and coordinated models, in which the profit increase of each actor in the chain (supplier-manufacturer-retailer) considered. In the decentralized model under the scenario-based stochastic demand, the retailer and the manufacturer separately decide on the order quantity and investment by considering the scenario-based stochastic CSR-sensitive demand. A wholesale price contract with two adjustable levels is proposed to persuade three levels to enter into a coordination scheme. According to the comparisons made between the results of the algorithms, it was found that the coordinated model performed better than the other algorithm in reducing chain costs and increasing profits. In particular, it can be acknowledged that the coordinated model performed better than the decentralized model by about 144.39% and was able to increase the profit of the chain. Manuscript profile -

In MoreSVM is one of the popular classification algorithms based on statistics learning, which is presented for two-class problems. In real environments, the problem is usually multi-class. Thus, multi-class separation methods are very important compared to binary classes. In this work, to decrease the complexity of the model and the resulting loss of accuracy, fuzzy game theory is derived, which will be able to map the non-linear to a linear problem. Fuzzy game theory is obtained from the probability of data in each class by using two players (in our problem, each player is equivalent to a class label). Here, the decision matrix is yielded by the fuzzy logic, and then the equations are solved by the linear programming. Obtained results from the computer simulation validate the SVM model by fuzzy game theory. Manuscript profile -

Politics is inherently complex, reflecting the complexity of human behavior both as an individual and in the social dimension. This complexity seems much more real at the level of international relations. Artificial intelligence is an influential and pervasive field that scope is not only related to technical and engineering issues, but also includes the fields of humanities, especially international peace and security. Using game theory as part of artificial intelligence in the field of political science and international relations is concentrated in common areas such as equitable distribution, political economy, public choice, war bargaining, positive policy theory, and public choice theory. In each of these areas, researchers have developed game theory models in which player models are often represented in the form of voters, governments, special interest groups, and politicians. Therefore, in this research the role of game theory in international relations will be investigated. Manuscript profile -

Suppose that players are selfish and the score for each criterion for a player is an interval. Each player makes any possible effort to bring about his or her ideal condition. In this paper a new scheme to calculate the minimal cost - benefit ratio for interval data is offered. A player who has minimal cost - benefit ratio is the successful player in obtaining favorite cost and benefits. In this scheme also new models have been proposed to avoid zero weight occurrence.

As a result, the decision-makers must operate in a dynamically complicated environment where appropriate and rapid reaction in a cooperative way is the fundamental key to effectively completing the task. We express a theory of decision modeling and axiomatizing a decision-making process. The payoffs and probabilities are represented with simplified neutrosophic sets. We therefore, provide the theory of choice with the implementation of simplified neutrosophic sets. By exploiting the idea of pure strategy, we introduce two steps: in the first step, for each attractive point, some particular event is selected that can bring about a relatively neutrosophic upper payoff with a relatively neutrosophic upper probability or a relatively neutrosophic lower payoff with a relatively neutrosophic upper probability. A decision-maker selects the most favored attractive point in the second stage, based on the focus on all attractive points. Neutrosophic focus theory has been introduced to improve overall performance with more flexibility in complex decision-making. The approach suggested in this work has been implemented in a real-life example to determine its effectiveness. The proposed method is shown to be the most useful for ranking scenarios and addressing dynamic programming problems in decision-making. Manuscript profile -

In the first stage, the police decide whether to fine or not, and in the second stage, the driver decides whether to pay a bribe or not. The driver compares the amount of the fine and the cost of the bribe. It can be concluded that the more lawful the police, the lower the bribe payment. Punishment of bribe recipients and payers can also prevent bribery and help eradicate possible corruption in this important organ of the country. Manuscript profile -

In this regard, the present study examined the effect of social capital on individual decisions within the framework of teamwork. In order to achieve this goal, we came to the experimental environment and performed an examination of the effects by performing sequential and simultaneous games that were complete, static and dynamic, and perfect and imperfect. 182 students were selected from the population of students from universities of Yazd, and 2184 observations were collected. The results of the study showed that the increase in social capital of a team's players leads to increased team production, team revenue and team profits. The results also showed that people with high level of social capital are not affected by rewards, while reward changes lead to a change in the behavior of individuals with a moderate or lower social capital level.

In this paper a pricing mechanism based on Game theory provided. The pricing mechanism has been developed based on cooperation among producing countries, consumers and gas transmitters that in the case of gas-exporting countries' commitment to it, the interests of these countries will be supplied. So, taking into account the realities of the market and according to the conditions of transmitter country, different scenarios have been compiled and according to it, the modeling is accomplished. The results of the different models in determining price, quantity and optimum tariff for two cooperative and non-cooperative games is that the interest of member countries in cooperative game is far greater than non-cooperative game.

The failure of a credible international agreement in determining the magnitude of the exploitation has led Qatar to become more promising by investing more in its oil and gas industries than Iran; this imbalance has caused a rash and pernicious competition. Following this incident, the main purpose of the paper is to examine the type of communication (cooperative or non-cooperative) through the game theory to achieve an optimal economic strategy for Iran. Results based on non-cooperative game design, solving methods through methods of elimination of dominated strategies (dominate strategies equilibrium), and Nash equilibrium showed that choosing the non-cooperative strategy is optimized for both countries and non-cooperation has more economic benefits for Iran.

In this study, the researchers have tried to examine this program by Game Theory approach. To achieve the goal, firstly, a static game with complete information is planned by three players involving automaker, transportation and fuel staff and old cars owners. Then, by removing the automaker, the game will be continued by two players through specific strategies for each player. Then, by using existing data of the year 2012, the game is re-written by two players. At the balance of three players, old car owners and automakers tend to retire their old vehicle, but the amount of the facilities and cash payments for this program are low. By removing automaker, the balance happens where the car owners tend to retire their old cars and to implement the project, whereas the credits provided by the government is low. Due to the quick increase of car prices, the authorities must pay attention to develop more facilities for the complete success of the program. Manuscript profile -

This paper considers the uncertai­nties of renewable energy resources, load demand, and the charge / discharge schedule of electric vehicles. In order to increase planning flexibility, the operator will be able to change the flow through the distribution feeder reconfiguration. Also in the proposed model, customers will be able to reduce their costs by participating in a demand response program. In the first level of the proposed model, the bidding strategy of microgrids is determined. In the second level, the market clearing price is determined by the independent system operator and according to the submitted bids. Finally, in the third stage, the problem of final microgrid programming is solved by a participatory game theory method. The proposed model is solved by the CPLEX solver in GAMS software and the results show that the dynamic topology improves the planning flexibility and thus reduces the total operating cost by about 10%. The results also show that the coordination of electric vehicles with scheduling, the presence of storage systems and the implementation of the demand response program leads to a significant reduction in the level of market-clearing price and thus reduce operating costs.

The theoretical literature distinguishes between the behaviors of companies in adopting competitive pricing strategies. It is common to study models where all firms are price-makers or price-takers, but the simultaneous application of price-making and price-taking strategies by firms producing a similar product using game theory has not received much attention. Therefore, the purpose of this article is to use game theory with equilibrium concepts forward-looking equilibrium reasoning, and backward-looking individual learning simulation tools to investigate the behavior of companies. The results of the recent study showed that the Cournot-Nash model is a stable model for the real evaluation of pricing strategies in a dynamic oligopoly market. However, with a larger number of firms, a unilateral deviation from Cournot's behavior becomes profitable. In this paper, we have formally proved that the only possible stable market is the Cornot market, where every firm can be a price taker. Conversely, a market in which all firms accept only prices is never stable, and therefore Walrasian equilibrium is not applicable according to the findings. When there are no stable markets, the market does not evolve toward a fixed composition, but the number of price takers typically decreases. In such a situation, the market composition follows a cyclical pattern that is related to the stability or volatility of crude expectations. Manuscript profile -

Agility means the reduction in the workforce by management, which can be considered as a cost leadership strategy. Human resource changes in the company, lower staff costs and personnel salary are the results of agility which in times of crisis is a competitive advantage for the company. According to the game theory, adopting a strategy of cost leadership by managers reduces the risk of bankruptcy. The purpose of this study is to investigate the effect of agility on the probability of bankruptcy. The population of this research is all companies listed on Tehran Stock Exchange from 2011 to 2016, and the sample size based on the systematic elimination method is 175 companies. The multiple regression analysis is used to test the research hypothesis. The results of the study show that managers, by adopting cost leadership strategies and agility policies, significantly reduce the likelihood of bankruptcy. Manuscript profile -

The research population includes managers and experts from 30 top private companies active in the field of oil and gas projects. The research methodology is based on Kumar's classification, which is applied, interpretive, exploratory, and includes both quantitative and qualitative aspects. This study underscores the importance of efficient knowledge sharing as a means to foster collaboration among investors in the portfolios of the National Iranian Oil Company to compete with foreign competitors during sanctions.Upon reviewing the results of four scenarios derived from the game, it is observed that the rewards perceived by companies from knowledge sharing depend on the behavior resulting from knowledge sharing by other companies. The more capable an organization is in the influential factors of knowledge transfer and higher innovation, the greater the returns companies will obtain through cooperation. Sensitivity analysis regarding the costs of project cooperation, which arises due to the difficulty of implementing joint projects, shows that as costs increase, companies shift from a cooperation strategy towards a retaliation strategy and then towards a non-cooperation strategy. These strategies are determined based on aligning the results of the profit equation designed with three interrelated cooperative games: the prisoner's dilemma, the hawk-dove game, and assurance game.

Managers, considering the quality of internal controls, engage in both deceptive and informative earnings management strategies. Shareholders then respond with strategies involving high or low capital costs and opt for either high or low-quality audit services. The findings of the research outline the theoretical conditions necessary for establishing balance in strategies such as deceptive earnings management with high capital costs and deceptive earnings management with high-quality audit services in environments characterized by weak internal controls. Additionally, it highlights the conditions required to establish equilibrium in strategies like informative earnings management with low capital costs and informative earnings management with low-quality audit services within environments boasting strong internal controls.

Therefore, the monetary and fiscal authorities must have the necessary coordination and coordination in implementing their policies in order to achieve better results. On the other hand, the game theory is one of the concepts that has many applications in different sciences and fields. Game theory is of particular importance in economics, since it analyzes the interaction of individuals and their decisions. Thus, in the present study, the coordination of monetary and fiscal policies in the long run and its effect on macroeconomic variables are investigated according to a mathematical model. Accordingly, the interaction of monetary and fiscal policies are taken into consideration in the form of differential games with respect to the risk premium. On the other hand, the method of solving the game by Stackelberg game and the mathematical method is to solve the method of optimal control of Pontryagin's principle. In this regard, the results show that the interaction of monetary and fiscal authorities in the fiscal leadership creates better consequences in the society than the monetary leadership so that the fiscal leadership will decreases the government debts further and brings the debts closer to their desired level. On the other hand, if the policy makers consider the longer-term horizons for applying their policies and lead to the reduced risk premium, reduced target budget deficit and the real interest rates by proper policy-making, they can reduce the level of government debt and thereby the society will be in a better situation.

By acknowledging the international relations after the collapse of the Soviet Union, the world is practically ruled by a single-polar and despite the presence of China, Russia and the European Union in some global competition, still the hegemony of Washington almost exist. This article in response to the question of "The future of international order in the horizon of 2030?" has attempted to advance the global order based on the Games theory. Authors by using the " Scenario " method, argued that due to the constant effort of the States and a new actors such as India and Brazil to gain power in political, economic, cultural and military, global order will be changed. On the other hand, the USA's efforts to safeguard its hgemoni will cause the actor to maintain its focal focus, as a result of the current single-polar system to a single-multi-polarization system with the aforementioned focal classification and multi-focus (China, Russia, European Union, India and Brazil) will be changed.

In this study, the method of super-efficiency and cross-efficiency is used to rank the efficient branches of banks before the cooperation phase. Then, in the cooperation phase, each efficient branch is considered as a player and the subdivisions of the efficient branches are considered as a coalition, and the problem is examined using the method of cooperative game theory and Shaply value. In this study, the efficiency change variable shows the impact of each efficient branch in different alliances. From the total variable of efficiency change of efficient branches in each coalition, a characteristic function called profit from the coalition is introduced. The value of this characteristic function is determined for all possible alliances and Shaply value is introduced as the solution of this cooperative game and the ranking of efficient branches is presented in terms of cooperation. The resulting model is implemented on a case study and the ranks of efficient branches are compared in the super efficiency method and cross-efficiency (before cooperation) and Shaply value method (after cooperation).

Game theory provides a formal analytical framework with a set of mathematical tools to study the complex intersections among rational players (Osborne, 2004). Several approaches have been produced to the Portfolio selection problem, which became popular among researchers with the article of Harry M. Markowitz, published in Journal of finance in 1952, which occupies an essential place in the literature. Canonical Coalition Game Theory is among these approaches. In this paper the optimality of a portfolio partnership which will be created by each player’s strategies (stocks) with identical targets but different Beta capabilities will be examined first with a zero-sum game and then with establishing a coalition among different Beta groups(players). The obtained optimal gain will be distributed to each stock using Shapley vector. As a result the performance of the model’s portfolio was positive and better than market performance which resulted negative return during testing period. Manuscript profile -

In oil countries, abundant rent of oil income for government shapes the economic incentives of the political institution in such a way that provides special interests through public resources. While in the free market, the pursuit of private interests will lead to public welfare. Such a different approach in some oil countries provides the context of limiting and continuous interfering in the market mechanism, so it leads to a decrease in economic growth. Due to the importance of determining the real exchange rate in achieving the desired economic growth, in this article attempt to investigate the impact of political institutions on economic growth in an oil country. The game theory method used to substantiate the presented concepts. In this regard, the different motivations of the policy makers (as political institutions) of the oil countries in determining the exchange rate investigated. The reaction of entrepreneurs to this policy in choosing the level of investment considered as an indicator of economic growth. Based on the results, ellits in motivation of maximizing government revenue determine the optimal exchange rate. Assuming economic competition, they tend to misalign exchange rate in order to weaken competitors. Adding the assumption of political competition will lead to higher exchange rate misalignment and further weaken economic growth. Manuscript profile -

At first glance, the strategy of Hakim Ferdowsi is extracted, who doesn't want to give a free ride to the poets of future centuries after Rostam was killed in Shahnameh. The Ferdowsi and future poets game is a static and strict sequential game that is modeled using the 2x2 game theory atlas table. On the other hand, the game of Shoghad and Rostam using the strategic game model, after designing the strategies of the players, their earnings It has been calculated and analyzed in different situations according to the game environment. This 2x2 game is one of the static and strict sequential games It is hegemony. According to the table of this game, player p1 (Shaghad) who uses the conditions of the game to deceive player p2 (Rostam) and the game implemented in order to achieve his desire. One of the most important results of this article is to prove the deep thinking of Ferdowsi's strategic thinking, which as a strategist, it has been discussed and reviewed. Manuscript profile
