        Over the past two decades, PC speeds have increased from a few instructions per second to several million instructions per second. The tremendous speed of today's networks as well as the increasing need for high-performance systems has made researchers interested in parallel and distributed computing. The rapid growth of distributed systems has led to a variety of problems. The most important problem that has been addressed by many researchers is the task allocation in such environments in order to obtain effective system efficiency. The task allocation problem is, except in a few specific cases, an NP-complete problem; so, heuristic methods are used to achieve suboptimal solutions in the desired time. Although different methods have been used in research, finding an effective and efficient method for this problem is still needed and desirable. This study used a parallel genetic algorithm to find the optimal solution for allocating a graph of tasks to the processors in a distributed system. The results showed that the proposed algorithm can provide optimal or near-optimal allocations for problems of different sizes. Also, the proposed method was able to solve problems of large and medium-size in a much faster time than traditional genetic algorithm with super linear speedup. Manuscript profile

        Thermal power plants play a major role in the production of air pollutants, with significant consumption of fossil fuels. Sulfur oxides are among these pollutants.So far, none of Iran's thermal power plants have been equipped with technologies to reduce and control sulfur oxide emissions. Due to the necessity of reducing pollutants caused by fuel combustion in power plants of the country, and imposing high social costs due to the excessive emission of pollutants,This paper seeks to play an effective role in managing the emission of this pollutant by presenting a strategy to prioritize and select sulfur oxide-lowering technology with an investment approach in Iranian thermal power plants. . In this study, fuzzy Delphi technique was used to select the criteria for effective investment in technology and Simultaneous evaluation of criteria and alternatives (SECA)was used to rank SOx-lowering technologies. The results showed that dry scrubber technologies, regenerable process, corona discharge, sorbent injection process and absorption technology were the first to fifth priority of of technology selection, respectively.

        In a supply chain network, implementing a sound management system in the process of shipment can lead to lower costs and increase customer satisfaction by improving the flow of products. Therefore, in this study, a multi-objective mathematical model was presented and solved to optimize the vehicle routing problem by locating the warehouse in the green supply chain while simultaneously receiving and delivering goods. The main limitations considered in this model include manufacturers' capacity, vehicle capacity, vehicle selection based on green supply chain criteria, vehicle routing and cross-stock warehouse location to minimize costs and fuel consumption and reduce pollution. In this case, the goods received from suppliers will be delivered to customers on the route after being categorized in a cross-stock warehouse or delivered directly to customers if necessary. It is assumed that product pickup and delivery are allowed on a single route and there is also a planning horizon for receiving products on the go. In general, the model aims to determine the best route in the green supply chain mode and the optimal number of vehicles used in the distribution network so that the total operating and relocation costs are minimized. The proposed model was validated using Gams software and Comprehensive Criterion Method and the results were evaluated in accordance with the articles presented in this efficient field and compared to similar articles.

        The present paper introduces a model by investigating studies that have applied Agent-Based Modelling to improve organization system problems. The model is made of two parts (a conceptual model and an Agent-based model) and their interactions. The conceptual model structures the simulation by determining input, output, modelling activities, and system boundaries. Then, the computer model based on the validated and verified conceptual model was built. For practical application of the model, employees’ dissatisfaction of OG companies over promotion system was modeled. Regarding the agent based simulation of promotion process, modelling team with multiple perspectives involving managers, employees, and modelers suggest three scenarios to address the problem. The first scenario suggests financial compensation for employees; the second scenario recommends one grade increase in all the company job-grades; and the last scenario is a combination of them. The results of this investigation indicate that by implementing the first, second and third scenarios the overall dissatisfaction of the company will decrease 57, 42, and 78% over 10 years respectively. Finally, the modelling team proposes the last scenario for implementing in company. Manuscript profile
