A Study on Productivity Model of Supply Chain in Industrial Units by System Dynamic Approach

In this decade, due to the current competitive environment, reputation of industrial brands is markedly dependent upon the performance of their supply chain. Therefore, it is necessary to examine the factors affecting their supply chain so as to increase the competitiveness of their chain. Productivity is among the most important factors in the advancement of industry and its evaluation requires the identification of its important criteria. Thus, using interviews with experts and industry executives and applying basic concepts of system dynamics, it was endeavored in this research to identify the effective factors in the productivity of supply chain including 27 variables and then suggest a model to evaluate the productivity of supply chain in industrial units. Once the model was implemented and analyzed by the simulation software Vensim, the responses were graded and the desired results were presented from among them.
