Designing a Model and Simulating the Production Chain of the Metal Industries in a Dynamic System Approach (Case Study: Shablon Tajhiz Company)

Supply chain includes all the activities required for offering a product or service to the final customers. Adopting the foresaid approach to supply chain, the construction and distribution functions are added as a part of the goods and service flow to the chain. In fact, supply chain incorporates three areas of procurement, production and distribution in this approach. Since the supply chains might be extremely variable from an industry to another and from a company to another due to the unique complexities and delicacies of each manufacturing and service organization, the present study tries performing a comprehensive analysis of the success of the supply chain in the metal industries thereby to investigate and explore the rings influencing the performance of the chain and attain the comprehensive pattern of the industries’ success through behavioral analysis of the obtained results. In line with this, in order to be able to perform real simulation of the model and design an optimum scenario and meanwhile, analyzing the status quo of the metal industries in Kermanshah Province, Shablon Tajhiz Company was selected as the pilot study of the project and the rings influencing it were identified and investigated within the format of the “extant rings” and “missing rings”. Since the nature of these rings and, subsequently, the variables constituting them change in the course of time in the real world, to consider the dynamicity conditions and their mutual effects on one another, use was made of a dynamic system approach for simulating the model’s structure. The results were examined and verified via sensitivity analysis of the findings. It is worth mentioning that the analysis and delineation of the results were carried out using Vensim Software.
