Design of a System Dynamics Model (SDM) to Evaluate the Supply Chain of Biological Products

Abstract

Today, organizational agility in a competitive business environment has become the primary principle of success. In the supply-chain management of any organization, its suppliers play an important role in achieving this significant goal. Therefore, the importance of evaluation in selecting and cooperating with suppliers plays a noteworthy role in increasing the chances of success. Meanwhile, identifying the supplier's evaluation indicators in a dynamic and uncertain environment has become a major challenge for managers. This article tries to provide an accurate and reliable solution to this important challenge based on the design of a System Dynamics Model (SDM). Thereby, the main purpose of this paper is to provide a model for evaluating suppliers in the biological supply chain. Then, the reliability and accuracy of the proposed model, are evaluated with several statistical tests. Finally, the performance of this model is shown in the supply chain of a vaccine and serum Institute. The results obtained, both in the tests and in the case study, all indicate the model's ability, reliability, and high accuracy in evaluating suppliers.
