Abstract

Since the whiplash phenomenon is an effective and decisive factor in supply chains; Therefore, an attempt is made to improve the performance of the defence industry of the Islamic Republic of Iran by controlling and reducing it. The current research tries to obtain an approach to improve the performance of supply chains. For this purpose, the effect of the whiplash phenomenon on multi-product, multi-stage and multi-level supply chains has been quantified based on time series, and a mathematical model has been obtained for it. In addition to that, other important and effective parameters such as the amount of target net storage have been studied. Also, the impact of the whiplash phenomenon on supply chains was obtained with the help of simulation and with the perspective of time series based on appropriate algorithms. To validate the findings, the results have been compared with a case study. Also, the effect of the whiplash phenomenon on the existing case study was optimized with the help of optimizer software, and as a result, it is found that the use of the time series model as a demand model and the daily inspection of distributors' inventory and the daily transportation of products to complete their inventory will reduce the whiplash effect. in the defence industry of the Islamic Republic of Iran. In addition, it was found that the daily inspection of the distributors' inventory and the shipment of the product on a daily basis to complete their inventory will have favourable effects.
