Effectiveness Of Whipping Effect in Supply Chains of the Iranian Defense Industry and Modeling the Reduction of Its Effects Based on the Method of System Dynamics in the Direction of Resistance Economics

Considering the high importance of supply chains and their fundamental role in defense industries, improving the effect of the amount in reducing costs and increasing the performance of the defense industry of the Islamic Republic of Iran is undeniable. The present study tries to obtain an approach to improve the performance of the supply chain. To this end, the effect of pneumatic phenomenon on multi-dimensional supply chains was calculated based on a small time series and its mathematical model was obtained. Then, on the effect of the order period, the purpose of the order and the net storage value of the target was discussed and the stable and unstable areas of the equations were obtained. Also, the effect of pneumatic phenomenon on supply chains was calculated using simulation and attitude of time series based on appropriate algorithms. To validate the problem, the results were compared with a case study. Also, the effect of pneumatic phenomenon on the current case study, optimized by optimizer software. As a result, it turned out that the use of a time series model as a demand pattern and daily inventory inspection of distributor and shipping on a daily basis for completing their inventory reduces the decrease in the pure effect in the defense industries of the Islamic Republic of Iran. In addition the findings of the research indicated that the whipping error extent is variable between 0.17 and 11/40.The average error extent for the distribution and production sections is and 7.34.
