Dynamic Analysis of Ordering System in the Supply Chain with the Dynamics of Systems Approach

The supply chain is a dynamic system that includes all activities related to the creation and delivery of a product, from the raw material stage to the final customer. Sapco's supply chain management needs future decisions and the design of new capacities with a comprehensive and interconnected approach. One of the management tools based on this approach is the system's dynamic knowledge. This science has the ability to simulate the supply chain, with the help of this simulation, the uncertain outcomes of decisions are revealed. An analysis of the fluctuations in the behavior of customer orders can provide a key role in predicting customer demand, sales, timely delivery, sales staff adjustments, and other factors. In this paper, the dynamic analysis of the order system in the supply chain with the dynamics of the system is examined. In this paper, based on the principles of the dynamics of the system, following the statement of the ordering system problem in the supply chain, the hypotheses that give rise to the problem are explained; then the dynamic model related to the problem of fluctuations in the ordering system of presentation It will be. first, the main variables were identified and their relationships were formulated in the form of Ali rings, then, by designing the main model, in the form of flow accumulation chart, was simulated in the software. After designing and simulating the final model, validation tests and sensitivity analysis were performed on the model that showed the validity of the model.
