Using Discrete Event Simulation in Supply Chain Planning
نویسندگان
چکیده
Supply chains are difficult to plan because they involve complex relationships and dynamically changing variables that influence supply chain performance. In this paper, discrete-event simulation (DES) is evaluated in order to identify its appropriateness as a technique in supply chain planning. A DES model was developed as part of a case study, and is used in this paper to determine whether DES is an appropriate technique for unraveling the complexity of supply chains. The DES model represents a retail supply chain focusing on order and material handling process behaviors, and is based on data from an on-site study of the retail supply chain. One result of developing and using the DES model is that insight into the system parameters and their interaction with their context is obtained. DES could be used for analyzing and evaluating dynamic aspects as well as the influence of variance on supply chains, which can be used to support decision making.
