Tedarik zinciri yönetimine hiyerarşik üretim planlaması yaklaşımı

In today?s competitive environment, enterprises should make quick and accurate decisions. Our focus in this study is a supply chain consisting of many stages. As a supply chain may be very complex, modeling and solving such a big problem may take too much time. Our intention is to find a way to shorten the decision process. We have adopted the hierarchical production planning approach to our problem in order to simplify the problem. Hierarchical approach is proposed as an alternative to the approach monolithic. It is proposed by Hax and Meal, for the first time, to solve complex production planning problems. The hierarchical planning is a convenient model to plan and manage the incertitude and complexity inherited in the nature of supply chain and thus to minimize the costs and decrease response time to market. In the hierarchical approach, global problem is decomposed to simpler sub-problems. All of these sub-problems require a planning and modeling that corresponds to a decision making layer. So, establishing a hierarchical production planning system means choosing a number of decision making layers, a model for each layer and finally a method to coordinate the decisions flow and information feedback between the layers. Using the hierarchical production planning approach to solve supply chain management enabled us to find a way to solve complex problems in a reasonable amount of time. This method should have lots of application in real world situations. In today?s competitive environment time is very precious and the methods provided in this study will let use it more efficiently.
