Implementation of a multiobjective planning model for flexible manufacturing
Abstract
A flexible manufacturing system (FMS) is an attractive alternative to the conventional batch manufacturing system because it is capable of producing a variety of products at prices that approach those attainable through mass production. However, the versatility and complexity of an FMS make production management in an FMS environment not only more difficult but also more essential to achieving its full potential than in the conventional manufacturing environment. The decision making process for production planning in an FMS usually involves multiple conflicting objectives. A multi-objective oriented model can thus be effectively applied to the production planning problem of an FMS. An important advantage of the multi-objective oriented model is its ability to yield optimal solutions in a reasonable amount of time. The primary objective of this research is to develop a goal programming (GP) model for production planning and scheduling problems in a real-world FMS so that the model can be used to support decision makers with multiple conflicting goals. The GP model incorporates various production goals of the FMS and analyzes them according to the provided preference mechanism. To better understand the disciplines related to this research, literature in those disciplines was surveyed. The goals and their relative priorities were determined through an interview with the production personnel working in the FMS. Once the GP model was constructed and implemented based on the data collected from the FMS, the validity of the implementation results of the model was tested by simulation. Sensitivity analysis of the model was then performed to analyze the effects of parameter changes on the overall system performance.
