Structured System Analysis Methodology for Developing a Production Planning Model

Aggregate Production Planning (APP) is a medium term Planning that links between the long term planning and the short range planning. Although there are many models developed by the researchers in this area, few of them are being implemented. This reason was the motive to develop a model in a different way than the traditional models used to be developed. The Integrated Definition level 0 (IDEF0) is used in this paper to represent the development of a typical APP model. The IDEF0 shows the model formulation using goal programming (GP) including identification of the model goals and model constraints, preparation of the model format, and finally solution of the model using a Genetic Algorithm (GA) approach. The IDEF0 as a structured methodology enhances the model development process, and make the relationships between the objective function and constraints crystal pure, which in consequences enhances the problem representation and solution procedure.
