| Abstract: | Optimization of planning and scheduling problems in manufacturing system often falls into difficulties because of constraints of resources or contracts. Problems without enough constraints may produce a quite good solution. However, precise values of constraints are difficult to determine during the course of long dated scheduling. This paper applied a fuzzed nonlinear programming method to generate optimized production plan and searched optimized scheduling scheme with Genetic Algorithms (GA), together with the constraints of resources and contracts. Meanwhile, a calculating example solving planning and scheduling problem was given. |
