Aggregate production planning with fuzzy demands and fuzzy capacity
模糊需求和模糊能力约束的集约生产计划

By means of formulation for fuzzy addition and fuzzy equation,the production-inventory balance equations in single stage and dynamic balance equations were formulated as a soft equation in terms of a degree of truth and interpreted as the possibility level of which production and inventory plan met the fuzzy demand. The parametric programming model and best balance model as well as the interactive approach were developed to solve the FMAPP problem. This approach offers decision-maker an overall procedure in making a reasonable plan in different fuzzy environments.
