面向订单的航空制造业多工厂生产与运输综合计划模型

An integer programming model is built to solve the integrated planning problems including order allocation, components and parts processing, product assembly and product transportation in aviation parts integrated manufacturing environment with multiple heterogenic discrete manufacturing plants. The objective of the proposed model is the minimization of the total cost in the whole process of production and transportation. The proposed model handles the order allocation problem through constructing the product shipment constraint rather than separately introducing order allocation decision variables or adding order dimensions to the production and transportation decision variables so as to reduce a large number of unnecessary decision variables, which significantly reduces the complexity of the model and improves its practicability. The effectiveness of the proposed model is confirmed by an instance from an aviation manufacturing enterprise.
