Resource Conflicts Resolution of Sophisticated Production Lines During the Process of Product Renewal
针对复杂产品更新中生产线的资源冲突问题，构建了基于合作博弈协商机制的多项目资源冲突解决模型，通过反馈调节和混合遗传算法优化调度，案例显示可节省77.84%的延迟和调度成本，利润提升10.82%。
There exist a variety of resource conflicts due to resource-constrained in production lines during the period of renewal of sophisticated products manufacturing, probably leading to production delays and resource wastage. With respect to the resource conflicts of the resource-constrained multi-project scheduling problem in sophisticated product lines, we construct a multi-project production line resource conflict resolution model, design a feedback regulation and a hybrid genetic algorithm based on the cooperative game negotiation mechanism, which cover four stages starting from the manufacturer receiving the orders of original and upgraded products, taking into account of resource reallocation, resource sharing, and seeking help from emergency suppliers, to respond highly to the dynamics of customer orders and optimize production systems, achieving intelligent advances. The case results show that the proposed method can save up to 77.84% of the delay and scheduling cost, and these savings can allow the manufacturer to increase profits by 10.82% due to shortening the production delay. The current work not only helps manufacturers of sophisticated products to improve their production efficiencies and reduce the delay cost, but also provides a certain basis for future managers to make production management decisions.
