Resource Conflicts Resolution of Sophisticated Production Lines During the Process of Product Renewal

There exist a variety of resource conflicts due to resource constraints 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 multiproject scheduling problem in sophisticated product lines, we construct a multiproject production line resource conflict resolution model, design a feedback regulation, and a hybrid genetic algorithm based on the cooperative game negotiation mechanism, which covers 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 delay cost but also provides a certain basis for future managers to make production management decisions.
