According to the characteristics of flexible job shop scheduling (FJPS), a mathematical model was established minimize maximum completion time, and an improved genetic algorithm proposed solve problem. A variety heuristic methods are used improve quality initial solution. The parallel double-chain encoding is designed optimal insertion method Two crossover methods, namely IPOX multi-point cross...

Flexible job-shop scheduling problem (FJSP) in the field of production scheduling presents a quite difficult combinatorial optimization problem. Machines are mostly considered to be the only resource in many research projects dealing with FJSP. In actual production, there are many other factors which influence production scheduling, such as transportation, storage and detection. If machines are...

Research on the Flexible Job Shop Scheduling (FJSP) problem in manufacturing process of aircraft engines has been carried out. It is found that there are real requirements such as order mandatory nodes and equipment selection current job scheduling process. Order node means some important orders must be delivered time at a certain point time, which often affects quality workshop results. In add...

A hybrid flow shop (HFS) is a generalized flow shop with multiple machines in some stages. HFS is fairly common in flexible manufacturing and in process industry. Because manufacturing systems often operate in a stochastic and dynamic environment, dynamic hybrid flow shop scheduling is frequently encountered in practice. This paper proposes a neural network model and algorithm to solve the dyna...
