Abstract: This paper focuses on the allocation and scheduling problem in divisional seru production system, which is a new production mode originating in Japan and has been proved to be both efficient and flexible in practice. According to the production process, the allocation and scheduling problem considered in this paper includes worker allocation, operation allocation and order scheduling. A bi-objective nonlinear model is established to minimise the total completion time and optimise the production balance. Subsequently, since seru scheduling is a natural NP-hard problem, therefore, the solution method which combines the clustering analysis and genetic algorithm is designed. Finally, the numerical example is presented to verify the effectiveness of proposed model and solution method. The experimental results show that the satisfactory production scheduling scheme in divisional seru can be obtained effectively, and the performance of the divisional seru production system is better than that of the assembly line.
Keywords: divisional seru; worker allocation; operation allocation; order scheduling; genetic algorithm.
