Research on a JIT scheduling problem in parallel motorcycle assembly lines considering actual situations

Abstract

After the research of schedule problem of one kind of flexible motorcycle assembly lines, a kind of parallel conveyor belt flow shop schedule model using JIT (just-in-time) is given. The impacts of the different max process paces of different work pieces in different stations are considered. Besides, some actual situations, including unstable information and structural constrain, are also considered. Then a kind of improved artificial fish swarm algorithm based on polar coordinate coding is presented to optimise this schedule model. Lastly, this model is tested with the real data from two motorcycle assembly lines, and the result shows that the total production fee is reduced.

Keywords:

• scheduling model
• just-in-time
• artificial fish swarm algorithm
• co-ordinate coding
