Research on Remanufacturing Scheduling optimization with Uncertain Process

Aiming at a remanufacturing scheduling problem with uncertain process, a multi-objective optimal scheduling model is established to minimize makespan, total delivery delay and total equipment idle time. An improved multi-objective harmony search algorithm is proposed. The concept of individual similarity is proposed and used to measure the diversity of individuals in the harmony memory. The harmony memory considering rate and pitch adjusting rate are changed adaptively according to the diversity of individuals. The results of experimentation show that the way in this paper is feasible and effective.
