Method & Evidence

AimTo develop and evaluate a hybrid optimization strategy for supply chain routing and scheduling that enhances efficiency and reduces computational time.
MethodComputational modelling and simulation
ProcedureA distributed hierarchical model was designed, incorporating modules for routing/sequence optimization, virtual clustering, and order scheduling. A multiple population search strategy (MPSS) was developed, combining genetic algorithms (GA) with tabu search (TS) to adaptively adjust GA parameters (crossover and mutation rates) during the search process. The MPSS was used to optimize routing selection and operation sequences within a supply chain context.
