And based on assumpt ion of ret urns arrival time of obeying Poisson dist ribution, returns production employing lot-size process and nonzer manufact uring/ re- manufacturing lead time, rat ional cost funct ion of inventory cont rol w as established. Genetic algorithm was applied to solve the inventory cost function so as to obtain the optimization solution of inventory checking periods, safe in- ventory points, product ion lot-sizes and process lot-sizes of returns production. Feasibility and validity of t he pro- posed method w as proved by an example, and inf luence of manufact uring/ remanufacturing lead time on enterprise invent ory control strategy was
