Abstract: According to the characteristic of product discrete random demand and limited production capacity,the production planning optimization problem of multiple products in same assembly line was researched by considering the switching costs setup costs,holding costs,and backlogging costs.Through building the production schedule optimization method,the recursive formula and dynamic programming algorithm of solving model were designed.The example analysis was used to demonstrate that the proposed method was available for mechanical equipments enterprises to make production planning of multiple products in the same assembly line.

Key words: engineering machinery assembly, multiple products production planning, same assembly line, capacity constraint, optimization
