Heavy machinery enterprise as research object, this paper analyses the feature of production scheduling for one-piece discrete manufacturing and proposes the collaborative multi-objective optimization problem. Based on the improved Taguchi loss function, nonlinear relationship of quality, delivery and cost is established. And the multi-objective collaborative optimization model of production scheduling is created as well as synthetically considering of one-piece discrete constraints. The effective solution was explored for solving the model Integrating simulation technique and genetic algorithm. Further, through the enterprise empirical study, the practicability and validity of the model and algorithm is verified. This study provides scientific method of production scheduling for one-piece discrete and improves the efficiency and scientific of the production scheduling.
