Focusing on the order delay problem in the process of production, a control model based on the Theory of Constraints (TOC) and Critical Path Method (CPM) are proposed with the analysis of control method, in which it is composed of custom design module, manufacturing management module and optimizing control module. And with the processing costs minimization as objective function, a control mode for production is put forward for minimization of resource consumption and maximization of production. With the case study, it is found that the proposed control mode was effective and applicable.
