Production Planning Based on Multi-Level Process Flow
ABSTRACT
To improve correctness and reasonability of the enterprise production plan and subsequent promote planning and control capability of enterprises, this paper proposes a production planning method based on multi-level process flow. First, this paper proposes the space-based multi-level process flow idea and establishes mathematic model and formalized expression of multi-level process flow according to the actual division of the enterprise’s production space and manufacturing process of products in space units at different levels. Meanwhile, this paper proposes the concepts of the JOB lead time, POS lead time, ACC lead time and shop lead time, and gives the detailed computing method of different lead times. Based on above work, this paper analyzes mapping of process flow and production plans, and expounds specific computing method of flow unit delivery time at different levels. Finally, this paper proves correctness and feasibility of this idea and method via the actual cases.
