Description

technical field [0001] The invention relates to the technical field of lead time prediction methods, in particular to a lead time algorithm for dynamic service levels. Background technique [0002] In the make-to-order production system, the lead time is an important factor affecting the competitive advantage of the enterprise in the market. Based on the lead time management to rationally allocate resources, improve enterprise efficiency, save production costs, and achieve the goal of reducing costs and increasing efficiency, it is the next development direction of the enterprise. [0003] Different parts have different processing procedures, and the man-hours required for each process are also different. At the same time, the expected service level of each type of parts is also different. And since service levels are also dynamic based on changes in parts delivery levels, lead times should also be dynamic. How to accurately predict the lead time of various parts based on ...
