资料3（Information 3） Five. Lead time Figure 5 details the lead time involved, which is started by processing the lead time of material processing, to finished products so far. Before production Set aside time from raw material purchase to finished product storage. The customer lead time starts with the customer order until the customer receives the finished product . Customer orders issued up With the input of receiving orders Processing of orders The production plan, draft The procurement of raw materials, increase The operation time,, We carry out the material receiving Inspection, storage, handling, Work orders issued, Gu, The supply of customers, increase 1 / set, transported to the workstation of students Wait for the purchase, production, processing, The processing of before, before, Wait, set, set, and handling And in handling, chrysene, semi-finished products, when stacked, when the work of Of moving to the next workstation, between, between the front of Wait, we carry out the processing of When we carry out processing,, Wait, handling, we carry out. Whether or not, to complete the processing work, we carry out - is,,, Here, we carry out Handling of finished products into the case: The storage of Out of finished products Packing, shipment The transport of Customers receive products: Figure 5 definition of lead time detail Cutting customer lead times is an important tool for achieving high output manufacturing management, but how should we reduce lead time? Machinery processing industry The research shows that the time spent in machining only accounts for 5% of all lead time, while machining lead time only accounts for pre production lead time Between 30%, therefore, processing time accounts for only 1.5% of the lead time. A manufacturing firm has made a thorough investigation of its lead time Only 121 minutes were spent on processing and assembly operations when the lead time of the 22 perimeter customer order was found. Thus triggering widespread management T
