Pull System for JIT Production

Toyota’s JIT production is a method to adapt to changes due to disturbances and changes in demand by making all the necessary processes to produce goods at the time it takes the required amount. The first requirement for JIT production is to make all the process of knowing the exact timing and amount needed. In the usual system of production control, the above requirements be met by issuing a variety of production schedules on all the process: The process of manufacturing spare parts and also on the line of rafts. This process produces spare parts spare parts in accordance with the schedule, using a push system, meaning the former to supply spare parts to the next process. However, this method will make it difficult adjustment quickly to changes caused by disturbances arising in some process or due to fluctuations in demand. With ordinary systems, to adapt to various changes during the month, the company must modify the production schedules for each process simultaneously; the approach

JIT and Automation

Since the JIT system is used, usually only shows the possibility of automation in some respects. Because it is not uncommon for companies that use JIT to follow him with possession of advanced manufacturing technology. Automation company to: (a) increase production capacity, (b) increase efficiency, (c) improve the quality and service, (d) lower the processing time, (e) increase the output. Automation increases the ability to track costs on various products individually. as an example of FMS cells, is a fellow of the automated JIT manufacturing cells. So. some costs which are costs not directly in the traditional environment is now a direct cost.

JIT manufacturing

JIT manufacturing uses a more centralized approach than that found in traditional manufacturing. The use of JIT manufacturing system having an impact on: 1. Improving Traceability (Traceability) costs. 2. Improving the accuracy of product cost. 3. Reducing the need for allocation of central service costs (service departments) 4. Changing behavior and the relative importance of direct labor costs. 5. Affect the pricing system and process basic orders. The basics of JIT manufacturing and the difference with traditional manufacturing: 1. Compared with traditional JIT manufacturing. JIT manufacturing is a demand pull system (Demand-Pull). JIT manufacturing goal is to produce a product only if the product is needed and only for the number of requests of buyers (customers). Some differences with the traditional JIT manufacturing include: a. Low Inventory b. Manufacturing cells and Interdisciplinary Workforce c. Philosophy of TQC (Total Quality Control)
