JIT - Just-In-Time

"Precisely in time" - an alternative MRP management system for materials in production at which components from the previous transaction (or from the external supplier) are delivered while they are required, but not earlier. Batches of components are so small as far as it is possible (it depends on runtime and stability of a cycle of delivery). The JIT system makes the greatest success at the enterprises of average scale with serial type of production where standard products are made with a high speed with a continuous flow of materials and component parts. In this situation procedures of planning and control are sufficiently standardized and simple. On the large, hi-tech enterprises where the procedure of planning and control of production processes is difficult, JIT is practically not used.
