JIT (Just In Time) production supply system and control method thereof

Abstract

The invention discloses a JIT (Just In Time) production supply system and a control method thereof. The control method of the JIT production supply system comprises the steps of: when materials are taken or a production plan is changed, detecting a demanded quantity of of a next order for materials; detecting a remaining inventory level of the materials; detecting a logistics quantity of the materials; and comparing the demanded quantity of the next order for the materials with the remaining inventory level and the logistics quantity of the materials, and according to a comparison result, regulating material production. According to the control method of the JIT production supply system, which is disclosed by the invention, links of material production, material transportation and the like can be regulated in real time according to information of the demanded quantity of the next order for the materials, the remaining inventory level of the materials, the logistics quantity of the materials and the like so as to ensure the minimum inventory, ensure real-time follow-up of a production order and material transportation, ensure integral coordination of the production supply system, improve maximum efficiency operation of the JIT production supply system on the basis of reducing the inventory, reduce production cost and improve production efficiency.

Description

technical field [0001] The invention relates to a material processing production system, in particular to a JIT production supply system and a control method thereof. Background technique [0002] Poor planning ability, control ability and communication and coordination ability of the enterprise can easily lead to the following phenomena: [0003] 1. Frequent downtime for materials: due to unplanned production or unplanned materials, the progress of materials often cannot keep up, resulting in frequent downtime for materials. [0004] 2. In production, there is a full meal and a hungry meal: because the work is often stopped to wait for materials, the delivery period will naturally be shortened when the materials arrive, and the production time is insufficient, so we have to work overtime to catch up with the goods. [0005] 3. Inaccurate material planning or poor material control, semi-finished products or raw materials cannot be connected, what should come does not come, ...
