JIS is an extreme manifestation of JIT situation, for the distribution of parts of the fine requirements of the higher, the difference between the two is: through JIT to achieve no inventory or minimum inventory, that is to say, the JIT approach should also take into account a certain amount of supply chain buffer inventory and safety stock, JIS is the OEM what parts you want to send what, and some of the OEMs will require in accordance with the assembly process for the The parts are sorted according to the assembly process.
Just In Time (JIT), also known as stockless production (stockless production), zero inventories (zero inventories), one-piece flow (one-piece flow) or supermarket production (supermarket production)
The JIS system is a system that allows the supply chain to deliver a certain amount of buffer stock and safety stock, and some OEMs will require parts to be sorted according to the assembly process.
JIS, abbreviation for Japanese Industrial Standards, developed and reviewed by the Japan Industrial Standards Survey. It can also denote a function.
The basic idea of the JIT production method is to "produce only what is needed, when it is needed, and in the amount needed," i.e., to pursue a production system in which there is no inventory, or in which the inventory is minimized.
The basic idea of JIT is the planning and control of production and the management of inventory. Therefore, the JIT production model is also known as "Lean Manufacturing." The core of JIT is the pursuit of an inventory-free production system, or a production system that minimizes inventory. To this end, a series of specific methods including "Kanban" have been developed, and a unique production and management system has been gradually formed.
Expanded
JIT takes just-in-time production as its starting point, first exposing overproduction and other wastes, and then eliminating and adjusting equipment, personnel, etc., to achieve the purpose of reducing costs, simplifying planning and improving control. In terms of production site control techniques, the basic principle of just-in-time production is to produce the right number of parts or products, at the right time, instantaneously.
It will be the traditional production process of the former process to the latter process delivery, changed to the latter process according to the "Kanban" to the former process to pick up the goods, Kanban system is the core of just-in-time production site control technology, but just-in-time system is not just Kanban management. One of the foundations of JIT is balanced production, i.e., manufacturing products evenly so that logistics flows in a balanced and equalized manner between operations, production lines, processes, and factories. To achieve equalization, monthly and daily plans are used in JIT, and the plans are adjusted in time according to changes in demand.
Japanese also translates JIS as ジス, which is developed and considered by the Japan Industrial Standards Survey Committee (JISC) organization, and is one of the most important and authoritative standards at the national level in Japan. According to the provisions of the Japanese Industrial Standardization Law, JIS standard object in addition to pharmaceuticals, pesticides, chemical fertilizers, silk, food and other agricultural and forestry products to develop a special standard or technical specifications, but also involved in various industrial fields.
The contents include: product standards (product shape, size, quality, performance, etc.), method standards (test, analysis, testing and measurement methods and operation standards, etc.), basic standards (terminology, symbols, units, priority numbers, etc.). Specialties include: construction, machinery, electrical, metallurgy, transportation, chemical, mining, textile, paper, medical equipment, ceramics and daily necessities, and information technology.
