Chapter 15 Just In Time - Phrase invented by Kiichiro Toyoda - the first president of Toyota. There is conflict on what the actual English translation of what "just in time" really means. Taiichi Ohno quoted from the book says " 'Just In Time' should be interpreted to mean that it is a problem when parts are delivered too early". [21]
Kanban (Japanese: 看板 meaning signboard) is a scheduling system for lean manufacturing (also called just-in-time manufacturing, abbreviated JIT). [2] Taiichi Ohno, an industrial engineer at Toyota, developed kanban to improve manufacturing efficiency. [3] The system takes its name from the cards that track production within a factory.
Just-in-time manufacturing was introduced in Australia in the 1950s by the British Motor Corporation (Australia) at its Victoria Park plant in Sydney, from where the idea later migrated to Toyota. [16] News about just-in-time/Toyota production system reached other western countries from Japan in 1977 in two English-language articles: one ...
Mura, in terms of business/process improvement, is avoided through just-in-time manufacturing systems, which are based on keeping little or no inventory. These systems supply the production process with the right part, at the right time, in the right amount, using first-in, first-out (FIFO) component flow. Just-in-time systems create a "pull ...
Toyota's view is that production systems that vary in the required output suffer from mura and muri with capacity being 'forced' in some periods. So their approach is to manufacture at the long-term average demand and carry an inventory proportional to the variability of demand, stability of the production process and the frequency of shipments.
Just in sequence (JIS) is an inventory strategy that matches just in time (JIT) and complete fit in sequence with variation of assembly line production. Components and parts arrive at a production line right in time as scheduled before they get assembled. Feedback from the manufacturing line is used to coordinate transport to and from the ...
The relevance of his contribution has sometimes been doubted, but it is substantially confirmed by the opinions of his contemporaries, [2] [better source needed] many saw him even as a contributor to the fundamental concepts of TPS, such as Just-in-time, and the “pull” production system, which were created by Toyota and Mr.Taiichi Ohno and ...
This time range from the time the firm reorders the stock to the time the supplier provides the new stock is known as lead time. Thus a JIC inventory system tries to keep a minimum level of inventories just in case of emergencies, hence the name "Just In Case".
