This review examines key concept and approaches used in this research. The review begins with the brief discussion of Just in Time and its impact on enhancing Supply Chain performance, later focus on the principles of JIT and its role on enhancing Supply Chain performance.
1- Just-in-time manufacturing system has long been an integral part of the supply chain management. It plays a vital role in enhancing the supply chain processes of any company and is very important to be looked upon in a very careful manner. In this literature review, we also look at the role of JIT in the supply chain from three perspectives; quality, buyer-supplier relationship and ...view middle of the document...
Any variations in volumes are accommodated by establishing a level-average demand rate. The practice of Heijunka also eliminates muri – overburden or strenuous work that can also lead to safety and quality problems. Both mura and muri are thought of as types of muda, or waste, and should be eliminated.
ELIMINATION OF WASTE – MUDA
Elimination of waste
Waste – defined as anything that does not add value – includes things that might not normally be considered as waste such as overproduction, holding too great an inventory, the need for rework, and unnecessary movement, processing and waiting.
Takt Time-The Heart Beat of Production TIME – THE HEARTBEAT OF PRODUCTION
Time planning is central to TPS. Takt is the rate of customer
demand – essentially, what the market is requiring be produced.
Takt time is the term given to a work-cycle that fulfils each
customer’s demand. The key is that the work-cycle should be
synchronised with demand to avoid under- or overproduction.
Takt time determines the flow-rate and allows the calculation of
how much work can be accomplished. Optimisation of takt time
reduces waste and inefficiency by eliminating the risk of time
delays, or excess production, throughout the process.
Takt time and heijunka mean having the ability to be flexible
according to demand and ensuring the process is smooth,
continuous and measurable.
In order to have flexibility and efficient, smooth workflows, it is
necessary to have the right things at the right place at the...
