JIT Darshan
The roots of the JIT system can probably be discovered in the Japanese environment. There are underlying limits of location deficiency and lack of natural resources in Japan. Hatred has been born in the japanese towards every kind of waste.
They see scrap and re-work as waste and so strive for the best quality. They firmly believe that inventory storage makes a waste of place and as a result of this, valuable materials and capital trapped. Any item that contributes to the value of the product on rot is seen as a waste. Thus, it is quite natural to develop JIT philosophy in Japan. Apart from eliminating waste, JIT has another important feature that uses the worker’s full capacity. In the JIT system, it is taken responsibility to produce quality pan on time to support the next production process on workers.
1. The purpose of the JIT system is to reduce cost, improve profits and return on investment through inventory reduction and improve quality. Workers’ participation and elimination of waste are means to achieve these purposes. Therefore, JIT manufacturing is as a comprehensive philosophy of continuous improvement that includes three mutual auxiliary components, e.g., TF: 153TP FT Division and Participation.
2. Whole quality control absolutely the conditions required in time flow The PF JIT Working Process List is the basis on which JIT rotate. Its aim is to reduce the manufacturing lead time obtained through a huge reduction in the work process, resulting in a seamless flow of the production of small lots.
JIT needs some changes in production, plan and control. They are as follows: the production programme has to be stabilized. The production capacity of the work centers is to increase.
Improve product quality. Preventional maintenance is to be started. Supplier relationships should avoid maintaining amicably inhibition of supply. Workers are cross-trained and multi-efficient.
Components of JIT
The components of JIT are the following: eliminating waste- the central component of JIT is to eliminate all types of waste. Waste is finished by coordinating the operational flow, by balancing the road imbalance.
Designing the factory layout that eliminates content management delays, reduces set-up time, increases production rate, improves productivity and quality by removing defects, etc. unnecessary speeds through time-and-speed studies,
Problem-solution and constant improvement- There are some built-in safety factors like quality standard is expected from each material, expected to reach the scheduled time of each part and to the scheduled place, and each machine is expected to work in line with expectation. without interruptions through preventive maintenance. In addition, the production process is ensured constant improvement so that potential manufacturing problems can also be reduced.
Mutual faith in training people in JIT-JIT has been envisaged and team work among employees. Workers have been empowered to make JIT successful. Workers are trained in the JIT process, which facilitates workers to successfully assimilate the JIT concept.
Bridge-Production Control- JIT separates itself as a bridge-production system while MRP is a push system. Production in the bridge system is limited to only those who are required in the next stage of production. It facilitates the product’s batches to move from one condition of production directly without storing in inventory.
Benefits of JIT
The benefits of JIT are the following:
Like the list between the steps of production have decreased considerably, inventory build-up isn’t at all. Awareness of problems and their causes has increased among the employees and their solutions are facilitating.
JIT provides constant improvement in each area of activity through Kaizen. Time taken to complete the finished product has significantly reduced due to set-up time reduction, which has helped the organisation to effectively withstand competition and increase its market share.
Manufacturing functions have been streamlined and have faced the problem to some extent. As the inventory grows, the place is considerably reduced and the cost of car crying is saved.
