Characteristics Of Just In Time JIT

The JIT approach to manufacturing involves timing the delivery of resources so that they arrive just when needed. Inventory optimization models help the firm determine how many of which items in which sizes should be delivered to each specific store during twice-weekly shipments, ensuring that each store is stocked with just what it needs. Trucks serve destinations that can be reached

Jonah shows that they can use the same method to develop a release system for materials throughout the system. By knowing when the bottleneck parts will reach final assembly, the release of the non-bottleneck materials can be timed to coincide along the other routes. Then Jonah indicates that after load balancing is performed to meet market demand without excess production, the next logical step is to reduce the batch sizes to reduce the total capital commitment used during production. Reduction in batch sizes also reduces the total time spent in work-in-process. Less time spent in production increases the speed of throughput as well as a faster turn-around on customer orders. Shorter lead times result in better response to the market demands. (Jackson, Goldratt, Cox, & American Media Incorporated, 1995)

As a result of these benefits, the JIT system has been particularly effective for companies with a high customer demand on newly developed technologies such as computers. If the product is produced when required and as specified by the customer, this not only allows the customer to order exactly what they want with modern technology, but it also benefits the manufacturer who is guaranteed a return on the goods straight

4) Exploring the possibility of implementing JIT (Just in Time) system that can reduce the finished goods inventory at

Just in time is a manufacturing method based on pull system which means the raw materials are only delivered only when needed which reduces waste due to overproduction and lowers the storage rent e.g. warehouse storage.

Pull: The production system should be driven by the customer demand. Just-in –Time (JIT) approach is the adoption of the pull approach.

The just-in-time (JIT) inventory management is the process of ordering and receiving inventory for production and customer sales only as it is needed and not before. This means that the company does not hold safety stock and operates with low inventory levels. This strategy helps companies lower their inventory carrying costs by increasing efficiency and decreasing waste. Waste is anything that does not add value.

By taking a Just in time approach to inventory and product handling, companies can often cut costs significantly. Inventory costs contribute heavily to the company expenses, especially in manufacturing organizations. By minimizing the amount of inventory, you save space, free up cash resources, and reduce the waste that comes from obsolescence.

     Anybody who knows something about business had heard the term Just-in-time (JIT) inventory. It involves producing only what is need, when it is needed. The principle of Just in time is to eliminate sources of manufacturing waste by getting the right quantity of raw materials and producing the right quantity of products in the right place at the right time.(1) In this way, manufactures receive parts and materials “just in time” to meet the day’s manufacturing quota with hardly any extra.(3)

The principle of Just in Time (JIT) is to produce and/or deliver the right quantity of products, of the right quality, within the right time and at the right place in order to increase productivity, efficiency and to decrease costs and wastes associated with overproduction. According to International Journal of Economics, Business and Finance (2013), JIT consists of two main elements which must be integrated together to function in harmony including human resources, planning based on the elimination of wastes.

Between the 1940s and 50s, Taiichi Ohno of Toyota applied the Kanban logic in their Toyota Production System (TPS) to support non-centralized “pull” production control. In the post-depression era of 1970s, Kanban was popularized in the manufacturing industry as a tool for Lean Manufacturing. Of late, many thought-leaders in various industries have found its applicability beyond the manufacturing industry as well.

The mission of JIT is to create and deliver goods just in time to be sold (Daniel et al., 2009). This method includes sub-assemblies just in time to be assembled into finished goods, fabricated parts just in time to go into subassemblies, and purchased materials just in time to be transformed into fabricated parts (Schonberger, 1982). This technique was designed to achieve maximum levels of efficiency and quality production. Before the technique became popular in Western industrialized countries, the Japanese industry used JIT successfully. Taiichi Ohno, credited with creating the JIT system, applied the technique at Toyota in an effort to handle smaller batch sizes and offer a wider variety of car parts that could be used for assemblies (Radziwill, 2010). Prior to JIT, Western

Conclusively, there are two major parts to JIT inventory operations: lowering the ratio between ordering costs and holding costs and shortening lead times. What results is a firm with such high holding costs that ordering very small batches very frequently is the most profitable solution. This eliminates average inventory above the safety stock level. Then, if lead times and lead time variability can be decreased, safety stock can be decreased. The result is inventory coming in as it needs to come in. In other words, it comes in just-in-time.

storage time is needed. Another thing that is needed to properly implement the JIT inventory system is that there should be good coordination between various points of a production process.

A simple example of the kanban system implementation might be a "three-bin system" for the supplied parts (where there is no in-house manufacturing) — one bin on the factory floor (demand point), one bin in the factory store, and one bin at the
