Just-in-Time History

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

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

In order to speed up the process, Toyota could give a chance to the process manager to make changes to the attachment methods and quality test them. If successful, this could increase the daily yield of parts per day, helping towards the goal.

This problem was addressed in the first assembly line by creating the flow of the conveyor belt. This change alone approximately shaved off about half a minute of production time in each section of the car. Although, stations were already being used in assembling a car, the conveyor belt aided in not only putting them closer together but also giving the assembly a smoother finish. An automobile is constructed from the ground up, meaning the frame or chassis is made first, placed on the conveyor belt and moved down the line to be assembled. Although, this assembly line system seemed simple it was a huge transition to go from complete manpower to machine power.

Eliyahu M Goldratt purpose of writing this book is to introduce individuals to how to manage and measure effectively. Goldratt illustrates how the accounting cost figures and productivity per machine can actually be problematic for it misleads individuals into thinking they’re achieving the goal. Rather all attention should be focused on strategy planning and managing the bottlenecks because they are the true driving metric of production. One major takeaway message from this novel is that there is always room for improvement. This philosophy of ongoing improvement originated in a Toyotas production system and is better know as the Kaizen theory. The Novel, stresses the Kaizen theory, which starts with an indication, then an in-depth analysis, followed by a diagnosis, eventually arrive ate a hypothesis and ending with

People ask, 'can anything stop Toyota?' but quality you can ultimately match, and costs you can match. Design, you can't. There's no reason why we can't match the manufacturing cost and quality of the best if we're focused on doing what needs to be done (Buss, 2005). We have to figure out how to share it - how to capture what's going on that is right and move it around to all the other plants, benchmarking and sharing stuff off the shelf (Buss, 2005). One thing many automakers have accomplished over the years is empowering the employees all the way down the chain.

These three factors, simplicity, interchangeability, and ease of attachment assisted Ford in his competition. In addition to mitigating costs, he also removed the expert fitters which they had always been a key factor for every assembler’s

Toyota production system is made different varieties of vehicles on the same assembly line. Toyota discover a production system which focus on eliminating waste of time and raw materials from every step of production process to get higher quality, greater productivity, improved customer responsiveness and better utilization of equipment and

Toyota uses processes that are both implicit and explicit. Toyota’s operations are enormously flexible and responsive to customer demand. According to ASHP Foundation (2007). Many credit Toyota’s success to aspects of the Toyota Production System, established by Taïchi Ohno and Shigeo Shingo from the late 1950s through 1970 (when it gained the name). It includes aspects of Jidoka, just-in-time production, and kaizen, reducing both inventories and defects. The system is used worldwide, but is only one of the reasons for Toyota’s success. The very rigidity of the operations that makes the flexibility possible. That’s because the company’s operations can be seen as a continuous series of controlled tests.

The JIT (see Womack et al., 1991) concept and approach renovated vehicle production at Toyota. As a result of worldwide favorable

Lean manufacturing originated long before Toyota and Ford, however the thought that it originated with Toyota is flattering since they are the ones who perfected it. By creating the Toyota Production System (TPS), Toyota found a better way to produce large quantities of product efficiently with eliminating the waste factor and while cutting down cost. Taiichi Ohno a former Toyota vice president promoted the idea of JIT (Just-in-Time) which means “producing the necessary units in the necessary quantities at the necessary time.” (Monden) Which leads to Toyota’s ultimate goal in the TPS is to improve productivity for better return in investment. To have continuous flow in a production system Toyota sought out to achieve the concept of JIT and autonomation . Since the TPS is what creates the parts who monitors the JIT system? The kanban system which is an informational system that controls quantities being produce in each process. As the discussion carries on throughout this paper about Toyota and their use of the kanban system the topic

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.

Therefore, Toyota has developed its own software that connects dealers to factories and factories to suppliers. The integration of the value chain creates visibility for all members of Toyota 's supply chain. When a request from a dealer is received by Toyota their "software is able to figure out the availability of parts nearby, the time to resequence the assembly line and whether the change would unbalance the line by scheduling, for example, too many models loaded with time-consuming options one right after the other" (Fahey, 2004).

Toyota changed their factory layout. Previously all machines of the same type, e.g. presses, were together in the same area of the factory. This meant that items had to be transported back and forth as they needed processing on different machines. To eliminate this transportation different machines were clustered together so items could move smoothly from one machine to another as they were processed. This meant that workers had to become skilled on more than one machine - previously workers were skilled at operating just one type of machine. Although this initially met resistance from the workforce it was eventually

Since the dawn of human existence evolution in all sectors of society has occurred due to Economic factors. This has mainly happened due to the fact that all technological achievements have occurred in favor of money.
