Toyota Production system : Determine Daily Production Order

For example there is a production line is expected to produce 10,000 cars type A in 10 working days, 8 hours each, within a month. 10,000 cars type A consists of the 5,000 cars, 2,500 hardtop, and 2,500 wagons. If these values are divided by 20 working days, obtained 250 sedan, 125 hardtop, and 125 wagons per day. This is pelancaran production in terms of average daily amount of each type of cars manufactured, so is great for people wanting to change their cars for a new one, since getting rid of a car is not that difficult with services as Scrap My Car Montreal online. In a turn (shift) operations during the eight-hour (480 minutes), have produced 500 units. Therefore, the unit cycle time, or mean time needed to produce one vehicle of any kind, is 0.96 minutes (480/500) or about 57.5 seconds. The right mix or production sequence can be determined by comparing the actual cycle time to produce a particular model of car type A. For example, the maximum time to produce a sedan type A is

TPS principle: Self Adjust to a Changing Number of Production Change

Let us consider the adjustment of production by using Kanban. Suppose a machine fabrication process should produce 100 engines per day. The next process, with Kanban-making, asking for five machines per one lot. Lot-lot was then drawn 20 times per day, in order to reach exactly 100 the number of machines produced each day. With a production plan like this, if there is a need to reduce all of the production process by 10 percent as the adjustment procedure, the final process in this example should take the machine 18 times per day. Then, because the machine only produces 90 units a day, the time left for the 10 units will be saved by stopping production of this process. On the other hand, if there is a need to increase total production by 10 percent, the final process should take the machine 22 times per day with Kanban it.Then the previous process must produce 110 units, an additional 10 units could be covered through overtime.
