Takt time, or simply takt, is a manufacturing term to describe the required product assembly duration that is needed to match the demand.Often confused with cycle time, takt time is a tool used to design work and it measures the average time interval between the start of production of one unit and the start of production of the next unit when items are produced sequentially.
Sample Production Parts A sample from the same lot of initial production run. The PPAP package usually shows a picture of the sample and where it is kept (customer or supplier). Master Sample A sample signed off by customer and supplier, that usually is used to train operators on subjective inspections such as visual or for noise. Checking Aids
A given Work Center is scheduled to run for an 8-hour (480-minute) shift with a 30-minute scheduled break. Operating Time = 450 Min Scheduled – 60 Min Unscheduled Downtime = 390 Minutes The Standard Rate for the part being produced is 40 Units/Hour or 1.5 Minutes/Unit The Work Center produces 242 Total Units during the shift.
Low rate initial production (LRIP) is a term commonly used in military weapons projects and programs to designate the phase of initial, small-quantity production. [1] The term is also applied in fields other than weapons production, most commonly in non-weapon military equipment programs.
Demand for items from inventory is continuous and at a constant rate; Production runs to replenish inventory are made at regular intervals; During a production run, the production of items is continuous and at a constant rate; Production set-up/ordering cost is fixed (independent of quantity produced) The lead time is fixed
Lean manufacturing is a method of manufacturing goods aimed primarily at reducing times within the production system as well as response times from suppliers and customers.It is closely related to another concept called just-in-time manufacturing (JIT manufacturing in short).
Ready to begin low rate production. Detailed system design essentially complete and sufficiently stable to enter low rate production. All materials are available to meet planned low rate production schedule. Manufacturing and quality processes and procedures proven in a pilot line environment, under control and ready for low rate production.
In the long run, all factors of production are variable and subject to change in response to a given increase in production scale. In other words, returns to scale analysis is a long-term theory because a company can only change the scale of production in the long run by changing factors of production, such as building new facilities, investing ...
