Cycle time variation is a metric and philosophy for continuous improvement with the aim of driving down the deviations in the time it takes to produce successive units on a production line. [1] It supports organizations' application of lean manufacturing or lean production by eliminating wasteful expenditure of resources.
A static system does not change in behavior and hence the system stays constant. Finding a bottleneck in a static system is very simple, it is simply the machine or process with the longest constant cycle time. Static systems do not exist in reality as no matter what, there will always be a slight fluctuation in cycle time.
In software engineering, cycle time is a software metric which estimates development speed in software projects. [1] [2] The cycle time measures how long it takes to process a given job - whether it's a client request, an order, or a defined production process stage. The crucial aspect of measuring the cycle time is considering only the active ...
Overall equipment effectiveness [1] (OEE) is a measure of how well a manufacturing operation is utilized (facilities, time and material) compared to its full potential, during the periods when it is scheduled to run. It identifies the percentage of manufacturing time that is truly productive.
Most predetermined motion time systems (MTM and MOST) use time measurement units (TMU) instead of seconds for measuring time. One TMU is defined to be 0.00001 hours, or 0.036 seconds according to MTM100 and 0.0000083 hours, or 0.030 seconds according to BS100. [1] These smaller units allow for more accurate calculations without the use of decimals.
Project production management (PPM) [1] [2] is the application of operations management [2] [3] to the delivery of capital projects. The PPM framework is based on a project as a production system view, [1] [2] [3] in which a project transforms inputs (raw materials, information, labor, plant & machinery) into outputs (goods and services).
Production planning is the future of production. It can help in efficient manufacturing or setting up of a production site by facilitating required needs. [2] A production plan is made periodically for a specific time period, called the planning horizon. It can comprise the following activities:
Backflush accounting is employed where the overall business cycle time is relatively short and inventory levels are low. Backflush accounting is inappropriate when production process is long, and this has been attributed as a major flaw in the design of the concept.
