Throughput in business is the rate at which a product is moved through a production process and onward to being consumed by an end-user, usually measured in the form of sales or usage statistics. The goal of most organizations is to minimize the investment in inputs as well as operating expenses while increasing throughput of its production ...
The total first time yield is equal to FTYofA * FTYofB * FTYofC * FTYofD or 0.9000 * 0.8889 * 0.9375 * 0.9333 = 0.7000. You can also get the total process yield for the entire process by simply dividing the number of good units produced by the number going into the start of the process. In this case, 70/100 = 0.70 or 70% yield.
The same period, saw the rise of books and articles with similar concepts and methodologies but with alternative names, including cycle time management, [35] time-based competition, [36] quick-response manufacturing, [37] flow, [38] and pull-based production systems. [39] There is more to just-in-time than its usual manufacturing-centered ...
The machine or process that accumulates the longest queue is usually a bottleneck, however this isn't always the case. Bottlenecks can be found through: identifying the areas where accumulation occurs, evaluating the throughput, assessing whether each machine is being used at full capacity, and finding the machine with the high wait time.

Little's law is widely used in manufacturing to predict lead time based on the production rate and the amount of work-in-process. [15] Software-performance testers have used Little's law to ensure that the observed performance results are not due to bottlenecks imposed by the testing apparatus. [16] [17]
Throughput Accounting also pays particular attention to the concept of 'bottleneck' (referred to as constraint in the Theory of Constraints) in the manufacturing or servicing processes. Throughput Accounting uses three measures of income and expense: The chart illustrates a typical throughput structure of income (sales) and expenses (TVC and OE).
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.
The Shifting Bottleneck Heuristic is a procedure intended to minimize the time it takes to do work, or specifically, the makespan in a job shop.The makespan is defined as the amount of time, from start to finish, to complete a set of multi-machine jobs where machine order is pre-set for each job.
