Calculate the yield (number out of step/number into step) of each step. Multiply these together. For example: (# units leaving the process as good parts) / (# units put into the process) = FTY 100 units enter A and 90 leave as good parts. The FTY for process A is 90/100 = 0.9000; 90 units go into B and 80 leave as good parts.
Rolled throughput yield (RTY) [1] in production economics is the probability that a process with more than one step will produce a defect free unit. It is the product of yields for each process step of the entire process. For any process, it is ideal for that process to produce its product without defects and without rework.
Since the production line is directly linked to the output of the machines, it allows for the identifying of the main bottleneck in the manufacturing process. In changing each machines throughput, it will be possible to assess which machine affects the overall output the most, and hence determine the bottleneck in the chain of processes. [6]
Lean manufacturing adopts the just-in-time approach and additionally focuses on reducing cycle, flow, and throughput times by further eliminating activities that do not add any value for the customer. [1] Lean manufacturing also involves people who work outside of the manufacturing process, such as in marketing and customer service.
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).
Throughput is rate at which a product is moved through a production process and is consumed by the end-user, usually measured in the form of sales or use statistics. The goal of most organizations is to minimize the investment in inputs as well as operating expenses while increasing throughput of its production systems.
Process optimization is the discipline of adjusting a process so as to make the best or most effective use of some specified set of parameters without violating some constraint. Common goals are minimizing cost and maximizing throughput and/or efficiency. Process optimization is one of the major quantitative tools in industrial decision making.
A recipe in semiconductor manufacturing is a list of conditions under which a wafer will be processed by a particular machine in a processing step during manufacturing. [158] Process variability is a challenge in semiconductor processing, in which wafers are not processed evenly or the quality or effectiveness of processes carried out on a ...
