Research on quality cost based on manufacturing process

摘要

Price of Nonconformance (PONC) which produced by scrap, rework and other non-value-added activities in actual manufacturing process bring a large number of loss to the enterprise. In order to quantify the Price of Nonconformance of the manufacturing process, the included projects and the calculation method of scrapped cost, reworked cost and retested cost are proposed. The calculation method can be programmed and implemented by means of C# language in the paper, and the working procedure which the Price of Nonconformance is beyond the standard is analyzed and improved. The results of example analysis and verification show that the calculation method of PONC is an effective way to improve the efficiency of cost management, reduce quality cost, improve product quality and increase the economic efficiency of enterprise.
