Study On The Relationship Between Sampling Plan And Quality Cost For Electronic Products Of IPC Company

With modern manufacturing technology development and competitionintensifies between enterprises，the survival and development of manufactur-ing enterprise faced more severe challenges; as for electronic productsmanufacturing enterprises,In addition to attention to production efficiency,the more importance is that how to draw up the effective sampling planand reasonable quality cost improve the capability of process and preventdefective products from flowing to customer site,so as to assure the qualityof products to meet customer requirement, which contribute to improveingthe economic benefit of enterprises and competitiveness; so the effectiveinspection sampling plan and reasonable quality cost drew up that becomeone of the important ways for the enterprise products to receive customersthe high recognized and improve the company’s competitivness。The thesis regards IPC electronic product company as analysis object;a mathematical decision model for RTY(rolled through out yield) of mini--mum quality cost is established according to quality cost theory knowledgeand the method of derivative extreme value, based on the analysis of theexisting RTY of the production enterprises of and quality cost structure ofsampling plan; which combine to customer quality goal and binominaldistribution theory knowledge in applied probability and statistics to draw up the reasonable and effective sampling plan and AQL (acceptance qualitylimited)value; then establish the decision model of the relation betweensampling plan and quality cost for electronic product company according tothe method for analysis of regression equation，which not only consideredelectronic product quality costs and customer quality objects to solve theissues of quality management,moreover,we can infer the corresponding costof quality according to the customers with different sampling plan of AQL,which provide support for manufacturing enterprises to make decision ofquality cost; Finally, the research conclusion between different samplingplan and quality cost is applied and disseminated at internal company andsimilar electronic product company, which provide basis for quality costdecision, it has realistic significance for manufacturing company to improvethe quality competitiveness of the enterprise and customer satisfactorydegree。...
