| Popis: | 94 Ever since that time six the Sigma systems achieved success in the MOTORA and the GE electricity of operation, take becoming the improvement product quality most as a valid technique, domestic and international each big manufacturer or on one''s own initiative introduce or the Mei is at the customer of request and passive ducting it may be said unprecedented upsurge, but six Sigma system by statistics technique and project management style of close combine an usage don''t found, the former SPC, SPCDA or DOE all can have similar effect, fresh and few can hear as six the successful results of the Sigma systems, so in spite of is promote SPC, SPCDA, DOE, ISO 9000 or 6 Sigma system, all reply its result to measure its devotion and produce in appropriate way of results, thus then can install and apply in the resource up get better combination. Theories and technique of quality cost all right it has a year, but most of the enterprise still pursues smallest turning of the finance cost fresh and few in point of the rationalization of quality cost, in the ISO 9004:20008.2.1.3 inner part auditors and 8.1.2.4 finance measurement etc. minor point of conduct particularly points out a suggestion to list as the whole results of the management system of the valuation quality by quality cost, even is six Sigma systems also shouldn''t the exception manages at the quality of scope, in other words measure an enterprise to duct into six Sigma systems by quality cost method put into and produce of the results is reasonable and viable. The energy price upsurges in recent years, the enterprise operating cost goes up to compress profit space, make the enterprise pay attention to various the ducting which manage a technique and tool to insure by controling production cost profits more, but how evaluate these management technique and tool team to conduct results whether have the positive benefit then has worry in uncertainty more. This research by is a case study of high-tech industry to the home, inquire into an individual case company to duct into six Sigma systems in front and back a set quality cost a geologic change to move, and with the actual quality cost data in individual case company martial year carry on quality cost analysis.Inquire into an individual case company to duct into initial stage in six Sigma systems, variety trend and connection of various quality cost.And inquire into the quality cost amount of amount of money to turn index sign, measure the consistency of index sign with the traditional quality level of the individual case company to identify the effect of six Sigma systems. Inquire into through the quality cost analysis and the reason, the result for being got as follows: 1.Various unit quality cost duct into a period in six Sigma systems and present to prevent cost from going up of trend, show quality an improvement the promoting of activity needed to cost higher expenses in the early years and particularly trained budget. 2. After the ducting of six Sigma systems, the individual case company always has already carried on of the project manifestation can reduce an abnormality to shut down time. 3. Six ducting cost variety of the initial stage, inner part and failure of the Sigma system aren''t notable. 4.If can make progress to DFSS from the DMAIC be contribute to preventing latent failure of possibility, can be accurate more to control the reason and control measure of manufacturing process fluctuation. |
