Study On Application Of Measurement Systems Analysis In Bus Manufacturer

Measurement system is the package of measurement instruments or measuring tools, standards, operations, methods, fixtures, software, personnel and environment used to quantitatively measure or qualitatively evaluate measured characteristics;Is the whole process to obtain measurement result. Measurement System Analysis can be divided into"Attribute Data"and"Variable Data". Variable Data Measurement System Analysis typically includes"Stability","Repeatability","Reproducibility","Bias"and"Linearity"(Five Natures) analysis and evaluation. The actual operation of the Measurement System Analysis can use them at the same time or optional, identified according to the specific use. This article is based on the brief description of Measurement system and essential components, source of variation, errors and statistical characteristics; focus on detailed presenting and analyzing for MSA. During the 2 cases analysis of incoming inspection and process inspection, implement the evaluation method extensively in Measurement system analysis, and analyze measurement process and measure result systematically and deeply, discover and solve the problem of man-made factors with different people during the measurement procedure, and make the measurement system more powerful and authorized internal and external company .
