Analysis of Traditional and Fuzzy Quality Control Charts to Improve Short-Run Production in the Manufacturing Industry
نویسندگان
چکیده
Quality control charts are limited to controlling one characteristic of a production process, and it needs large amount data determine limits the process. Another limitation traditional chart is that doesn’t deal with vague environment. The fuzzy work uncertainty exists in data. Also, investigate random variations found between samples. In modern industries, productivity often different designs small volume depends on market need for demand (short-run production) implemented same type machines units. such cases, difficult operations carried out machines. This aims compare short-run production. case, collected were processed using (Minitab 21) software. It was more flexible accurate determining machine under study. deviation from nominal showed false alarm observation (15) as out-of-control, while (DNOM) these observations control. standard process dropped (σ =0.209041) =0.204401) after chart.

Fuzzy Short-Run Control Charts
Statistical control charts are useful tools in monitoring the state of a manufacturing process. Control charts are used to plot process data and compare it to the limits set for the process. Points plotting outside these limits indicate an out-of-control condition. Standard control charting procedures, however, are limited in that they cannot take into account the case when data is of a fuzzy n...

Nonparametric control charts are presented in order to figure out the problem of detecting changes in the process median (or mean), or changes in the variability process where there is limited knowledge regarding the underlying process. When observations are reported imprecise, then it is impossible to use classical nonparametric control charts. This paper is devoted to the problem of c...
متن کاملFUZZY CONTROL CHARTS FOR VARIABLE AND ATTRIBUTE QUALITY CHARACTERISTICS
This paper addresses the design of control charts for both variable ( x chart) andattribute (u and c charts) quality characteristics, when there is uncertainty about the processparameters or sample data. Derived control charts are more flexible than the strict crisp case, dueto the ability of encompassing the effects of vagueness in form of the degree of expert’spresumption. We extend the use o...
