كاربرد روش شاينين براي تفكيك فاكتورهاي با اهميت از فاكتورهاي كم اهميت (در بررسي عوامل موثر بر انحراف مقادير اسيديته و pH نوشابه فانا در كارخانه روزنوش كرمانشاه)

Using of shainin Method, to sieve Significant Factors on the Among Insignificant Factors, by the case of Analysis Effective Factors on the Deviation of the Activity and PH of Fana Everage from the Target in the Roz Nosh Kermansha Factory A. R. Momiwan

Recognizing roots of quality problems or keys for improving quality can cause to save resources if significant and effective factors among other insignificant factors can be recognized. After this, those important factors can be focused until goals are achieved. Simple approach can be used continuously. so the grounds for the problems or the keys to improve quality can be found swiftly. In this study, the Shainin as the Design of Experiment (DOE) method is introduced and its four phases is used in Roznosh Kermanshh Company. Although the method is to find significant factors among other factors, all of the factors seem to be important at first and they look as if be effective to solve the problems. The method of sieving those factors used in industrial and servicing sections has been ex pressed and focused in this article. The problems can be identified in a short time by considering two goals simultaneously by means of overall evaluation criteria(OEC), (reducing the deviation of acidity and pH of fana beverages from targets), finding three factors such as pH of refined water, hardness of refined water, brix of fana beverages as significant factors and selling the other factors at levels like those which have minimum of costs Afterward the problems can be solved by concentrating on those important factors. Utilizing this method is simple and everybody can understand scientific approach, even those who may not have powerful statistical knowledge base, but they are engaged with solving the problems or improving the quality of the products or processes. Consequently, this method provides better chance to be compared with another diagnostic quality methods or methods that are used in improving of quality to be used continuously. If this method uses completely not only can find roots of the problems but also can solve the problems.
