WESTINGHOUSE TEMPO DERECELENDİRME SİSTEMİNE BULANIK MANTIK İLE YENİ BİR YAKLAŞIM

When calculating the production cost of a product, two basic items are taken into consideration. The first is material and second labor cost. Material costs can be calculated very clearly due to lack personal judgment. Because amount used for that product certain. However, calculation may not always as simple precise. produced per unit time directly affects costs. Therefore, calculate correctly, number parts must correctly. At this point, times gain importance. It considered sufficient use values on chronometer when or products. Standard by adding performance tolerance values. Worker vary from person person. Performance varies depending worker ability, effort, consistency working environment. This difference in becomes important manual processes. In automatic processes, especially disassembling assembly processes machines. Tempo rating systems have been proposed standardize performances minimize negative effects differences between individuals. Classical Westinghouse Method one common tempo system. CWM, using skill, environmental conditions, Evaluations these four criteria obtained observing decision-makers. study, fuzzy rule-based method was developed because decision-makers linguistic expressions evaluate performance. Fuzzy applied part company produces cutting machines order prove its validity. As result it determined model more sensitive
