A study of effective factors on being a lean organization (Case study)

Lean production is a system that challenges mass production system, and in a short time it has trailed great benefits. This study by examining this production system in one of the big production company in the country i.e.soufian cement co. tries to evaluate the extent of different production indices being lean in this industry. Regarding this , the rapid plant assessment process of Eugene Goodson, the professor and researcher at Michigan university, was chosen as a core pattern. it was studied and criticized, weak points were deleted, the necessary expansion and development were implemented. The essential factors and related indices were identified. Through the proportional assessment questionnaire their proportion with cement industry was measured. After eliminating the less proportional indices and the use of analytical hierarchy process (AHP), the coefficient importance of variables and related indices with the help of experts, were calculated. Finally this coefficient importance and the points that were given to the conditions of indices by experts the extent of essential variables being lean and the soufian cement company with the use of DOA method were identified. The priority attention to the improvement of variables and creating the improvement cycle have been suggested, to the cowpanys management.
