摘要：Previous research indicates the positive effects of the integrated lean manufacturing on the performance of factories as well as awareness. This paper represents the definition of lean manufacturing together with the lean manufacturing t ools, improvements through these tools such as how to make the production with the minimum level of waste products, and showing how to get a high productivity in a short time while production is working. Three different factories are selected from three di fferent Middle East countries and are given a questionnaire in order to evaluate the awareness and performance of the Petrochemical Companies in the Middle East countries. Based on the obtained feedback, information on how the level of knowledge about lean manufacturing is, and whether those companies are using lean manufacturing tools in their production systems are gained. The analytical hierarchy process (AHP) method is one of the briefly used sup - criteria decision - making methods. It includes the princip les of separation, pairwise comparisons, and significance vectors and combination. Therefore the AHP method is used to appraise the questionnaire's values to judge which tools are more important and useful for the production systems
