Most of the organizations employ lean production techniques in a separate manner for eliminating the waste. However, in some cases, in spite of spending huge amount of costs for implementation of these techniques, they could not reach the planned benefits. Therefore, creating a mechanism in order to inform managers regarding the benefits of waste elimination prior to technique execution is one of the vital issues in implementation of these techniques. In this case study, lean production tools have been introduced in a systematic manner by applying value stream mapping, which is one of the main lean production tools in identifying wastes and improvement of opportunities. Furthermore, in order to analyze the results of deploying the above techniques, two simulated models for the current and improved situations have been developed. Finally, by executing the simulated models, two systems have been compared on the basis of key measures, which are lead time production, inventory in process, and unnecessary transportation. The results showed a significant decrease in waste.
