Abstract :

Flawless product production is one of the strategic goals of any organization. However, achieving this goal is not possible without eliminating waste. Lean production method is used as a way to reduce waste. The main philosophy of lean production in one sentence can be "the elimination of any activity and process that does not create value." Such activities are called wastage. This is achieved by techniques called lean manufacturing tools. The lean literature offers a variety of methods for identifying and disposing of waste, but many organizations still face several difficulties in implementing lean manufacturing systems. This study tries to use Triz as a powerful, efficient and structured tool that has opened a different perspective in the field of defining and solving problems facing human beings, to reduce waste in the driving force industrial company and use its problem-solving tools as solutions. Introduce effective in order to achieve pure principles in this organization. For this purpose, Topsis technique was used as one of the most efficient MADM methods and more efficient Triz tools in achieving pure principles were identified and prioritized based on effectiveness. According to the ranking results of Triz tools, the splicing tool is in the first priority, which is an analytical tool that plays a key role in structuring the problem and analyzing the situation, and directly eliminates the loss and creation of value.
