Abstract
Companies are facing cut throat competition and are forced to continuously perform better than their competitors. In order to enhance their position in the competitive world, organizations are improving at a faster pace. Industrial organizations must be used to the new ideals, such as innovation. Today, innovative design in the development of new products has become a core value in most companies, while innovation is recognized as the main driving force in the market. This work applies the Russian theory of inventive problem-solving, TRIZ and the fuzzy analytical hierarchy process (FAHP) to design a new shape for machine tools. TRIZ offers several concepts and tools to facilitate concept creation and problem-solving, while FAHP is employed as a decision support tool that can adequately represent qualitative and subjective assessments under the multiple criteria decision-making environment. In the machine tools industry, this is the first study to develop an innovative design under the concept of lean production. We used TRIZ to propose the relevant principles to the shape’s design with the innovative design consideration and also used FAHP to evaluate and select the best feasible alternative from independent factors based on a multiple criteria decision-making environment. To develop a scientific method based on the lean production concept in order to design a new product and improve the old designing process is the contribution of this research.
Highlights
The rapidly changing marketplace leads to companies seeking competitiveness for their products with respect to innovation, higher performance, lower prices and more functionality
Based on the TRIZ-fuzzy analytical hierarchy process (FAHP) synergy, the authors selected the top five criteria from the AHP method as the main objectives and in view of certain subjective and objective aspects to collect the relevant principles from the TRIZ matrix, in order to complete the innovative design of a new shape for machine tools
The hybrid method in our work proposes applying the TRIZ and FAHP based on the lean production concept to design an innovative new shape of machine tools
Summary
The rapidly changing marketplace leads to companies seeking competitiveness for their products with respect to innovation, higher performance, lower prices and more functionality. In this research, we apply the TRIZ and FAHP based on the lean production concept to design an innovative shape for machine tools to meet the requirement of the companies’ competitiveness. Our review of the literature shows that TRIZ and fuzzy, as well as multiple-criteria decision-making (MCDM) are widely used to deal with many issues of enterprise The applications of these tools are briefly discussed in the following. Based on the TRIZ-FAHP synergy, the authors selected the top five criteria (cost of production, cost of development, reliability, costs of marketing, attractiveness) from the AHP method as the main objectives and in view of certain subjective and objective aspects to collect the relevant principles from the TRIZ matrix, in order to complete the innovative design of a new shape for machine tools. The last section highlights the most relevant results of the authors’ work and proposes possible extensions
