This study presents an algorithm to optimally adjust the input parameters of the wirecut to align its output with the customer’s expectations. For this, AHP and QFD are used to identify and prioritize customer needs in the form of a desirability function. Then, using the Taguchi method, variance analysis, and regression, a fitness function is prepared and optimized by the multi-objective genetic algorithm. Through a case study, the proposed method is validated in terms of flexibility, simplicity, speed, cost-effectiveness, and updateability. Also, customer satisfaction is calculated for two groups of 45 people, with and without using the proposed method. The growth of the customer satisfaction index (CSAT) from 57.6 to 70.3, and the customer satisfaction score from 30.2 to 54.2, show the positive performance of the method. This converts regular customers into loyal ones. It also makes them encourages others to use the mentioned services and widen the customer network. It is clearly seen in the growth of the net promoter score from 6.67 to 31.11. All in all, it can be said that this algorithm helps the survival, profitability, and expansion of an industrial organization.
The need for revision, the difficulty of visualization, and the impossibility of using 2D drawings as the input of manufacturing machines make us attempt to acquire a 3D model from 2D engineering drawings. However, the main problem in this process is that we encounter many potential uncertainties. In this paper, to overcome this problem, we used the fuzzy logic as a mathematical tool based on knowledge of an expert. One of the most outstanding advantages of using the fuzzy logic is that uncertainty in related equivalent elements in different orthographic views is reduced. Another important feature of this method is that only two orthographic views are used to reconstruct the 3D model, while in previous methods, three orthographic views were used. Reducing the limitations of reconstruction of 3D models will result lower cost because of simulation of production processes on a 3D model and direct connection to CAD/CAM Systems, conservation of natural resources and more security for documents by maintaining drawings in computer memory, improved education quality and increased health level as a result of better visualization using 3D Object which will ultimately lead to sustainable development.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
