Analytical Review Of The Value Engineering Methodologies And Selecting Superior Methodology Based On Topsis Multi-Criteria Decision

Abstract

Value engineering is one of the management tools which has been used in recent decades and is defined as a set of systematic techniques, based on creativity and teamwork to solve problems that are applied to reduce costs and performance improvements and quality of the project, products and processes. The application of this tool is preferable to manage the minds of experts in order to create Brainstorm and valuable ideas and provides creativity in order to modify the system. Generally, value engineering includes ancillary advantages such as the creation of synergy in the organization, improve communication between design factors, take advantage of applicable ideas in similar projects, increase teamwork spirit within the organization, trading beneficial factors functionalist design thinking and promote creative thinking and deconstructing in addition to its original benefits including improving design quality and reduce costs. Although the engineering value are provided about fifty years ago in developed countries, to analyze the performance of a product or service and provide an acceptable option with the lowest cost and used in various projects, but in our country only in recent years the importance of this subject is addressed and the first steps have been taken for its application. Also noteworthy based on studies in this context, it can be concluded that according to the modern methods of value engineering in comparison with previous methods, value engineering positions at top management levels are placed and encircles all a system of senior executives and clerks. In this study at first, value engineering definition is reviewed from the perspective of institution and various researchers and finally by adopting a comparative evaluation between different methodologies based on expert opinion and industry experts, the most appropriate methodology will be introduced to use in projects within the country through applying multi-criteria decision making on TOPSIS method.
