Interpretive Structural Modeling to Improve Value Engineering Performance in Construction Projects in the Construction Sector of Iran

The purpose of this research is to investigate and classify the relationships between the factors that influence the value engineering use in the Iranian construction industry. A researcher-made questionnaire was used for data collection. The validity and reliability of the questionnaire were evaluated and verified by a team of Iranian construction industry experts. In this research, in addition to value engineering, project risk management requirements and the nature (nature) of the project were used in the conceptual model that improved the performance of value engineering workshops. Interpretive structural modeling method was used to classify the component relationships. Based on the interpretive structural model, the components of expert advice from value engineering team members, "savings rate", "return on investment", "value engineering team leader's satisfaction with the value engineering results" were at the highest level.The purpose of this research is to investigate and classify the relationships between the factors that influence the value engineering use in the Iranian construction industry. Value engineering is a systematic way of achieving project goals. This process is done by evaluating the objectives of the project and how to achieve them. Value engineering strives to improve design while reducing costs and time, increasing the value of the products in question, with the goal of maximizing efficiency and effectiveness in construction and construction projects. So all of these factors will result in us controlling our costs as much as possible.
