Abstract

It is a very importance, both theoretically and practically, to create an indicator system to evaluate the factors affecting construction productivity. This paper uses the expert consultation opinion, the questionnaire survey technique, and the documentary research methods to analyze the and prioritizing influencing factors on construction productivity and evaluate it from the aspects of construction, management, special circumstances, and building the evaluation index system of those factors. Based on the principle of Dempster-Schaffer evidence theory to make group decisions by constructing a comprehensive judgment matrix (to effectively gather the opinions of experts and solve the problem of conflicting opinions, then determine the weights of the indicators through the analytical hierarchy process,. In the end, an index system was obtained to evaluate the factors affecting construction productivity in Iraqi projects, including three first-level indicators/indicators, seven secondary indicators, and 56 third-level indicators, which provides theoretical guidance for project departments in order to study these factors. And work towards developing a system to effectively increase project productivity.
