Operations Research is an analytical tool to support complex problem-solving and decision-making. The success of OR methods is that it is a systematic approach that provides a framework for constructing conceptual and mathematical models, analyzing alternatives with respect to specified measurable parameters, and finding out the best solutions among all alternatives under a constraint environment. OR contributes to improve project management by applying different techniques such as Critical Path Methods (CPM) and Project Evaluation Review Technique (PERT), reduce logistics cost and quality delivery through network optimization, traffic simulations, decision theory, game bottleneck elimination (game theory), linear programming, transportation problems, etc. In this research paper, we are mainly focused on the practical application of Operations Research in the construction industry to optimize cost for quality and timely delivery with minimum wastages.
