Problem: Operations Research (OR) and project management can be thought of as two separate entities that work closely together. Project Management is about motivating and leading a group of people to complete a task. Operations Research is about making better decisions for a business or organization. When combined, project management can be put on a quantitative level. Throughout history, there have been many overlaps between operations research and project management. Most of these relations can be seen through scheduling and network analysis. Tools that project managers use on a day-to-day basis, such as CPM (Critical Path Method) and PERT (Program Evaluation and Review Technique), were derived from operations research (Hillier, 2021). Using algorithms and probability calculations, you can find the longest path through a network of activities and determine the time required to complete a project. Operations research can also be used to help with resource leveling and capacity planning. These are some of the biggest challenges that project managers face. What happens when multiple projects require the same resources? Whether it be people, equipment, or money, sometimes projects can overlap, and it becomes a manager's job to prioritize (Kerzner, 2017). Linear programming, integer programming, and multi-criteria decision models are some of the ways that respond to this in 150 words informal paragraph. Need Assignment Help?
