In this research paper, we aimed at finding out the application of operational research in the field of human resource management. It has always been a known fact that humans are known to make mistakes if work is done without the help of any scientific tool. With detailed research in Human Resource management, it came to our knowledge that the training, selection, recruitment and other processes in various organizations are based on bias and partial views. Also, we realized that average capital that is being invested in the training and development programs is much higher than it should be. This made us want to connect the concept of organizational research in human resource management i.e to maximize the satisfaction with minimum cost. With this motive, we aimed at reading the past articles where we gained information about how organizations are already using Operations Research techniques like Linear Programming and Assignment Problem, for the process of training. Lastly, our research felt complete when we gave real life implications and it was proven to us that Operations Research techniques does help the organizations in making decisions about how they should go about with their HR policies effectively at minimum cost.
