For more than 30 years, Operations Research teams have shown great interest in the field of healthcare and medical delivery systems and how they function around the globe. In the past few years, the birth rates have been decreasing considerably, especially in developed countries. Along with that, the average global lifespan and longevity has also been rising. Healthcare has obviously proven to be an important aspect in today’s modern and fast paced world, where optimization of scarce resources is the utmost need of the hour. The attention has gradually expanded from merely resource allocation and has moved forward towards strategic planning, in order to include operational issues, namely- resource scheduling and treatment planning.This research paper studies the various application and uses of Operations Research in the area of healthcare delivery systems and their effectiveness. This paper reviews and assesses the major contributions involving contemporary optimisation issues in this particular area of study. The study highlights the research activities in current use, throwing light on the optimisation issues faced by the industry, along with the methods used to find solutions to the optimisation problems and putting them into practice.
