Operational research (O.R.) emerged during World War II, initially in military contexts, and evolved into a distinct discipline focused on quantitative decision-making in management. It serves as a valuable tool for optimizing resource allocation, minimizing costs, and improving decision-making processes. However, O.R. faces limitations such as high costs, neglecting intangible factors, and potential biases that affect its reliability.

2. The Development… A historical Outlook
 Development in Military context during world war second
 Especially in England by British Forces
 Drawn personnel from multiple fields
 Same repealed in USA, Canada
 Evolved as a separate science & discipline
 After end of Second world war, O.R started seeking military teams
attention towards industries for solving complex managerial
problems.

3. Operational research is a
Scientific method of providing executive departments with a
quantitative basis for decisions regarding the operations under
their control.

 Solution of various business problems
 Enables proper deployment of resources
 Minimizing waiting & servicing cost
 Enable management to decide when to buy & how much
 Assist in choosing an optimum strategy
 Great help in optimum resources
 Facilitates in decision making process
 Integrate business systems

5. Limitations
 Inherent limitation concerning mathematical expressions
 High cost involved
 O.R does not take into consideration the intangible factors
