This document discusses operational research, which is the application of scientific methods to optimize solutions to problems involving system operations. It provides examples of applying operational research to production scheduling, physical distribution, and marketing. The objectives of operational research include minimizing total cost and decision making in complex situations. Some techniques discussed are linear programming, assignment problems, transportation problems, and inventory control models.

2. MEANING OF OPERATIONAL RESEARCH
OPERATIONAL RESEARCH IS THE APPLICATION OF SCIENTIFIC
METHODS, TECHNIQUES AND TOOLS TO PROBLEMS
INVOLVING THE OPERATIONS OF A SYSTEM SO AS TO
PROVIDE THOSE IN CONTROL OF THE SYSTEM WITH
OPTIMUM SOLUTIONS TO THE PROBLEM.

3. APPLICATIONS OF OPERATIONAL RESEARCH
•1.PRODUCTION: SCHEDULING AND SEQUENCING THE
PRODUCTION RUN BY USING LPP.
•2.PHYSICAL DISTRIBUTION: LOCATION AND SIZE OF
WAREHOUSE,DISTRIBUTION CENTERS,RETAIL
OUTLETS,ETC.

4. CONT…..
•3.MARKETING:PRODUCT SELECTION, COMPETITION
ACTIONS,ADVERTISING MEDIA,ETC.

5. MODELS IN OPERATIONAL RESEARCH
• MODEL BY FUNCTIONS
• MODELS BY DEGREE OF ABSTRACTION
• MODELS BY STRUCTURE
• MODELS BY NATURE OF ENVIRONMENT
• MODELS BY THE EXTENT OF GENERALITY
