Definition of OR

–T.L. Saaty:
A collection of tools and techniques which provide bad answers to problems ………………………….…………….. which otherwise have ………………… worse answers BITS Pilani, Pilani Campus

Evolution of OR
• History –U.S. Navy –Naval Research Forum –P.M.S. Blackett –Naval Research Logistics • Need – civilian applications • OR – Blend of art and science BITS Pilani, Pilani Campus

Application Areas
• • • • • • • • Allocation (product-mix) Scheduling & Sequencing Routing Replacement Inventory Queueing Search Competitive BITS Pilani, Pilani Campus

Application …(contd.)
• Allocation: ….involves allocation of resources to activities in such a way that some measure of performance is optimized Ex: Diet mix problems Assignment problems BITS Pilani, Pilani Campus

Application …(contd.)
• Sequencing: … deciding the precedence relations among various activities that are to be performed so as to optimize time/cost/… factor(s) – Building of Health Care Centres

• Routing: …finding the optimal route from an origin to a destination among possible routes – Ex. Managing Network of Health Care Centres BITS Pilani, Pilani Campus

Application …(contd.)
• Replacement problems: … occur when one must decide the optimal (proper ?) time to replace an equipment that deteriorates or fails… Ex: When should an equipment to be replaced with a new one? BITS Pilani, Pilani Campus
