Conventional computing isn’t enough Combinatorial explosion The distinct nature of operations research Operations Research 12 O.R.: What is It? Operations research (O.R.) is the discipline of applying advanced analytical methods to help make better decisions Operations Research 13 Conventional computing is not enough Cannot enumerate alternatives Combinatorial explosion of viable options “Few” alternatives Operations Research Never got outside the box 14 Combinatorial explosion Example 1 Problem: Find shortest path through 10 points – Assume a super-powered computer analyzes, quantifies, and compares a million alternatives every second – Answer is found in less than one second Now find the shortest path through 20 points – Same computer would take over 39,000 years to solve Operations Research 15 Combinatorial explosion Example 2 Construct a 5 stock portfolio out of 100 possible stocks – Evaluate for risk and return using same computer as Example 1 – Answer found in 1.25 minutes Now diversify to 9 stocks – Answer found in 220 days Now diversify to 10 stocks – Answer found in 5.5 years Operations Research 16 Distinct nature of O.R. Applies leading-edge analysis Can find the best among many choices, in reasonable time Can consider and balance multiple objectives Can help measure, control, and reduce risk Operations Research 17 O.R. success stories Representative cases from the annual INFORMS Edelman Competition 2002: Continental Airlines Survives 9/11 2001: Merrill Lynch Integrated Choice 2001: NBC Optimizes Ad Sales 2000: Ford Motor Prototype Vehicle Testing 1996: Procter & Gamble Supply Chain 1991: American Airlines Revolutionizes Pricing Operations Research 18 Case 1: Continental Airlines Survives 9/11 The problem – Long before September 11, 2001, Continental asked how it could plan recovery from potential disasters such as massive weather delays Operations Research 19 Continental Airlines (con’t) Strategic objectives and requirements – – – – – 1,400 daily flights 5,000 pilots 9,000 flight attendants FAA regulations Union contracts Operations Research 20 Continental Airlines (con’t) The O.R. solution – Working together with an operations research consulting firm – Used an optimization model to generate optimal assignments of pilots and crews following a major disruption of service – Solution offers a system-wide view of the disrupted flight schedule and all available crew information Operations Research 21 Continental Airlines (con’t) The value – Millions of dollars and thousands of hours saved for the airline and its passengers with each major disruption – After 9/11, Continental was the first airline to resume normal operations Operations Research 22 Case 2: Merrill Lynch Integrated Choice The problem – Deal with the competitive threat of online investment firms – Without alienating financial advisors, undervaluing services, or incurring substantial revenue risk Operations Research 23 Merrill Lynch (con’t) Objectives and requirements – Evaluate new products and pricing options – Evaluate options of online vs. traditional advisor-based services Operations Research 24 Merrill Lynch (con’t) The solution – Merrill Lynch’s O.R. group simulated clientchoice behavior, allowing it to: » Evaluate the total revenue at risk » Assess the impact of various pricing schedules » Analyze the bottom-line impact of introducing different online and offline investment choices Operations Research 25 Merrill Lynch (con’t) The value – Introduced two new products garnering $83 billion ($22 billion in new assets) and produced $80 million in incremental revenue – Helped management identify and mitigate revenue risk of as much as $1 billion – Reassured financial advisors Operations Research 26 Case 3: NBC Optimizes Ad Sales The problem – NBC sales staff had to manually develop sales plans for advertisers, a long and laborious process to balance the needs of NBC and its clients – The company also sought to improve the pricing of its ad slots as a way of boosting revenue Operations Research 27 NBC (con’t) Objectives and requirements – Complete intricate sales plans – Reduce labor cost – Maximize income Operations Research 28 NBC (con’t) The O.R. solution – Used optimization models to reduce labor time and – Used revenue management to improve pricing of its ad spots, which were viewed as a perishable commodity Operations Research 29 NBC (con’t) The value – In their first four years, the systems » increased revenues by over $200 million » improved sales-force productivity » improved customer satisfaction Operations Research 30 Case 4: Ford Motor Prototype Vehicle Testing The problem – Developing prototypes for new cars and modified products is enormously expensive – Sought to reduce costs on these unique, firstof-their-kind creations Operations Research 31 Ford (con’t) Objectives and requirements – Needed to verify the designs of its vehicles and perform all necessary tests – Prototypes often sit idle awaiting various tests, so increasing their usage would offer clear benefits Operations Research 32 Ford (con’t) The solution – Ford and an O.R. consulting firm developed a Prototype Optimization Model (POM) to reduce the number of prototype vehicles – The model determined an optimal set of vehicles that can be shared and used to satisfy all testing needs Operations Research 33 Ford (con’t) The value – Ford reduced annual prototype costs by $250 million Operations Research 34 Case 5: Procter & Gamble Supply Chain The problem – To ensure smart growth, P&G needed to » » » » improve its supply chain streamline work processes drive out non-value-added costs eliminate duplication Operations Research 35 Procter & Gamble (con’t) Objectives and requirements – P&G recognized that there were potentially millions of feasible options for its 30 product strategy teams to consider – Executives needed sound analytical support to realize P&G’s goal within the tight, one-year deadline Operations Research 36 Procter & Gamble (con’t) The solution – The P&G O.R. department and an O.R. consulting team created decision-making models and software. – Followed a modeling strategy of solving two easier-to-handle sub-problems: » Distribution/location » Product sourcing Operations Research 37 Procter & Gamble (con’t) The value – The overall effort saved $200 million a year before tax – Allowed P&G to write off $1 billion in assets and transition costs Operations Research 38 Case 6: American Airlines Revolutionizes Pricing The problem – To compete effectively in a fierce market, the company needed to “sell the right seats to the right customers at the right prices” Operations Research 39 American Airlines (con’t) Objectives and requirements – Airline seats are a perishable commodity whose value varies » At times of scarcity they’re worth a premium » After flight departs, they’re worthless – The new system had to develop an approach to pricing while creating software that could accommodate millions of bookings, cancellations, and corrections Operations Research 40 American Airlines (con’t) The solution – The team developed yield management (a.k.a. revenue management) and dynamic pricing – The model broke down the problem into three subproblems: » Overbooking » Discount allocation » Traffic management – The forecasting and optimization models were embedded in a large revenue management system that interfaces with the reservation system Operations Research 41 American Airlines (con’t) The value – In 1991, American Airlines estimated a benefit of $1.4 billion over the previous three years – Since then, yield management has been adopted by other airlines, hotels, car rentals, and cruises—resulting in billions of dollars in added profits Operations Research 42 Some important points Differences between O.R. and IT Keys to success Conclusion Operations Research 43 Differences between O.R. and IT IT – Focuses on data as a corporate resource – Stores, retrieves, formats, displays data – Understands business processes and transactions Operations Research O.R. – Helps management select the best decision or set of decisions – Applies analysis to convert data into useful information – Works with management to help gain the deepest insights from analytical results – Is typically embedded in an information system to provide recommended decisions or actions 44 Keys to success Focuses on business impact and implementation Improves decision processes while reducing risk Helps operations become
