Optimal Pricing with Speculators and Strategic Consumers
by Yichuan Ding

Xuanming SuIf you are a soccer fan, have you ever experienced the dilemma of affording an unexpectedly expensive ticket to catch a match? If you play electronic games, did you spend hours in the queue for a Nintendo Wii when it was first launched on the market? In Monday's supply chain session, Professor Xuanming Su of Haas Operations and Information Technology Management Group at UC Berkeley concluded that there are three common features of the two phenomena mentioned above: scarcity of supply, a market with alternative channels, and rational speculators.

In the view of Su, the price of scarce goods tends to be volatile because of the existence of speculators, who buy goods purely for resale. Su considered a market composed of firms, speculators, and strategic and nonstrategic buyers, and modeled their behavior in reverse-chronological order based on mild assumptions. In his model, the firm first sells a fixed amount of goods in the primary market to both the strategic customers and speculators; later in the resale market, the speculator and the firm sell the rest tickets to an uncertain number of customers. An analysis of the subgame perfect equilibrium shows that as number of speculators decreases, the primary market price decreases, whereas the resale market increases.

His model also leads to interesting managerial implications. The seller can price speculators out of the market but may choose to underprice and accommodate them. The benefits of accommodating rhe speculator to the firms include an increase of the speculative demand and definite revenue upfront, together with a lower risk that has partly been transferred to speculators. However, the speculator may bring in more competition and reduce the primary market price.

In Su's opinion, the resale mechanisms, the emergence of strategic speculator, and the increased competition from speculators faced by firms are all new elements and deserve further investigation by the supply chain community.
 
Better Smarter Electricity Markets: Efficiently Capturing Wind, Rain and Fire
by Jessica Ng

Richard O'NeillSmart market ideas and technology continue to introduce huge opportunities for improving energy efficiency and cost savings. Imagine your refrigerator embedded with a chip that detects a frequency excursion and responds to that excursion by shutting itself down and starting itself up quickly, thereby allowing the refrigerate to "intelligently" decide when to use energy and at what price. Now imagine that your dishwasher operates in a similar manner - set only to turn on at certain time of night, when energy prices are significantly lower. Picture your hybrid vehicle plugged into a wireless network that logs into an Independent System Operator (ISO) that helps it "decide" when to charge based on the current market prices. The energy-saving and financial impacts of the developing smart market are tremendous.

Richard P. O'Neill, Chief Economic Advisor of the Federal Energy Regulatory Commission, suggested that the name "smart market" should actually be "smarter markets," explaining that current technology is already smart, but there is still a lot of room for improvement. In fact, generators, transmission lines, communication systems, software, and hardware are all going to get smarter. The dynamic energy market proposes the need to develop a model that harmonizes smart market appliances and the demand for a more flexible energy grid. There is a growing need to improve the current ISO Market Design to use smarter hardware to allow for better transmission rates and better approximations to generate better efficiency. In recent years, many ISOs have switched to using mixed integer programming (MIP) as a better tool for modeling start-up and shutdown, nonconvexities, transmission switching, and investment decisions. While improvements to MIP have helped decrease computation time, the algorithms are inflexible to the onset of developing energy sources, such as wind energy. With the need for a more robust large-scale stochastic MIP comes the need for a good paradigm for transmission investment. The increasing focus on software and optimization provides huge possibilities for work in this area, especially for OR/MS scientists.
 
Supply Chain Risk Management
by Yichuan Ding

Christopher TangThe goal of Monday's keynote speech given by Professor Christopher S. Tang of the UCLA Anderson School of Management was to remind the supply chain community of a subject that has not received enough attention: supply chain risk management (SCRM).

SCRM is especially deserving of more attention because in today's world, local incident events can result in global impact more quickly. In addition, a recent survey indicates that company executives are increasingly concerned. However, few concrete efforts have been made toward reducing the risk. Tang argues that the possible reasons include underestimating the risk, ignoring disruptions that rarely occur, and failing to perform risk reduction research.

Next, Tang named several examples to illustrate how SCRM has been overlooked. There are only 785 SCRM research articles from Google, compared with 16,000 supply chain management articles. By reviewing the benchmark papers, Tang concludes that there are three gaps in the current literature of SCRM: (1) no consensus definition of SCRM, (2) a lack of study in response to risks, and (3) a lack of empirical research. He thinks the three gaps, together with the increasing importance of SCRM, make it an exciting area for mutual learning between practitioners and academics.

Tang distributed questionnaires during his speech, asking the audience to share their opinions toward SCRM. He expects to see a change in the attitude of the populous toward SCRM. As he said enthusiastically, "SCRM is a new area that company executives care about, a new area of practice for many consulting firms, and a new area of research that is not well understood!"
 
Decentralized Pricing and Alliances in Revenue Management
by Seda Tepe

Imagine you are booking a ticket for a conference at a city in the northern United States. What you would probably do first is to go online and search for flights from your city to that northern city. Most likely, there will be some dominating airline companies having flights to various cities originating from your city, but finding a direct flight to a selected destination is not always possible. Southwest Airlines, for instance, dominates the south-to-south flights but does not have that many flights to the northern cities. Sometimes, it may not be possible to find a flight just using that specific airline to fly to the destination city, even when you prefer two or more stops. What airline companies do in such cases is collaborating. This session, in a broad view, is about airline collaborations and revenue management.

Xing Hu, the first speaker in this session, gave a talk on airline alliance collaboration and operation. This study focuses on contractual agreements between airlines operating together. Hu proposes methods to split revenue between alliance partners. In this study both the static and dynamic models are considered, and the static transfer prices are proven to be asymptotically optimal.

The second speaker, Sandra Transchel, uses a deterministic linear programming model as an approximation for the network revenue management problem. The transfer prices are found for the centralized system and compared with the decentralized system equilibrium strategies used by the airlines.

Lori Houghtalen concentrates on the revenue sharing problem of carrier alliances. She proposes algorithms to fairly allocate the revenue between alliance partners. When the revenue is shared equally, the overall alliance revenue is higher. However, when the value of a carrier is taken into account, the resources are used more efficiently.

Andrew Lim analyzes the resource allocation problem in a broader sense. He first undertook the pricing and service agents' problems separately---what he calls the "na´ve decentralization" and which was not system optimal. Next, Lim examined the pricing and service agents' problems under collaboration as well as the centralized problem. In the pricing agent's problem, the demand function is known but the cost function is not known necessarily. On the contrary, the service agent does not know the demand function. In this study, centralized optimal is computed under a lack of information sharing.
Edelman Finalists Reprise - I

Decision Engineering at Intel Corporation (The 2009 INFORMS Prize Winner)
Intel's internal Decision Engineering Group is credited with saving the company over $4 billion. This small support group (consisting of 6 to 12 members) has helped to define and successfully improve on the processes of Intel's Enterprise. Using OR/MS principles, the Decision Making Group has helped improve efficiency within Intel's core functions: manufacturing, supply chain, material purchasing, sales and marketing, and product development. In reflecting on the Group's successes, Karl Kempf of the Decision Engineering Group noted several key "lessons learned." He stressed the importance of defining the problem, learning how to use the current approach, and, most importantly, learning the current metrics. After fully understanding the problem and in developing a solution, it is better to work incrementally, building on a simple initial "solution" (which may not be always OR). In developing the actual tool, it is important to work hard on the graphical user interface, because that is the only thing that the customers see. Kempf also emphasized building effective relationships with not only the customer but within the team. These simple tips have proven quite effective in the success of the Decision Engineering Group.

Zara Uses Operations Research to Reenginer Its Global Distribution Process
Jeremie Gallien of MIT's Sloan School of Management and Felipe Caro of UCLA's Anderson School of Management have developed a sophisticated operations research model that has helped significantly improve Zara's sales by 3%-4%, corresponding to approximately $233 million and $353 million in additional revenues for 2007 and 2008, respectively. Zara follows a fast-fashion business model - changing inventory within each of its 1,500 stories twice a week. This model poses a complicated distribution problem. Gallien and Caro replaced Zara's legacy manual process by implementing an OR model that maximizes the total expected sales across the network. The model also incorporates a stochastic store display model that utilizes a "size display policy" that calls for the removal of clothing items that have stocked out of main sizes. Interestingly, this policy has helped mitigate the frustration felt by retailers who have customers that have committed to a garment and cannot find their particular size. This is one of the first applications of OR to the fast-fashion industry and one of the first described implementations of an inventory distribution model that specifically captures the dependencies introduced by a store inventory display model.
 
HP Transforms Product Portfolio Management with Operations Research
by Seda Tepe

2009 Franz Edelman Winners,HPHewlett-Packard (HP), the world's largest technology company, has won the 2009 Franz Edelman Award for its successful product variety management initiatives among six strong finalists. Their project includes the Revenue Coverage Optimization (RCO) software algorithm, developed by HP Labs, and the company's complexity return on investment (ROI) calculators, developed by HP's Strategic Planning and Modeling Team. One of today's keynote sessions was on this innovative project.

HP has a large and diverse product portfolio that needs special care to be successfully managed. The RCO software algorithm that HP OR team developed aids managing the current product portfolio efficiently, and the ROI calculators help HP to assess the effect of offering new products by successfully evaluating the return on investments. The two tools have been used to simplify HP's product offerings for the customers and to advance HP's focus on its key products.

HP implemented the RCO algorithm to rank its personal systems' group product offerings based on the relationship between products and orders. They classified the products into two groups. The "core offering" is composed of the most critical products in each region, which includes approximately 30% of the ranked product portfolio. The rest of the products are classified as "extended offerings." Based on the findings of this project, HP adjusted its service level for the products in these categories. They started to stock the core offering products in higher inventory levels. Moreover, the lead times are shortened for these products. On the other hand, extended offering product inventories are reduced and longer lead times are allowed for these products.

This application led to more than $500 million savings and $180 million ongoing annual savings as well as higher margins and improved service to customers. HP also had significant order fulfillment improvements. In this study, HP used OR as a tool for operational efficiency, risk management, and resource planning. This award-winning project is a fantastic example of OR being the "science of better."
