Developed as a companion to the Red Brand Canners (RBC) case, the starting point in this case is the improvement in performance resulting from the optimization approach in the original case. However, RBC’s vice president of operations is concerned about the quality and quantity mix of the most recent tomato crop received from Greenfield Farms (GF). RBC’s preferred quality and quantity mixes differ significantly from the current harvest. To RBC, the issue is how to motivate the supplier to produce a crop more in line with RBC’s needs. Initially, both firms in the B2B section of the supply chain try to find a combination that would be mutually beneficial — an attempt that fails because of conflicts of interest. RBC’s objective might be accomplished by taking a supply chain approach and modifying the delivery contract by an appropriate pricing scheme. The task is to identify and calibrate a pricing scheme that will realize the supply chain’s maximum performance and lead to a stable win-win solution. The derivation of the supply chain optimal prices is carried out by developing and solving a linear optimization model.

The City of London was expropriating a portion of Springbank Drive as part of a project to widen the road between Wharncliffe Road and Wonderland Road. The owner of Canning Consultants Inc. was retained by the city to assess the resultant property value loss for the affected residents. The consultant had assembled a database of residential sales along with various property attributes, and had to determine how to proceed in calculating appropriate compensation for the taking. This case is appropriate in a module on multiple linear regression models.

The president of Oakville Hydro Energy services needed to make a decision on the installation of an electricity-generating engine at the regional municipal Wastewater Treatment Plant in Burlington, Ontario. This engine installation was in support of the production of green power, and the Ontario Power Authority (OPA) had introduced a feed-in tariff that paid a premium for the generation of this type of green power. One of three specific engines would be purchased and installed to generate electricity from the combustible gases produced during wastewater treatment. The president had to decide which engine generator would produce the most favourable output and the best return for Oakville Hydro and the municipality. The president also needed to decide whether or not to integrate the existing on-site gas storage tank into the controls of the generator system.

A research institute has a concern with the reliability requirements of a military vehicle. Reliability is the probability that a system will accomplish its designated mission in a satisfactory manner or in more specific terms, the probability that it will perform in a satisfactory manner for a given period when used under specified operating conditions. Reliability of a weapon system is often expressed in terms of mean time between failure (MTBF). Two military vehicles were tested to obtain reliability life data for reliability evaluation. The objective of this case is to introduce reliability concept, MTBF, life data analysis and objective procedure for a decision making.

Yangarra Resources Limited, a Calgary-based junior oil and gas company, had several properties throughout Alberta comprising both solely controlled and joint ventures. The president and chief executive officer (CEO) was involved in the construction of a well on the Ferrier property — a joint venture between three companies, each holding roughly one-third of the stake. As part of the joint venture, Yangarra had signed an agreement that committed Yangarra to cover all expenses proportional to its working stake of 31.875 per cent. The well had been drilled at a higher cost than expected, with many charges not yet recorded or incurred. As a result of the cost overruns, Yangarra had been asked to provide more funding to the project. In deciding whether to commit additional resources to the Ferrier well, the CEO had to consider several factors including an existing gross overriding royalty revenue (GORR) agreement, uncertainty in estimating the recoverable quantity of oil, crown royalties, and a current legal dispute.

Schering Plough is a large pharmaceutical company with over 22,000 employees worldwide, and over $6.8 billion in sales worldwide. The company is considering two options to replace its flagship drug, Claritin (an antihistamine), as Claritin's patent is soon to expire. One drug is targeted toward nasal congestion, the other towards asthma; however, each drug is at a different stage in the development process, one has greater market potential but was still in its early development stage, the other drug could be launched within the year but would appeal to a much smaller market. The company must decide which drug to pursue or whether to focus on both drugs or neither. The case allows students to do a traditional NPV analysis and decision analysis and the use of simulation.

Mahindra & Mahindra Ltd., a US$15.4 billion company in 2012, has been the number one tractor manufacturer in India for the last 30 years. The agriculture tractor sale market in India is seasonal in nature and growing. To meet demand, the company has four manufacturing plants and 26 sales offices across the country; their main job is to coordinate supplies between its 800 dealers and the company. The sales offices provide a rolling tractor demand forecast for the current month plus two months in the future; it is used to determine the number and models of tractors to manufacture and to enable placing parts supply orders in advance. The deputy general manager of sales in the company’s Farm Division has been receiving an increasing number of complaints from irate dealers about the irregular and short supply of tractors from the company’s stockyards. This has created stress and low dealer satisfaction. The deputy general manager has decided to improve the demand forecasting of agriculture tractor sales and hence supply management.

A-CAT Corp., a company that produces domestic electrical appliances in a poor region of India, largely caters to the price-sensitive rural market. During the past several months, there has been an alarming dip in sales of its major product, a voltage regulator that is used for varied purposes but most commonly as a protective device for refrigerators and television sets, to protect the latter from the vagaries of load fluctuations and/or frequent power failures, which are a very common phenomenon in the region. At the same time, the production department has been complaining about shortages of spares and components. Placing orders beyond a certain limit for the vital transformers used in most of its products has also stretched the system — whereas the company previously had access to four suppliers of transformers, now there is only one. The vice president has asked the chief operations manager to look into the problem. The operations manager traces the production planning process and its reliance on accurate forecasts. The manager’s job is to collect the data, analyze the data patterns, use forecasting methods, carry out back-testing and submit recommendations to management to solve the problem.

In mid-2008, the senior vice-president of Global Supply Chain at Elizabeth Arden in New York City was troubled with the challenges that lay before him. He had been hired to make sweeping changes to the company’s management of its supply chain, and he had already made a significant impact in forecasting, inventory control and service performance. His next move would require a radical consolidation of suppliers, make dramatic changes to inventory management, have a far-reaching impact on product development and require major lead time reductions. Given such a disruptive move, would current suppliers be able to meet expectations? Could the company’s current employees keep up with the pace of change expected? How many would have to be let go, and what would this do the morale of the workforce? Were significant results to shareholders really achievable? How much money would be saved, where would the savings come from and when would they be realized? The senior vice-president was determined to execute the re-engineering in a manner that would best address all these concerns.

The president and chief executive officer of Progistix-Solutions Inc. has asked an analyst to prepare an annual review of the Xerox Critical Parts Network for presentation to management in two weeks. The president expected the analyst to review the performance of the network and establish an improvement plan for the coming year, supported by specific goals and objectives. Although Xerox and Progistix had been satisfied with their relationship, after five years, both parties were interested in exploring ways to improve the network, particularly as competitors adopted similar approaches. In preparation for the meeting, the analyst wanted to explore opportunities in three specific areas. First, identify opportunities to improve depot operations. Second, he believed that opportunities existed to make additional improvements in the area of inventory management and he wondered how and where Progistix could work together with Xerox on such an initiative. Third, was to improve system-wide inventory turn performance by re-examining the cut-off point for filling the technicians' trunks with inventory. This case provides an opportunity for students to analyse a rapid-response supply chain and make recommendations for improvements. Class discussion can include issues related to supply chain partnerships, outsourcing, inventory management and demand forecasting. Data provided in the case allow students to develop implementation plans and set specific performance targets.

A privately managed school in Raipur, India, is faced with concerns from parents regarding long commutes faced regularly by students. The school has grown from a modest 89 students and 12 faculty members in 1993 to more than 2,700 students. Today, student commutes range from a few steps to several kilometres on school buses of varied capacities. While the transportation manager has been making adjustments to bus routes and capacity at the beginning of each term, the issue has become too large for one person to manage. In response, management decides to hire a consulting firm specializing in supply chain modeling to find a solution that would reduce not only students’ travel times but also fuel consumption and greenhouse gases emitted by the buses, thereby reducing the school’s carbon footprint.

A manufacturer of over 75 grades of styrenic resins — used to make DVD cases, refrigerator trays, packaging materials and auto parts — faces a “transition loss” each time it switches production from one grade to another. A transition loss for each grade arises from the initial 16 metric tons produced, which are sub-standard and unsuitable for usage by customers. To the company, this implies a loss of resources (raw material and production cost) and a disposal fee ($10,000) to remove each sub-standard production.

The case illustrates a sample of 15 grades for which data on their requirements for machine time usage, raw materials and labour hours are provided, as well as their production cost, selling price and market demand. Some of these grades must also be sold jointly in specific ratios. A newly hired sales executive must present an optimization template that would meet the company’s production constraints and maximize its profitability. Which grades of styrenic resins should be produced? Furthermore, how much of each grade should be produced?

Sinofert Holdings Limited, the largest comprehensive fertilizer enterprise in China, is trying to improve the profitability of its urea business. The company has invested a great deal of time and money but still reported losses in 2007 and 2009 and only a small profit in 2008. Sinofert both manufactures urea and purchases it from external suppliers, as well as distributing it to the provinces. Manufacturing costs, transportation costs, market prices, demand forecasts and manufacturing constraints are all known. An optimal distribution plan using linear programming can be compared to the plan derived by Sinofert management. Substantial profitability increases are shown to be possible, although the optimization reveals some issues with contract constraints. If the company is to make its urea business profitable, it needs a fresh look and a change in the way of doing business. The company’s chief analytics officer has been asked to look at the urea business and to provide recommendations to increase profitability.

The profit margin for the travel agency industry in Singapore, which mostly offered travel packages to Asia and Europe, was very thin. An up-and-coming travel agency faced the dilemma of offering maximum customer satisfaction while keeping its operating cost (e.g., fees for its tour guides) low. Rather than simply assigning travel guides to tours by trial and error, a director of the travel agency decided to use an optimization template. This case requires the development of an optimization template to advise management on the optimal assignment of tour leaders (within constraints of their availability and required rest periods) and generate maximum satisfaction among the customers. Considerations for tour-guide assignment include tour guides’ customer satisfaction levels, expertise on particular tours, visas for specific countries, and employment plans.

In the process of business development, many enterprises have to deal with issues from all dimensions of operations management including inventory management, distribution management, and network design. Sichuan Telecom, a branch of China Telecom Co. Ltd, which was a Fortune Global 500 company, had achieved its highest market share in its broadband business and maintained strong growth momentum in this segment. However, there was a serious inventory management problem concerning ADSL modems, a component that most broadband users required. The problem was that Sichuan Telecom's ADSL modem inventory was either too high or insufficient. To reduce inventory costs and improve the service level, the procurement manager conducted a comprehensive analysis of the company's sales and demand forecasting, procurement and suppliers, distribution management, warehouse management, and inventory management. This case follows the procurement manager in analyzing the company's existing operational management system for ADSL modems in order to discover the cause of the inventory problem and develop an effective plan to improve operations management.

End-of-month account closure at many firms often requires long work hours, which may lead to staff fatigue and attrition that will affect productivity and quality of work. This is true for GlaxoSmithKline’s Record to Report Finance team in Kuala Lumpur, Malaysia in August 2014. The company is a science-led global business that researches and develops a broad range of innovative products in three primary areas: pharmaceuticals, vaccines and consumer health care. The team in Malaysia has 40 employees who provide services including month-end accounts closure, financial reporting and analytics to business units operating in the Philippines, Malaysia, Brunei, Singapore, Australia, New Zealand, Indonesia, Thailand and Vietnam. At the end of every month, the team must perform within five days a sequence of 17 activities requiring varying man-hours. The activities must follow a specific flow according to information availability and must, for internal efficiency and quality control reasons, start and end on the same day. Is there a method by which management can help the team achieve work balance or minimize the number of work hours per day?

The (A) case involves managing the planning and execution of the first convocation held at one of the campuses of a business school in Nagpur, India, at fairly short notice. The school’s chairperson of post-graduate studies in management programs has been appointed as the chief co-ordinator of the event. Leveraging his operations-management background and working in collaboration with other faculty, he sets about identifying the required activities and their precedence relationships in order to ascertain the time required to complete these activities.

The (B) case 9B13D004 presents a situation that arises about three weeks into the project that necessitates some replanning in midstream.

The emergency department of any large hospital is frequently subject to substantial patient crowding, a result of arrivals by foot and ambulance, and limited resources. The San Francisco General Hospital is particularly crowded due to its prominence as the only trauma centre in the city. As a result, it is on ambulance diversion almost 25 per cent of the time, more than any other hospital in the area. Hospital managers are looking for ways to alleviate emergency department crowding and ambulance diversion.

CPSim2 is a Critical Path Simulator that runs under MS Windows. Participants use the simulator to manage the construction of an automated factory - a fairly complex, 43-activity project that must be completed in 107 days if penalties are to be avoided. As project manager, students must make effective trade-offs between the costs incurred by crashing (speeding up) activities, and the financial penalties for late completion. Unforeseen delays and speedups occur during the project, which require timely response. Although these appear random, each user of the simulator is exposed to the same events during the project. This allows performances and strategies to be compared within a class and between classes. CPSim2 maintains a current display of the project's CPM network, as well as the critical path(s) and activity slacks. The time required to complete the exercise is controlled by CPSim2, and does not exceed 60 minutes. This product provides the student instructions on the running of the simulation; the software itself is distributed with a site license for an additional annual license fee (product 7B06D002) - contact Ivey Publishing for pricing and distribution information.

An eight-mile stretch of the US-202 South near Philadelphia, USA, exhibits classic day-dependent traffic congestion problems. During certain parts of the day, traffic flows freely and without delays. During other parts of the day, however, traffic can be highly congested, and significant delays occur. This case and the subsequent (B) case center on trying to determine (1) what data to collect, and (2) what modeling approach to use in order to estimate the expected total travel time.

This case chronicles the challenges of establishing an innovative tissue bank service to accelerate the research and development processes of biotechnology and pharmaceutical companies worldwide. Asterand’s two major challenges involved achieving a standardized approach to collecting tissue samples in hospitals all over the world and achieving the highest possible quality of tissue samples shipped to their primary customer, Amgen. Despite the identified need for high-quality tissue samples, Asterand was experiencing multiple quality control problems in their processes and procedures. Tissue samples were being packaged poorly, labeled incorrectly or delivered at the wrong time or to the wrong place. Additionally, there were quality issues with the RNA analysis of the samples, which was a critical factor in the usability of the tissue sample for research and development of new therapies and drugs.

The head of pathology at Amgen’s California facility was threatening to terminate their existing order and communicate the failure of Asterand to all company employees, which would have a devastating ripple effect across the industry and likely destroy opportunities for any future orders with Asterand. If this happened, Asterand would not be able to secure contracts with customers and was at risk of losing investors and going bankrupt.

In the winter of 2010 in Shanghai, Dr. Zeb Feng, procurement director for Asia at British Petroleum (BP), was acutely aware of the growing burden that quality control imposed over his company’s global operations. Chinese suppliers were masters of cost-cutting, but quality often suffered as a result, which led in turn to an increased need for inspection and development efforts. Almost five years ago, Feng’s company had established an international procurement office (IPO) in Shanghai, which served as a shared service centre for internal customers throughout BP worldwide. Since that time, the IPO had been mainly sourcing non-hydrocarbon goods and services.

After a corporate board meeting with Christina De Luca, the vice president of procurement and supply chain management for BP’s downstream operations, it had been decided that the company would start to enhance its global competitive sourcing. As the number-one supplier market in the world, China was a high priority for further oil exploration. The pressing point that concerned Feng was whether Chinese suppliers were sufficiently ready to supply mission-critical supplies for oil drilling, extraction, and refining. During a recent conference call, De Luca had reiterated, “Zeb, our competitors are way ahead of us in their sourcing operations, and they have achieved much lower costs. We’ve got to do something!” Feng had to gather his team for a planning meeting. He knew that supply quality was the key issue, but how could it be resolved?
