Case Studies

In early 2016, LUX* Resorts & Hotels, a hotel group headquartered in Mauritius, needed to determine the room mix to sell to foreign guests to achieve a specific earnings target. The hotel group also intended to sell some of the remaining rooms to local residents at affordable (discounted) prices. The objective was to maximize the revenue stream to finance local corporate social responsibility projects. The case highlights the practical use of Microsoft Excel Solver, an optimization tool, to resolve routine planning challenges faced by a hotel group.

AWARD WINNING CASE – This case won the Best Teaching Case Studies Award at the Decision Sciences Institute (DSI), 2015. In 2014, as one of the most well-known Taiwanese cuisine brands, Din Tai Fung operated more than 100 restaurants around the world. Attracted by its signature xialongbao (soup dumpling), long queues of customers at Din Tai Fung’s storefront were a common sight. Requests for partnerships for global expansion were constantly arriving. Customer feedback from overseas, however, suggested a notable gap in service quality between the overseas and Taiwanese branches. The demand for support by overseas branches had also surged significantly due to the fast pace of growth in recent years. The company’s chief executive officer had deferred his plan to open the 10th branch in Taiwan. Nevertheless, plans to open new branches in overseas markets were enthusiastically evaluated by existing partners. Two new potential partnership offers from Dubai and the Philippines were being aggressively pursued. What was the best way to cope with the increasing number of requests for support from overseas branches and to ensure high quality? Should Din Tai Fung approve the two overseas offers for partnership that seemed promising? What was the best overseas expansion strategy?

In July 2015, PT Trias Indra Saputra (TRIAS), Indonesia’s leading welded cable ladder producer, had just won its largest-ever tender bid. The news could get even better if it adopted alternative materials that were potentially more profitable. The production director was tasked with weighing whether TRIAS should fulfill the tender using its traditional supplier or the new materials. While more expensive, the new materials would cut out several production processes and associated costs. However, using the new suppliers presented significant risks. Only two mills, in Korea and Japan, supplied the appropriate material, and both companies presented different prices and import costs. Since TRIAS could be penalized if it did not supply the goods on time, the production manager also had to calculate the likelihood that each company could be delayed in supplying the order and how much that would reduce profits if it happened.

APLO was a reputable supplier of LED lighting systems for diverse countries from Taiwan to the United Kingdom. In 2015, APLO signed a contract to supply and install 30,000 pieces of 60-watt ecological street lights in several towns within one of Indonesia’s provinces. With over 250 million inhabitants, Indonesia was in dire need of modernizing its infrastructure as it expanded economically. Having already been contracted for street lighting in several parts of Jakarta, Indonesia’s capital city, APLO was eager for more projects across Indonesia. Would APLO be able to make this its showcase project and win many more contracts throughout Indonesia’s 34 provinces?

In December 2014, after receiving poor service on a flight, a senior vice president at Korean Air lashed out at the flight attendants and delayed the flight’s departure until the chief attendant was returned to the gate. Following a tepid apology from her father, Korean Air’s chief executive officer, her actions drew a public backlash because they exposed the sense of entitlement prevalent among rich family conglomerates in South Korea. How should she have reacted in the face of the service failure? Why had she become the target of a public backlash? What could Korean Air do to mitigate the negative effects of this incident?

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?

Leading analytics firm, Insights Global Analytics, handled many analytics processes and projects requiring extensive domain and statistical expertise. Employees with prior analytics experience had skill-sets that could be utilized for other projects. Analysts and consultants working on business research projects had strong domain knowledge about various technological trends. However, sometimes one team did not know about the rich skills possessed by another team. To build a knowledge-sharing culture that would facilitate the incubation of new ideas, spread different skills across the organization, break the silos among teams and promote free exchange of ideas among employees the company decided to implement a knowledge management (KM) program. A team was appointed with the challenge of selecting an appropriate cost-effective technology that would achieve the objective of fostering a knowledge-sharing culture.

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?
