Optimal Investment Under Operational Flexibility, Risk Aversion, And Uncertainty, Michail Chronopoulos, Bert De Reyck, Afzal Siddiqui

Research Collection Lee Kong Chian School Of Business

Traditional real options analysis addresses the problem of investment under uncertainty assuming a risk-neutral decision maker and complete markets. In reality, however, decision makers are often risk averse and markets are incomplete. We confirm that risk aversion lowers the probability of investment and demonstrate how this effect can be mitigated by incorporating operational flexibility in the form of embedded suspension and resumption options. Although such options facilitate investment, we find that the likelihood of investing is still lower compared to the risk-neutral case. Risk aversion also increases the likelihood that the project will be abandoned, although this effect is less …

Outpacing Moore’S Law: Information Technology’S Role As An Enabler, Kevin P. Duffy

Management Information Systems Faculty Publications

Technology is widely recognized as an enabler of business models. When the Web appeared in the 1990s, businesses redesigned the ways in which they interacted with their customers. They became global, rather than local, and the world represented an expanded customer base. While the Web has become a fact of life since the 1990s, technology has not lost its ability to introduce new ways of enabling organizations to provide and create value for their customers, as new and inventive ways of interacting with customers continue to appear.

The US Air Force is the largest consumer of energy in the federal government, spending 9 billion in 2008 to fuel aircraft and ground vehicles as well as provide energy to installations.¹ In that same year, the Air Force s fuel bill of 7 billion amounted to more than half of the US government s total fuel cost.² Because of the critical and central role that energy plays in completion of the Air Force’s mission, the secretary of the Air Force has developed an Air Force energy plan supported by three pillars Reduce Demand, Increase Supply, and Culture …

Valuation Of Risky Projects And Other Illiquid Investments Using Portfolio Selection Models, Janne Gustafsson, Bert De Reyck, Zeger Degraeve, Ahti Salo

Research Collection Lee Kong Chian School Of Business

We develop a portfolio selection framework for the valuation of projects and other illiquid investments for an investor who can invest in a portfolio of private, illiquid investment opportunities as well as in securities in financial markets, but who cannot necessarily replicate project cash flows using financial instruments. We demonstrate how project values can be solved using an inverse optimization procedure and prove several general analytical properties for project values. We also provide an illustrative example on the modeling and pricing of multiperiod projects that are characterized by managerial flexibility.

Mixed 0-1 Linear Programs Under Objective Uncertainty: A Completely Positive Representation, Karthik Natarajan, Chung-Piaw Teo, Zhichao Zheng

Research Collection Lee Kong Chian School Of Business

In this paper, we analyze mixed 0-1 linear programs under objective uncertainty. The mean vector and the second moment matrix of the nonnegative objective coefficients is assumed to be known, but the exact form of the distribution is unknown. Our main result shows that computing a tight upper bound on the expected value of a mixed 0-1 linear program in maximization form with random objective is a completely positive program. This naturally leads to semidefinite programming relaxations that are solvable in polynomial time but provide weaker bounds. The result can be extended to deal with uncertainty in the moments and …

Resource Maps For Fresh Meat Across Retail And Wholesale Supply Chains, Peter Whitehead, Martin Palmer, Carlos Mena, Adrian Williams, Christine Walsh

Business Faculty Publications and Presentations

Consumers spend more money on meat than any other food item. WRAP has already shown that households are wasting around 570,000 tonnes of fresh meat each year, of which 260,000 (46%) is avoidable with a value of about £1,300M. These wasted products also include embedded water and embedded carbon. This research has focused on the supply of meat from the farm gate onwards, including livestock slaughtering, meat preparation, processing and packaging, distribution and retail. It focuses on fresh meat from the four animal species which comprise some 96% by weight of all animals slaughtered for human consumption, namely chickens, cattle, …

Fruit And Vegetable Resource Maps: Mapping Fruit And Vegetable Waste Through The Wholesale Supply Chain, Leon A. Terry, Carlos Mena, Adrian Williams, Nigel Jenney, Peter Whitehead

Business Faculty Publications and Presentations

Research by WRAP has shown that households waste around three million tonnes of fruit and vegetables per year, raising concerns about the economic and environmental impacts of food waste. This study has been conducted to quantify the level of loss and waste of fruit and vegetables before they reach consumers, through the retail and wholesale supply chain. Furthermore, the study determined how, where and why the product was wasted.

Eleven fresh produce types were selected based on their consumption, post-harvest physiology and management. The 11 products chosen were strawberries, raspberries, tomatoes, lettuce, apples, onions, potatoes, brassicas, citrus, avocados and bananas; …

Food Safety And Cage Egg Production

Agribusiness Reports

States have begun legislating against cage egg production and dozens of major U.S. food retailers, restaurant chains, and foodservice providers—as well as hundreds of U.S. universities—are switching to cage-free eggs. Extensive scientific evidence strongly suggests this trend will improve food safety. All sixteen scientific studies published in the last five years comparing Salmonella contamination between caged and cage-free operations found that those confining hens in cages had higher rates of Salmonella, the leading cause of food poisoning related death in the United States. This has led prominent consumer advocacy organizations, such as the Center for Food Safety, to oppose the …

Leveraging Complex Event Processing For Smart Hospitals Using Rfid, Wen Yao, Chao-Hsien Chu, Zang Li

Research Collection School Of Computing and Information Systems

RFID technology has been examined in healthcare to support a variety of applications such as patient identification and monitoring, asset tracking, and patient–drug compliance. However, managing the large volume of RFID data and understanding them in the medical context present new challenges. One effective solution for dealing with these challenges is complex event processing (CEP), which can extract meaningful events for context-aware applications. In this paper, we propose a CEP framework to model surgical events and critical situations in an RFID-enabled hospital. We have implemented a prototype system with the proposed approach for surgical management and conducted performance evaluations to …

Logistics Service Orientation: An Integrated Strategy To Build Logistics Service Competency, Mert Tokman, R. Glenn Richey, Haozhe Chen

Journal of Transportation Management

While the importance of logistics service competency is widely acknowledged, more research is needed to investigate its antecedents. In this conceptual paper, we synthesize extant marketing and logistics/supply chain literature and propose a new concept - logistics service orientation, which consists of both logistics service’s internal and external market orientation. It is argued that a firm’s logistics service orientation has direct impacts on its logistics service performance. In addition, it is also proposed that this impact can be indirectly achieved through enhanced internal integration. This research contributes to existing knowledge by offering new insights on the development of logistics service …

Identifying Traffic Count Posts For Origin-Destination Matrix Adjustments: An Approach To Actual Size Networks, Saeed Asadi Bagolee, Mohsen Asadi, Lorna Richardson

Journal of Transportation Management

For transportation planners, the use of Origin-Destination (OD) matrix adjustment, is receiving considerable attention. However, there are concerns about the validity of results, primarily related to the number and location of traffic count posts. This leads to the question “What would be the best set of traffic count posts to use in OD matrix adjustment modules?” It has been proved that solving this problem is cumbersome. There have been several attempts (either exact or heuristic approaches) to address this problem. But due to the inherent complexities, there is no efficient and easy-to-use methodology able to address situations on the scale …

The Selection Of Transshipment Ports Using A Hybrid Data Envelopment Analysis/Analytic Hierarchy Process, Byung-In Park, Hokey Min

Journal of Transportation Management

The accelerated globalization of logistics activities over the last several decades has spurred a rapid expansion of port facilities all cross the world. However, the recent slowdown of international trade, coupled with a global financial crisis, has created an on-going glut of international port facilities throughout the world. Although the abundance of port facilities provides more transshipment options for carriers and shippers, it makes the port selection decision more complex and difficult. To cope with this new set of challenges, this paper proposes a hybrid data envelopment analysis (DEA)/ analytic hierarchy process (AHP) model that is designed to identify factors …

The Implementation Of Total Quality Management (Tqm) In Oil And Gas Industry In Indonesia., Wakhid Slamet Ciptono

Student Works (2010-2019)

The changing environment in an organization is forcing the organization itself to find a plan of an integrated management framework and an adequate performance measurement. Failure in planning means planning a failure of an organization. Finding out the critical factors of quality management practices (QMP), the mediation of the contextual factors (world-class company practice or WCC, operational excellence practice or OE, company non financial performance or CNFP), and company financial performance or CFP is becoming the way that would facilitate the sustainability of TQM implementation model. This empirical study is aimed to assess how TQM (Total Quality Management)—a holistic management …

The Impact Of Environmental Factors On Internal Integration In Support Of Supply Chain Management, Mohammed I. Alzaben

Theses and Dissertations

Despite the recognized importance of cross-functional integration in support of supply chain management by scholars and practitioners, integration remains an elusive goal in today's competitive market. Specifically, scholars have identified three environmental factors as potential barriers to interdepartmental integration. A review of the literature indicates that very little research has examined potential environmental barriers to the integration between logistics and other functions. This paper is an exploratory study that seeks to fill this gap by using secondary data collected from over 1,500 mid-level managers and a structural equations model to test which environmental factors could be potential barriers.

By Product Synergy Analysis, Francisco Edgardo Leguiza

Theses and Dissertations

The United States Air Forces generates various waste during the repair and overhaul activities. These wastes can involve hazardous material. Depending on the material, technologies exist or could be readily developed to convert wastes into feed-stock for other processes. The old concept of managing material from cradle-to-grave now has evolved into cradle-to-cradle. This concept goes beyond the disposal of waste and can be even more cost-effective than recycling. The objective is to generate "food" by identifying and developing other processes to use current wastes in its own production processes. By shifting from waste disposal to an endless reusing model improves …

Effect Of The Prolactin-Release Inhibitor Quinagolide On Lactating Dairy Cows, P. Lacasse, V. Lollivier, R. Bruckmaier, Y. R. Boisclair, G. F. Wagner, M. Boutinaud

Farm Animal Husbandry Collection

In most mammals, prolactin (PRL) is essential for maintaining lactation, and yet the short-term suppression of PRL during established lactation by bromocriptine has produced inconsistent effects on milk yield in cows and goats. To assess the effect of the long-term inhibition of PRL release in lactating dairy cows, 5 Holstein cows in early lactation received daily intramuscular injections of 1 mg of the PRL-release inhibitor quinagolide for 9 wk. Four control cows received the vehicle (water) only. During the last week of the treatments, one udder half was milked once a day (1×) and the other twice a day …

Understanding Port Choice Behaviour: A Network Perspective, Loon Ching Tang, Joyce M. W. Low, Shao Wei Lam

Research Collection Lee Kong Chian School Of Business

A novel Network-based Integrated Choice Evaluation (NICE) model is developed to enhance the multinomial logit preference (MNL) model that is widely employed in the existing port choice literature. The NICE model integrates the element of port service network with observational port attributes to identify important quality characteristics on which liner shipping companies base their port choices. An empirical study of the proposed model is conducted through the service schedules of three established liner shipping companies. Results show that port efficiency and scale economies are the more important dimensions influencing liner shipping companies’ selection of major Asian ports. Nevertheless, it is …
