Exploiting Metaheuristics To Strategize On Performance-Based Logistics Contracts For Mro Services, Arnd Schirrmann, Elaine Wong, Zhichao Zheng
Research Collection Lee Kong Chian School Of Business
An inherent challenge of using Performance-Based Logistics (PBL) contracts for aircraftmaintenance, repair and overhaul (MRO) services is pricing. As with traditional bricks andmortar services, under-priced contracts cannot cover costs, while overpriced contracts loseout to competition. Furthermore MRO services have an additional element of uncertainty.Performance uncertainties arise due to the inability to accurately forecast demand of spareparts, while cost uncertainties are a result of globally distributed operations subjected tofluctuating economic conditions. Previous work to solve this contracting problem adoptedthe principal-agent model, obtaining an optimal solution from the perspective of both riskaverseparties (i.e., a price-sensitive customer and a profit-driven service provider). Thiswork …

Effective Project Planning: Making The Most Of Project Planning Tools, Bert De Reyck
Research Collection Lee Kong Chian School Of Business
Although project planning tools such as Microsoft Project and Primavera have become indispensable tools for supporting the project planning process in a wide variety of industries and organizations, many companies do not use these tools in the best possible way, resulting in disappointment and frustration as well as a lack of effective project management support. In this article, we propose several guidelines on what to do,

Using Decision Analysis To Value R&D Projects, Bert De Reyck
Using Decision Analysis To Value R&D Projects, Bert De Reyck
Research Collection Lee Kong Chian School Of Business
Project portfolio management, the equivalent of financial portfolio management but focused on R&D projects rather than financial assets, often relies on decision analysis methods to value projects rather than traditional financial valuation methods such as net present value (NPV). In finance, the idea of managing portfolios of assets goes back a long time, with the first formal methods being developed in the 1950s. Simply put, assembling a portfolio of stocks, bonds, and other financial instruments balances the risk a manager is taking with any one of the investments. Over time, this same idea has also taken hold for managing a …

Convergence Of Corporate Governance: Critical Review And Future Directions, Toru Yoshikawa, Abdul A. Rasheed
Research Collection Lee Kong Chian School Of Business
Research Question/Issue: Convergence in corporate governance across countries has been a subject of interest and controversy in a variety of disciplines. We attempt to address a number of related research questions: (1) what constitutes convergence? (2) what are the drivers that propel corporations in different nations towards convergence? (3) what are the major impediments that stand in the way of convergence? (4) what empirical evidence do we have to suggest that we are moving towards or away from convergence? and (5) what would be some productive avenues for further research on this topic? Research Findings/Results: Despite the vigorous intellectual position …
A Hybrid Scatter Search For The Discrete Time/Resource Trade-Off Problem In Project Scheduling, Mohammad Ranbar, Bert De Reyck, Fereydoon Kianfar
A Hybrid Scatter Search For The Discrete Time/Resource Trade-Off Problem In Project Scheduling, Mohammad Ranbar, Bert De Reyck, Fereydoon Kianfar
Research Collection Lee Kong Chian School Of Business
We develop a heuristic procedure for solving the discrete time/resource trade-off problem in the field of project scheduling. In this problem, a project contains activities interrelated by finish-start-type precedence constraints with a time lag of zero, which require one or more constrained renewable resources. Each activity has a specified work content and can be performed in different modes, i.e. with different durations and resource requirements, as long as the required work content is met. The objective is to schedule each activity in one of its modes in order to minimize the project makespan. We use a scatter search algorithm to …
The Emergence Of Justice Climate In Groups, Teams, And Organizations: A Theory Of Multilevel Information Aggregation And Judgment, D. Rupp, Elizabeth Layne Paddock
The Emergence Of Justice Climate In Groups, Teams, And Organizations: A Theory Of Multilevel Information Aggregation And Judgment, D. Rupp, Elizabeth Layne Paddock
Research Collection Lee Kong Chian School Of Business
We outline a theoretical model of the emergence of justice climate in groups, teams, and organizations, and in doing so integrate multiple justice perspectives (e.g., affective events, fairness heuristic, deonance, justice integration, multifoci justice, overall justice). We propose that justice climate is spawned at the event level, where individuals use their emotional reactions to situations as information in forming fairness judgments. Over time, these judgments about various perpetrators--which may include the evaluation of outcomes, procedures, information, and interpersonal treatment--are aggregated to form individual-level stable judgments regarding the fairness of exchange partners with whom employees interact (e.g., supervisors, co-workers, customers). Through …

Stock prices are based in large part on corporate financial statements, augmented by analysis by stock analysts. The ultimate goal of any marketing expenditure should be to increase the value of the firm, but the road from marketing expenditure to stock price is usually circuitous. This is because marketing’s path to financial impact is through revenues, and the road to revenues runs through the customer.

Portfolios are part of the bedrock of any financial services company. Yet, other industries are now starting to use a similar approach -not with stocks and bonds, but with business projects. Martin Lockett, Bert De Reyck and Andrew Sloper think it's a great idea, but only if it's done right.
R&D Project Scheduling When Activities May Fail, Bert De Reyck, Roel Leus
R&D Project Scheduling When Activities May Fail, Bert De Reyck, Roel Leus
Research Collection Lee Kong Chian School Of Business
An R&D project typically consists of several stages. Due to technological risks, the project may have to be terminated before completion, each stage having a specific likelihood of success. In the project planning and scheduling literature, this technological uncertainty has typically been ignored and project plans are developed only for scenarios in which the project succeeds. In this paper we examine how to schedule projects in order to maximize their expected net present value when the project activities have a probability of failure and when an activity's failure leads to overall project termination. We formulate the problem, show that it …
Project Options Valuation With Net Present Value And Decision Tree Analysis, Bert De Reyck, Zeger Degraeve, Roger Vandenborre
Project Options Valuation With Net Present Value And Decision Tree Analysis, Bert De Reyck, Zeger Degraeve, Roger Vandenborre
Research Collection Lee Kong Chian School Of Business
Real options analysis (ROA) has been developed to correctly value projects with inherent flexibility, including the possibility to abandon, defer, expand, contract or switch to a different project. ROA allows computing the correct discount rate using the replicating portfolio technique or risk-neutral probability method. We propose an alternative approach for valuing Real Options based on the certainty-equivalent version of the net present value formula, which eliminates the need to identify market-priced twin securities. In addition, our approach can be extended to the case of multinomial trees, a useful tool for modeling uncertainty in projects. We introduce within decision tree analysis …
Rethinking The Role Of Management Consultants As Disseminators Of Business Knowledge: Knowledge Flows, Directions, And Conditions In Consulting Projects, Andrew Sturdy, Karen Handley, Timothy Adrian Robert Clark, Robin Fincham
Rethinking The Role Of Management Consultants As Disseminators Of Business Knowledge: Knowledge Flows, Directions, And Conditions In Consulting Projects, Andrew Sturdy, Karen Handley, Timothy Adrian Robert Clark, Robin Fincham
Research Collection Lee Kong Chian School Of Business
Consultants are seen as core agents in the dissemination of business knowledgethrough their relative expertise and/or rhetorical and knowledge management practices.However, relatively few studies focus specifically on their role in projects with clientorganisations. This paper examines knowledge flow in consultancy projects fromlongitudinal observation and interview research as well as a survey of clients andconsultants working together. Our analysis suggests that the conventional view ofconsultants as disseminators of new management ideas to clients is, at best,exaggerated and certainly misrepresents their role in project work. Firstly, it tends tooccur by default rather than by design. More importantly however, learning is oftenconcerned with …

On The Integration Of Production And Financial Hedging Decisions In Global Markets, Qing Ding, Lingxiu Dong, Panos Kouvelis
Research Collection Lee Kong Chian School Of Business
We study the integrated operational and financial hedging decisions faced by a global firm who sells to both home and foreign markets. Production occurs either at a single facility located in one of the markets or at two facilities, one in each market. The company has to invest in capacity before the selling season starts when the demand in both markets and the currency exchange rate are uncertain. The currency exchange rate risk can be hedged by delaying allocation of the capacity to specific markets until both the currency and demand uncertainties are resolved and/or by buying financial option contracts …

Infrastructure can be unreliable and administration subject to corruption in Asia’s rapidly emerging economies. This context presented Singapore with unique opportunities to export its expertise to locations where these attributes are less certain, through the provision of superior infrastructure, the ability to negotiate investment concessions and, where existing, through the links to influential business groups in the investment location. This strategic initiative is further premised on the perception that Singapore’s positive reputation with multinationals, as well as ‘guanxi’, or connections, with Asian business networks, will give the industrial-township projects a marketing advantage. Their progress is a litmus test of Singapore’s …

Mabs: Spreadsheet– Based Decision Support For Precision Marketing, Bert De Reyck, Zeger Degraeve
Research Collection Lee Kong Chian School Of Business
In this paper, we describe a decision support system developed for automatically scheduling and optimising broadcasts of advertisements to mobile phones via SMS (Short Message Service) text messaging. The system, MABS or “Mobile Advertising Broadcast Scheduler”, is developed in Microsoft Excel with a link to Lingo, a modelling language and IP solver. It was developed for a London-based company specialized in location-sensitive precision marketing via mobile phones. The system significantly reduced the time required to schedule the broadcasts, and resulted both in increased customer response and revenues.

A Hybrid Scatter Search/Electromagnetism Meta-Heuristic For Project Scheduling, Dieter Debels, Bert De Reyck, Roel Leus, Mario Vanhoucke
Research Collection Lee Kong Chian School Of Business
In the last few decades, several effective algorithms for solving the resource-constrained project scheduling problem have been proposed. However, the challenging nature of this problem, summarised in its strongly NP-hard status, restricts the effectiveness of exact optimisation to relatively small instances. In this paper, we present a new meta-heuristic for this problem, able to provide near-optimal heuristic solutions for relatively large instances. The procedure combines elements from scatter search, a generic population-based evolutionary search method, and from a recently introduced heuristic method for the optimisation of unconstrained continuous functions based on an analogy with electromagnetism theory. We present computational …
Dynamic Pricing Through Discounts For Optimizing Multiple Class Demand Fulfillment, Qing Ding, Panos Kouvelis, Joseph M. Milner
Dynamic Pricing Through Discounts For Optimizing Multiple Class Demand Fulfillment, Qing Ding, Panos Kouvelis, Joseph M. Milner
Research Collection Lee Kong Chian School Of Business
In a multiple-customer-class model of demand fulfillment for a single item, we consider the use of dynamic price discounts to encourage backlogging of demand for customer classes denied immediate service. Customers are assumed to arrive over several stages in a period, and customer classes are distinguished by their contractual price and sensitivity to discounts. Through dynamic programming we determine the optimal discounts to offer, assuming a linear model for the sensitivity of customers to such inducements. We show that customers are served in class order, and allocation of inventory to demand is determined by considering the current number of customers …

Hybridizing Discrete- And Continuous-Time Models For Batch Sizing And Scheduling Problems, Siqun Wang, Monique Guignard
Research Collection Lee Kong Chian School Of Business
This paper proposes a new hybrid technique called partial parameter uniformization (hereafter PPU). The technique simplifies problems by ignoring the different values that certain problem parameters can take, which may facilitate the solution of some hard combinatorial optimization problems. PPU is applied to complex batch sizing and scheduling problems. Some information can be obtained from a discrete-time model in which job durations have been made uniform. This information is then exploited by a more detailed continuous-time model to generate feasible solutions and further improve these solutions. Good, or optimal solutions to the Westenberger and Kallrath Benchmark problems have been obtained …

Against the background of a rapidly changing business environment, the article examines the organizational change management behavior of the owner-managers of small and medium-sized enterprises in Singapore. The analysis of survey data is aimed at ascertaining whether there are any differences between Chinese and English-educated small (Chinese) businessmen in terms of Change Management (CM), a dichotomy that is of great historical and politico-cultural significance in Singapore. The survey data show that there are indeed differences between the subgroups (e. g. with regard to the initiation of a more participatory people management style) but these variations turned out to be far …

The ever-increasing penetration of projects as a way to organise work in many organisations necessitates effective management of multiple projects. This has resulted in a greater interest in the processes of project portfolio management (PPM), with more and more software tools being developed to assist and automate the process. Much of the early work on PPM concentrated on the management of IT projects, largely from the perspective of the management of resources and risk. Many of the recent articles have been by vendors of the software, promoting the value of the PPM process. However, the claims made in those articles …
Tools To Keep Projects On The Rails - The Completion Of Projects On Time And To Budget Often Seems An Elusive Goal, But Success Rates Can Be Improved With The Application Of Risk Management Techniques, Bert De Reyck
Research Collection Lee Kong Chian School Of Business
In 2004 the Standish group, a research company that produces annual reports on IT projects carried out in the US, reported that only 29 per cent of these projects were considered a success, with the vast majority running over time and over budget. Cost overruns averaged 56 per cent of original budgets, and projects took on average 84 per cent longer than originally anticipated. Anecdotal evidence suggests that things are not much better elsewhere. The construction of the new Wembley Stadium in London is two months behind schedule and Pounds 45m over budget. And the West Coast Mainline project, which …
On ‘‘Investment Decisions In The Theory Of Finance: Some Antinomies And Inconsistencies’’, Bert De Reyck
On ‘‘Investment Decisions In The Theory Of Finance: Some Antinomies And Inconsistencies’’, Bert De Reyck
Research Collection Lee Kong Chian School Of Business
In the paper “Investment Decisions in the Theory of Finance: Some antinomies and inconsistencies”, Magni [Eur. J. Operat. Res. 137 (2002) 206] shows that using the net present value rule for making investment decisions can lead to inconsistencies and antinomies. The author claims that the so-called equivalent-risk tenet of finance, whereby an investor needs to compare an investment opportunity with an asset of equivalent risk, is impossible to implement. In this paper, we show that the main thesis of this paper is incorrect, and that finance theory, when applied correctly, can be used to value investment projects by comparing assets …
A Social Exchange Model Of Subordinate's Trust In Supervisors, Wei Hua
A Social Exchange Model Of Subordinate's Trust In Supervisors, Wei Hua
Research Collection Lee Kong Chian School Of Business
This study demonstrates how the subordinate’s defensiveness predicts perception of managerial behaviors, which in turn leads to trust in supervisors. From a social information processing perspective, defensiveness, the affective reaction to uncertainty and vulnerability, serves as the frame subordinates use to decode and evaluate managerial behaviors. Trust in supervisors is anchored in this perception. A two-group analysis in Structural Equation Modeling (SEM) is used to test this model by a Chinese and a US sample

In the stochastic multiperiod inventory problem, a vast majority of the literature deals with demand volume uncertainty. Other dimensions of uncertainty have generally been overlooked. In this paper, we develop a newsboy formulation for the aggregate multiperiod inventory problem intended for products of short sales season and without replenishments. A distinguishing characteristic of our formulation is that it takes a time dimension of demand uncertainty into account. The proposed model is particularly suitable for applications in haute couture, i.e., high fashion industry. The model determines the time of switching primary sales effort from one season to the next as well …
