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.

Managing Project Portfolios, Martin Lockett, Bert De Reyck, Andrew Sloper
Research Collection Lee Kong Chian School Of Business
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 …
When The Client Comes First, Bee Lian Ang
When The Client Comes First, Bee Lian Ang
Social Space
When donors, government and other funders provide support, they want assurances that the daily living conditions and lives of the beneficiaries are actually improved. The one question that is often asked is: What is the outcome of the help or service rendered? The science of determining outcomes, or outcome management, has its roots in social science evaluation research. Besides being used as a tool to evaluate the achievement of client outcomes, it is also a valuable management tool.
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 …
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 …

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 …

In a of subassembly lines, balance becomes more difficult to achieve as it requires that all subassembly lines be synchronized to produce at the same rate. We show how to adapt the ‘‘bucket brigade’’ protocol of work-sharing so that balance emerges spontaneously.
Mabs: Spreadsheet– Based Decision Support For Precision Marketing, Bert De Reyck, Zeger Degraeve
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
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 …

Hospitals need to repeatedly produce duty rosters for its nursing staff. The good scheduling of nurses has impact on the quality of health care, the recruitment of nurses, the development of budgets and other nursing functions. The nurse rostering problem (NRP) has been the subject of much study. This paper presents a brief overview, in the form of a bibliographic survey, of the many models and methodologies available to solve the NRP.

The last decade has witnessed a shift from a focus on the value created by a single firm and product to an examination of the value created by networks of firms (or product ecosystems) in which assets are comingled with external entities. The authors examine these market-based assets in the context of network markets and propose an Integrated Networks model in which three types of networks—user, complements, and producer—add value or enhance the attractiveness of the associated focal product. The authors empirically test the proposed model by surveying information technology professionals on their resource allocation decisions regarding the Unix and …

The Choice Between Joint Venture And Wholly Owned Subsidiary: An Institutional Perspective, Daphne W. Yiu, Shige Makino
Research Collection Lee Kong Chian School Of Business
The study of foreign entry-mode choice has been based almost exclusively on transaction-cost theory. This theory focuses mainly on the impacts of firm- and industry-specific factors on the choice of entry mode, taking the effects of country-specific contextual factors as constant or less important. In contrast, the institutional perspective emphasizes the importance of the influence of both institutional forces embedded in national environments and decision makers' cognitive constraints on the founding conditions of new ventures. Still, this theoretical perspective has yet to provide insights into how institutional factors influence the choice of foreign entry mode. The primary goal of the …

Exchanging Preliminary Information In Concurrent Engineering: Alternative Coordination Strategies, Christian Terwiesch, Christoph H. Loch, Arnoud De Meyer
Research Collection Lee Kong Chian School Of Business
Successful application of concurrent development processes (concurrent engineering) requires tight coordination. To speed development, tasks often proceed in parallel by relying on preliminary information from other tasks, information that has not yet been finalized. This frequently causes substantial rework using as much as 50% of total engineering capacity. Previous studies have either described coordination as a complex social process, or have focused on the frequency, but not the content, of information exchanges. Through extensive fieldwork in a high-end German automotive manufacturer, we develop a framework of preliminary information that distinguishes information precision and information stability. Information precision refers to the …

The small-office/home-office (SOHO) professionals comprise the fastest growing segment in the labor force today. Typically being a one-person business based at home, SOHO owners mostly rely on office information technology to single handedly run their entire operation. Despite the segment's ostensibly growing dependence and influence on the information technology industry, still very little is known about the dynamics between SOHO and IT products. With the purpose of addressing this void, the SOHO professionals' adoption patterns of multigenerational IT products are ivestigated. Accordingly, an individual SOHO-level initial- and repeat-purchase logit model that captures the procurement patterns for successive generations of technological …
