Flexible Vs. Dedicated Technology Choice In The Presence Of Multiproduct Subscription Programs, Liling Lu, Onur Boyabatli, Sarah Yini Gao
Flexible Vs. Dedicated Technology Choice In The Presence Of Multiproduct Subscription Programs, Liling Lu, Onur Boyabatli, Sarah Yini Gao
Research Collection Lee Kong Chian School Of Business
Recently, automotive manufacturers have started offering multi-car subscription programs that give customers access to a menu of car models with possibility of switching between the models. The maintenance and depreciation costs during the program are borne by the manufacturers before the cars are sold in the pre-owned market. This paper studies how offering such a subscription program shapes the firm’s flexible versus dedicated technology choice and capacity investment decisions. We consider a two-product firm that makes these decisions under uncertain demand in a single subscription period. The firm faces two types of demand based on which product is requested at …

Knowledge “Hiding And Seeking” During The Pandemic: Who Really Wins In The New Normal?, Kim-Lim Tan, Ivy S. H. Hii, Chuen Kong Kevin Cheong
Research Collection Lee Kong Chian School Of Business
PurposeThe recent COVID-19 pandemic caused a severe economic downturn. Employees working in these organisations face employment uncertainty. The pandemic disrupted their daily routines, and it added a layer of complexity to the already resource-constrained environment. During these times, employees would conserve their resources to maintain competitiveness, one of which is knowledge hiding. While economic activities are resuming, the appearance of new variants could mean the transition towards endemicity could be put on hold. Hence, there is a need to rethink the behaviour of employees as they would have elevated levels of anxiety towards resuming daily work activities. Therefore, this study …

Scholars, government, and the public expect that legal enforcement should be an effective means to prevent a firm's future safety violation behavior in daily productions. However, the literature provides limited insights into whether safety regulation enforcement is effective in helping firms reduce future safety violations. Therefore, this study examines the relationship between occupational health and safety enforcement and a firm's future violation behavior. We carried out a regression analysis based on a panel sample of 2965 listed United States manufacturers with 4474 violation records issued by the Occupational Safety and Health Administration. We find limited effectiveness of enforcement. Our results …
A Queueing Model For Customer Rescheduling And No-Shows In Service Systems, Yue Tang, Houyuan Jiang, Jingui Xie, Zhichao Zheng
A Queueing Model For Customer Rescheduling And No-Shows In Service Systems, Yue Tang, Houyuan Jiang, Jingui Xie, Zhichao Zheng
Research Collection Lee Kong Chian School Of Business
We study an M/M/1/K queue where customers can reschedule their appointments. Rescheduled customers show up with higher probabilities, incurring lower no-show costs, but rescheduling also frees up slots that may not be filled later, leading to wasted service capacity and lower throughput. The system manager aims to minimize the long-run average cost by controlling rescheduling policies. We derive conditions under which rescheduling should be allowed for different scenarios depending on whether customers can reschedule only once or multiple times.

As information technology becomes integral to the products and services in a growing range of industries, there has been a corresponding surge of interest in understanding how firms can effectively formulate and execute digital business strategies. This fusion of IT within the business environment gives rise to a strategic tension between investing in digital artifacts for long-term value creation and exploiting them for short-term value appropriation. Further, relentless innovation and competitive pressures dictate that firms continually adapt these artifacts to changing market and technological conditions, but sustained profitability requires scalable architectures that can serve a large customer base and stable …

CRM refers to processes that involve interaction with end-users or customers. The increased emphasis on CRM today stems from changes in the business environment, availability of large amounts of data and advances in information technology.Outsourcing of customer relationship management (CRM) processes is rapidly becoming a competitive imperative for firms. However, there is little evidence on why the performance implications of outsourcing CRM processes differ so much across firms. In this study, the authors examine the impact of CRM outsourcing on shareholder value. The authors draw on insights from agency theory and the resource-based view of the firm in an international …
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 …
Introduction: Can We Bridge The Rigour-Relevance Gap?, Robin Fincham, Timothy Adrian Robert Clark
Introduction: Can We Bridge The Rigour-Relevance Gap?, Robin Fincham, Timothy Adrian Robert Clark
Research Collection Lee Kong Chian School Of Business
The following series of articles emanate from a session held at the first Journal of Management Studies Conference on the theme of ‘Beyond knowledge management: advancing the organizational knowledge research agenda’. The conference was concerned to advance academic understanding of this broad topic and in addition to reflect on the role of management scholars as creators, commodifiers and disseminators of management and organizational knowledge. The latter theme arose from debates in relation to the apparent marginality of business school academics in the production of management knowledge (Barley et al., 1988; Gibson and Tesone, 2001; Spell, 2001) and their consequent (in)ability …

An Integrated Decision– Making Approach For Improving European Air Traffic Management, Yael Gruksha-Cockayne, Bert De Reyck, Zeger Degraeve
Research Collection Lee Kong Chian School Of Business
We develop a multistakeholder, multicriteria decision-making framework for Eurocontrol, the European air traffic management organization, for evaluating and selecting operational improvements to the air traffic management system. The selected set of improvements will form the master plan of the Single European Sky initiative for harmonizing air traffic, in an effort to cope with the forecasted increase in air traffic, while maintaining safety, protecting the environment, and improving predictability and efficiency. The challenge is to select the set of enhancements such that the required performance targets are met and all key stakeholders are committed to the decisions. In this paper, we …

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 …

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 …
Vicious And Virtuous Circles In The Management Of Knowledge: The Case Of Infosys Technologies, Raghu Garud, Arun Kumaraswamy
Vicious And Virtuous Circles In The Management Of Knowledge: The Case Of Infosys Technologies, Raghu Garud, Arun Kumaraswamy
Research Collection Lee Kong Chian School Of Business
We adopt a systems perspective to explore the challenges that organizations face in harnessing knowledge. Such a perspective draws attention to mutually causal processes that have the potential to generate both vicious and virtuous circles. Based on a longitudinal study at Infosys Technologies, we conclude that knowledge management involves more than just the sponsorship of initiatives at and across different organizational levels. It also involves an active process of steering around and out of vicious circles that will inevitably emerge.
A Renewable-Resource Approach To Database Valuation, Xavier Dreze, Andre Bonfrer
A Renewable-Resource Approach To Database Valuation, Xavier Dreze, Andre Bonfrer
Research Collection Lee Kong Chian School Of Business
We demonstrate in this paper that firms should view customers in a database as a renewable resource when valuating them. Indeed, customer names flow in and out of the firm’s databases, and the goal of the firm is to optimize the overall customer acquisition/cultivation/attrition process. The renewable resource approach to the problem of maximizing the profits generated by a flow of customer names is more appropriate than the traditional Customer Lifetime Value (CLV) approach. We show that CLV underestimates the true value of names (by more than 400% in some cases) and leads to sub-optimal customer relationship management and acquisition …

A Note On The Paper “Resource-Constrained Project Scheduling: Notation, Classification, Models And Methods” By Brucker Et Al., Willy Herroelen, Erik Demeulemeester, Bert De Reyck
Research Collection Lee Kong Chian School Of Business
The great variety of project scheduling problems studied in the ever growing literature motivated the recent development of classification schemes. In a recent paper (European Journal of Operational Research 112 (1999) 3–41), Brucker et al. make the claim that, so far, no classification scheme exists which is compatible with what is commonly accepted in machine scheduling and introduce a new classification. In this note, we critically review major shortcomings of the suggested scheme which place heavy limitations on its potential use.
The Multi– Mode Resource– Constrained Project Scheduling Problem With Generalized Precedence Relations, Bert De Reyck, Willy Herroelen
The Multi– Mode Resource– Constrained Project Scheduling Problem With Generalized Precedence Relations, Bert De Reyck, Willy Herroelen
Research Collection Lee Kong Chian School Of Business
In this paper, we tackle the challenging problem of scheduling activities to minimize the project duration, in which the activities (a) are subject to generalized precedence relations, (b) require units of multiple renewable, non-renewable and doubly constrained resources for which a limited availability is imposed, and (c) can be performed in one of several different ways, reflected in multiple activity scenarios or modes. These multiple modes give rise to several kinds of tradeoffs (time/resource, time/cost and resource/resource trade-offs) which allow for a more effcient allocation and use of resources. We present a local search-based solution methodology which is able to …

Algorithms For Scheduling Projects With Generalized Precedence Relations, Bert De Reyck, Erik Demeulemeester, Willy Herroelen
Research Collection Lee Kong Chian School Of Business
The problem of scheduling projects under various types of resource constraints constitutes an important and challenging problem which has received increasing attention during the past several years. The bulk of the models and procedures designed for coping with these problem types aim at scheduling project activities to minimize the project duration subject to constant availability constraints on the required set of resources and precedence constraints that indicate that activities can only be started when all of their predecessors have already been finished. However, real-life project scheduling applications often involve more complicated types of precedence relations such as arbitrary minimal and …
A Classification Scheme For Project Scheduling Problems, Willy Herroelen, Erik Demeulemeester, Bert De Reyck
A Classification Scheme For Project Scheduling Problems, Willy Herroelen, Erik Demeulemeester, Bert De Reyck
Research Collection Lee Kong Chian School Of Business
The basic concern of scheduling is commonly described as the allocation of limited resources to tasks over time (Lawler et al. 1993, Pinedo 1995). The resources and tasks may take many forms. In project scheduling the tasks refer to the activities belonging to one or more projects. The execution of project activities may require the use of different types of resources (money, crews, equipment, …). The scheduling objectives may also take many forms (minimizing project duration, minimizing project costs, maximizing project revenues, optimizing due date performance,…). The result is a wide and steadily growing variety of problem types which motivates …
Local Search Methods For The Discrete Time/Resource Trade-Off Problem In Project Networks, Bert De Reyck, Erik Demeulemeester, Willy Herroelen
Local Search Methods For The Discrete Time/Resource Trade-Off Problem In Project Networks, Bert De Reyck, Erik Demeulemeester, Willy Herroelen
Research Collection Lee Kong Chian School Of Business
In this paper we consider the discrete time/resource trade-off problem in project networks. Given a project network consisting of nodes (activities) and arcs (technological precedence relations), in which the duration of the activities is a discrete, nonincreasing function of the amount of a single renewable resource committed to it, the discrete time/resource trade-off problem minimizes the project makespan subject to precedence constraints and a single renewable resource constraint. For each activity, a work content is specified such that all execution modes (duration/resource requirement pairs) for performing the activity are allowed as long as the product of the duration and the …
A Branch-And-Bound Procedure For The Resource-Constrained Project Scheduling Problem With Generalized Precedence Relations, Bert De Reyck, Willy Herroelen
A Branch-And-Bound Procedure For The Resource-Constrained Project Scheduling Problem With Generalized Precedence Relations, Bert De Reyck, Willy Herroelen
Research Collection Lee Kong Chian School Of Business
We present an optimal solution procedure for the resource-constrained project scheduling problem (RCPSP) with generalized precedence relations (RCPSP-GPR) with the objective of minimizing the project makespan. The RCPSPGPR extends the RCPSP to arbitrary minimal and maximal time lags between the starting and completion times of activities. The proposed procedure is suited for solving a general class of project scheduling problems and allows for arbitrary precedence constraints, activity ready times and deadlines, multiple renewable resource constraints with time-varying resource requirements and availabilities, several types of permissible and mandatory activity overlaps and multiple projects. It can be extended to other regular and …
New Computational Results On The Discrete Time/Cost Trade-Off Problem In Project Networks, Erik Demeulemeester, Bert De Reyck, Bram Foubert, Willy Herroelen
New Computational Results On The Discrete Time/Cost Trade-Off Problem In Project Networks, Erik Demeulemeester, Bert De Reyck, Bram Foubert, Willy Herroelen
Research Collection Lee Kong Chian School Of Business
We describe a new exact procedure for the discrete time/cost trade-off problem in deterministic activity-on-the-arc networks of the CPM type, where the duration of each activity is a discrete, nonincreasing function of the amount of a single resource (money) committed to it. The objective is to construct the complete and efficient time/cost profile over the set of feasible project durations. The procedure uses a horizon-varying approach based on the iterative optimal solution of the problem of minimising the sum of the resource use over all activities subject to the activity precedence constraints and a project deadline. This optimal solution is …

Resource-Constrained Project Scheduling: A Survey Of Recent Developments, Willy Herroelen, Bert De Reyck, Erik Demeulemeester
Research Collection Lee Kong Chian School Of Business
We review recent advances in dealing with the resource-constrained project scheduling problem using an efficient depth-first branch-and-bound procedure, elaborating on the branching scheme, bounding calculations and dominance rules, and discuss the potential of using truncated branch-and-bound. We derive conclusions from the research on optimal solution procedures for the basic problem and subsequently illustrate extensions to a rich and realistic variety of related problems involving activity preemption, the use of ready times and deadlines, variable resource requirements and availabilities, generalized precedence relations, time/cost, time/resource and resource/resource trade-offs and non-regular objective functions.
An Optimal Procedure For The Resource-Constrained Project Scheduling Problem With Discounted Cash Flows And Generalized Precedence Relations, Bert De Reyck, Willy Herroelen
An Optimal Procedure For The Resource-Constrained Project Scheduling Problem With Discounted Cash Flows And Generalized Precedence Relations, Bert De Reyck, Willy Herroelen
Research Collection Lee Kong Chian School Of Business
In this paper, we consider the resource-constrained project scheduling problem (RCPSP) with discounted cash flows and generalized precedence relations (RCPSPDC-GPR). The RCPSPDC-GPR extends the RCPSP to (a) arbitrary minimal and maximal time lags between the starting and completion times of activities and (b) the non-regular objective function of maximizing the net present value of the project with positive and/or negative cash flows associated with the activities. To the best of our knowledge, the literature on the RCPSPDC-GPR is completely void. We present a depth-first branch-and-bound algorithm in which the nodes in the search tree represent the original project network extended …

Resource-constrained project scheduling involves the scheduling of project activities subject to precedence and resource constraints in order to meet the objective(s) in the best possible way. The area covers a wide variety of problem types. The objective of this paper is to provide a survey of what we believe are the important recent developments in the area. Our main focus will be on the recent progress made in and the encouraging computational experience gained with the use of optimal solution procedures for the basic resource-constrained project scheduling problem (RCPSP) and important extensions. We illustrate how the branching rules, dominance and …
On The Use Of The Complexity Index As A Measure Of Complexity In Activity Networks, Bert De Reyck, Willy Herroelen
On The Use Of The Complexity Index As A Measure Of Complexity In Activity Networks, Bert De Reyck, Willy Herroelen
Research Collection Lee Kong Chian School Of Business
A large number of optimal and suboptimal procedures have been developed for solving combinatorial problems modeled as activity networks. The need to differentiate between easy and hard problem instances and the interest in isolating the fundamental factors that determine the computing effort required by these procedures, inspired a number of researchers to develop various complexity measures. In this paper we investigate the relation between the hardness of a problem instance and the topological structure of its underlying network, as measured by the complexity index. We demonstrate through a series of experiments that the complexity index, defined as the minimum number …

How To Arrive At Computer Integrated Manufacturing: A 3-Year Survey, Arnoud De Meyer
Research Collection Lee Kong Chian School Of Business
The large majority of modern production companies have at their disposal a multitude of computer systems. The immediate challenge for these companies consists of integrating these computer systems and databases. How will one arrive at this integration? On the basis of a questionnaire administered in 1985, 1986 and 1987 among a group of large European manufacturers, one comes to the conclusion that this integration is one of the immediate priorities for this group of companies. They do not intend to implement turnkey systems. but instead will integrate the different databases and computer systems gradually. One can see emerging islands of …
