Many organisations are evaluating their supply chains because they are perceived to be an area for both cost cutting and increasing competitiveness. The objective is apparently very simple; optimise the supply chain via effective and efficient operating practices. This paper will demonstrate via the statistical analysis of 32 industrial case studies that the route to this desired fully integrated,...
The purpose of this paper is to analyze manufacturing networks and supply chains from an operations strategy perspective. These two areas have traditionally been treated as separate research tracks, but with the ongoing globalization of markets and operations there is a need to integrate these complementary disciplines to study networks of facilities. In this paper we examine the two research areas...
In this paper we consider the vehicle routing problem with soft time window constraints (VRPSTW), in which vehicles are allowed to service customers before and after the earliest and latest time window bounds, respectively. This relaxation comes at the expense of appropriate penalties that reflect the effect that time window violations have on the customers' satisfaction. The problem is of particular...
Strategic investments such as flexible manufacturing technology yield benefits to a company beyond the immediate cash flows. These strategic benefits can be captured, to some degree, using real option valuation techniques. However, real option models presume these can be identified and evaluated at an early stage in the investment process. In this paper, the authors argue real option value is often...
The collaborative integration with global third party logistics (3PL) to execute physical distribution dictates the success of any global supply chain (GSC) application. In an overall effort to minimize the system-wide cost, global 3PL can apply various consolidation policies to maximize the utilization of expensive transportation such as aircraft. Freight consolidation has received considerable attention...
This paper sets out to explore the quality initiatives of various industries and examine the links between quality management implementation and quality outcomes. We use the scenario in Hong Kong as a first step in addressing these research inquiries. Using Black and Porter's instrument (Decision Sci. 27 (1996) 1) and the various perceived performance measures representing quality management implementation...
This paper examines the problem of how to establish an incentive scheme to furnish reliable and truthful information in Supply Chains. In the current discussion information is typically assumed to be perfect and Supply Chain Partners are presumed to behave altruistically. In our judgement these assumptions are far from realistic. In consequence we assume that opportunistic behavior can emerge and...
Organizations would like to capture and merge the perceptions of key individuals into an organizational memory. Various cognitive mapping approaches have been used to identify and capture these perceptions. However, merging the cognitive maps of individuals into a collective cognitive map to represent the shared perceptions has been problematic. Due to the merging problems, the creation of collective...
This paper describes a workshop-based process bringing together for the first time two approaches-immersive drama and whole systems thinking-which was designed to test the extent to which health service systems are able to recognise and remedy emergent management and clinical problems. The workshop provided participating health service managers with insights into, and pointers to improvements in,...
We investigate the concept of productivity in retailing. In the literature, there are unresolved issues concerning the construct of retail output and measurement methodologies. In accordance with recently developed theory, we define the output of the retail firm as a set of explicitly priced market goods accompanied by distribution services that are implicitly priced. We operationalise these services,...
This is one of a very few longitudinal research studies of the link between TQM implementation and successful outcomes. The paper reports on perceived TQM success for a cohort of 109 firms over a 5-year period. Some 42 firms, predominantly small in size, had discontinued with TQM, while the remaining 67 firms reported varying degrees of success. The data suggests that the size of firm, the nature...
The single machine tardiness problem is considered. We clarify and correct an earlier result related to the Modified Due Date (MDD) Rule of Baker and Bertrand and show that a heuristic does not always satisfy an optimal sequence. However, we present some interesting special cases of optimal sequences that do satisfy the MDD Rule. We believe this note is important because the MDD Rule is still considered...
A number of credit-scoring models that accurately classify consumer loan applications have been developed to aid traditional judgmental methods. This study compares the performance of multiple discriminant analysis (MDA) and neural networks in identifying potential loan. The neural network models consistently perform better than the MDA models in identifying potential problem loans. To alleviate the...
This study investigates JIT implementation practices and performance in manufacturing and service organizations in the US. Literature related to JIT usage and performance in both sectors is reviewed. A field study is then conducted to investigate the actual implementation experiences of a selected group of service and manufacturing users of JIT. Our findings from the literature and the field study...
The effective deployment of technology within an organizational context is of integral concern to fields associated with the management sciences. While there has been significant study of technology effectiveness, it is often piece-meal as diverse models are hypothesized and empirically tested. This paper attempts to examine the models purporting to study the fundamental question of effective use...
The Bullwhip Problem in supply chains is first outlined. A discrete control theory model of a generic model of a replenishment rule is presented. From this model, an analytical expression for bullwhip is derived that is directly equivalent to the common statistical measure often used in simulation, statistical and empirical studies to quantify the bullwhip effect. This analytical expression clearly...
In this paper, we study a stochastic sequential ordering problem, where a set of jobs must be scheduled on a single machine. The jobs have stochastic processing times and verify certain precedence relations. For each job, there also exists a time window characterized by the release time and the due date. The jobs must be processed into the time-windows. For all the sequences of jobs that verify the...
The literature on individual and organizational resilience is reviewed. A theoretical model is developed to address the lack of specific research and theory concerning stress and resilience in the information system field as specified by Thong and Yap (Omega 28 (2000) 681). Specifically, in order to understand organizational resilience in the information system field, the proposed model integrates...
Enterprise Resource Planning (ERP) systems have experienced a phenomenal growth in the last 5 years and at present they are pervasive in the US manufacturing sector. This paper describes an attempt to chronicle this phenomenon through a series of case studies and an extensive survey. Manufacturing companies ranging in size from a few million dollars in annual revenues to over a hundred billion dollars...
