TL;DR: A case study of a largely successful ERP implementation is presented and key factors, software selection steps, and implementation procedures critical to a successful implementation are discussed.

TL;DR: It is shown that the principal eigenvector is a necessary representation of the priorities derived from a positive reciprocal pairwise comparison judgment matrix A=(aij) when A is a small perturbation of a consistent matrix.

TL;DR: A novel taxonomy of the critical success factors in enterprise resource planning (ERP) implementation process is presented, based on a comprehensive analysis of ERP literature combining research studies and organisational experiences, which illustrates that ERP benefits are realised when a tight link is established between implementation approach and business process performance measures.

TL;DR: In this article, a classification of the decision problems that arise at container terminals is presented, and a discussion of the models used to solve the problems is given. But the authors do not discuss the general conclusions and subjects for further research.

TL;DR: In this paper, a general decision rule is introduced that avoids variance amplification and succeeds in generating smooth ordering patterns, even when demand has to be forecasted, regardless of the forecasting method used.

TL;DR: This article traces the evolution of ambulance location and relocation models proposed over the past 30 years and describes the models classified in two main categories: deterministic and dynamic.

TL;DR: Results from a Delphi study on the future impact of enterprise resource planning (ERP) systems on supply chain management (SCM) are presented and key limitations of current ERP systems in providing effective SCM support emerge.

TL;DR: A model based on time-dependent travel speeds which satisfies the “first-in–first-out” property is presented and it is shown that the time- dependent model provides substantial improvements over a modelbased on fixed travel times.

TL;DR: New simulated annealing algorithms for the resource-constrained project scheduling problem (RCPSP) and its multiple mode version (MRCPSp) are described and the efficiency of both adaptations are proved, currently among the most competitive algorithms for these problems.

TL;DR: This paper formalizes this inconsistency measure, hereafter called the Geometric Consistency Index (GCI), and provides the thresholds associated with it, which allow us an interpretation of the inconsistency tolerance level analogous to that proposed by Saaty.

TL;DR: A brief overview, in the form of a bibliographic survey, of the many models and methodologies available to solve the nurse rostering problem is presented.

TL;DR: This paper discusses reverse distribution, and proposes a mathematical programming model for a version of this problem that complements a heuristic concentration procedure, where sub-problems with reduced sets of decision variables are iteratively solved to optimality.

TL;DR: Key differences in the approaches used by companies that managed their implementations on-time and/or on/under-budget versus the ones that did not are identified using data collected through a survey of US manufacturing companies that have implemented ERP systems.

TL;DR: The study shows that the mean efficiency score of Indian banks compares well with the worldmean efficiency score and the efficiency of private sector commercial banks as a group is, paradoxically lower than that of public sector banks and foreign banks in India.

TL;DR: There is a significant and positive relationship between the manager’s motives for adopting ISO 9000 certification and business performance and those organizations that pursue certification willingly and positively across a broad spread of objectives are more likely to report improved organizational performance.

TL;DR: The paper at hand examines, based on a critical literature review, the actual EM discussion and calls for more supply chain management research within this field.

TL;DR: The bibliography provides an overview of the literature on “MCDM combined with finance,” shows how contributions to the area have come from all over the world, facilitates access to the entirety of this heretofore fragmented literature, and underscores the often multiple criterion nature of many problems in finance.

TL;DR: The PLOT (Production, Logistics, Outbound, Transportation) design system is described, which generates globally feasible, near optimal distribution system design and utilization strategies utilizing the simulated annealing (SA) methodology.

TL;DR: This paper compares the efficacy of five current, and promising, methods that can be used to deal with missing data and concludes that MI, because of its theoretical and distributional underpinnings, is probably most promising for future applications in this field.

TL;DR: A hierarchical analytic hierarchy process (AHP) and data envelopment analysis (DEA) approach to solve a plant layout design problem and empirical illustrations from a practical case study illustrated the effectiveness of the proposed methodology.

TL;DR: The literature on real-time vehicle routing is still disorganized and some issues that have not received attention so far are highlighted in this paper, where a particular emphasis is put on parallel computing strategies.

TL;DR: Some experiences of an ERP implementation in a water corporation are described and some of the intricacies during the planning and implementation stages that may occur in any company in any part of the world are revealed.

TL;DR: An hybrid method combining two algorithms is proposed for the global optimization of multiminima functions, called continuous hybrid algorithm (CHA), performing the exploration with a GA, and the exploitation with a Nelder–Mead SS, and compared the results to the ones supplied by other competitive methods.

TL;DR: In this paper, the authors describe the application of a simulated annealing approach to the solution of a complex portfolio selection model, which is a mixed integer quadratic programming problem which arises when Markowitz' classical mean-variance model is enriched with additional realistic constraints.

TL;DR: An evolutionary heuristic (population heuristic) is presented for the solution of the index tracking problem and Computational results are presented for five data sets drawn from major world markets.

TL;DR: This work extends the setting studied so far to the case of job-dependent learning curves, that is, it allows the learning in the production process of some jobs to be faster than that of others, and shows that in the new, possibly more realistic setting, the problems of makespan and total flow-time minimization on a single machine, a due-date assignment problem and total flowspan on unrelated parallel machines remain polynomially solvable.

TL;DR: An overview of some fuzzy set-based approaches to scheduling is proposed,phasizing two distinct uses of fuzzy sets: representing preference profiles and modelling uncertainty distributions, and a possibility-theoretic counterpart of PERT.

TL;DR: It is shown that data envelopment analysis (DEA) can be viewed as maximising the average efficiency of the decision-making units (DMUs) in an organisation and models for allocating fixed costs and input resources are presented.

TL;DR: It is usual to rank the participant countries in the Olympic Games in accordance with the number of medals they have won, but an alternative ranking is suggested in this paper, based on each country’s ability to win medals in relation to its available resources.

TL;DR: Despite extensive time, money and effort, length of time with the firm and position had a greater impact on attitudes toward ERP capabilities, value, acceptance and timing than high levels of pre-implementation involvement.
