TL;DR: A comparative analysis of the multiple criteria decision making methods VIKOR and TOPSIS is illustrated with a numerical example, showing their similarity and some differences.

3,563 citations


Journal ArticleDOI
TL;DR: A review of staff scheduling and rostering, an area that has become increasingly important as business becomes more service oriented and cost conscious in a global environment, and the models and algorithms that have been reported in the literature for their solution.

1,238 citations


Journal ArticleDOI
TL;DR: The literature available on IT in SCM has been classified using suitable criteria and then critically reviewed to develop a framework for studying the applications of IT inSCM and some future research directions are indicated.

1,157 citations


Journal ArticleDOI
TL;DR: A new characterization of the consistency property defined by the additive transitivity property of the fuzzy preference Relations is presented and a method for constructing consistent fuzzy preference relations from a set of n preference data is proposed.

929 citations


Journal ArticleDOI
TL;DR: Recommendations are formulated to integrate into PROMETHEE a number of useful AHP features, especially as regards the design of the decision-making hierarchy, so that operational synergies can be achieved in MCA.

756 citations


Journal ArticleDOI
TL;DR: The main argument developed here is the proposal of the concept of social multi-criteria evaluation (SMCE) as a possible useful framework for the application of social choice to the difficult policy problems of the authors' millennium, where “facts are uncertain, values in dispute, stakes high and decisions urgent”.

653 citations


Journal ArticleDOI
TL;DR: The application links SWOT analysis to resource-based planning, illustrates it as an iterative rather than a linear process and embeds it within the overall planning process.

652 citations


Journal ArticleDOI
TL;DR: A review and evaluation of the use of problem structuring methods (PSMs) in practice and some possible future developments are suggested, especially through productive interactions with similar or related practices.

611 citations


Journal ArticleDOI
TL;DR: A framework is provided to illustrate how models for this class of machine scheduling problems have been generalized from the classical scheduling theory, and a complexity boundary is presented for each model.

603 citations


Journal ArticleDOI
TL;DR: Two different approaches are applied to the problem of measuring the efficiency of 24 power plants in a European country, treating pollutants as the inputs in the sense that they wish to increase desirable outputs and decrease pollutants and inputs.

569 citations


Journal ArticleDOI
TL;DR: How cognitive maps might be analyzed for the purpose of structuring problems or issues and what the various analysis methods imply for an operational research practitioner when helping a client work on a ‘‘messy’’ issue or problem are suggested.

Journal ArticleDOI
TL;DR: It is argued that intermodal freight transportation research is emerging as a new transportation research application field, that it still is in a pre-paradigmatic phase, and that it needs a different type of models than those applicated to uni-modal transport.

Journal ArticleDOI
TL;DR: This work suggests an alternative approach which allows us to explicitly model a joint environmental technology and gauge performance in terms of increased good output and decreased undesirable output by adopting a directional distance function which may be estimated using the usual linear programming techniques employed in DEA.

Journal ArticleDOI
TL;DR: This work presents a comparison of 25 methods, ranging from the classical Johnson's algorithm or dispatching rules to the most recent metaheuristics, including tabu search, simulated annealing, genetic algorithms, iterated local search and hybrid techniques, for the well-known permutation flowshop problem with the makespan criterion.

Journal ArticleDOI
TL;DR: The paper reviews emerging patterns in supply chain integration and explores the relationship between the emerging patterns and attainment of competitive objectives and validate the proposed conceptual model and lend credence to current thinking that supply chain Integration is a vital tool for competitive advantage.

Journal ArticleDOI
TL;DR: The findings suggest that developing PMSs should to a large extent be understood as a co-ordination effort rather than a design effort and the lessons learned cannot have universal validity, but may be helpful in similar kinds of initiatives.

Journal ArticleDOI
TL;DR: This study proposes a branch and bound (B & B) method to obtain the optimal solution of the QC scheduling problem and a heuristic search algorithm, called greedy randomized adaptive search procedure (GRASP), to overcome the computational difficulty of the B & B method.

Journal ArticleDOI
TL;DR: This paper examines the beneficial impact of information sharing in multi-echelon supply chains and introduces acontrolengineering based measure to quantify the variance amplification (bullwhip) or variance reduction of supply chain replenishment rules.

Journal ArticleDOI
TL;DR: These findings suggest that: (1) demographic characteristics, environmental changes and stimulating ‘interactive and continuous’ relationships with customers are of major concern when considering retention; (2) customer behaviour predictors only have a limited impact on attrition in terms of total products owned as well as the interpurchase time.

Journal ArticleDOI
TL;DR: This paper surveys the main results of the multidimensional 0–1 knapsack problem and focuses on the theoretical properties as well as approximate or exact solutions of this special 0-1 program.

Journal ArticleDOI
TL;DR: A comparison of solutions yielded by the proposed ant-colony algorithms with the best heuristic solutions known for the benchmark problems, as published in an extensive study by Liu and Reeves is carried out.

Journal ArticleDOI
TL;DR: Return to scale (RTS) in data envelopment analysis (DEA) for each of the presently available types of models is discussed for each type of model and relations between the results for the different models are established.

Journal ArticleDOI
TL;DR: An objective framework for effective supplier sourcing is proposed, which considers multiple strategic and operational factors in the evaluation process and assists managers in identifying candidates for strategic long-term partnerships, supplier development programs, and pruning.

Journal ArticleDOI
TL;DR: Numerical results using customized local search, simulated annealing, tabu search and genetic algorithm heuristics show that problems of practically relevant size can be solved quickly.

Journal ArticleDOI
TL;DR: The use of cognitive mapping techniques for policy analysis in the UK Home Office Prison Department is reported, used for the collation, comparison and analysis of the views of many experts in relation to a major policy issue.

Journal ArticleDOI
TL;DR: Using data from 256 US transit systems over a five-year period, the results indicate that efficiency and effectiveness are positively related and imply that the magnitude of scale economies depends on the output specification.

Journal ArticleDOI
TL;DR: This paper examines scheduling in flexible flow lines with sequence-dependent setup times to minimize makespan, and finds an application of the Random Keys Genetic Algorithm to be very effective for the problems examined.

Journal ArticleDOI
TL;DR: A proof of NP-hardness and a heuristic with worst-case analysis is provided for the problem in which jobs are processed on a single machine and delivered by a single vehicle to one customer area and another heuristic is provided that is 100% error bound.

Journal ArticleDOI
TL;DR: A novel 0–1 integer programming formulation of the university timetabling problem is presented and it is shown that this model is solvable by existing software tools with IP solvers, even for large departments.

Journal ArticleDOI
TL;DR: A new tabu search algorithm is presented that explores the structure of this type of problem and its performance is compared with another heuristic designed for the same purpose, which has been published recently.
