Journal ArticleDOI
TL;DR: An extensive review of the scheduling literature on models with setup times (costs) from then to date covering more than 300 papers is provided, which classifies scheduling problems into those with batching and non-batching considerations, and with sequence-independent and sequence-dependent setup times.

Journal ArticleDOI
TL;DR: This paper shows how ACO, which was initially developed to be a metaheuristic for combinatorial optimization, can be adapted to continuous optimization without any major conceptual change to its structure, and compares the results with those reported in the literature for other continuous optimization methods.

1,238 citations


Journal ArticleDOI
TL;DR: The relational model developed in this paper is more reliable in measuring the efficiencies and consequently is capable of identifying the causes of inefficiency more accurately.

1,112 citations


Journal ArticleDOI
TL;DR: A literature survey on the application of data envelopment analysis (DEA) to E&E studies is presented and an introduction to the most widely used DEA techniques is introduced.

Journal ArticleDOI
William Ho1
TL;DR: This research provides evidence that the integrated AHPs are better than the stand-alone AHP, but also aids the researchers and decision makers in applying the integratedAHPs effectively.

993 citations


Journal ArticleDOI
TL;DR: This paper classifies and surveys network hub location models, includes some recent trends on hub location and provides a synthesis of the literature.

830 citations


Journal ArticleDOI
TL;DR: It is found that the extent analysis method cannot estimate the true weights from a fuzzy comparison matrix and has led to quite a number of misapplications in the literature.

628 citations


Journal ArticleDOI
TL;DR: The questions why and when learning effects in scheduling environments might occur and should be regarded from a planning perspective are discussed.

614 citations


Journal ArticleDOI
TL;DR: The AHP appears to be a promising support tool for shared decision making between patient and doctor, evaluation and selection of therapies and treatments, and the evaluation of health care technologies and policies.

512 citations


Journal ArticleDOI
TL;DR: In this article, a survey of cooperative game theory applications to supply chain management is presented, focusing on two important aspects of cooperative games: profit allocation and stability, and an exhaustive survey of commonly used stability concepts is presented.

Journal ArticleDOI
TL;DR: The results suggest that the manufacturer is likely to be better off in the dual channel than in the single channel when the retailer’s marginal cost is high and the wholesale price, consumer valuation and the demand variability are low.

Journal ArticleDOI
TL;DR: This review provides a systematic overview of managerial planning tasks and reviews corresponding quantitative models to enhance the understanding of multi-channel e-fulfillment and to identify gaps between relevant managerial issues and academic literature, thereby indicating directions for future research.

Journal ArticleDOI
TL;DR: Distinguishing necessary and possible consequences of preference information on the complete set of actions, UTAGMS answers questions of robustness analysis and can support the decision maker when his/her preference statements cannot be represented in terms of an additive value function.

Journal ArticleDOI
TL;DR: The existing research related to multi-objective optimization in routing problems is surveyed, in terms of their definitions, their objectives, and the multi- objective algorithms proposed for solving them.

Journal ArticleDOI
TL;DR: This work presents a new fuzzy multiple attributes decision-making approach, i.e., fuzzy simple additive weighting system (FSAWS), for solving facility location selection problems by using objective/subjective attributes under group decision- making (GDM) conditions.

Journal ArticleDOI
TL;DR: The findings suggest that while recurrent neural networks and support vector machines show the best performance, their forecasting accuracy was not statistically significantly better than that of the regression model.

Journal ArticleDOI
TL;DR: This paper provides an annotated bibliography of recent papers in two branches of discrete location theory and modeling related to the median and plant location models and to center and covering models.

Journal ArticleDOI
TL;DR: The results suggest that whilst selection of the MCA technique is important more emphasis is needed on the initial structuring of the decision problem, which involves choosing criteria and decision options.

Journal ArticleDOI
TL;DR: It is shown that when dealing with time constraints, like hard delivery time windows for customers, the known solutions for the classic case become unfeasible and the degree of unfeasibility increases with the variability of traffic conditions, while if no hard time constraints are present, the classic solutions become suboptimal.

Journal ArticleDOI
TL;DR: Two new IG algorithms are proposed for a complex flowshop problem that results from the consideration of sequence dependent setup times on machines, a characteristic that is often found in industrial settings.

Journal ArticleDOI
TL;DR: A transformation technique is studied which enables the proposed weighted linear program for the multi-criteria supplier selection problem to be solved without an optimizer.

Journal ArticleDOI
TL;DR: Numerical results show that important gains can be realized by using a stochastic OR planning model and a Monte Carlo optimization method combining Monte Carlo simulation and Mixed Integer Programming is proposed.

Journal ArticleDOI
TL;DR: This paper presents a genetic algorithm for the resource constrained multi-project scheduling problem based on random keys that builds parameterized active schedules based on priorities, delay times, and release dates defined by the genetic algorithm.

Journal ArticleDOI
TL;DR: A new surgical case scheduling approach is proposed which uses a novel extension of the Job Shop scheduling problem called multi-mode blocking job shop (MMBJS) as a mixed integer linear programming (MILP) problem and the use of the MMBJS model for scheduling elective and add-on cases is discussed.

Journal ArticleDOI
TL;DR: The main approaches to capacity identification proposed in the literature are reviewed and their advantages and inconveniences are discussed and their application is illustrated on a detailed example.

Journal ArticleDOI
TL;DR: It is shown that by combining advanced optimization techniques with extensive historical statistical records on surgery durations can significantly improve the operating room department utilization, and frees a lot of operating room capacity, which may be used to perform additional surgeries.

Journal ArticleDOI
TL;DR: The meaning of the priority vector derived from the principal eigenvalue method used in AHP is addressed, and the role of AHP’s consistency ratio is analysed.

Journal ArticleDOI
TL;DR: The objective of this research is to find the best truck docking or scheduling sequence for both inbound and outbound trucks to minimize total operation time when a temporary storage buffer to hold items temporarily is located at the shipping dock.

Journal ArticleDOI
TL;DR: In this paper, a method is suggested to solve the nonlinear interval number programming problem with uncertain coefficients both in nonlinear objective function and nonlinear constraints, based on an order relation of interval number.

Journal ArticleDOI
TL;DR: An optimization procedure which specializes in solving a wide variety of optimization problems, designed as a generic multi-objective, multi-optima optimizer which automatically degenerates to efficient algorithms for solving other simpler optimization problems.
