TL;DR: A literature review of the applications of Analytic Hierarchy Process, which aims to provide a ready reference on AHP, and act as an informative summary kit for the researchers and practitioners for their future work.

TL;DR: The literature is surveyed to identify potential research directions in disaster operations, discuss relevant issues, and provide a starting point for interested researchers.

TL;DR: The developments in GALBP research is surveyed in order to describe and solve more realistic generalized problems (GALBP) and to survey the developments in assembly line balancing research.

TL;DR: This paper gives an up-to-date and comprehensive survey of SALBP research with a special emphasis on recent outstanding and guiding contributions to the field.

TL;DR: The paper explores the relationship among lead-time, cost, quality, and service level and the leanness and agility of a case supply chain in fast moving consumer goods business and the justification of the framework is presented, which encapsulates the market sensitiveness, process integration, information driver and flexibility measures of supply chain performance.

TL;DR: It is concluded that most models can be applied for design problems at manufacturing centres and new analytical and simulation models need to be developed for large AGV systems to overcome large computation times, NP-completeness, congestion, deadlocks and delays in the system and finite planning horizons.

TL;DR: In this paper, a survey of heuristics for resource-constrained project scheduling problem (RCPSP) is presented, which provides an update of our survey which was published in 2000.

TL;DR: In this paper, an integrated framework based on fuzzy-QFD and a fuzzy optimization model is proposed to determine the product technical requirements (PTRs) to be considered in designing a product.

TL;DR: Rank preservation and reversal are important subjects in multi-criteria decision-making particularly if a theory uses only one of two ways of creating priorities: rating alternatives one at a time with respect to an ideal or standard, or comparing them in pairs.

TL;DR: The ER approach will be used to aggregate multiple environmental factors, resulting in an aggregated distributed assessment for each alternative policy, and a new analytical ER algorithm will be investigated which provides a means for using the ER approach in decision situations where an explicit ER aggregation function is needed.

TL;DR: A mixed integer programming model is developed and an efficient heuristic solution procedure is provided for this supply chain system problem to select the optimum numbers, locations and capacities of plants and warehouses to open so that all customer demand is satisfied at minimum total costs of the distribution network.

TL;DR: A unified model is developed that is capable of handling most variants of the Vehicle Routing Problem with Backhauls and it has improved the best known solution for 227 of these.

TL;DR: This article examined the fit of total quality management (TQM) practices in mediating the relationship between organization strategy and organization performance and concluded that TQM needs to be complemented by other resources to more effectively realize the strategy in achieving a high level of performance, particularly innovation.

TL;DR: This paper aims to provide a metaheuristic, in the form of a genetic algorithm, to a complex generalized flowshop scheduling problem that results from the addition of unrelated parallel machines at each stage, sequence dependent setup times and machine eligibility.

TL;DR: The health care system in Sweden and many other countries is facing increasing costs, the major reason is the changing age distribution of the population with more elderly people in need of support.

TL;DR: This paper provides the main principles and ideas of scatter search and its generalized form path relinking and describes a basic design to give the reader the tools to create relatively simple implementations.

TL;DR: A new, adaptive scheme to generate appropriate constraint values during the run is proposed, and it is proved that––independent of the problem or the problem size––the time complexity of the new scheme is O(km−1), where k is thenumber of Pareto-optimal solutions to be found and m the number of objectives.

TL;DR: In this paper, the authors present a review on the design and control of automated guided vehicle systems, including guide-path design, determining vehicle requirements, vehicle scheduling, idle-vehicle positioning, battery management, vehicle routing and deadlock resolution.

TL;DR: This article enhances the ILS algorithm using acceptance criteria that allow moves to worse local optima and proposes population-based ILS extensions and shows their excellent performance when compared to other state-of-the-art algorithms for the QAP.

TL;DR: A state-of-the-art of a particular planning problem, the Single Item Lot Sizing Problem, is given for its uncapacitated and capacitated versions.

TL;DR: This paper combines elements from scatter search, a generic population-based evolutionary search method, and a recently introduced heuristic method for the optimisation of unconstrained continuous functions based on an analogy with electromagnetism theory to provide near-optimal heuristic solutions for resource-constrained project scheduling.

TL;DR: An effective heuristic that combines a genetic algorithm with a local tour improvement heuristic for the generalized traveling salesman problem, which is competitive with other heuristics published to date in both solution quality and computation time.

TL;DR: In this article, a utility-based grade match method is proposed to transform both numerical data and qualitative (fuzzy) assessment information of various formats into the fuzzy belief structure, leading to a fuzzy belief decision matrix.

TL;DR: The novel method requires few control variables, is relatively easy to implement and use, effective, and efficient, which makes it an attractive and widely applicable approach for solving practical engineering problems.

TL;DR: When data are contaminated with outliers, the use of the super-efficiency model to identify and remove outliers results in more accurate efficiency estimates than those obtained from the conventional DEA estimation model.

TL;DR: Research results indicate that there is still much room for enterprises to improve competitiveness in situations of confining score ranges of technological innovation capability and competitiveness.

TL;DR: A brief glimpse into the evolution of flowshop scheduling problems and possible approaches for their solution over the last fifty years is provided.

TL;DR: It is found that the direct channel has a negative impact on the retailer’s performance, and, under some conditions, the manufacturer and the whole supply chain are better off.

TL;DR: This paper reviews literature dealing with buyer vendor coordination models that have used quantity discount as coordination mechanism under deterministic environment and classified the various models.

TL;DR: The peculiarities of establishing a closed-loop supply chain (CLSC) are presented, based on an example considering the end-of-life vehicle (ELV) treatment in Germany, and results of several CLSC scenarios are discussed based on real case data, depicting measures from German ELV stakeholders.
