The growing number of services that can meet the users’ functional requirements, inspired many researchers to provide some approaches to rank and select the best possible services regarding their quality of service (QoS) and users’ preferences. Considering various criteria which should be considered in the service selection process, multi-criteria decision making (MCDM) techniques have been vastly applied to help a decision-maker in determining the weight of each QoS factor and ranking the services provided by different service providers. This paper provides an extensive investigation of the state of the art MCDM-based service selection schemes proposed in the literature. It provides the required background knowledge and puts forward a taxonomy of the investigated service selection schemes regarding their applied MCDM methods. Also, it describes how the MCDM methods are adapted by the studied schemes, which datasets and QoS criteria are employed by each system, and which factors and environments are utilized to evaluate the service selection schemes. Finally, the concluding remarks are provided, and directions for future studies are highlighted.

使用多标准决策制定服务选择：综合概述

能够满足用户功能需求的服务数量不断增加，激发了许多研究人员提供一些方法来根据服务质量 (QoS) 和用户偏好对可能的最佳服务进行排序和选择。考虑到在服务选择过程中应考虑的各种标准，多标准决策 (MCDM) 技术已被广泛应用于帮助决策者确定每个 QoS 因素的权重并对不同服务提供商提供的服务进行排序。本文对文献中提出的最先进的基于 MCDM 的服务选择方案进行了广泛的调查。它提供了所需的背景知识，并就其应用的 MCDM 方法提出了所调查的服务选择方案的分类。还，它描述了 MCDM 方法如何适应所研究的方案，每个系统采用哪些数据集和 QoS 标准，以及利用哪些因素和环境来评估服务选择方案。最后，提供了结束语，并强调了未来的研究方向。
