【摘要】：云计算作为一种新兴的网络计算服务模式,它的出现及广泛应用,极大地方便了用户访问和使用各种网络信息资源和服务,使其逐步发展为互联网领域的一个研究热点。随着云计算技术的普及和云服务应用的推广,市场上出现了许多不同的云服务提供商及其相关产品,这对用户在进行选择时造成了很大困扰,需要一种新的选择框架来指导其选择过程。同时云计算作为一个新兴的技术,技术还不够成熟,人们对其也并不完全了解,这导致了用户在引入云服务和选择提供商的过程中存在着很大的无知和不确定性,这就需要一种科学的、合理的方法来解决这一问题,而不确定性问题是在决策实际过程中常见的问题,现在面对各种不确定性问题,主要有两种不同的主流方法：绝对基偏好决策方法,和相对基偏好决策方法,其中相对基偏好决策方法又叫做方案两两比较方法。现有的方案两两比较方法一般构建单等级上的比较关系,且不能同时表达优于、劣于、无差异和不确定四种关系,这就急需一种更合理、更灵活的决策方法来解决更复杂的应用场景。本文围绕基于多等级方案成对比较方法的云服务选择相关问题,首先针对现有云计算及其服务做了简要介绍,之后对多家云服务提供商进行了分类的详细介绍,来扩充云服务提供商选择的方案集,并提出了云服务提供商选择应用框架。之后对方案选择的决策方法又进行了理论研究,通过设定识别框架和等级得分值来更合理地描绘现实决策的不确定情况,之后通过引入区间值、可能度等相关概念,设计了完整的多等级方案成对比较方法,并介绍了方法的基本步骤。最后针对现实中企业引入云服务选择提供商的问题,通过云服务提供商选择框架和方案成对比较方法,依据现有的方案集,提出了以供应商评价为基础的基于多等级的云服务选择流程,并以制造领域为背景进行了实际应用。
[Abstract]:Cloud computing as a new network computing service mode, its emergence and wide application greatly facilitate users to access and use all kinds of network information resources and services, making it gradually become a research hotspot in the Internet field. With the popularity of cloud computing technology and the promotion of cloud service applications, many different cloud providers and related products have appeared on the market, which has caused great distress to users when choosing, and a new selection framework is needed to guide their selection process. At the same time, cloud computing as an emerging technology, the technology is not mature enough, the people are not fully understood, the user has great ignorance and uncertainty in the process of the introduction of cloud services and the choice of providers, which requires one kind of method is scientific and reasonable to solve this problem. But uncertainty is common in the actual process of decision problem, now face a variety of uncertainties, there are two kinds of main methods: absolute and relative preference, preference based decision method, decision making method and relative preference based scheme called 22 comparison method. The existing scheme 22 comparison method generally constructs a comparison relationship on single level, and can not express four relationships at the same time, which is superior, inferior, indifference and uncertainty. So it is urgent for a more reasonable and flexible decision-making method to solve more complex application scenarios. Based on cloud service selection problems of multi level scheme based on the method of paired comparison, first made a brief introduction to the existing cloud computing and service, after a number of cloud service providers for detailed classification, to expand the cloud service provider selection scheme set, and proposes a cloud service provider application framework. After the scheme selection decision making method and the theoretical study, by setting the grade score recognition framework and to better depict real decision-making uncertainty, then by introducing the interval value, possibility degree and other related concepts, design a paired comparison method for multi grade complete program, and introduces the basic steps of the method. According to the choice of cloud service providers to introduce real business problems, through the comparison method of cloud service provider selection framework and program pairs, on the basis of the existing schemes, put forward to the supplier evaluation based selection process of multi class based cloud services, and practical application in manufacturing field as the background.
