The popularity of cloud computing and IaaS has spawned numerous cloud service providers which offer various cloud services, including IaaS, to cloud users. These services vary considerably in terms of their performance and cost and the selection of a suitable cloud service becomes a complex decision making issue for a cloud service user. Furthermore, the cloud services have several attributes all...
In order to evaluate the operation conditions of operating logistics parks systematically, and promote their development, this article build an integrated evaluation system using analytic hierarchy process. This system include 4 Classes of guidelines layer indicators which reflect the operating basis, operating capacity, operating efficiency and operating potential, as well as 66 index layers indicators,...
Traditional DEA models can' t be directly used in ranking because of the flaw of weight flexibility. The current paper proposes a common weight deriving technique based on standard samples. The standard samples include those decision-making units with all-known high performance. In out proposed approach the standard samples determine the common weight which is used by all ordinary those decision-making...
This paper sets up a comprehensive assessment system model for university teachers, which includes three sides such as knowledge skill and quality and fourteen indicators. Then, the weight coefficients of indexes are determined by analytic hierarchy process (AHP), and outstanding the emphasis on assessment of university teachers. So it provides a good reference to to assess university teachers comprehensively.
A game model for solving multiple attribute decision making without weight information is proposed. In this model, each attribute is a player whose strategy is to choose a value to endow its attribute weight, and whose utility is matching degree between alternative order produced by decision making and alternative order produced by magnitude of attribute. The Nash equilibrium solution is obtained...
Information systems project selection is a multi-criteria decision-making (MCDM) problem. This work develops a fuzzy approach based on the technique for order performance by similarity to ideal solution (TOPSIS), to choose optimal information system in a fuzzy environment where the data are often incomplete or not so deterministic. In this paper, the importance weight of each criterion and the rating...
The individual preferences for gains, losses, and uncertain events, which are first proposed by prospect theory, are rarely considered in current MADM methods. To solve this problem, a MADM alternative ranking approach under uncertainty is presented. The presented approach proposes a method for eliciting individual preferences for gains, losses and uncertain events by using the trade off method and...
The problem of ranking methods of interval numbers is studied in this paper. First of all we introduce two definitions for interval number together with the binary algorithm. Then we present the sorts of the existing works on comparing and ranking any two interval numbers on the real line, and point out the intrinsic relation and the invalidity in these methods. We also give some new ranking methods...
Yagerpsilas ordered weighted averaging (OWA) operator has been widely used in soft decision making to aggregate expertspsila individual opinions or preferences for achieving an overall decision. The traditional Yagerpsilas OWA operator focuses exclusively on the aggregation of crisp numbers. However, human experts usually tend to express their opinions or preferences in a very natural way via linguistic...
The conventional analytic hierarchy process (AHP) has the drawback of its invariable weights system (IWS) and the composite ranking approaches based on IWS, incapable of reflecting intrinsic characteristics of complex evaluation issues, such as nonlinearity, emergence, etc. To overcome the above drawback, with the idea of weight varying adopted, an improved ranking approach to AHP alternatives based...
Virtual organizations (VO) represent a new collaboration paradigm in which the participating entities pool resources, services, and information to achieve a common goal. VOs are often created on demand and dynamically evolve over time. One organization identifies a business opportunity and creates a VO to meet it. The collaboration's rules between the VO members are specified in a contract issued...
