This paper investigates a multiple attribute decision making problem, whose attribute values are stochastic rough normal distribution. We define stochastic rough normal distribution variables, and then propose rules and stochastic rough normal distribution aggregation operator (SRN-WAA). The method based on SRN-WAA operator is proposed for the problem of the incomplete information on attribute's weights...
With respect to the problem of improving the consistency of linguistic judgment matrix, a new method for improving the consistency of linguistic judgment matrix is proposed in this paper. Firstly, the linguistic judgment matrix is transformed into reciprocal matrix. Secondly, a method for improving the consistency of reciprocal matrix is constructed according to the exiting results. Secondly, the...
With respect to the aggregation problem of group decision-making based on ordinal preference information set, a processing method is proposed. The preference information is transformed into the educed matrix (fuzzy reciprocal judgment matrix) through quantifying ordinal preference information, it comes to conclusion that educed matrix is fuzzy reciprocal judgment matrix and the educed matrix meets...
Regarding assessment level of experts in group decision making based on different granularity linguistic judgment matrices, the linguistic judgment matrices are quantified through constructing transfer function in this paper, the matrices are transformed into the reciprocal matrices with 1-9 scale, furthermore a method to assessment level of experts is proposed based on the theory of mathematical...
A multiobjective optimal service restoration methodology for shipboard power system (SPS) using a simulated annealing genetic algorithm is presented. All the multiple objective functions related to restoration problem for SPS are formulated as fuzzy sets. An analytic hierarchy process (AHP) is adopted to determine the weighted factors of each objective functions which is more convenient to be apprehended...
The ability to efficiently and effectively select the inter-organizational and heterogeneous services is the important support for the development of the Web service technology. Quality of service (QoS) profiles of Web services are crucial in determining which service best addresses the user desires and objectives. This paper developed a general QoS-based service selection method. By importing the...
This paper gives a new analytical solution for assessment level of experts in multi-attribute group decision-making. A new consistent estimator is made by the method on basis of mathematical statistic theory, according to experts' information provided in decision-making matrices, assessment level of experts is estimated and judged adversely, that is difference of assessment level and estimation of...
The weight estimation approach for uncertainty judgment matrix-interval grey numbers complementary judgment matrix in analytical hierarchy process (AHP) is studied. First, the random certainty judgment matrix of the interval numbers complementary judgment matrix is defined based on the random simulation idea. Then, the weight of the interval numbers complementary judgment matrix is expressed via the...
As an important approach of enterprise improvement, business process re-engineering (BPR) has become the basis of enterprise information, organization change, etc. Great changes are difficult to be obtained only by experts' subjective decision-making, and efficient decision-making support tools are lack at the moment. Business process mining (BPM) does well in knowledge management and decision-making...
