In order to achieve the interoperability among different devices made from different manufacturers, IEC61850 protocol is applied to the energy management system of microgrids (MEMS) in this paper to make the standardization of data communication among the microgrid. The communication system model of three layers for the microgrid is proposed and applied into microgrids. And the IEC61850-based data...
This paper focuses on the multiple attribute decision making problems with the attribute values being preference orderings and interval numbers evaluations. For the attributes with preference orderings evaluations, the fuzzy preference relation between the alternatives are calculated and the their rankings values are further normalized by measuring their relative distances to the ideal point; For...
This paper focuses on the multiple attribute decision making problems with the attribute values being linguistic variables. The decision matrix is normalized by calculating the superiority possibility of the linguistic attribute values to their corresponding positive ideal ones. Furthermore, a mathematical programming model is set up to figure out the attribute weights with the overall values of the...
This paper proposes a grey relation-based approach to customer value assessment while customerspsila information is expressed in the form of interval numbers. By calculating the grey relation coefficient between interval attribute values and the ideal one, the decision matrix in the form of interval is transformed into a definite one, based on which the attribute weights are determined in order to...
The dual uncertainty information, i.e. fuzzy information and grey information in the problem of multi-attribute group decision making, are studied in this paper. Based on the theories of fuzzy mathematics and grey system, the concept of fuzzy grey number and its algorithm are defined firstly, then a model of dual uncertainty multi-attribute group decision making is proposed. Thirdly, the fuzzy grey...
