Existing clustering algorithms need to specify the number of clusters and to select initial points using human input, which lead to inferior clustering and optimisation outputs. Here, an improved grey decision-making model based on the thought of affinity propagation algorithm and grey correlation analysis is proposed to solve these problems. According to the panel data class and the inter-class candidate...
The aggregation of uncertain linguistic variables in uncertain linguistic multiple attribute evaluation is researched in this paper. To overcome the error of the model used in the literature to compare and sequence every two uncertain linguistic variables, a new model that can accurately calculate the possibility degree is presented, which guarantees that the subscript value of an uncertain linguistic...
Concurrency control is one of the key factors in computer supported cooperative work. Through researching conflict of concurrency control mechanism and CSCW, this paper introduces the rough set into the conflict-detection, and forms a new algorithm idea. Also, the paper analysis the feasibility of the new algorithm and gives an example.
