Hasse diagram is a very popular method for multi-criteria evaluation and decision making, but now we just use no-weighted Hasse diagram for each attribute. This paper concerns how to get the weighted Hasse diagram. Firstly, assessment cumulated matrix based on the weights of each attribute is proposed, then the weighted Hasse diagram can be drawn, and Bubley Dyer algorithm, which is a Monte Carlo...
Research on effectiveness evaluation method of aviation material support has important practical significance for the operational capability of aviation weapon equipment established and maintained. This paper aim at uncertain factors and dynamic characteristics of evaluation process, put forward the synthesis evaluation method of aviation material support based on Set Pair Analysis (SPA) and Markov...
In this paper, a hybrid fuzzy DEMATEL-TOPSIS model for multi criteria decision making is presented. The criteria weights are determined based on separate cause-effect assessment of a group of professionals using a modified fuzzy DEMATEL approach. The resulting criteria weights are applied to the decision analysis where an improved fuzzy TOPSIS model is presented to aid in the decision making process...
Generalized stochastic Petri net model is proposed for support system with a classic structure of three-echelon repair and two-echelon inventory. Based on Petri net workflow models of various maintain processes, extendable queue models with generalized queuing time concept are presented to analyze performance equivalent time. A strategy of spare parts inventory minimizes the number of backorder for...
We focus on an opportunistic communication system consisting of multiple independent channels with time-varying states. With limited sensing, a user can only sense and access a subset of channels and accrue rewards determined by the state of the sensed channels. We formulate the problem of optimal sequential channel probing as a restless multi-armed bandit process, for which a powerful index policy-Whittle's...
