The Problem of operation tasks and platform resources matching(MPoTP) is the main topic in the preparation phase of battle. In order to consider the loss of the platform capacity in the process of combat, the loss coefficient is introduced in the process of problem modeling, and the problem model can be more conformable with actual combat. An approach to the problem model based on the multi-PRI list...
IMA avionics system integrates much more aviation buses as networks in avionics system. The modeling and simulation are the flexible and effective method to design and evaluate IMA avionics system which uses FC as the main network. By using simulation tool OPNET, a switch module is proposed and a FC-1553B network is simulated. We study the impact of 1553B on performance of FC network. Simulation results...
The problem of constructing optimal test strategy to diagnose permanent faults in electronic and electromechanical systems is considered. The test strategy problem is formulated as an optimal binary decision construction problem, whose solution is known to be NP-complete. Our approach integrates information gain of test into heuristic search methods to subdue the computational explosion of the optimal...
The paper introduces the conception of significance and presents a new algorithm -a fuzzy weight algorithm with multiple supports for mining association rules, which is based on fuzzy-comprehensive evaluation and the algorithm of multiple minimum supports. The new algorithm takes support and significance into consideration at the same time when large itemsets are produced, making the filter criterion...
Component Based Software Engineering (CBSE) is an excellent candidate to achieve greater software understanding, reuse and reliability. In this paper, we presented how this paradigm could be applied in the development of system from an alternative way. In this way, that is, to imitate the way of circuit board assembly process, we brought forward the concept of soft-board and further, the soft-board...
According to the characters of dynamic and SOM clustering algorithm, propose a novel clustering method, rough dynamic clustering based on grid-density algorithm (GDRDC). The algorithm contains initial clustering stages and precise adjustment stages. During switch from the first stage to second stage, according to rough sets idea, class kernel and freedom point sets base on grid-density are determined,...
