The multi-state weighted k-out-of-n system model can illustrate the performance and reliability/availability relationship between components and system so that attracted more and more attentions in recent years. Under the condition that the state probabilities of components are dynamically changing with time, this paper presents a generalized instantaneous availability model for multi-state weighted...
Flight Control System (FCS) is a key component in aircraft. The high reliability of FCS is needed to ensure the safety flight. In order to achieve the high reliability and make the overall mass and volume as small as possible, mission reliability of the multi-redundancy voting structure of FCS is used as the objective function. The types of the elements and the number of redundancies are chosen as...
This paper presents an efficient way to maximize the throughput of mixed batch/continuous process based on integrated hybrid time Petri nets and genetic algorithm. The scheduling problem of process is mapped as the solution of the optimal regional state sequence in HTPNs. The transition firing decision model is developed according to the enabling and firing rules, and a genetic algorithm of scheduling...
An improved artificial bee colony algorithm (IABC) is proposed in this paper, which is aimed at some defects of ABC such as low optimization precision and easy to fall into local optimal value. A new method is introduced to produce a new solution when the bees are going on neighborhood search in the improved algorithm. IABC is as simple as ABC to implement, but can greatly improve the ability of seeking...
