Considering maintenance resources assignments of the large-scale complex equipment, the policy that single repairman has multiple vacations is utilized to analyze a warm standby repairable system. The former models that the known conditions are usually assumed to follow exponential distribution or other typical distributions have many constraint conditions. It is assumed that the online component...
This paper presents an equivalent model to analyze switch-on process of dynamic wireless charging system of electric vehicle (EV). In the model, system initial state before switching is considered and the full response is used to describe the switch-on process. First, the system states before and after switching are discussed, and an approximate method is proposed to calculate the initial value of...
The development of complex system, such as complex ship or warship, usually contains concurrent, iterative and coupling processes. Based on multi-resolution modeling, this paper presents a new approach for analysis and organization in Integrated Logistic Support (ILS). At high system level, a macro low resolution model is presented by System Dynamics, indicating whole relationship between life cycle...
According to the real practice of hospital outpatient operating rooms, the problem of process and capacity planning is analyzed by considering the rule of balancing and increasing the resource utilization; based on queuing theory, this paper brings out the outpatient operating room process upswing plan and establishes simulation models; then, this paper puts forward the total cost objective function...
This paper examines multi-platform phased missions, which involves a number of platforms working together to achieve a common objective. A simulation model for multi-platform phased mission system reliability analysis is proposed. The model simulates the fault processes of various platforms within mission life by using a modularized multi-platform phased mission system model. With the Monte Carlo...
Understanding the effects of propagation of radio wave through ionospheric irregularities is critical in the design of transionospheric link. In this paper, some results of scintillation simulations based on the multiple phase-screen (MPS) technique is presented. The results include the fluctuation of amplitude and phase of received signal, the calculation of S4 and sigmaphi index, and the distortion...
As a typical complex embedded computer control system, computer numerical control(CNC) system development is confronted with a great challenge because of its specific requirements as well as some recent development trends such as ever more complex products while at lower prices and shorter develop cycle. In this paper, a model driven methodology for CNC system design and development is presented,...
The abuse of traditional collectivity mission reliability modeling of warship is analyzed, put forward the concept of warship unit mission is put forward, the partition principal and classification of warship unit mission is expatiated. Basing on the unit mission, traditional warship mission section is improved and new warship collectivity mission reliability model is proposed. Then the application...
