Description

technical field [0001] The invention provides an optimization method for the trade-off between efficiency and cost of a remote sensing satellite, which can analyze and trade off a design scheme of a remote sensing satellite to obtain an optimal design scheme with high efficiency and low cost. Background technique [0002] One of the most important tasks in the early stage of remote sensing satellite development is to optimize various design options, that is, to balance the two requirements of efficiency and cost. Efficiency is the degree to which a remote sensing satellite satisfies a set of specific mission requirements under specified conditions and within a specified period of time, and is a comprehensive measure of satellite performance and reliability. The cost is mainly the development cost of the remote sensing satellite, which is closely related to the design parameters of the satellite. Optimizing the trade-off between efficiency and cost is a necessary means to ac...

Problems solved by technology

Domestic research work on efficiency-cost trade-off optimization started relatively late. Although some achievements have been made, there is still a certain gap. Therefore, it is necessary to study the problem of remote sensing satellite efficiency-cost trade-off optimization.

[0004] Compared with weapon systems, the difficulty of cost optimization for remote sensing satellites lies in the fact that satellite systems are non-repairable, and there are degraded usage conditions during operation. The working mode and actual operation conditions are complex, and the existing effectiveness evaluation models cannot meet the actual engineering requirements. need

At the same time, the evaluation dimension of the satellite cost model is single, which cannot fully cover the cost-influencing factors in the satellite development process. In the design process of remote sensing satellites, it is often restricted by a series of continuity constraints and discrete constraints. The benefit-cost trade-off optimization model

In addition, in engineering design, designers often rely on the experience of designers to try and optimize the design of remote sensing satellites. Without the support of automatic means, it is not only difficult to approach the optimal solution, but also may cause waste of design resources.
