A Matlab/GUI Based Automatic Assessment Research of Aircraft Power Supply System Architecture

Evaluating architecture of aircraft power supply system precisely is the basis of optimizing aircraft architecture design. The multi-index evaluation of its architecture involves reliability, expense, maintainability, weight and power quality, which provides designers with the optimal decision information, including two steps: normalize individual evaluation index and export each single-index result; consider weight coefficients and export a comprehensive multi-index result. A software based on Matlab/GUI is designed, which is used to output evaluation results of different system architectures according to users' input. Especially, the power supply system is abstracted into a network graph and a matrix is used to record information in order to make computer easier to recognize and deal with. In addition, an algorithm named Depth First Search (DFS) is used to search all the minimal path sets from the source node to the essential node in order to realize reliability evaluation efficiently.
