Modeling Algorithm Based on String-coding Clone Selection and Reliability Forecasting
基于字符串编码克隆选择的建模算法及可靠性预测

Modeling algorithm based on string-coding clone selection is put forward.In the algorithm,evolution and choice of function structure,arithmetic relation and parameters are completed in elementary function space with string-coding clone selection,therefore,automatic production of forecasting model structures and adaptive determination of forecasting model pa- rameters are realized.Design of string-coding makes it possi- ble to randomly produce an expression in elementary function space;clone selection strategy achieves evolutionary training of string-coding antibodies.Moreover,by design of clone operator to string-coding antibodies,different antibodies evolve coordi- nately,diversity of antibodies restrains"precocity"in evolution. Reliability forecasting model of the weapon system is built uisng the algorithm.Results of experiments show that the forecasting model is of high accuracy,and lays a foundation of reliability forecasting,fault forecasting and maintenance for the control system.
