在测试领域,被测对象的测试需求一直是一个比较模糊的概念,本文参考TYX公司对测试需求的定义,针对某型装备的测试需求,开展了基因表达式编程算法的研究.根据制导电子箱的电路特点,设计了基于IEEE 1641标准的运算符集合和变量集合、基于R-square的适应度函数、基于精英主义和轮盘赌算法的选择策略.采用部分映射、启发式变异算子和面向测试应用的插串算子和重组算子.提出了一种基于基因表达式编程算法的装备测试需求建立方法,并进行了系统实现.实验结果表明,该方法可以根据装备的观测数据生成制导电子箱的测试模型,得到装备准确的测试信号需求和具有参考意义的测试方法,此方法具有一定的通用性.%In the test field, the notion of test requirement is always not clear. The research on gene expression programming algorithm was developed for aiming at the test requirement of certain equipment consulted the definition of the TYX Corporation. According to the electrical characteristics of the control and guide box, we designed the operation set and variable set based on the IEEE 1641 standard, the R - square - based fitness function, and the selection strategy combined with elitism and roulette. The establishment method of equipment test requirement based on gene expression programming was constituted with the partially mapped crossover operator, the heuristic mutation operator, the sequence insertion operator and the recombination operator facing at test application. As shown by experiments, this method is capable of generating test model by the observed data of the unit under test, obtaining accurate test signal requirement and referenced test method with universal validity.
