测试序列优化设计是故障诊断中的重要组成部分，最优测试序列能提高故障诊断的效率，常见的故障诊断系统均基于二值属性，而多值属性系统的测试优化问题研究的较少。针对多值属性系统测试序列优化问题的特点，提出了一种改进蚁群算法，结合二值属性系统和多值属性系统的关系，设计了适应于多值属性优化的状态转移规则和信息素更新机制。针对在等测试费用和故障先验概率的情况下不能寻优的问题，制定了对应的优化标准，符合实际的测试需求。通过对比试验，证明了其能解决电子系统多值属性系统的序列优化问题，扩展了多值属性电子系统的测试优化策略。

Test sequencing optimization design is an important part of fault diagnosis. The optimized test sequence can improve the ability of fault diagnosis. The binary attribute systems were researched widely,while there are fewer researches on multi-value attribute systems. According to the multi-value attribute system test sequencing problems,a novel Ant Colony Algorithm was advanced. Combining the relation between binary attribute systems and multi-value attribute systems,multi-value attribute optimization state transition rule and pheromone update mechanism were designed. Under the same fault prior probability and test cost,a novel optimization standard was advanced,it satisfies test requirements. The contrast experiments prove that the proposed scheme can solve multi-value attribute electronic systems fault diagnosis and the strategy has been extended.
