简介：当代的系统成熟评价途径没能提供导致增加的程序费用和发展风险的柔韧的量的系统评估。标准评价度量标准例如技术愿意层次(TRL)，足够地不评估逐渐地复杂的系统。系统愿意水平(SRL)是为一个特别系统的部件和连接是TRL和集成愿意水平(中断请求线)值的一个数学函数的一个最新发达的系统开发度量标准。因为对可以导致不精密的系统愿意评价的SRL数学操作的担心，SRL接受被妨碍了。这些不精密的系统愿意评价被称为愿意颠倒。用发生矩阵的一个新SRL计算方法被建议减轻这些数学担心。SRL愿意颠倒的存在越过几种系统配置为四个SRL计算方法被建模。逻辑回归分析证明建议发生矩阵SRL(IMSRL)方法比在文学建议的另外的途径有愿意颠倒的减少的存在。可行SRL方法将由设计专业人员的系统促进更大的SRL采纳并且将支持系统发展风险减小目标。
