The factors include the retarded time of torpedo engine starting, torpedo velocity at tube outlet, confined elevator angle and ship rolling angle. Similarity variables were defined for the four factors and values of the variables were determined through combination of experimental data and simulation results.

在舰艇鱼雷发射初期弹道建模与仿真研究中，重点研究鱼雷发动机启动延迟时间、鱼雷出管速度、管制舵角、舰艇横摇角对初期弹道的影响，将该四项因素作为相似元，再根据实航试验数据的袋深与仿真计算结果的袋深求出相似元的值。

Firstly, system model depicted by TSIOA is transformed into an USTGSS (untimed stable label transition graph of symbolic state) which does not contain abstract time delay transitions. Then, the testing methods based on LTS are used to the generate transition sequences from USTGSS according to structural coverage criteria. Finally, a process of constructing and executing the test cases is given, in which object functions of time delay variables are imported, and time delay variables used in the transition sequences are solved dynamically by linear programming techniques.

该方法首先将时间安全输入/输出自动机描述的系统模型转换为不含抽象时间延迟迁移的稳定符号状态迁移图(untimed stable transition graph of symbolic state，简称USTGSS)；然后采用基于标号迁移系统(labeled transition system，简称LTS)的测试方法来静态生成满足各种结构覆盖标准的包含时间延迟变量迁移动作序列；最后，给出了一个根据迁移动作序列构造和执行测试用例的过程，该过程引入了时间延迟变量目标函数，并采用线性约束求解方法动态求解迁移动作序列中的时间延迟变量。
