一個被廣泛用於驗證實時系統的方法是根據被驗證的實時性質，使用適當的雙向模擬等價關系使無限的狀態空間轉化為有限的狀態等價類空間.演算法只需要在這個有限的等價類空間里搜索就可以得到正確答案.但是，這個等價類空間的規模一般隨著系統規模的增大而產生爆炸性的增長，以至於在很多情況下，窮盡搜索這個空間是不現實的.該文引入了一個等價關系來驗證一個由多個實時自動機通過共享變量組成的並發系統是否滿足一個線性時段特性.同時，還引入了格局之間的兼容關系來避免對狀態等價類空間的窮盡搜索.基於這兩個關系，文章提出了一個演算法來驗證是否一個實時自動機網滿足一個線性時段特性.實例研究顯示，此演算法在某些情況下比其他一些工具有更好的時間和空間效率By debo the opthal object function, along with wt the man oorm ofoint velocities, the posinon conii ' ol modl w on two bp nend netwoiks for redundan thngt twpulators is establisan. the hmpd contidl m for position and foi ' ce is put fotw. bed on bp neural tw, the inare lerc soution and the join driven toiques are obtained
