| 摘 要： | 并非结构的任何微小损伤都会加以维修，即结构损伤修复的实时性要求要弱于诊断的实时性。对智能材料与结构在实时获得结构诊断信息条件下的自修复策略问题进行了研究，应用马尔可夫过程描述智能材料结构的劣化过程，以单位时间费用最低为目标的自修复策略，给出了计算修复阀值的具体算法并用具体的实例说明了计算过程。

| Abstract: | For an engineering project,not any minor damage of any structures must be repaired immediately at any case, namely the real time demand of structure damage repair is weaker than that of damage diagnoses. It studies the policy for self-repair of smart materials and structures in term of the real time obtaining of diagnosis information. The deteriorating process of smart materials and structures was described with Markov process to achieve the self-repair policy of minimizing the average cost. Also the arithmetic to obtain the control limit policy is given and an example is presented to demonstrate the iterative process. |
