In industry or nature, ‎there are systems subjected to a secuence of shocks ocurring randomly in time‎. ‎these shocks are causing aging or failure of system‎. ‎According to the type of shocks‎, ‎shock models divided in two major groups‎, ‎Extreme Shock Models and Cumulative Shock Models‎. ‎In the extreme shock models just impact of last shock named fatal shock would be studied and in the cumulative shock models accumulated effects of accured shocks‎ would be studied.

‎In reality it is possible ‎that‎ ‎effects of shocks on the system are not coincide with no kind of named models so Introducing the other types of shock models and survey of aging systems is necessary‎. ‎In this article we aimed to introduce some of the new shock models, also in each model survival probability and the corresponding failure rate function ‎were ‎derived.‎
