The invention provides a weapon system accompanying spare part demand prediction and evaluation method and system based on task and fault interval time (MTBF). The method comprises the following steps: arranging MTBFs of field replaceable units (LRU) of a weapon system; calculating the damage number of the LRU under a certain guarantee probability to predict the number of spare parts required for reaching the certain guarantee probability; in combination with the unselected spare parts influencing the combat, considering whether the spare parts are dual-redundancy design or not, and selecting the LRU which influences the combat and is not dual-redundancy as the spare parts; and evaluating the spare part configuration of the final weapon system. The spare part demand is predicted, the configuration of the spare parts is reduced as much as possible on the premise of ensuring the weapon system combat, and the scientificity and the evaluability of the spare part configuration are enhanced by adopting a reasonable
