Abstract: Equipment operation mission activity frequency and support activity frequency calculation method is presented focused on equipment operation mission activities and support activities analysis launching on equipment operation mission.Equipment support resources are divided into two evident categories which character as the activities where equipment support resources are processed or consumed.Equipment support resources quantity is forecasted via to decrypting equipment support resources consumption and occupancy quantify relationship.Equipments support footprint forecast model is constructed according to support resources weight and volume parameters.So equipments support footprint can be evaluation beginning with equipment operation mission requisition input,and a practical application case was given.It is proved that the presented model and analysis mythology is effective infrastructure theory support for equipment system deployment analysis and important reference for equipment logistics support system design requirements establishment and evaluation.
