In order to provide better position combating, training and survival guarantee for the troops, the evaluation of the support capability of the positional facilities and equipment is studied. In this study, four aspects have been reviewed to gain a further insight for the composition and functions for positional facilities and equipments, namely the ventilation air-conditioning system, water supply and drainage system, power supply and distribution system and the integrated information management system. Moreover, a new AHP- fuzzy approach is introduced for the supportability assessment for positional facilities and equipment, and the evaluation results are further explored. The result showed that: The research can provide theoretical guidance and practical reference for the construction demonstration, decision, reasonable matching and maintenance and upgrade of the equipment during the installation.
