In view of the problems existing in the analysis of battlefield environment factors affecting engineering support tasks in the current engineering support command, the battlefield environment impact analysis model is constructed. The information of battlefield environment factors and its association with engineering support tasks are described normatively, the weight of multi-level evaluation index is determined by using AHP, and the comprehensive influence coefficient is calculated by improving fuzzy comprehensive evaluation method. The results show that the model can provide data support for accurate decision-making of engineering support command.
