In view of the problem that the current engineering support force grouping mainly depends on the experience and subjective decision-making of the commander, a method of engineering support force grouping based on fuzzy clustering is proposed. The correlation characteristics between engineering support force and mission requirements are analyzed, and the method of engineering support force grouping is verified by constructing an urgent military road mission example. The results show that the method can divide the engineering support forces according to the task requirements, and provide support for the rapid formulation of engineering support action plan.
