Aiming at the problem of effective matching between engineering operation equipment capability characteristics and task requirements in engineering support task assignment of engineering corps, an engineering equipment/task capability attribute set is established, and a task assignment method based on multi-capability attribute matching is proposed. According to the characteristics of engineering support tasks, the capability attribute requirements are decomposed, the operation capability of engineering equipment is analyzed, the priority assignment algorithm of engineering equipment capability is given, and the engineering equipment set with the shortest operation time is optimized. Taking the construction of urgent military road as an example, the verification results show that the method can improve the matching degree between engineering equipment and task capability attributes, which provide support for commanders to accurately and efficiently formulate engineering support plans.
