Abstract: A three-dimensional assignment model is established for the assignment of soldiers, equipment and tasks during a combat engineering support operation, in which takes the skill level of soldiers, the technical state of equipment and the cooperative efficiency into account. The constraint conditions of the model are based on the war readiness requirement of multiple skills of soldier and multiple functions of equipment as well as the operational principle of “equipment operating while soldiers taking break”. In view of the objective function and constraint conditions of assignment model, a virtual equipment method is adopted to disintegrate a multi-functional equipment into smaller combinations of single-functional articles. A quick solution algorithm is also designed on the basis of the idea. A detailed introduction is given to the application of the assignment model with illustrative practical instances. The practicabilities of the assignment model and the quick solution algorithm are verified. Key
