Model Reusability is the important research hotspot and nodus in the domain of war simulation at all times.Operation modeling is outset,operation decomposing method based on course is used,meta-operation model is researched and discussed.Some basic concepts are put forward such as meta-operation, meta-operation model firstly,strongpoints of operation model development method based on reusable meta-operation model are analysed.Three reusability kinds of meta-operation model are discussed in the abstract secondly.Reusable meta-operation model development method based on development framework is put forward and detailed realization is gave lastly.
