This paper decomposes the time of action based on attribute model of action.

Study on constitutive relations of active region model for heterogeneous water flow in porous media;

We get the structure information of the executable models from the activity models and the binding information from the rule models and the domain information from the data models.

According to the broad use of activity models in C~3I system,the difficulty of generating the simulation models,and the similarly of the two kinds of models,we try to describe an approach to generating the simulation models indirectly,i.

A three-dimension activity model is proposed which is composed of three aspects: resource, process and technology.

In order to accurately describe the reservoir and its through-going characteristics,this paper establishes the structural model,the sedimentary microfacies model and the microfacies-controlled property model step by step using facies-controlled modeling technology with multiple stochastic modeling methods and on the basis of study results o.

This article put forward an attribute model for 5\|unit group soft structure,discussed the related method and languages,and described this model by example of BNF.

To obtain more accurate structural buried depth in seismic exploration, methods are proposed ior establishing an attribute model velocity field, the formation unit that has great influence on its velocity is considered comprehensively in the methods geologic, petrophysic and compaction data are used to build a velocity model more accurately and objectively in combination with seismic data.
