After analyzing the merit and lack of 9I model, the main idea is proposed: to distill some basic topological relations from 9I model, of which the composite topological relations of complex objects are made up. In detail, the composite topological relationships between region and region, line and line, line and region are particularly discussed;(2)Analyze the characteristics and inner relations of cadastral features. According to the expressional model of complex topological relations, the author discovers the possible topological relations between parcels, parcel lines and parcel points. In addition, sum up the general topological relationship rules of cadastral data.(3) Then the topological relations model is extended to the spatio-temporal data. Time in cadastral database and change semantic are discussed. It's redefined that spatio-temporal topological relations is composed of time, location, status and event relation. Spatio-temporal topological relationships can be represented by extended 4I model. Taking cadastral parcels as example, there are different possible spatio-temporal topological relationships between parcels when they are extended, shrunken, split, merged or others. Thus, some deductions are drawn that, for example, if parcels have be coexisting for some time they are impossible to be overlapped. Furthermore, the parents of parcels alternated and their possible change types can be detected by their spatio-temporal topological relationships.(4) Before carrying out the experiment, the calculation method must be designed.

Considering the gap between academic research and real world application, the characteristic of manufactories of "much variety and little batch", this paper discusses the abstraction and modeling of the workshop performance using colored Petri net characterizing definite description of DEDS. And rule bases are applied into the model to tackle the dynamic events and disturbances with dynamic scheduling. After analysis on agile response of MES and integration of its scheduling model, by adopting distributed component technology the workshop scheduling model was capsulated as a scheduler to realize the scheduling module of MES easier to be integrated and rapidly reused. Finally a prototype of scheduler is proposed.
