The goal of this work is to extend a model of timed object-oriented Petri nets(TOPN) to allow modeling and analyzing dynamic systems with timing effect on system *** the proposed Fuzzy timed object-oriented Petri net(FTOPN),we attach temporal fuzzy sets to each transition objects accounting for the aging of *** particular,we investigate a new way to represent and deal with timing effect in dynamic *** also supports learning similar to that in fuzzy timed Petri net(FTPN).Finally,we use FTOPN to model a real decision making model of our cooperative multiple robot system(CMRS) to demonstrate its following benefits:independent training for its supporting object abstraction and size reconfiguration for its object granularity control function.

The Bohai Bay West Coast is a typical muddy coastal zone which is also the most sensitive and vulnerable areas in the geological,ecological *** recent years,human's activities are greatly affected its change's speed and *** using a combination of Remote Sensing and GIS technology,this paper utilizes lots of Remote Sensing data to monitor the coastline position,changes rules and influencing factors over the past 20 *** coastline extraction method can be used such as supervised classification,threshold extraction,object-oriented and other methods and in this paper we use the threshold extraction of water index and object-oriented approach. With the spectral index and water index,the line between the sea water and light beach is extracted whose changes can monitor the sediment deposition in real time and *** Remote Sensing methods can avoid long period difficulties and shortcomings of site visit to survey the coastal reclamation case. The results show that:(1) The coastal shoreline overall present the variation of advancing seaward.(2) The dominant factor of port construction,violation of human activities such as sea-land reclamation dominated the shoreline *** construction of Tianjin Lingang Industrial Area in Binhai New Area has led the coastline to the sea advanced nearly 10 km since 2005;(3) The environmental impact of shoreline changes mainly reflected in the river longer and narrower,resulting in sediment deposition to make rivers more shallower and more poor in flood discharge capacity.

This study attempted to applied object-oriented method and its special ways such as decomposition, abstract, modular, package to solve hazard identification problems and carry out quantitative analysis of civil airport safety risk. Application of object-oriented inheritance, coverage, polymorphism and other features makes the process of hazard identification more simplified. This program can help us to find the object properties, the method and their interaction of BaseClass and its sub-class. According to the BaseClass of hazard class of derive from a civilian airport, providing supporting data for subsequent risks analysis of quantitative studies.

During the Large Commercial Aircraft development process through the form of “Manufacturer-Supplier” model, the aircraft design work is allocated to multiple systems and sub-systems down to single equipment and component. This leads to the challenges in the joint design of aircraft PHM system. It is particularly difficult to coordinate between the data and model. Considering the real needs in the optimization of the aircraft PHM system design, this paper describes the establishment of the parameter coupling model between the PHM system and the contributing system (including the sub-system, equipment and components) through the concept of integration. Meanwhile on the basis of the model, the parameter mapping (including parameter identification, demonstration and transfer) among the PHM system and each contributing system, sub-system, equipment and components can be realized through the object-oriented method, so that the effective control of the data collection, transfer, calculation and storage can be achieved. The significant benefit in ensuring sufficient coordination, increasing system design efficiency and quality during the aircraft PHM system joint design is verified in this paper through the investigation of real-world application.

Based on high resolution remote sensing imagery and in combination with multi-temporal imagery, this article classified land cover of Miyun reservoir area using the object-oriented classification method. The results showed that the deciduous broad-leaved shrub, deciduous broad-leaved forest, dry land, and grass accountedfor 92% of the total area. The study proved that multi-temporal satellite images are critical in grouping those objects with different spectrum together, like the cultivated land. Moreover, plenty of ancillary data is good to distinguish the different objects with same spectrum.

Firstly, an improved descriptive method based on OWE (object With Event) for software component has been analyzed and discussed. Then, the strategy for the implementation of software reuse is probed into. At last, the support of Inheritance mechanism for software reuse and an improved strategy in distributed processing environment have been stressed on.
