Design And Realization Of OAS For Enterprise Based On Work Stream Technology And GIS

Today, with modern information technologies growing rapidly and enterprises' projects distributing widely, OAS is playing a more important role in enterprise management. However, traditional OAS always focusing on cutting some work into pieces of tasks, this model can hardly be adaptive to the changes of departments and services. Meanwhile, it neglects the demands of spatial information in enterprises, In summary, it is necessary for enterprises to construct an OAS integrated flexible work stream controls with GIS advantages in spatial analysis in order to plan enterprise resources more practically and more efficiently.Having studied the changeable work stream structure principles, the thesis designs and realizes an OAS based on work stream and GIS technology. After referring to the traditional OAS, the thesis firstly introduces a new form management model controlling changeable work stream structure, and then it integrates GIS with OAS to realize an integrated management of daily functions and spatial information. Details of the thesis are as following:First, it studies the ways of realizing changeable work stream controlling. Having analyzed how to control changeable steps of work stream, the thesis introduces a storage model about changeable structure work stream. This storage model offers a feasible solution for meeting OAS's daily needs when confronted of changeable work stream.Second, that is where the thesis discusses the key problem of integrating GIS into OAS, which refers to the integration of spatial information management and OAS. The problem includes: integration methods, visibility technology, data processing and management, spatial analysis technology and aided decision technology.Third, on the basis of the principle above and considering the system target, the thesis mentions the realizing method of the system using ComGIS technology and C/S frame structure. Then, it expatiates on the system's main function including: role management, changeable structure stream management, analysis and aided decision.Fourth, the thesis summarizes the priority of the system in the end. Besides, it points out such aspects to be improved as network structure, multi-source data management, integrate methods between GIS and OAS, which reflects the system's scalability.
