Research Of Key Technology And System Of CITIS For CALS

CALS (Continuous Acquisition and Life-cycle Support) is one of the strategies launched by U.S. DOD and enterprises. In order to develop, manage, exchange and use the information of affair and technology between government and industrial enterprises ,an integrated data environment is established by best technology, process and standard. CITIS(Contractor Integrated Technical Information Service) is in an important position in CALS system in order to realize three main targets that paperless task environment ,sharing of information and consistency of electro data. CITIS integrates the information created by all of the users including prime contractor , sub contractor , suppliers, and others by computer technology, network technology and relative technology of CALS, and create a data sharing environment in order to share information in the complete life-cycle.The main research work and innovative contributions of this thesis are as the following:Firstly, the analysis of invention, development and relative technology about CALS and CITIS and their present situation domestically and abroad are presented. The status of CITIS in the enterprise information management is defined and the research problem of CITIS in CALS is discussed in the paper.Secondly, an enterprises information sharing model based on CITIS has been put forward by analyzing user type of CITIS , mode of data exchanging, adoptive standards and integration of system. CITIS platform that will be developed in the text is pointed out .And the function and characteristics of the model will be presented.Thirdly, the key problems of realizing the enterprises information sharing model based on CITIS is illustrated and analyzed according the CITIS concept and the situation of enterprises. The key problems including: standardized technology of CALS, integration technology of system and technology of data security.Fourthly, methods and process designed for CITIS platform are presented in the paper. CCO (Customer Concept of Operations) is put forward according to the CDRL (Contract Data Requirements List). And archetypal system of CITIS platform isdeveloped according to the CCO, which can be use for reference when the enterprises implement CITIS in the future.Finally, an archetypal system of CITIS platform is developed and introduced. In conclusion, the research results not only have the theoretical value but also practicability and maneuverability.
