In this paper, we discuss CITIS(Contractor Integrated Technical Information Service) as the information infrastructure of CALS. CITIS is a contractor-developed and maintained service to provide electronic access and/or delivery of Government-procured contractually required information. As the concept of CALS is expanded government acquisition process into industry business, the CITIS is also expanded military CITIS into commercial CITIS. First, we describe CITIS services and functions defined by MIL-STD-974, and then specify the difference of military CITIS and commercial CITIS. The problem of current CITIS for inter-operable business process is indicated, and legal issues for sharing of CITIS data are also discussed.

In this paper we present the development of CITIS(Contractor Integrated Technical Information Service) reference model system which can be utilized for electronic commerce among enterprises. For the physical analysis target model, we selected switching system businesses of Korea Telecom. From analysis of life-cycle business process and data, we derived CITIS reference model containing CITIS To-Be model and CITIS scenario. Derived CITIS reference model is generalized so that it can be used not only for switching system businesses but other business areas regarding CITIS implementation. On the base of the derived CITIS reference model, We also developed CITIS information management system and CITIS-support workflow system as CITIS reference model system. Developed CITIS reference model system supports information and business process sharing among enterprises on internet and it does make a contribution to expansion of CITIS which is moving from conceptual research towards real implementation phase.

We followed the below procedure to establish the development strategy of CITIS standard. At first, we investigated Military CITIS and Commercial CITIS to establish the concept of CITIS and examined several implemented examples. And using the previous analysis, We analyzed the structure of the functions, the technologies and the standards. To establish the development strategy of CITIS standard, we divided CITIS standards into three category, These are infrastrucure standard, data standard and process standard. In the process standard, we analyzed how we develop a formulated process and which item we select to make formulated official documents. And finally, We explained the implementation plan and extension strategy of government-enterprise and inter-enterprise CITIS respectively.

In this paper, we discuss about the implementation of CITIS(Contractor Integrated Technical Information Service) which is information infrastructure for CALS. CALS concept is introduced by DoD(Department of Defense, US) to exchange technical data of product's life cycle electronically. This CALS concept is accepted by commercial industrial area and considered as a part of global concept of Electronic Commerce. CITIS- a service defined by MIL-STD-974- is about to be implemented by commercial industrial society, too. But, until now there is a few sites implementing CITIS and especially in Korea. In this paper, we discuss characteristics of some CALS/CITIS implementation and solutions, and introduce ETRI-CITIS.

Among the standards of CALS, CITIS(Contractor Integrated Technical Information Service) is a standard in information share procedure which manages all data and services occurred between a contractor and a purchaser. CITIS services have some security problems like authentication problem and repudiation problem, when they are implemented using the Internet. To solve these problems, CITIS needs a user certificate system which can allow to access important information only to qualified users. This paper proposed a PKI(Public Key Infrastructure) Certificate Authority for CITIS, and created a real User Certificate System which can be adjusted to circumstances of real CITIS.

Korea government is making an effort to improve the efficiency in construction industry by introducing CITIS (Contractor integrated Technical Information Service). In order to provide a base for the application of CITIS into the construction industry, this research provides a concept of virtual factory which should be incorporated into CITIS system for the successful collaborative work in the virtual space. It then implements a prototype system through process and data modeling to apply into the road construction projects. The prototype system is tested to verify its efficiency. Finally, lesson learned from these works is provided to advance the current CITIS toward a collaborative virtual factory.

CALS, being widely adopted by industry, is a strategy to share integrated digital product data through a set of standards to achieve effieciencies and competition in business. For CALS implemetation, creating a shared information system is necessary and CITIS is proposed for that. CITIS shall provide on-line access and automated exchange of all the technical information between contractor and service provider, and the function of CITIS is difined in MIL-STD-974. In this paper, regarding CITIS as a infrastructure of information for CALS, we proposed CITIS server system which comprise global data sharing software, global data management system, workflow manager, and configuration management maneger.

CITIS(Contractor Integrated Technical Information Service) is a service standard which specifies guidelines which are required for the fulfillment of a contract between a purchaser and a supplier. It was initiated as a military standard and is now becoming a commercial standard. In this paper, we propose how the guidelines, which were usually developed by Client/Server methods in previous works, can be implemented in WWW environments, and show a prototype which can be used for the confirmation of CAD drawings between contractors(purchaser and provider). We have a hope our study can provide a small foundation for the building of CITIS references.

CALS의 개념이 정부 및 국방조달 프로세스에서 기업간의 정보공유로 확대됨에 따라, CITIS도 Military CITIS에서 Commercial CITIS로 확대 발전되고 있다. CITIS는 CALS를 구현하는 과정에서 제품 및 시스템을 발주하는 조달자의 요구에 따라 제품 및 시스템을 납품하는 공급자 사이에서 계약에 따라 발생하는 기술정보 및 비지니스정보를 전자적으로 공유 및 교환하는 것으로 CALS 구축에 있어서 중요한 개념이라고 할 수 있다. 본 논문에서는 Military CITIS를 Commercial CITIS로 확대 적용하기 위하여 DODI 5000.2를 기준으로 CITIS 관련 각종 표준에 대한 분석을 하였다. 이를 통하여 국내 전자 환경에 적합한 Commercial CITIS의 개념을 정립하였다. 또한, 전자산업에서 조달자와 공급자간의 정보흐름과 Business Process 분석을 통하여 Commercial CITIS 서버 Class를 도출하였으며 이를 통하여 CITIS 서버의 아키텍쳐 모델을 제시하였다.

As the lifecycle of a product becomes shorter, the communication between a contractor and a supplier in product information has got more importance. The CITIS(Contractor Integrated Technical Information Service) is required to provide authorized users with access to both data and applications they need to complete a task for contract. With the growth of WWW, there has been much study for the use of WWW for the implementation of CALS. The WWW has been proved as an efficient tool for CALS implementation due to its of publicity, openness, and free accessibility. In this study, we suggest using WWW tools, here, an intranet tool, as a basis for the implementation of CITIS
