  • 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.

  • This paper presents requirements for workflow management systems supporting CITIS. We propose an architecture of global workflow management system which aims at supporting external workflow among different organizations rather than internal one. The architecture consists of five key elements, that is process definition language, process graphic design tool, control engine, status monitoring tool, and interface models. For each of these elements, implementation requirements are presented and its major functions are described. A key concept to the CITIS standard is the integration of disparate systems in distributed environment. This leads us to place a special emphasis on the interface models that can enhance the interoperability between externally participating workflow systems. Two interface models for the global workflow management system are explained. CORBA, the most widely accepted standard for distributed object management, can be adopted to facilitate the integration. World Wide Web can be used for the underlying platform on which information is exchanged and the status of processes instances is monitored. The workflow management system can provide a ready and easy access to and management of the data for CALS environments.

  • In this paper, we introduce the design and development of a web-based workflow management system. The goal of the developed system is to manage business processes occurring in the CITIS (Contractor Integrated Technical Information Services) environment. The system is composed of three main modules: Process Designer, Workflow Engine, and Client modules. The Process Designer is a module that provides the environment for the build-time function, which generates the specifications of processes. The module presents the capability of defining nested process models, which is powerful in particular for designing complex processes. Since the other two modules are implemented using pure Java technology, the Workflow Engine can be implemented on any platform and the Client programs can be accessed via the WWW interface. This indicates that there is no need to install any client programs at the client-sides. Users who has a connection to the internet with web browsers, such as Internet Explorer and Netscape Navigator, and has a proper right of access can utilize the normal client, monitoring client, and system administration client programs. Communications between the workflow engine and the clients are implemented using the java servlet mechanism. The workflow system can serve as the underlying platform of process management tool in CALS and CITIS environments. An example scenario of using the system is presented.

  • This study aims to develop an approach to construct IWSDB for National Defense CALS. Along with the introduction of Korean version of CALS conception, it is essential to analyze the national defense system with a new information technology for the construction of IWSDB. A long-tenn goal of CALS is to construct fully Integrated Data Environment (IDE) and establish IWSDB for the application of CALS conception to the life cycle management of weapon system. IWSDB is a set of databases that contain digital data. It supports common interface of data objects and databases throughout the life cycle management of weapon system, including design, engineering, analysis, manufacturing, operation, and logistics. etc. The goal of this study is threefold. First, we propose a right direction for the establishment of Integrated Data Environment. For the integrated database technology, we use the five schema architecture and the distributed object oriented technology that will lead to the "share of data." Second, we present the most effective IWSDB architecture for defense CALS, which will provide the efficient data sharing by business process modeling. Third, we suggest that IWSDB should be constructed based on the process which is related to the acquisition and logistics of weapon system for the national defense, and at the same time it should be implemented with GITIS for government agencies and CITIS for the industries in order to obtain the efficient data sharing.
