Efficient S/W framework for S/W reuse of steel manufacturing process system

Operation skills and know-how of the operators in the steel making industries are kept in the application software of process computer system in the factory. Although they are developed by using component based development, or CBD, the developed components are very dependent on each other and application engineer feels it very difficult. To solve this problem, we propose an efficient S/W framework for S/W reuse. The proposed S/W framework is composed of feature model, layered architecture, workflow model, and independent components. We expose all the kinds of variation points and manage them by using developed S/W engineering tool. After we automatically generate application S/W codes from S/W assets developed by using the proposed S/W framework, we apply them to continuous casting pilot plant and find them performs very well. After finding the feasibility, we extendedly apply the efficient S/W framework to several systems in the steelworks. To find the performance of the generated codes, we calculate maintainability index and reusability rate, and make sure that the proposed framework is very good for maintainability and reusability of the application S/W.
