Analysis, design and implementation of an object-oriented framework in Ada95

This paper describes the analysis, design and implementation of an object-oriented framework for discrete event simulation in the programming language Ada95. The framework was constructed in an industrial setting so that conclusions are drawn from first-hand, practical experience with this approach. After defining the term 'Object-Oriented Framework', discrete event simulation is analyzed as the domain of concern in the given context, producing a class diagram for that domain in the Unified Modelling Language (UML). Following the analysis activities, the framework is designed and described, again using diagrams of the UML. In further sections the mapping from design artifacts to code in Ada95 and the usage of the framework are shown. The article finishes with a summary of the experience gained and the lessons learned.
