An automated change impact analysis and management approach is vital to handle the complexity of adapting software during its evolution. Such an approach reduces the maintenance cost and provides for adequate decision making when confronted with the choice of accepting or ignoring changes. This paper presents a change impact management approach between UML models. It verifies the consistency an...

Domain-specific modelling (DSM) environments enable experts in a certain domain to actively participate in model-driven development. Developing DSM environments need to be cost-efficient, since they are only used by a limited group of domain experts. Different modeldriven technologies promise to allow this cost-efficient development. [1] presented experiences in developing a DSM environment for...

This paper describes a hybrid technical-financial procedure for allocating cost in a large data center. It is designed as a modeling tool to permit IIWHAT-IF" analyses for various configurations, levels of costing. etc. The use of modular programming, independent tables, and matrix output allows the modeler maximum flexibility in allocating cost according to changing technical and financial con...

BACKGROUND Although guidance on good research practice in health economic modeling is widely available, there is still a need for a simpler instructive resource which could guide a beginner modeler alongside modeling for the first time. AIM To develop a beginner's guide to be used as a handheld guide contemporaneous to the model development process. METHODS A systematic review of best pract...
