Markov decision processes are an effective tool in modeling decision-making in uncertain dynamic environments. Since the parameters of these models are typically estimated from data or learned from experience, it is not surprising that the actual performance of a chosen strategy often significantly differs from the designer’s initial expectations due to unavoidable modeling ambiguity. In this p...

In this paper, we present the complete classification of recursive relationships and the criteria that contribute to the structural validity of modeling recursive relationships within the entity-relationship (ER) diagram. Unlike typical other analyses that use only maximum cardinality constraints, we have used both maximum and minimum cardinality constraints in defining the properties and their...

Solving software evaluation problems is a particularly difficult software engineering process and many different often contradictory criteria must be considered in order to reach a decision. This paper presents ESSE, a prototype expert system for software evaluation that embodies various aspects of the Multiple-Criteria Decision Aid (MCDA) methodology. Its main features are the flexibility in p...
