The ݇-level Uncapacitated Facility Location (UFL) problem is a generalization of the UFL and the ݇-median problems. A significant shortcoming of the classical UFL problem is that often a few very distant customers, known as outliers, can leave an undesirable effect on the final solution. This deficiency is considered in a new variant called UFL with(More)

Introduction Methodology Controlled Experiment Study The Role of People in RE Of the three Ps, process, product, and people, in software engineering, people have been least scrutinized. Boehm observed that the quality of(More)
The emerging field of semantic web technologies promises new stimulus for Method Engineering. However, since the underlying concepts of the semantic web have a long tradition in the knowledge engineering field, it is sometimes hard for method engineers to overlook the variety of ontology-enabled approaches to Method Engineering. In this paper we present an(More)
[Background] One factor that seems to influence an individual's effectiveness in requirements engineering activities is her knowledge of the problem being solved, i.e., domain knowledge. While in-depth domain knowledge enables a requirements analyst to understand the problem easier, she can fall for tacit assumptions and might overlook obvious issues.(More)
