This paper shows that a qualitative analysis can always be used in evaluating a model's validity both in general and compared to other hypothesized models. The analysis relates the sign patterns and possibly other information of hypothesized structural arrays to the sign pattern of the estimated...

The use of semantic space to control the dimension of economic and physical variables in the verification of economic mathematical models is proposed. The basis of the semantic space is the vector representation of dimension values. For construction of semantic space the classification of units...

Software development projects have been blamed for being behind schedule, cost overruns, and the delivery of poor quality product. This paper presents a simulation model of a data warehouse to evaluate the feasibility of different software development controls and measures to better manage a...

The meteorological model Regional Atmospheric Modeling System (RAMS) in its version 4.4 has been applied operationally within the Valencia Region. The model output is being used as support for a heat-wave warning system, a wind forecasting system for fire warnings and prevention, and for general...

Purpose – The paper aims to introduce a model for measuring individual performance named Workforce Competency Model (WFCM). Notable aspects of the model including its validation/verification are explored and presented by means of a case study. Design/methodology/approach – The model is...

The main purpose of this paper is to demonstrate an empirical approach to social simulation. The systems and the behaviour of middle-level managers of a real company are modelled. The managers' cognition is represented by problem space architectures drawn from cognitive science and an...
