Modelling Frameworks: The Essential Link Between Models and Methodologies
نویسنده
چکیده
The representation of abstractions through models is an over-arching theme in system development methodologies. In order to express all the subtleties of complex systems, methodologies suggest the use of several models, with each representing some aspects of the universe of discourse. Unfortunately, there is no universal agreement about which aspects of the existing and/or the new information system should be modelled and the notations that should be used to model them. This paper proposes a generalised three dimensional modelling framework that can be used to make sense of the wide variety of models and modelling notations used within system development methodologies.

Nowadays one of the biggest problems of IT organizations in less developed countries is paying too much attention to infrastructure and technology of organizations. This is due to the point that many managers in organizations believe that existence of IT infrastructure and technology by itself is a sign of maturity of an organization. Although technical facilities and infrastructure such as net...

متن کاملProbit-Based Traffic Assignment: A Comparative Study between Link-Based Simulation Algorithm and Path-Based Assignment and Generalization to Random-Coefficient Approach
Probabilistic approach of traffic assignment has been primarily developed to provide a more realistic and flexible theoretical framework to represent traveler’s route choice behavior in a transportation network. The problem of path overlapping in network modelling has been one of the main issues to be tackled. Due to its flexible covariance structure, probit model can adequately address the pro...

The aim of this paper is to consider what constitutes agent-based modelling (ABM) and how this can relate to archaeological reasoning. The development and construction of ABM models is an essential prerequisite for most archaeological reasoning. Both directly and indirectly, archaeologists are making extensive use of ideas and methods in applications that derive from archaeological, anthropolog...
متن کاملLink Types as Enablers of Semantic Navigation in Standard-Based Web Learning Systems
The concept of link in hypermedia systems and models provides an abstract and generic mean to arbitrarily interconnect nodes and contents. As a consequence of the loose semantics of the general plain concept of link, different types of links have been proposed for different purposes [Kopak, 1999], including the definition of aggregation and generalization relationships [Garg, 1988] and the expl...
