Modelling contexts in the Or-BAC model
19th Annual Computer Security Applications Conference, 2003. Proceedings., 2004As computer infrastructures become more complex, security models must provide means to handle more flexible and dynamic requirements. In the organization based access control (Or-BAC) model, it is possible to express such requirements using the notion of context.

Models, models, models: a deflationary view
Synthese, 2018In this essay, I first consider a popular view of models and modeling, the similarity view. Second, I contend that arguments for it fail and it suffers from what I call “Hughes’ worry.” Third, I offer a deflationary approach to models and modeling that avoids Hughes’ worry and shows how scientific representations are of apiece with other types of ...

Design Issues, 2014
Business model design does not always produce a “design” or “model” as the expected result. However, when designers are involved, a visual model or artifact is produced. To assist strategic managers in thinking about how they can act, the designers’ challenge is to combine both strategy and design notions. The intent of this article is to gain a better

Model Transformations with Reference Models
2007In this paper we introduce and explore an extension to the existing paradigm of model transformation. Specifically, we extend existing model transformation approaches by considering reference models and human input as important sources for and during model transformation.

On Models, Modelling, and the Exemplary
2000Abstract We may recall the statement that to imitate is to follow the example of exemplary models. The method is a central characteristic of the exemplary society. But learning from models is more than a simple pedagogical method. It represents the culmination of an imitative-repetitive culture. The Confucian view assumes that men are

Business Modelling Is Not Process Modelling
2000Innovative e-business projects start with a design of the e-business model.We often encounter the view, in research as well as industry practice, that an e-business model is similar to a business process model, and so can be specified using UML activity diagrams or Petri nets. In this paper, we explain why this is a misunderstanding.

Models, Models and More Models
2011This chapter investigates the main approaches used to analyze competition for investment through investment incentives. We begin with general approaches to assessing the use of incentives, including Prisoners’ Dilemma, models in the Tiebout (1956) tradition, incentives as necessary to generate spillovers and the global vs. local efficiency matrix. Next,
