A Generalized Policy Support System and Its Hierarchy Semantics
نویسندگان
چکیده
One common characteristic of many Policy Support Systems (PSSs) is their dependency on the concept of hierarchy. Hierarchy does not need to be limited to a hierarchy of roles (subject centric) as in traditional Role-Based Access Control (RBAC). Instead, it can be applied to other aspects of PSS such as object, environment, purpose and so on. In this paper, we propose a new generalized model for PSS . The model unifies Generalized Role-Based Access Control (GRBAC) and Enterprise Privacy Practices (E-P3P) policy support systems and generalizes their hierarchy semantics.

Making Decision Support System for Utilization of Biogas in Iran
The use of renewable energy sources is often suggested to be a good solution for climate change and the dependency to fossil fuel. Biogas utilization is a one of these promising options that can mitigate these problems since biogas is produced by the fermentation of waste, so is rich in methane and has the same characteristics as natural gas. Biogas has increasingly been noticed in different co...
متن کاملConstructive design of a hierarchy of semantics of a transition system by abstract interpretation
We construct a hierarchy of semantics by successive abstract interpretations. Starting from the maximal trace semantics of a transition system, we derive the big-step semantics, termination and nontermination semantics, Plotkin’s natural, Smyth’s demoniac and Hoare’s angelic relational semantics and equivalent nondeterministic denotational semantics (with alternative powerdomains to the Egli-Mi...
متن کاملModeling and development of a decision support system for supplier selection in the process industry
This paper presents the development of a model based decision support system with a case study on solving the supplier selection problem in a chemical processing industry. For the evaluation and selection of supplier, the analytical hierarchy process (AHP) and grey relational analysis (GRA) were used. The intention of the study is to propose an appropriate platform for process industries in ...
متن کاملThe optimum support selection by using fuzzy analytical hierarchy process method for Beheshtabad water transporting tunnel in Naien
The engineers can frequently encounter with the situation to select the optimum option among the alternatives related with tunneling operations. The optimum choice can be selected by the experienced engineers taking into consideration their judgment and intuition. However, decision-making methods can offer to the engineers to support their optimum selection for a particular application in a sci...
