Recently there has been a growing interest in non-linear aggregation models to represent the preferences of a decision maker in a multicriteria decision problem. Such models are expressive as they are able to represent synergies (positive and negative) between attributes or criteria, thus modeling different decision behaviors. They also make it possible to generate Pareto-optimal solutions that...

Searching for relevant information on the World Wide Web is often a laborious and frustrating task for casual and experienced users. To help improve searching on the Web based on a better understanding of user characteristics, we address the following research questions: What kind of information would rough set theory shed on user’s web behavior? What kind of rules can we extract from a decisio...

A crucial decision within component-based modeling and simulation is the choice of the criterion or criteria to be used in decomposing the system. Many experiences with combat simulation systems indicate, first, that the optimal choice depends on the driving forces behind the decomposition or the goals that should be achieved by using components instead of monolithic systems. Second, the common...

one of the most important steps involved in mining operations is to select an appropriate extraction method for mine resources. after choosing the extraction method, it is usually impossible to replace it with another one because it may be so expensive that implementation of the entire project could be economically impossible. choosing a mining method depends on the geological and geometrical c...

emergency department has become a useful way to the access to hospital and it is a subject of study for many researchers. the research developed in this paper aims to improve the performance of the emergency department(ed) of sfax hospital. simulation results showed that to manage to increase the number of treated patients and thus to decrease the patient cycle time, it is important to add a sp...

the expansion of major cities regardless of the scientific planning principles has led to theemergence of negative urban development impacts in iran such as the degradation of natural resources andvarious forms of pollution. undoubtedly, urban rivers can enhance the ecological value of the earth to anoptimal extent. however, to benefit from these potentials, appropriate planning looks inevitabl...

Enterprise Architecture (EA) modeling languages can express the business-to-IT-stack for an organization, showing how changes in the IT landscape impact business aspects and vice versa. Yet EA languages provide only the final architectural design, not the rationale behind this design. In earlier work, we presented the EA Anamnesis approach for EA rationalization. We discussed how EA Anamnesis f...

The ornamental and medicinal saffron with high economic value encompasses a great share of non-oil exports in Iran. As a result, identification of suitable areas for saffron cultivation in Ardabil province located in northwestern part of Iran necessitate effective planning for expanding cultivation and production of this product. Given the effect of various environmental factors on growth and y...
