In this paper, we present a multicriteria-based framework for comparing Workflow modelling tools. Our model uses the nature of the process and the collection of workflow patterns as evaluation criteria. Specifically, our goal is to use ELECTRE method to rank the tools from best to worst according to their ability to support the workflow patterns. Our approach is justified by the fact that none ...

Multi criteria decision making (MCDM) methods like analytic hierarchy process, ELECTRE and multi-attribute utility theory are critically studied. They have irregularities in terms of the reliability of ranking of the best alternatives. The Routing Decision Support (RDS) algorithm is trying to improve some of their deficiencies. This paper gives a mathematical verification that the RDS algorithm...

The design of a CBR system involves the use of similarity metrics. For many applications, various functions can be adopted to compare case features and to aggregate them into a global similarity measure. Given the availability of multiple similarity metrics, the designer is hence left with two options in order to come up with a working system: Either select one similarity metric or try to combi...

The VIKOR method was developed to solve MCDM problems with conflicting and noncommensurable (different units) criteria, assuming that compromising is acceptable for conflict resolution, the decision maker wants a solution that is the closest to the ideal, and the alternatives are evaluated according to all established criteria. This method focuses on ranking and selecting from a set of alternat...

employer organizations have increasingly interested in outsourcing their projects in the form of public-private partnership (ppp) due to various reasons such as compromising the resource limitations, entering new technologies to the organization and reducing risk. choosing the private sector as one of the most basic steps in the formation of ppp is of great importance. the present study aims to...

The objective of this paper is to devise a strategy for developing a flexible tool to efficiently install a marine energy farm in a suitable area. The current methodology is applied to marine tidal current, although it can be extended to other energy contexts with some adaptations. We introduce a three-step approach that searches for marine farm sites and technological solutions. The methodolog...

Agents and multi-agent systems constitute nowadays a very active field of research. This field is very multidisciplinary since it is sustained by Artificial Intelligence, Distributed Systems, Software Engineering, etc. In most agent applications, the autonomous components need to interact. They need to communicate in order to solve differences of opinion and conflicts of interest. They also nee...

Outsourcing plays an important role in the success of organizations. One of the risks associated with outsourcing is inappropriate contractor selection which significantly influences the implementation of projects in terms of time, quality, and cost. In this study, we applied multi-criteria decision-making techniques in order to determine the best contractor using criteria such as reputation, o...
