Constraint satisfaction problems are important in AI. Various distributed and parallel computing strategies have been proposed to solve these problems. In this paper, these strategies are classified as distributed-agent-based, parallel-agent-based, and function-agent-based distributed problem-solving strategies. These different strategies are presented and discussed. Parallel-agentbased strateg...

Original scientific paper Developing a model for citizens’ satisfaction with public services is one of the effective factors for improvement of service quality. In recent years, many studies have been carried out to identify a model for citizens’ satisfaction with public sector services. In the structure of the presented models in the literature, one of the most important issues regarding organ...

Model-based reasoning about a system requires an explicit representation of the system's components and their connections. Diagnosing such a system consists of locating those components whose abnormal behavior accounts for the faulty system behavior. In order to increase the eeciency of model-based diagnosis, we propose a model representation at several levels of detail , and deene three reenem...

The presence of symmetries in a constraint satisfaction problem gives an opportunity for more efficient search. We provide a new way of proving the existence of solution symmetries in all instances of a class of matrix CSPs by way of model transformations. Given a model M and a candidate symmetry σ, the approach first syntactically applies σ to M and then shows that the resulting model σ(M) is ...

The predominant knowledge-based approach to automated model construction, compositional modelling, employs a set of models of particular functional components. Its inference mechanism takes a scenario describing the constituent interacting components of a system and translates it into a useful mathematical model. This paper presents a novel compositional modelling approach aimed at building mod...

nowadays, the concept of sustainable development has found a global application and attracted many parts andbasis of any community. among many factors affecting sustainable developments, educational system is remarkably effective in many ways. the effectiveness of the system is also a function of various factors and components. the managers and their management are one of the components playing...
