For a prediction problem of a given target feature in a large causal network under external interventions, we propose in this paper two partial orientation and local structural learning (POLSL) approaches, Local-Graph and PCD-by-PCD (where PCD denotes Parents, Children and some Descendants). The POLSL approaches are used to discover the local structure of the target and to orient edges connecte...

This work contributes to the practice of healthcare system modelling, by presenting an urgent issue: the growing process of integrated healthcare supply networks in reducing public healthcare systems’ annual expenses and improving performance. Various critical aspects affect the strategic design and development of healthcare logistic networks in practice. The conceptual discussion is empiricall...

one of the most important issues always facing banks and financial institutes is the issue of credit risk or the possibility of failure in the fulfillment of obligations by applicants who are receiving credit facilities. the considerable number of banks’ delayed loan payments all around the world shows the importance of this issue and the necessary consideration of this topic. accordingly, many...

background : in medical studies, when the joint prediction about occurrence of two events should be anticipated, a statistical bivariate model is used. due to the limitations of usual statistical models, other methods such as artificial neural network (ann) and hybrid models could be used. in this paper, we propose a hybrid artificial neural network-genetic algorithm (ann-ga) model to predictio...

In this paper, we study the network design problem with relays considering network survivability. This problem arises in telecommunications and logistic systems. The design problem involves selecting two edge-disjoint paths between source and destination node pairs and determining the location of the relays in the network to minimize the network cost. A constraint is imposed on the distance tha...

accessibility is one of the important factors in public open space design and the creation of equitable neighborhoods. limitations caused by physical disabilities should not be a barrier for accessing desired spaces and people must be able to live with the greatest possible independence regardless of mobility limitations. the purpose of this paper was to identify the inclusive criteria of pedes...
