introduction: one of the types of hospital management information systems is decision support information system (dsis). this system uses decision-making models and databases for preparing specific information to support their semi-structured or unstructured decisions. the present study aimed to design a decision dsis model for board of trustees of ayatollah kashani hospital, shahrekord, iran. ...

The article proposes the creation of an effective system for detecting and responding to external influences in order minimize consequences breaching protection cloud virtual resources a timely manner. Mathematical models have been improved ensure software-configured networks, namely: mathematical model impact attack on resources, assessing state choosing countermeasure based complex indicator ...

Mainstream object-oriented programming (OOP) languages such as Java, C#, C++ and Scala are all almost entirely nominally-typed. NOOP is a recently developed domain-theoretic model of OOP that was designed to fully include nominal information found in nominally-typed OOP. This paper compares NOOP to the most widely known domain-theoretic models of OOP, namely, the models developed by Cardelli an...

Here, we collect two parts of a research project on the pedestrian flow modeling. Rapid growth in the volume of public transport and the need for its reasonable, efficient planning have made the description and modeling of transport and pedestrian behaviors as important research topics in the past twenty years. First, we present a macroscopic model for the pedestrian flow based on continuum mec...

In this paper, the common centralized DEA models are extended to the bi-level centralized resource allocation (CRA) models based on revenue efficiency. Based on the Karush–Kuhn–Tucker (KKT) conditions, the bi-level CRA model is reduced to a one-level mathematical program subject to complementarity constraints (MPCC). A recurrent neural network is developed for solving this one-level mathematica...

This paper addresses a new version of the exible ow line prob- lem, i.e., the budget constrained one, in order to determine the required num- ber of processors at each station along with the selection of the most eco- nomical process routes for products. Since a number of parameters, such as due dates, the amount of available budgets and the cost of opting particular routes, are imprecise (fuzz...
