Effective resource requirement forecasting is necessary to reduce the escalating cost of care by ensuring optimum utilization and availability of scarce health resources. Patient hospital length of stay (LOS) and thus resource requirements depend on many factors including covariates representing patient characteristics such as age, gender, and diagnosis. We therefore propose the use of such covariates...
Selecting an appropriate conductor joint method is essential by considered conducting wire safety performance. The Analytical Hierarchy Process (AHP) method is usually used for solving multi-criteria decision-making problems. However, the traditional AHP method is incapable of handling the uncertainty and vagueness involving the mapping of one's preference to an exact number or ratio. In this paper,...
To support the decision-making on coordination process for aviation projects, a multi-project priority assessing method based on fuzzy comprehensive evaluation is presented. A bi-layered hierarchy model is introduced to determine the set of factors for priority assessment at first. Then the weight of each involved factor is calculated through analytic hierarchy process (AHP), which merges human experts'...
The conventional analytic hierarchy process (AHP) has the drawback of its invariable weights system (IWS) and the composite ranking approaches based on IWS, incapable of reflecting intrinsic characteristics of complex evaluation issues, such as nonlinearity, emergence, etc. To overcome the above drawback, with the idea of weight varying adopted, an improved ranking approach to AHP alternatives based...
This paper presents the application of paraconsistent logic to the decision-making multi-criteria method AHP - analytic hierarchy process. The model uses pairwise comparison matrixes and multiple specialistspsila evaluations, to calculate the degree of inconsistency of each analyzed alternative. With this tool, decision-makers can acquire greater confidence in decisions based on feeling, subjective...
Trust management has been considered an important factor in Grid computing security. Grids require a secure way to establish trust in their participants without requiring continuous intervention by the system administrators. This paper describes trust management in Grid computing systems and its use in evaluation environments to update the trust levels. This approach can be incorporated in Grid security...
Supply chain transformation is an emerging service area in the market which aims at helping clients improve their operational efficiency and reduce costs. As a generic technique for the analysis of complex and dynamic systems, simulation could play an important role in this field. This paper presents a case study showing how simulation could be the key enablement for a supply chain transformation...
