Background and Objectives: The selection of the sustainable supplier is important for any industry. Medical centers are not an exception in this case, and selecting the best sustainable supplier is a major step towards increasing their productivity. This paper, using the Data Envelopment Analysis and then using Multi-Attributed Utility Theory as a backup approach to fix errors, attempts t...

This paper présents an application of Multiple Attribute Utility Theory on strategie choices concerning energy transportation. The environmental assessment ofa network reinforcement strategy is emphasized. Our assessment brings about to consider multidimensional variables in MCDM. However, Multi-Attributed Utility Theory (MAUT) cannot, as a practical matter, manage such variables. We therefore ...

A utility function is an important tool for representing a DM’s preference. We adjoin utility functions to multi-objective optimization problems. In current studies, usually one utility function is used for each objective function. Situations may arise for a goal to have multiple utility functions. Here, we consider a constrained multi-objective problem with each objective having multiple utili...

In the last decade, theory of constraint application in project management lead to make a new approach for project scheduling and control as a critical chain. In this paper, a multi-objective optimization model for multi-project scheduling on critical chain is investigated. The objectives include time, cost and quality. In order to solve the problem, a Simulated Annealing algorithm is developed...

in this paper, the radial breathing mode (rbm) frequencies of multi-walled carbon nanotubes (mwcnts) are  obtained based on the multiple-elastic thin shell model. for this purpose, mwcnt is considered as a multiple concentric elastic thin cylindrical shells, which are coupled through van der waals (vdw) forces between two adjacent tubes. lennard-jones potential is used to calculate the vdw forc...

When a new dataset is modeled as an attributed graph or users are not familiar with the data, users may not know what can be retrieved from the attributed graph. Sometimes, users may have some intuition about the query, but how to exactly formulate queries (e.g. what attribute constraints to use) is still unclear to users. In this paper, we propose the idea of attributed path summary. In genera...

to use services transparently in a distributed environment, the utility grids develop a cyber-infrastructure. the parameters of the quality of service such as the allocation-cost and makespan have to be dealt with in order to schedule workflow application tasks in the utility grids. optimization of both target parameters above is a challenge in a distributed environment and may conflict one ano...

Abstract We present network embedding algorithms that capture information about a node from the local distribution over attributes around it, as observed random walks following an approach similar to Skip-gram. Observations neighbourhoods of different sizes are either pooled (AE) or encoded distinctly in multi-scale (MUSAE). Capturing attribute-neighbourhood relationships multiple scales is use...
