A fuzzy AHP approach to evaluating machine tool alternatives
(Springer, 2006)
Selecting process of a machine tool has been very important issue for companies for years because the improper selection of a machine tool might cause of many problems affecting negatively on productivity precision flexibility ...
Cad software evaluation for product design to exchange data in a supply chain network
(ExcelingTech Publishers, 2015)
The sharing information in a supply chain environment especially CAD models and drawings are so important companies. So the selection of the most satisfying computer-aided design (CAD) software which enables to exchange ...
An analytic network process-based approach to concept evaluation in a new product development environment
(Taylor & Francis, 2007)
Selecting the best product concept is one of the most critical tasks in a new product development (NPD) environment. Making decisions at this stage becomes very difficult due to imprecise and uncertain product requirements. ...
Conformal and generalized concircular mappings of Einstein-Weyl manifolds
(2010)
In this article after giving a necessary and sufficient condition for two Einstein-Weyl manifolds to be in conformal correspondence we prove that any conformal mapping between such manifolds is generalized concircular if ...
A numerical study of the laminar necklace vortex system and its effect on the wake for a circular cylinder
(Amer Inst Physics, 2012)
Large eddy simulation (LES) is used to investigate the structure of the laminar horseshoe vortex (HV) system and the dynamics of the necklace vortices as they fold around the base of a circular cylinder mounted on the flat ...
An intelligent approach to machine tool selection through fuzzy analytic network process
(Springer, 2011)
In this study we utilize analytic network process (ANP) a more general form of AHP for justifying stand-alone machine tools out of available alternatives in market due to the fact that AHP cannot accommodate the variety ...
An integrated approach to evaluating assembly-line design alternatives with equipment selection
(Taylor & Francis Ltd, 2011)
The design and implementation of assembly-line systems have been critical issues for companies since the first assembly-line was started at the Ford Highland Plant in 1913. From that time onwards most companies have met ...
Forecasting Models For Daily Natural Gas Consumption Considering Periodic Variations And Demand Segregation
(Elsevier Ltd, 2020)
Due to expensive infrastructure and the difficulties in storage, supply conditions of natural gas are different from those of other traditional energy sources like petroleum or coal. To overcome these challenges, supplier ...
On the Time Shift Phenomena in Epidemic Models
(Frontiers Media Sa, 2020)
In the standard Susceptible-Infected-Removed (SIR) and Susceptible-Exposed-Infected-Removed (SEIR) models, the peak of infected individuals coincides with the inflection point of removed individuals. Nevertheless, a survey ...
Maximal linear subspaces of strong self-dual 2-forms and the Bonan 4-form
(Elsevier Science Inc, 2011)
The notion of self-duality of 2-forms in 4-dimensions plays an eminent role in many areas of mathematics and physics, but although the 2-forms have a genuine meaning related to curvature and gauge-field-strength in higher ...
