Fabrication and characterization of size-selected Cu nanoclusters using a magnetron sputtering source
(
Elsevier B.V.
, 2018 , Article)
Copper nanoclusters are used widely in applications such as glucose and gas sensors. A physical method is used to produce copper nanoclusters utilizing an ultra-high vacuum (UHV) system. Using a quadrupole mass filter ...
A practical solution approach for the green vehicle routing problem
(
Elsevier Ltd
, 2017 , Article)
Green vehicle routing (GVRP) is an active research area that is concerned with the development and analysis of distribution activities with eco-friendly vehicles. We propose a practical solution approach for the GVRP that ...
Elastic properties of chiral, anti-chiral, and hierarchical honeycombs: A simple energy-based approach
(
Elsevier Ltd
, 2016 , Article)
The effects of two geometric refinement strategies widespread in natural structures, chirality and self-similar hierarchy, on the in-plane elastic response of two-dimensional honeycombs were studied systematically. Simple ...
A model and optimization-based heuristic for the operational aircraft maintenance routing problem
(
Elsevier Ltd
, 2016 , Article)
This paper investigates the Operational Aircraft Maintenance Routing Problem (OAMRP). Given a set of flights for a specific homogeneous fleet type, this short-term planning problem requires building feasible aircraft routes ...
Comparisons of replacement policies with periodic times and repair numbers
(
Elsevier Ltd
, 2017 , Article)
Periodic replacement policies modeled with the history of minimal repairs have been studied extensively. However, in the viewpoint of cost rate, there is no literature to compare replacement polices which are carried out ...
Joint optimization of redundancy level and spare part inventories
(
Elsevier Ltd
, 2016 , Article)
We consider a "k-out-of-N"? system with different standby modes. Each of the N components consists of multiple part types. Upon failure, a component can be repaired within a certain time by switching the failed part by a ...
Global reverse supply chain design for solid waste recycling under uncertainties and carbon emission constraint
(
Elsevier Ltd
, 2017 , Article)
The emergence of concerns over environmental protection, resource conservation as well as the development of logistics operations and manufacturing technology has led several countries to implement formal collection and ...
Investigation of effects of temperature cycles on soil-concrete interface behavior using direct shear tests
(
Elsevier B.V.
