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 ...

An experimental investigation into crushing behavior of radially stiffened GFRP composite tubes
(
Elsevier Ltd
, 2014 , Article)
State-of-the-art studies of the crushing of composite tubes reveal different factors affecting their crashworthiness. Of those factors, the geometrical property of the tube is of great interest. In the current study, four ...
Mechanical properties, thermal stability and corrosion behavior of electrodeposited Ni-B/AlN nanocomposite coating
(
Elsevier B.V.
, 2018 , Article)
The present study focuses on the development of Ni-B alloy AlN nanocomposite coating employing a novel electrodeposition technique from citrate bath. The influence of incorporation of AlN particles on structure, thermal ...
Numerical and wind tunnel investigation of Hot Air Recirculation across Liquefied Natural Gas Air Cooled Heat Exchangers
(
Elsevier B.V.
, 2018 , Article)
Air Cooled Heat Exchangers (ACHE)s are used for heat rejection in Liquefied Natural Gas (LNG) plants. Their thermal performance decreases under elevated ambient temperatures and windy conditions as exhaust air recirculates ...
Crushing behavior of a unit cell of CFRP lattice core for sandwich structures’ application
(
Elsevier Ltd
, 2017 , Article)
Sandwich structures made of composites are designed mainly for higher and efficient load capacity. Mostly, the use of composite materials in lattice core sandwich structures is limited to the face sheet; whereas, the core ...
Collapse behavior of thin-walled corrugated tapered tubes under oblique impact
(
Elsevier Ltd
, 2018 , Article)
Thin-walled structures are used in safety applications such as automotive vehicles and locomotives because of their efficient energy absorption, light weight, and reduced manufacturing cost. The performance of these ...
