A new compact formulation for the daily crew pairing problem
(
INFORMS Inst.for Operations Res.and the Management Sciences
, 2019 , Article)
The daily crew pairing problem (DCPP) seeks to generate a set of minimal-cost pairings that covers all the planned daily flights while complying with a variety of labor regulations, safety rules, and policies of the airline. ...
A preemptive bound for the Resource Constrained Project Scheduling Problem
(
Springer US
, 2014 , Article)
The Resource Constrained Project Scheduling Problem is one of the most intensively investigated scheduling problems. It requires scheduling a set of interrelated activities, while considering precedence relationships, and ...
An adaptive step-down procedure for fault variable identification
(
Taylor & Francis
, 2015 , Article)
In a process with a large number of process variables (high-dimensional process), identifying which variables cause an out-of-control signal is a challenging issue for quality engineers. In this paper, we propose an adaptive ...
Optimal replacement last with continuous and discrete policies
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Article)
This paper proposes age and periodic replacement last models with continuous, and discrete policies. That is, an operating unit is replaced preventively at time T of operation as a strategic policy, or at a number N of ...
Abandoned petroleum wells as sustainable sources of geothermal energy
(
Elsevier Ltd
, 2014 , Article)
A reliable heat transfer model was developed to determine the performance of a double pipe heat exchanger retrofitted to an abandoned petroleum well. The proposed model is compared against an analytical heat transfer model ...
Effect of Interlayer Thickness on Joint Formation Between Ti-6Al-4V and Mg-AZ31 Alloys
(
Springer New York LLC
, 2014 , Article)
The joining of a Ti-6Al-4V alloy to a Mg-AZ31 alloy was performed using Ni electroplated coatings during the TLP bonding process. In this work, different coating thicknesses were used ranging from 1 to 20 μm. The effect ...
Thermo elastic analysis of functionally graded rotating disks with temperature-dependent material properties: uniform and variable thickness
(
Springer Science+Business Media, B.V.
, 2009 , Article)
A thermo elastic analysis is presented for axisymmetric rotating disks made of functionally graded material (FGM) with variable thickness. Material properties are assumed to be temperature-dependent and graded in the radial ...
Multivariate statistical process control charts based on the approximate sequential ?2 test
(
Taylor and Francis Ltd.
, 2014 , Article)
Similar to the univariate CUSUM chart, a multivariate CUSUM (MCUSUM) chart can be designed to detect a particular size of the mean shift optimally based on the scheme of a sequential likelihood ratio test for the noncentrality ...
Enhanced simulated-annealing-based algorithms and their applications to process planning in reconfigurable manufacturing systems
(
Elsevier, Ltd
, 2012 , Article)
Capabilities of enhanced simulated-annealing-based algorithms in solving process planning problems in reconfigurable manufacturing are investigated. The algorithms are enhanced by combining variants of the simulated annealing ...
Materials and design issues for military helmets - Chapter 6
(
Woodhead Publishing
, 2012 , Book chapter)
Abstract: As weaponry technology has advanced, the ballistic threat to humans has increased significantly. As well as the military, civilians who are exposed to these threats as part of their everyday work require adequate ...
