Approximate methods for optimal replacement, maintenance, and inspection policies
(
Elsevier
, 2015 , Article)
It might be difficult sometimes to derive theoretical and numerical solutions for analytical maintenance modelings due to the computational complexity. This paper takes up several approximate models in maintenance theory, ...
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 ...
Multiple parts process planning in serial–parallel flexible flow lines: part II—solution method based on genetic algorithms with fixed- and variable-length chromosomes
(
Springer London
, 2015 , Article)
Multiple parts process planning (MPPP) is a hard optimization problem that requires the rigor and intensity of metaheuristic-based algorithms such as simulated annealing and genetic algorithms. In this paper, a solution ...
Structural and morphological study of mechanochemically synthesized crystalline nanoneedles of Zr-doped carbonated chlorapatite
(
Elsevier B.V.
, 2015 , Article)
Nanosize Zr-doped carbonated chlorapatite (n-ZCCA) was developed as a novel bioceramic by a ball milling process. Results showed that the microstructural characteristics of the product were affected significantly by the ...
Design development of aggregates cooling systems for hot weather concreting
(
Springer Netherlands
, 2015 , Article)
Using hot aggregates, in concrete production, results in a drop in compressive strength of the produced concrete. Various methods have been proposed for cooling concrete aggregates. This paper proposes new two designs for ...
Evaluation of the Mechanical Properties of AA 6063 Processed by Severe Plastic Deformation
(
Springer US
, 2015 , Article)
In this study, the mechanical properties, including surface hardness, tensile strength, fatigue, and fretting fatigue behavior of AA 6063 processed by equal channel angular pressing as the most efficient severe shear plastic ...
Multiple parts process planning in serial-parallel flexible flow lines: part I—process plan modeling framework
(
Springer London
, 2015 , Article)
In recent years, integrated process planning and scheduling models have been proposed as solutions that can bridge the gap between practical process planning and production scheduling. However, most structures of these ...
Self-organized TiO2 nanotube layer on Ti–6Al–7Nb for biomedical application
(
Elsevier B.V.
, 2015 , Article)
In the present study, a self-organized nanotube TiO2 layer on Ti–6Al–7Nb was fabricated. The influence of acidic electrolytes including glycerol (G) and ethylene glycol (EG) on the anodization, microstructural features and ...
Constitutive analysis for the quantification of hardness decay in a superlattice CrN/NbN hard-coating
(
Elsevier B.V.
, 2015 , Article)
In the present study, a constitutive analysis of the evolution of the mechanical response of a CrN/NbN superlattice coating exposed to high temperature has been performed. Parametric approaches were used to obtain a single ...
Stochastic optimization of the repair shops location problem using particle swarm optimization algorithm
(
American Society of Mechanical Engineers (ASME)
, 2015 , Conference Paper)
The optimization of facility location decisions is critical for the success of a supply chain in a market since it can contribute to long-Term performance of the supply chain. In the last two decades, the number of research ...
