Double EWMA-Based Polynomial Quality Profiles Monitoring
(
Wiley
, 2016 , Conference Paper)
Profile monitoring is useful whenever the quality is described by a relationship between a response and one or more of explanatory variables. It is conventional to refer to this relationship as Quality Profile. Despite the ...
Distribution-Free Adaptive Step-Down Procedure for Fault Identification
(
Wiley
, 2016 , Conference Paper)
Identifying the faulty variables of the out-of-control signal in high-dimensional process is an important problem for quality control areas. Even though there have been several procedures for fault variable identifications, ...
First and Last Triggering Event Approaches for Replacement with Minimal Repairs
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Article)
To make effective use of a running system, this paper proposes that, when replacement times could be scheduled at a planned time T of operation, and at a number N of minimal repairs, the newly proposed approach of whichever ...
What is Middle Maintenance Policy?
(
John Wiley and Sons Ltd
, 2016 , Article)
The main purpose of this paper is to propose several new maintenance policies that can be performed at suitable middle times for trivariate preventive maintenance scenarios. Firstly, characteristics and limitations for the ...
An empirical study on lean awareness and potential for lean implementations in Qatar industries
(
Springer-Verlag London Ltd
, 2016 , Article)
In this study, an investigation on the level of recognition of lean concepts, principles, tools, and techniques in different industrial sectors in Qatar was carried out. The general aim of the study was to determine lean ...
Preventive replacement policies with aging failure and third-part damage
(
SciTePress
, 2016 , Conference Paper)
In general, corrosions, degrading the mechanical strength of pipelines gradually with its age in a stochastic way, is the predominant cause of pipeline leaks. In addition, the third-part damage is the leading cause of ...
Replacement policies for periodic damage models
(
International Society of Science and Applied Technologies
, 2016 , Conference Paper)
A new periodic damage model for preventive replacement policies is proposed in this paper, where the damage produced by shocks is only measured at periodic times, without considering the mathematical models of the stochastic ...
Age replacement models: A summary with new perspectives and methods
(
Elsevier Ltd
, 2017 , Article Review)
Age replacement models are fundamental to maintenance theory. This paper summarizes our new perspectives and hods in age replacement models: First, we optimize the expected cost rate for a required availability level and ...
