Economic cost models of integrated APC controlled SPC charts
( Taylor & Francis , 2012 , Article)In this paper, an economic cost model is proposed for processes integrating both automatic process control (APC) and statistical process control (SPC) for quality monitoring and control. Both the special cause and common ... -
A framework for condition-based maintenance scheduling
( IEEE , 2012 , Conference Paper)This paper presents a general framework for planning and optimizing Condition-Based Maintenance scheduling. We assume that the hazard function depends, not only on time, but also on the system state which degrades over ... -
Condition-based maintenance for continuously monitored degrading systems with multiple failure modes
( Taylor & Francis , 2013 , Article)This article develops an optimum Condition-Based Maintenance (CBM) policy for continuously monitored degrading systems with multiple failure modes. The degradation of system state is described by a stochastic process, and ... -
Adaptive cumulative sum charts with the adaptive runs rule
( Taylor & Francis , 2013 , Article)Adaptive cumulative sum (ACUSUM) charts, which adjust the reference value dynamically based on estimated shift size, provide good performance in detecting a range of mean shifts. However, when the range is wide, ACUSUM may ... -
Development of a risk assessment tool based on driver behavior and environment
( Intelligent Transport Systems (ITS) , 2014 , Conference Paper)Driver error is the leading cause of vehicle crashes; roadway segment characteristics and environmental conditions follow. However, no safety prediction model has been introduced to estimate risk associated with driver ... -
Three maintenances for age replacement policies
( International Society of Science and Applied Technologies , 2017 , Conference Paper)Preventive replacement policy conducted at a routine time T* has been surveyed extensively in literatures. Another two random replacement times Y1 and Y2 are jointly considered in this paper. We formulate the models of ... -
Re-Thinking Data Strategy and Integration for Artificial Intelligence: Concepts, Opportunities, and Challenges
( MDPI , 2023 , Article Review)The use of artificial intelligence (AI) is becoming more prevalent across industries such as healthcare, finance, and transportation. Artificial intelligence is based on the analysis of large datasets and requires a ... -
Methodological Approach to Assessing the Current State of Organizations for AI-Based Digital Transformation
( MDPI , 2024 , Article)In an era defined by technological disruption, the integration of artificial intelligence (AI) into business processes is both strategic and challenging. As AI continues to disrupt and reshape industries and revolutionize ... -
AI-Powered Innovation in Digital Transformation: Key Pillars and Industry Impact
( MDPI , 2024 , Article)Digital transformation systems generate a substantial volume of data, creating opportunities for potential innovation, particularly those driven by artificial intelligence. This study focuses on the intricate relationship ... -
Multi-sensor degradation data analysis
( Italian Association of Chemical Engineering - AIDIC , 2013 , Conference Paper)Multiple sensors are commonly used for degradation monitoring of critical components. The degradation indicators derived from these sensors are significantly different in terms of scale and interpretation. Since these ... -
ISO 9000:2000 quality management standard: Experience in the state of Qatar
( Inderscience Publishers , 2008 , Article)The main purpose of this paper is to assess the experience of different organisations in the state of Qatar upon adopting the ISO 9000:2000 quality management standard. It is required to report the available motives, ... -
An efficient fault variable identification methodology for distribution-free data stream
( Institute of Industrial Engineers , 2020 , Conference Paper)An efficient fault variable identification methodology for distribution-free data stream -
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, ... -
A model-based crash prediction technique for Chinese roadway segments
( Intelligent Transport Systems (ITS) , 2014 , Conference Paper)This paper presents development and application of a statistical crash prediction model for various types of crashes in Chinese roadway segments. The model is constructed based upon a Negative Binomial Generalized Linear ... -
ISO 9000 performance among the Malaysian companies: The effects of motives
( Inderscience Publishers , 2009 , Article)This paper presents the results of a study to identify the real motives behind ISO 9000 Certification. Towards this goal, a survey of some 300 ISO 9000 certified companies has been carried out for Malaysian manufacturing ... -
Critical success factors of TQM: A UK study
( Inderscience Publishers , 2008 , Article)This paper has presented the results of a study on Critical Success Factors for Total Quality Management (TQM) implementation in UK organisations. A survey instrument (10 Success Factors) developed by Yusof and Aspinwall ... -
Higher order self-adjoint operators with polynomial coefficients
( Texas State University - San Marcos , 2017 , Article)We study algebraic and analytic aspects of self-adjoint operators of order four or higher with polynomial coefficients. As a consequence, a systematic way of constructing such operators is given. The procedure is applied ... -
The Situation of Incommensurability in Strategic Management
( NICCOLO’ CUSANO UNIVERSITY , 2023 , Article)The field of strategic management has witnessed a proliferation of theoretical perspectives following two main paradigms. The two camps roughly correspond, on the one hand, to the "classical" and "neo-classical" approaches, ... -
Nanofluid in tilted cavity with partially heated walls
( Elsevier , 2014 , Article)Lattice Boltzmann Method is applied to investigate the natural convection flow utilizing nanofluids in square enclosure with partially heated walls. The fluid in the cavity is a water-based nanofluid containing different ... -
Population dynamics and predatory impact of the alien jellyfish Aurelia solida (Cnidaria, Scyphozoa) in the Bizerte Lagoon (southwestern Mediterranean Sea)
( Hellenic Centre for Marine Research , 2020 , Article)Understanding the life cycle strategies and predatory impact of alien jellyfish species is critical to mitigate the impact that these organisms may have on local populations, biodiversity, and ultimately on the functioning ...
