- The problem addressed in this paper is how to utilise the concept of total quality maintenance (TQMain) to develop an integrated VBM (vibration-based maintenance) for detecting deviations in the machine condition and product quality (technical specifications), before the machine starts manufacturing defective items. Concepts of TQMain and integrated VBM are discussed. A technical analysis is conducted to identify quality problem cause roots when manufacturing crankshafts in Volvo, Motor, Skövde, Sweden. A factorial experiment is conducted to assess the effect and significance of the suspected causes. Vibration measurements from 7 points are collected. The major conclusion of this study is; when using an effective, e.g. on the basis of TQMain concept, integrated VBM, deviations in product quality can be detected at an earlier stage than that when using usual quality control diagrams. Manufacturing defective items can be reduced dramatically (or prevented) which will eliminate bad quality- related losses.

- PurposeConsidering the importance and the broad applications of the Fourth Industrial Revolution in various organizations and industries and enjoying the many benefits of this digital transformation framework, organizations need to measure their Industry 4.0 readiness as a starting point and take steps to achieve the strategic goals of Industry 4.0. This study aims to design a comprehensive and practical model that can determine Industry 4.0 readiness level, allowing organizations to implement and exploit technological constituents of this phenomenon.Design/methodology/approachA systematic literature review (SLR) methodology was used to evaluate and summarize a clear and comprehensive literature overview of Industry 4.0 readiness models and to certify the validity and transparency of the review process. After reviewing 71 articles and survey and then the consensus of Industry 4.0 experts, the 10 dimensions of the 4.0 Industry readiness model were finalized with their indicators having the most frequency in the published articles and models.FindingsThe application of the SLR to the development of the new Industry 4.0 readiness model which includes 10 dimensions and 37 indicators and can assess the Industry 4.0 readiness of firms and industries accurately and effectively.Research limitations/implicationsAn extensive review of the previous literature yielded the current Industry 4.0 readiness model. The comprehensiveness of this model leads to its wide application in different companies. Future research suggestions are presented at the end of the manuscript.Practical implicationsThe concept of the Fourth Industrial Revolution and the application of its technologies are vague and complicated for many organizations and managers, while the need to implement the components and technologies of Industry 4.0 is essential to achieve organizational goals. The presented readiness model helps companies to measure their readiness to enter the Fourth Industrial Revolution and achieve long-term goals.Originality/valueIn this study, an attempt was made to examine the Industry 4.0 readiness models thoroughly and extensively and identify their different approaches. Finally, a comprehensive and multi-dimensional readiness model is presented to assess the position of organizations in order to enter Industry 4.0.

Tidskriftsartikel (refereegranskat)abstract
- Product development projects can be utilized to create not only new products or services but also competitively important capabilities on how to work with product development. The resulting capabilities can be, and often are, as important as the product itself. Although there is potential for an organization to improve product development performance, most organizations can learn even more from their development experiences. A reliance on post‐project reviews to share knowledge across projects is doomed to fail, since it usually is of low priority and does not capture the complexity of development projects. The aim of this research is to investigate what organizations can do to reduce the effect of losing valuable experience gained in product development projects.Design/methodology/approachA multiple case study approach, using both qualitative and quantitative data, is used to perform a study of two high‐tech product development organizations with respect to their inter‐project improvement activities. A framework concerning inter‐project improvement is presented, containing concepts such as levels of learning, improvement content, and axes of improvement.FindingsTo avoid losing valuable experience, an organization should use multiple strategies to share knowledge across projects. Examples of successful strategies are to use a well‐established product development process, professional full‐time project managers as well as modularization of the product.Originality/valueAlthough research on organizational learning in product development has increased significantly during the last few years, this research contributes to a deeper understanding of inter‐project improvement by combining perspectives from quality management, organizational learning, and knowledge management.

Continuous improvement : challenges for the project-based organization
- 2018
-
Ingår i: International Journal of Quality & Reliability Management. - : Emerald Group Publishing Limited. - 0265-671X .- 1758-6682. ; 5:7, s. 1306-1320

Tidskriftsartikel (refereegranskat)abstract
- PurposeThere are limited studies of Continuous improvement from the perspective of a project-based organization (PBO). Hence, this article explores challenges that PBOs may encounter when applying Continuous improvement.Design/methodology/approachAn exploratory and qualitative approach has been used, involving six management teams in six different project-based organizations, using focus groups interviews as data collecting method.FindingsA high degree of autonomy among project managers seems to limit a collective approach to project management in PBOs. As a consequence the overall PBO performance becomes subordinate to the individual project performance – an approach opposite to that of Continuous improvement. Further, the management teams themselves seem to uphold a project focus, also complicating improvement initiatives from a PBO perspective.Research limitations/implicationsThe management teams have been the unit of analysis, where the PBOs mainly conduct projects in an engineering and construction context, and are located in the same country and region. This approach enables the thorough study of a phenomenon, while preconditions for generalization are limited. However, the findings could be used by researchers as a basis for more in-depth studies of specific challenges, and for making surveys to obtain generalization of results.Practical implicationsThe results can induce awareness and understanding of different challenges if applying Continuous improvement in a PBO, hence a starting point for finding ways to overcome these challenges.Originality/valueThe article contributes to an increased understanding of challenges that PBOs may encounter when applying Continuous improvement, confirming and presenting additional findings compared to previous studies.

Tidskriftsartikel (refereegranskat)abstract
- Purpose - To define availability importance measures in order to calculate the criticality of each component or subsystem from availability point of view and also to demonstrate the application of such importance measures for achieving optimal resource allocation to arrive at the best possible availability. Design/methodology/approach - In this study the availability importance measures of a component are defined as a partial derivative of the system availability with respect to the component availability, failure rate, and repair rate. Analyses of these measures for a crushing plant are performed and the results are presented. Furthermore, a methodology aimed at improving the availability of a system using the concept of importance measures is identified and demonstrated by use of a numerical example.Findings - The availability importance measure of a component/subsystem is an index which shows how far an individual component contributes to the overall system availability. The research study indicates that the availability importance measures could be applied in developing a strategy for availability improvement. The subsystem/component with the largest value of importance measure has the greatest effect on the system availability. Research limitations/implications -The result of availability improvement strategy is demonstrated using only a hypothetical example.Practical implications - Using of availability importance measures will help managers and engineers to identify weaknesses and indicate modifications which will improve the system availability.Originality/value - This paper presents the concept of availability importance measure for a component/subsystem. It also introduces some availability importance measures based on failure rate, mean time between failures (MTBF), and repair rate/mean time to repair (MTTR) of a component /subsystem. The concept of importance measures are used to prioritize the components or subsystems for the availability improvement process.

Review and discussion of production assurance program
- 2010
-
Ingår i: International Journal of Quality & Reliability Management. - : Emerald. - 0265-671X .- 1758-6682. ; 27:6, s. 702-720

Tidskriftsartikel (refereegranskat)abstract
- Purpose - The purpose of this paper is to review, discuss and further develop the production assurance (PA) concept; and to define and describe a typical production assurance program (PAP) and its elements. Design/methodology/approach - An explorative literature study covering PA and dependability concept was carried out on contemporary literature. During the course of the study, meetings and discussions with a number of experts in Sweden and Norway were performed. Different types of data and examples from the oil and gas industries are used to illustrate and support the discussions. Findings - This paper indicates that the concept of PA helps the decision maker to estimate whether a production plant is able to meet customer requirements, as it provides information about the production plant's delivery capacity, production rate and ability to deliver according to design or customer demands. PAP can provide a basis for effective production control. Research limitations/implications - The material analysed was mainly related to the oil and gas industry. However, the findings and discussion can be transferred to other areas of application, such as mine production plants and chemical process plants. Practical implications - A PAP is a valuable tool for production plant managers and engineers, not only for documenting a production plant's performance, but also for providing decision support for the development and optimization of the production plant to improve the plant's performance and reduce risk and uncertainties. Originality/value - In this paper the concept of dependability is extended to include capacity performance and customer requirements or market demand, which provides a measure for delivery assurance or plant production performance in relation to customer requirements. This paper also develops a generic PAP to achieve a high level of delivery assurance.

- Purpose – The purpose of this paper is to point out the potential for further theorizing of the concept of mindfulness, by extending and nuancing present accounts of East-West dichotomies in relation to the concept. Design/methodology/approach – The paper takes the form of a literature review. Findings – Dichotomies of Western and Eastern approaches to mindfulness can be extended by analyzing key elements of their respective philosophies, notably through their different views on permanence versus impermanence, uni-directional versus mutual causality and conceptual versus non-conceptual knowledge. Through these key elements, a more nuanced picture of Eastern and Western elements can be identified in relation to quality management research and practice. The dual roots in Eastern and Western contexts point at the potential for further theorizing inherent in the concept of mindfulness. Originality/value – This paper takes a broad and nuancing view on present dichotomies of Eastern and Western accounts on mindfulness and points at the concept’s future potential.

Exploring research on quality and reliability management through text mining methodology
- 2017
-
Ingår i: International Journal of Quality & Reliability Management. - 0265-671X .- 1758-6682. ; 34:7, s. 975-1014

Tidskriftsartikel (refereegranskat)abstract
- Purpose - The purpose of this paper is to explore and describe research presented in the International Journal of Quality & Reliability Management (IJQRM), thereby creating an increased understanding of how the areas of research have evolved through the years. An additional purpose is to show how text mining methodology can be used as a tool for exploration and description of research publications.Design/methodology/approach - The study applies text mining methodologies to explore and describe the digital library of IJQRM from 1984 up to 2014. To structure and condense the data, k-means clustering and probabilistic topic modeling with latent Dirichlet allocation is applied. The data set consists of research paper abstracts.Findings - The results support the suggestion of the occurrence of trends, fads and fashion in research publications. Research on quality function deployment (QFD) and reliability management are noted to be on the downturn whereas research on Six Sigma with a focus on lean, innovation, performance and improvement on the rise. Furthermore, the study confirms IJQRM as a scientific journal with quality and reliability management as primary areas of coverage, accompanied by specific topics such as total quality management, service quality, process management, ISO, QFD and Six Sigma. The study also gives an insight into how text mining can be used as a way to efficiently explore and describe large quantities of research paper abstracts.Research limitations/implications - The study focuses on abstracts of research papers, thus topics and categories that could be identified via other journal publications, such as book reviews; general reviews; secondary articles; editorials; guest editorials; awards for excellence (notifications); introductions or summaries from conferences; notes from the publisher; and articles without an abstract, are excluded.Originality/value - There do not seem to be any prior text mining studies that apply cluster modeling and probabilistic topic modeling to research article abstracts in the IJQRM. This study therefore offers a unique perspective on the journal's content.

Tidskriftsartikel (refereegranskat)abstract
- Historically, a theoretical framework has been established to judge whether a process is capable or not. These studies, called process capability studies, have received both positive and negative comments. Both researchers and practitioners have indicated that the concept of process capability studies is often misused in practice. This article aims to identify and quantify this misuse, and when it is severe, try to provide some explanations of its origin. The survey presented is primarily based on questionnaires and carried out among 97 Swedish organisations where process capability studies are used regularly. It shows that there is often a gap between theory and practice concerning process capability studies. The article also provides some possible answers to why the gap exists. It has been found that the gap between theory and practice can be explained by management issues, practical problems, conservative personal attitudes and methodological aspects. Based on the results, some suggestions for successfully implementing and using process capability studies are presented.

Hazards and quality control in humanitarian demining
- 2018
-
Ingår i: International Journal of Quality & Reliability Management. - 0265-671X .- 1758-6682. ; 35:4, s. 897-913

Tidskriftsartikel (refereegranskat)abstract
- Purpose: The purpose of this paper is to discuss the adequacy of International Mine Action Standards 09.20 (IMAS 09.20) and the used standards ISO 2859 in the context of demining. Design/methodology/approach: The authors show how the actual quality level acceptable quality limit (AQL) significantly affects the average total quality cost for one lot with a single sampling plan and, consequently, the average total quality cost, and as AQL increases, the cost of rejecting a lot and the cost of sampling increase. Findings: The sampling plans for demining are not always optimal given economical and other concerns and that other mechanisms should be considered. Practical implications: Addressing opportunity costs for adopting wide samplings plans instead of clearing uncleared land per default, as well as balancing producer and consumer consequences seems, therefore, to be highly relevant from a socio-economical perspective. Originality/value The general understanding of quality management and the systems involved are limited within the mine action sector. IMAS and most national mine action standards provide only a fairly narrow description of the issue. This implies that the field is missing opportunities to achieve efficiency and effectiveness, as well as to learn from and improve upon past experiences. The authors demonstrate herein that sampling provides little additional confidence as to whether a particular area is free from explosive hazards and substantial savings can be made compared to the current practice.
