- In a time of change focusing on the application of technology, there is a high risk of underestimating the compliance of internal needs and adaption to context. The research study employs a qualitative approach using the case study methodology. The source of data comes from five different manufacturing companies categorized as Small to Medium Size Enterprises (SMEs). A multidisciplinary team performed semi-structured interviews and fieldwork at each site, along with regular online meetings with the partners. The study employs five dimensions of the information quality perspective to assess information utilized to support deviation handling and connects the information quality deficiencies to the digital tools' impact. The empirical findings indicate the need for the companies to perform a requirement analysis of information needs before the adoption of digital systems or digital tools, to assess their current state in terms of data and information. The paper discusses the impact digital tools may have on deviation management in SMEs and under which circumstances digital tools could improve deviation management. Lastly, this paper intends to shed light on the utilization of digital technologies for disturbance handling on the production shop floor. © 2020 The authors

Inter-Relation Between Product Variant Codification and Assembly Work for Flexible Manufacturing in Autonomous Group

Tidskriftsartikel (refereegranskat)abstract
- The most socio-technically advanced assembly system designs inventible requires reformed/reconfigured information systems dealing with product data (which in turn defines the product architecture and product variation). In fact, no any such (real-life) plant or assembly system would work as anticipated otherwise. And this publication is to some extent describing some selected aspects of this (very) dilemma (changing information systems are usually not something considered than designing assembly systems) (thus are totally new plants – and in turn totally new information systems – most often the real practical change to create something unorthodox) (however, which scientist will gain such opportunities, this is really rare, i.e. the projection of the Volvo Uddevalla plant was thus an exception and the trust given by the industry – by Volvo Uddevalla project organisation – was appreciated by some of the authors).

- Purpose – The purpose of this paper is to determine how kitting, compared to continuous supply, affects the time spent by the assembler fetching parts in manual assembly. Design/methodology/approach – The paper is based on an experimental setup at the Saab Automobile assembly plant in Trollhättan, Sweden. Experienced assemblers were studied as they performed the same assembly operations in ten different configurations. Each configuration consisted of a different arrangement in terms of how parts were presented. The use of kits to present parts was compared to parts presentation through continuous supply, where each part number was presented in a separate container. Findings – The time for fetching parts is significantly shorter when parts are presented through kitting instead of through continuous supply. Furthermore, the shorter fetching time is not just related to a shorter distance between assembly object and parts presentation, which can often be achieved through kitting. The reduction of time spent searching for parts is also considerable. Practical implications – The results of the paper provide valuable input in the design of assembly and materials supply systems, as they enable a better understanding of the relative performance of the materials feeding principles of kitting and continuous supply. Originality/value – Previous studies of kitting and its impact on assembly are mostly conceptual or qualitative, whereas quantitative studies are scarce. The current paper provides a substantial contribution by quantifying the effects that kitting, compared to continuous supply, has on the time spent fetching parts.

Avenues of entry: how industrial engineers and ergonomists access and influence human factors and ergonomics issues
- 2014

- This study compares how Canadian industrial engineers (IEs) and ergonomists ‘position themselves’ to influence human factors and ergonomics (HFE) issues. The study examined how these stakeholders perceived their influence on HFE issues, constraints they operated under, and strategies used. The results contribute to an understanding of decisions and processes surrounding HFE practices, showing that organisational entry points and stakeholder expectations on IEs and ergonomists affect their influence on HFE issues. Ergonomists influenced HFE issues by leveraging their knowledge of other stakeholders’ priorities, and were more dependent on accessing the issue via a ‘problem owner’. IEs were often entrusted with greater freedom to act on improvements. Expressing HFE improvements in terms of business benefits was a successful strategy for both. It was found that ergonomists operated as ‘partial solution builders’, trying to influence the HFE issue as an expert, lobbyist or facilitator. Based on the results, an existing framework was modified.

- This publication initially reports on data collection and analysis of assembly systems including manual work using the so-called `loss analysis' which we have applied to the automotive industry during two decades of research and development work. In the further development of this method of analysis we have during the last few years synchronized a personal computer and a video recorder, thereby facilitating data collection of true shop floor information, as well as developing the analysis procedure to also include ergonomic aspects and work performance in the analysis. This publication reports on: (1) the background, (2) the prototype equipment used for data collection and analysis which is illustrated by empirical data using the equipment to analyze stamping of sheet metal, as well as assembly of automobile doors and drivelines, and (3) how to integrate a `loss analysis' with an ergonomic analysis of working postures (in this specific case using the so-called OWAS technique) studying assembly work on an automobile door. In this case, we noted that the division of labour loss represents over 60% of the time consumption for assembly work. This analysis indicates that from an ergonomic point of view it is primarily worth studying what activities are included in the assembly work classified as OWAS workload level 2. Relevance to industry This paper describes and illustrates methods and equipment developed consisting of a synchronized personal computer and video recorder. This promotes a design based on empirical data for specific cases through facilitating the collection and analysis of shop floor information about manual work and process efficiency of interest for the design of assembly systems.
