Konferensbidrag (refereegranskat)abstract
- Assembly systems are complex due to mass customization. In order to be able to produce a variance of products a well functional information system is vital. Companies need a digital strategy in order to design adaptive systems to increase flexibility and usage of information support systems (IS-Systems) among operators. In case studies from Swedish industries, it is shown that operators often use their own experience when assembling products. This paper aims to describe how a digital strategy can be developed, combining IT-systems and IS-system to create dynamic systems for operators. The paper will combine two methods, MEET-model that has been used to improve meeting situations but could also be used to create digital strategies at companies. An additional use of the Delone and McLean model will be used to create the bridge between the IT-system and the IS-system. Results show that combining these models gives a clearer and broader view of the digital strategy and a possible bridge between IT-and IS-developers to create a better and more dynamic shop-floor IT system.

- Information is a vital resource in development activities of any business. These systems also play a very important role in the knowledge sharing of an organisation. In order to properly bridge over from the information system to the organisation system, the transformation process from data, via information, to knowledge becomes important to understand. A challenge is to create appropriate conditions in both the organization system and in the information system enhancing knowledge sharing among employees, and promote organizational learning. This paper will analyse an industrial example of weekly planning meetings for preventative maintenance, this will be illustrated in the OS-M-IS model i.e. were the information sharing exist in a current situation (whiteboards). A future situation of the same case will be tested and evaluated in a lab environment (with SMART boards and iObeya) as a first step.

Konferensbidrag (refereegranskat)abstract
- Collaborative robots becomes more and more common in lab environment and soon also in industry. In order to create resource- and volume flexibility, dynamic and smart automation could be seen as an answer. This paper has investigated the collaborative robots UR3 and UR5 for O-ring assembly and final assembly, compared to the current state which is performed manually. The methodology Dynamo++ was used for measurement and analysis in terms of LoA (cognitive and physical), cycle-time and quality. Furthermore, automation strategy, safety and easiness of programming was investigated. Results show that collaborative robots have great potential in the middle product volume area. A lot of time, layout space and money could be saved with these solutions. However, standards and safety has to be investigated further in order to reach its fully potential

Development of virtual reality support to factory layout planning
- 2019
-
Ingår i: International Journal on Interactive Design and Manufacturing. - : Springer Science and Business Media LLC. - 1955-2505 .- 1955-2513. ; 13:3, s. 935-945

Tidskriftsartikel (refereegranskat)abstract
- Virtual reality (VR) technology has become ever mature today with affordable and yet powerful hardware. In the manufacturing industry, there is a growing interest of adopting VR to improve existing work procedures. Factory layout planning (FLP) is a long standing area in production engineering that sees great potentials of VR integration. Virtual reality supported layout planning (VLP) is gaining wider attention in research and practice as the virtual environment allows designers to test out “what if” scenarios in relative ease. However, previous research of VLP mostly focus on general layout planning but not the detailed level planning. Also, it is reported that the virtual modeling process is time-consuming and costly. In this study, we propose a point cloud based virtual factory modelling approach for the VLP tasks. It incorporates point cloud representation of physical environment with CAD data to model the virtual factory with the aims of simplifying the modelling process and improving decision-making for the VLP tasks. The proposed approach is exemplified and refined through three industrial cases. The implementations and results of the cases are highlighted and discussed in details. At the end, a general guidance for VLP is extracted and presented for future point cloud based VR support in FLP tasks.

Testing Operator Support Tools for a Global Production Strategy
- 2016
-
Ingår i: Procedia CIRP. - : Elsevier BV. - 2212-8271. ; 44, s. 120-125
-
Konferensbidrag (refereegranskat)abstract
- Globalisation of industry puts new demands on technologies and instructions to work in different time-space contexts. This paper examines four different support tools that can be used for different time-space contexts: face-to-face instructor (same time-same place), remote guidance with augmented reality (same time-different place), movie-based instructions and text-picture based instructions (different time-same place). Experiments of simulated product assembly were conducted to measure assembly time, product quality and the operators’ subjective emotions of the support tools. In total, 46 number of tests were conducted. Results indicate that the different support tools have both advantages and disadvantages, and therefore selecting appropriate support tools is dependent of the situation.

Assessing Operator Wellbeing through Physiological Measurements in Real-Time - Towards Industrial Application
- 2017
-
Ingår i: Technologies. - : MDPI AG. - 2227-7080. ; 5:4, s. 61-
-
Tidskriftsartikel (refereegranskat)abstract
- This article focuses on how operator wellbeing can be assessed to ensure social sustainability and operator performance at assembly stations. Rapid technological advances provide possibilities for assessing wellbeing in real-time, and from an assembly system perspective, this could enable the assessment of physiological data in real-time. While technology is available, it has not been implemented or tested in industry. The aim of this paper was to investigate empirically how concurrent physiological measurement technologies can be integrated into an industrial application, in order to increase operator wellbeing and operator performance. A mixed method approach was used, which included a literature study, two laboratory tests, two case studies and a workshop. The results indicated that operator wellbeing could be assessed through electro-dermal activity, but that the data is perceived as difficult to interpret. For an industrial application, operator perception and data presentation are important and risks connected to personal integrity and IT-support need to be addressed. Future work includes testing how a combination of physiological measures and self-assessments can be used to assess operator wellbeing in an industrial context.

Assembly 4.0: Wheel Hub Nut Assembly Using a Cobot
- 2019
-
Ingår i: IFAC-PapersOnLine. - : Elsevier BV. - 2405-8963. ; 52:13, s. 1632-1637
-
Konferensbidrag (refereegranskat)abstract
- To achieve a flexible and adaptable assembly system (assembly 4.0) a combination of enabling resources and technologies are required. Collaborative robots (Cobots) are one such technology that can offer higher flexibility and quick adaptability in assembly systems. Cobots are becoming more common in the manufacturing industry, the use and application of cobots are constantly growing. Combining cobots with IIoT gives the possibilities to also communicate with cobots and employees to achieve an effective assembly system. This paper presents a design research experiment conducted using cobots in a lab environment. The experiment studies the use of cobots in a final assembly environment with the focus on testing feasibility, improving quality and ergonomics of a real industrial operation. The experiment setup is presented in detail and the results are discussed along with future research directions.

Konferensbidrag (refereegranskat)abstract
- In this initial research work, different approaches that allow to represent production processes that can be shared by humans and robots are analyzed. Focus is given to approaches that support modular process model structures, allowing to hide details of how tasks are implemented. This is necessary, as a single task might be realized by a human or robot, and both agents need the task description on a different level of granularity.

Information for operational tasks: five cases in Swedish production
- 2015
-
Ingår i: The International Conference on Flexible Automation and Intelligent Manufacturing (FAIM). - 9781910864005
-
Konferensbidrag (refereegranskat)abstract
- Better resource utilisation for production systems can be achieved in many different ways. When it comes tohuman workers, they can either be allocated as more flexible machines, loaded with materials and a set ofinstructions, or they can be trusted to plan their own work. Moving towards the more automated and highlyconnected future production system suggests that human operators should be more empowered. This requires thatthey can be provided with the tools and environment that allow for this. Human workers need information but it isnot clear how that information should be made available. This study presents five cases from four Swedishcompanies in the manufacturing industry. The tasks and decisions the operators do are presented in relation to theinformation that is available, the experience level needed and the communication of the eventual outcome.
