- The benefits of having users evaluate product or workplace design during the development process are well known. This is often achieved by letting users interact with one or more models of the design proposal, in order to elicit feedback. The issue for product developers is to choose what type(s) of models to use (from paper drawings to physical or virtual mock-ups or fully working prototypes) and when to use them in the development process, while making optimal use of resources like time, money and personnel.This paper compares three types of simple three-dimensional (3D) models (1:1 scale, 1:16 scale and CAD) representing a ship bridge workstation, examining what kind of feedback they elicit in a design evaluation with representative users. Participants were asked to assess the proposed design and to compare the models' relative merits. The study found that while all three types of 3D models elicited several types of useful design feedback, there were differences in both quantity and content of the feedback elicited by each model type. The physical models elicited more feedback than the CAD model, both regarding content richness (direct and indirect design feedback) and quantity. The tangibility of the models seems to greatly influence acceptance and credibility.

Konferensbidrag (refereegranskat)abstract
- The benefits of involving users in a development process are well described. This paper describes a procedure for using 2D and 3D models in a workplace design process, which is based on three rounds of user studies within the maritime domain. The process includes various kinds of models that can be used in order to elicit design feedback in a cost-effective manner. Design teams can greatly benefit from using such mediating objects to draw out the users’ previous experiences. It was found that different model types allow different levels of reflection and questioning of the design from the prospective users.

Manual picking from flat and tilted pallet containers
- 2018

Ingår i: International Journal of Industrial Ergonomics. - : Elsevier BV. - 1872-8219 .- 0169-8141. ; 64, s. 199-212

Tidskriftsartikel (refereegranskat)abstract
- Manual picking operations commonly occur both in distribution settings and within manufacturing industry and may consume large proportions of the working day for operators, with associated potential problems of poor postural ergonomics and low time efficiency. As a remedy to such problems, alternative material layouts like tilted material pallets may be an attractive solution. This study provides quantitative empirical evidence comparing the relative merits and drawbacks of flat and tilted pallet configurations, with regard to physical ergonomic loading and time consumption. This was explored with an experimental setup at the site of an industrial company, where various representative picking operators were observed while emptying flat and tilted pallets. The observation was video recorded and subjected to a time study and Rapid Entire Body Assessment (REBA). Results showed that there are differences in picking time and physical workload depending on where in the pallet the picking action takes place, and that flat and tilted pallets bring different postural opportunities and challenges for different operator percentiles in the working population. An overview of postural ergonomics consequences and their associated risk levels are shown, and the results serve to further increase the understanding of which factors are affected by choosing between a tilted or flat component presentation. This understanding is highly relevant to industry, where it can contribute to the design of both efficient and ergonomically sound processes for manual picking operations.

- The globalized nature of the shipping industry poses challenges to a traditional set-up of a collaborativedesign and development team involving end-users. The present study explores aspects of end-user involvement and three different 3D models’ abilities to act as boundary objects in a ship design process.The preliminary results indicate that the evaluation methods and representations used in the study produced valuable design feedback. With relatively small means, the procedure supports the benefits of employee participation, contributing to a safe and efficient ship design and subsequent operation.

- The context for this study is the maritime domain and the design of shipboard workspaces. Due to the globalized nature of shipping, the traditional approach to a participative ergonomics process can be a logistical challenge since stakeholders like designers, manufacturers and operators are often scattered both geographically and organizationally.The participative design study presented in this paper addresses this challenge by exploring the ability of three types of simple three-dimensional (3D) models to act as mediating objects for representative users in order to elicit design feedback in a use scenario workshop format. The study found that all three types of 3D models, when coupled with a scenario description, elicited several types of useful design feedback that served not only as direct input to changing proposed design parameters, but also as an unprompted long-term learning opportunity for the design team to gain insight into the lives and challenges of their users, who both work and live on board.Relevance to industry: The paper presents a procedure for a participatory design process in the maritime domain where the involved stakeholders are geographically and organizationally dispersed. Mock-up models coupled with use scenario descriptions elicited useful design feedback and an unprompted long-term learning opportunity for the design team.

- Virtual Reality (VR) holds promise as a potential professional work tool – one such potential is to support office work tasks. VR is a simulated environment accessed via head-mounted displays and hand-controlled devices for interacting with the virtual interface. This paper aims to provide a state-of-the-art review of empirical research on VR-based office work, focusing on ergonomics. A structured literature database search and criteria-based exclusion led to a total of 5 papers addressing office work in a VR environment. The research on VR-based office work identifies potentials and drawbacks relevant to consider for future research and developments. The identified studies examine technical solutions, task performance, user experience and comfort when using VR-based solutions. The fast pace of technology development, e.g lighter headsets, increased field of vision and screen resolution, new controls, and the emerging plethora of new software may resolve many identified challenges, while perhaps introducing new problems.

Konferensbidrag (refereegranskat)abstract
- How do core business and manufacturing capabilities enable strategies for sustainable manufacturing, and what are those capabilities? This paper proposes a Capability Methodology for Sustainable Manufacturing (CMSM) for allowing top management of manufacturing companies to address these questions. A diagnostic tool was developed from three case studies based on a set of interview questions aimed at identifying core capabilities and sustainability issues in manufacturing companies. Interview data was coded and mapped through a relational matrix formulation that describes four archetypes for the development of sustainability strategies. The matrix maps the degree of complexity of the sustainability concept as understood by the company, and the scope of the product life cycle being considered. It is argued that the methodology helps bring awareness to managers of any gaps or mismatches between their actual core capabilities and the desired outcomes for sustainable manufacturing.

Konferensbidrag (refereegranskat)abstract
- Currently few attempts to properly structure knowledge that specifically supports a fully sustainable e-waste treatment system design have been proposed in literature. As a result, this paper sets up the prerequisites for a high-level framework to design sustainable plants in the supply chain of e-waste. The framework addresses production and environmental engineers mainly. The methodology grows out of literature studies, research project’s outcomes and interviews with a group of sector experts. Stemming from this, a list of prerequisites was presented for the case study of an automated plant for e-waste sorting in order to design it while considering the triple-bottom-line of sustainability.
