Virtuell montering i tidiga faser av produktutveckling / Virtual assembly in the early stages of the product development process

Bergman, Johnny, Sundbye, Erik January 2020 (has links)
This study has been a co-production between Mälardalen university and a company to see how a project can work with Virtual Reality (VR). The purpose of the report is to help develop a method proposal for virtual assembly in VR in the early stages of the product development process at the company and to help other companies in similar situations. The aim was how the new technology shall be incorporated into a process for the company through an effective and systematic approach. To get there, it needs to develop a work method in the processes for when, how and why the technology should be used and who should use it.Therefore, three research questions (RQ:s) were formulated; RQ1: How does the process look like today regarding virtual assembly in VR at the early stages of product development? RQ2: What prerequisites must exist to be able to implement Virtual assembly at the early stages of product development? RQ3: What can be tested using virtual assembly in VR at the early stages of product development? To answer these questions, observations, interviews and a literature study from relevant articles on the subject were used. These articles were found by searching in various scientific databases with different search terms. The interviews were used to gain insight into how the company is working with VR now and what prerequisites would be needed to implement VR into the projects. In this study, direct observations in meetings, tutoring and conversations were used both in physical and virtual environments to get a deeper understanding of the company's problem. The report resulted in these conclusions:The company did not have a work method for virtual assembly with VR at the early stages. However, there were no description for virtual assembly with VR in any part of the company's product development process. If there is no work method about virtual assembly with VR in the company's product development process can these identified preconditions support; understanding the gain with VR, educated workers, the workers having an interest, having room for VR with hardware and software. These preconditions can facilitate the work, which could reduce time and save money for the project. This investigation show that a project can test seven VR variables. These variables are assembly, assembly complications, accessibility, risks, quality, visualisation and does it fit in the factory. All these variables show that VR has great protentional but how much VR can test depends on the company’s prerequisites. Finally, based on the findings in this study and in order to facilitate work with virtual assembly in VR in the early stages of product development, the report presents a prototype checklist with three steps. The data gathered in the study only comes from one company, so the proposal for further research include validation of the checklist in several industries.

The Unbundling and Rebundling of the Faculty Role in E-Learning Community College Courses

Smith, Vernon Clay January 2008 (has links)
The unbundling of the faculty role occurs when e-learning course tasks normally performed by a single faculty member--such as course design, development, delivery, grading, interaction with students, course improvement, and advisement--are segmented or unbundled so that they can be performed by other personnel or with technologies. Using a qualitative methods approach, this study examines the unbundling and restructuring of the faculty professional role in large enrollment e-learning courses. This study was conducted at three community colleges in a large, urban community college district, and presents three models of e-learning course production that affect the unbundling of the faculty role: craft, collegial, and virtual assembly line. This research also examines how e-learning faculty members seek to rebundle tasks associated with their professional role and identity, and the tasks they perceive as meeting student needs and demand. This study contributes to professional and economic theories concerning faculty members in the e-learning context, and advances theories associated with academic labor, managed professionals, Academic Capitalism, and the globalization of the community college.
