The scientific and industrial communities have begun investigating the possibility of making product recovery economically viable. Disassembly sequence planning may be used to make end-of-life product take-back processes more cost effective. Much of the research involving disassembly sequence planning relies on mathematical optimization models. These models often require input data that is unavailable or can only be approximated with high uncertainty. In addition, there are few mathematical models that include consideration of the potential of product damage during disassembly operations. The emergence of Immersive Computing Technologies (ICT) enables designers to evaluate products without the need for physical prototypes. Utilizing unique 3D user interfaces, designers can investigate a multitude of potential disassembly operations without resorting to disassembly of actual products. The information obtained through immersive simulation can be used to determine the optimum disassembly sequence. The aim of this work is to apply a decision analytical approach in combination with immersive computing technology to optimize the disassembly sequence while considering trade-offs between two conflicting attributes: disassembly cost and damage estimation during disassembly operations. A wooden Burr puzzle is used as an example product test case. Immersive human computer interaction is used to determine input values for key variables in the mathematical model. The results demonstrate that the use of dynamic programming algorithms coupled with virtual disassembly simulation is an effective method for evaluating multiple attributes in disassembly sequence planning. This paper presents a decision analytical approach, combined with immersive computing techniques, to optimize the disassembly sequence. Future work will concentrate on creating better methods of estimating damage in virtual disassembly environments and using the immersive technology to further explore the feasible design space.

“…The potential of VR in design was demonstrated by COVIRDS (COnceptual VIRtual Design System) which showed the interactive capabilities of immersive virtual design (Dani and Gadh 1997). Research has also investigated the use of data in log files to automate the generation of assembly plans and elicit simple knowledge (Ritchie et al 1999). This latter work has been carried forward very successfully into a design domain, detailing user activities (Ng et al 2000;Ritchie et al 2007).…”

One of the biggest challenges in engineering design and manufacturing environments is the effective capture of and decoding of tacit knowledge. Fundamental to Life Cycle Engineering is the capture of engineering information and knowledge created at all stages of the product development process, from conceptual design through to product support and disposal. Consider thisthe amount of vital information and knowledge lost when key design personnel retire-hence the need to capture meta-cognitive task-related strategies, particularly to support knowledge reuse and training. Many methods have been tried and tested with the successful few found to be very time consuming and expensive to implement and carry out; consequently, there is a need to investigate alternative paradigms for knowledge and information capture. This paper reports on a current industrial case study on knowledge capture methods employed by industrial partners in the design and manufacture of a variety of electro-mechanical products. The results suggest the need for new kinds and forms of knowledge capture methods and representation, particularly those associated with individual design engineering tasks. Following the findings, the paper presents a knowledge capture methodology for automatic real-time logging, capture and post-processing of design data from a virtual reality design system. Task-based design experiments were carried out with industrial partners to demonstrate the effective, unobtrusive and automatic capture and representation of various forms of design knowledge and information. Qualitative and quantitative evaluation of knowledge representations were also performed to determine which method was most effective at conveying design knowledge and information for other engineers.

This has been carried forwards into a design domain, detailing user activities [10] [11].…”

Drexel University, Philidelphia, USA AbstractWithin the context of Life Cycle Engineering it is important that structured engineering information and knowledge are captured at all phases of the product life cycle for future reference. This is especially the case for long life cycle projects which see a large number of engineering decisions made at the early to mid-stages of a product's life cycle that are needed to inform engineering decisions later on in the process. A key aspect of technology management will be the capturing of knowledge throughout the product life cycle. Numerous attempts have been made to apply knowledge capture techniques to formalise engineering decision rationale and processes; however, these tend to be associated with substantial overheads on the engineer and the company through cognitive process interruptions and additional costs/time. Indeed, when life cycle deadlines come closer these capturing techniques are abandoned due the need to produce a final solution. This paper describes work carried out for non-intrusively capturing and formalising product life cycle knowledge by demonstrating the automated capture of engineering processes/rationale using user logging via an immersive virtual reality system for cable harness design and assembly planning. Associated post-experimental analyses are described which demonstrate the formalisation of structured design processes and decision representations in the form of IDEF diagrams and structured engineering change information. Potential future research directions involving more thorough logging of users are also outlined.
