In many large engineering design organizations the information systems have developed over time into a set of heterogeneous resources. This makes it difficult for engineers to follow a trail through the resources. This situation becomes particular difficult when the Engineer is new to a company; unfamiliar with the systems and unaware of the history of the(More)
We present a novel algorithm for accurately detecting all contacts, including self-collisions, between deformable models. We precompute a chromatic decomposition of a mesh into non-adjacent primitives using graph coloring algorithms. The chromatic decomposition enables us to check for collisions between non-adjacent primitives using a linear-time culling(More)
Typically, complex engineering artifacts are designed by teams who may not all be located in the same building or even city. Additionally, besides having to design a part of an artifact to be consistent with the specification, it must also be consistent with the company’s design standards. The Designers’ Workbench supports designers by checking that their(More)
The Designers’ Workbench is a system, developed by the Advanced Knowledge Technologies (AKT) consortium to support designers in large organizations, such as Rolls Royce, by making sure that the design is consistent with the specification for the particular design as well as with the company’s design rule book(s). Currently, to capture the constraint(More)
This paper presents a future vision for the working practices of designers within a manufacturing organisation. By its very nature the engineering design environment is highly distributed in nature and is characterised by a large number of information sources, which together with the designers forms a complex sociotechnical system. In discussions with(More)

We present a tool which helps domain experts capture and maintain constraints. The tool displays parts of an ontology (as classes, sub-classes and properties) in the form of a tree. A number of keywords and operators from a constraint language are also listed. The tool helps a user to create a constraint expression. Additionally, the tool has a facility(More)
This paper examines the effectiveness of human factors initiatives and addresses some difficulties reported in calculating the value of such interventions. Company representatives and researchers applied a novel probabilistic assessment tool to estimate the financial impact of two macro-ergonomic projects. Key benefits of the company intranet project(More)
