Understanding design process robustness
A modelling approach
Mitigating the influence of uncertainty in design projects without sacrificing performance is challenging, but also important as it may reduce the risk of engineering projects delivering over time or budget. In this paper, we discuss process modelling and simulation as a route to

Redesigning the design process through interactive simulation
A case study of life-cycle engineering in jet engine conceptual design
Many aerospace companies are currently making the transition to providing fully-integrated product-service offerings in which their products are designed from the outset with life-cycle considerations in mind. Based on a case study at Rolls-Royce, Civil Aerospace, this paper demo

The P3 platform
An approach and software system for developing diagrammatic model-based methods in design research
Many issues in design and design management have been explored by building models which capture the relationships between different aspects of the problem at hand. These models require computer support to construct and analyse. However, appropriate modelling tools can be time-con

Integrated product and process models
Towards an integrated framework and review
While product models and process models have a long standing transiting, there are few models that integrate the two type of models. Those that exist are research systems, which even if validated in industry do not have a broad uptake to date. This paper develops an integrated fr

Simulating intertwined design processes that have similar structures
A case study of a small company that creates made-to-order fashion products
The authors use simulation to analyse the resource-driven dependencies between concurrent processes used to create customised products in a company. Such processes are uncertain and unique according to the design changes required. However, they have similar structures. For simula

This paper discusses a case study in which process simulation was applied to support the integration of life-cycle engineering activities into the existing design process at a major UK manufacturer of capital equipment. we demonstrate the practical value of process simulation as

Lean product development in practice
Insights from 4 companies
This paper aims to elucidate practitioners' understanding and implementation of Lean in Product Development (LPD). We report on a workshop held in the UK during 2012. Managers and engineers from four organizations discussed their understanding of LPD and their ideas and practice

Information models used to manage engineering change
A review of the literature 2005-2010
Engineering change is a significant part of any product development programme. Changes can arise at many points throughout the product life-cycle, resulting in rework which can ripple through different stages of the design process. Managing change processes is thus a critical asp

Improving data quality in DSM modelling
A structural comparison approach
The Dependency Structure Matrix (DSM) has proved to be a useful tool for system structure elicitation and analysis. However, as with any modelling approach, the insights gained from analysis are limited by the quality and correctness of input information. This paper explores how

Change impact on a product and its redesign process
A tool for knowledge capture and reuse
Change propagates, potentially affecting many aspects of a design and requiring much rework to implement. This article introduces a cross-domain approach to decompose a design and identify possible change propagation linkages, complemented by an interactive tool that generates dy

Communication and design process planning
Initial insights from literature and industry interviews
There is a complementary and bi-directional relationship between communication among design process participants and the planning activity in design. However, while often implied, this relationship is rarely discussed directly in the literature. This paper reports on the first ye

Design customisation in multi-project environments
Using process simulation to explore the issues
Adapting a design to the needs of a specific customer can be seen as a process in which an existing product is changed to incorporate desired properties and to exclude undesired ones. In a multi-project environment, many such projects are typically in execution at any given time

The evolution of information while building cross-domain models of a design
A video experiment
Models capturing the connectivity between different domains of a design, e.g. between components and functions, can provide a tool for tracing and analysing aspects of that design. In this paper, video experiments are used to explore the role of cross-domain modelling in building

Re-conceptualising value in the engineering design process
The value cycle map
Introducing a "Cheaper, Faster, Better" product in today's highly competitive market is a challenging target. Therefore, for organizations to improve their performance in this area, they need to adopt methods such as process modelling, risk mitigation and lean principles. Recentl

A modeling framework to support design process improvement
Companies which develop complex products are under constant pressure to produce better designs and to do so in less time, with lower cost and in more rational fashion than before. Achieving these goals often requires more than technical advancement; the processes by which product

A product's architecture can affect many aspects of product and process quality, from technical performance to the design effort required, production costs and satisfaction of later lifecycle requirements. This paper explores how computational tools can augment creative methods i

Graph structures are fundamental in many aspects of design. This paper discusses a way to improve access to design spaces of graph structures, by converting graph structures into numerical values and vice versa. Mathematical properties of such conversions are described, and those

A simulation model to help manage change propagation through design workflows is introduced. The model predicts resource requirements and schedule risk of a change process, accounting for concurrency, multiple sources of change, and iterations during redesign. Visualizations prov

Task-network modelling approaches are widely used to understand and improve product development (PD) processes. The best-practice application of these tools is often presented prescriptively. This paper proposes that best-practice, and academic understanding, of PD process modell

This paper examines design iteration and its modelling in the simulation of New Product Development (NPD) processes. A framework comprising six perspectives of iteration is proposed and it is argued that the importance of each perspective depends upon domain-specific factors. Key
