The Design
Decisions Laboratory develops tools and methods to
understand and assist decision-making in the design process. Current thrust
areas include
1.
systems optimization,
2.
design for market systems, and
3.
green design &
environmental policy.
A
current application focus is life cycle implications of advanced vehicles,
including plug-in vehicles.
Systems Optimization
|
|
The design and optimization of
complex systems pose unique challenges: Subsystems and components must be
designed such that they are compatible and consistent with one another
while delivering properties that, in combination, achieve targets for the
overall system. DDL develops mathematical tools for decomposing complex
design tasks into smaller subsystem design tasks and coordinating design
of these subsystems to achieve optimal system solutions.

Design for Market Systems
|
|
Whether interested in profit or
in social welfare, designers are concerned with the preferences people
have and the choices they make. Design decisions are driven by the
preferences of various stakeholders, and the decisions made by designers
have impact on these stakeholders. DDL develops quantitative tools to
model and predict consumer behavior and competitive firm behavior to
guide product design decisions to perform well in the marketplace.

Green Design and Environmental Policy
|
|
Environmental regulations attempt
to correct for market failures by altering incentive structures or
restricting the space of options available to designers. Such regulations
have direct impact on the decisions made by designers, and the success of
any such policy depends upon the product designs that result under
regulated market conditions. DDL builds models to understand and predict
the effects of policy on the incentives that drive design decisions and
the resulting impact on producers, users, society and the
environment.

Information Systems for
Sustainability
|
|
The lack of simple, reliable,
convenient, and accessible information about the social and environmental
impact of products and their producers results
in consumers ignoring such attributes, leading to undervaluation in the
marketplace and providing economic incentive for corporations to
compromise social and environmental responsibility in pursuit of reduced
cost and increased market share. DDL aims to provide consumers with quick
and simple access to customizable information about the social and
environmental characteristics of products and their producers on demand
and at the point of purchase.

Architectural Design
|
|
Most Computer Aided Design (CAD)
tools offer precision, but when a designer needs to quickly explore
concept options and think through design alternatives they typically
sketch with pencil and paper. DDL has used optimization in the early
conceptual stage of design to help the designer to quickly generate and
compare alternatives visually and computationally while interactively
refining design goals and constraints and visually guiding
search. This allows the designer to integrate subjective judgment
and experience with the computational power of optimization algorithms to
achieve maximum efficiency while considering aesthetic and usability
issues that are difficult to quantify.
