Introduction
The development of competitive products demands knowledge about market demands,
products and production processes. Product development is complex and existing
products hold a variety of qualities that must be known to the designer and the company
to attain success. The qualities that the product holds are linked to the product
(consumer perceived Quality - big Q) and the production (the production perceived
quality - small q). A thorough understanding of the product and the interdependent
production processes will provide the basis for a successful business.
By use of an organised information structure grounded in the product and the production
characteristics, respectively, it will be possible to get insight where and when
competitiveness is located. In the following we will describe the product and process
topological structures - "the chromosomes" as an introduction to a sustainable business
concept.
TALAT 2110.02 2

3. The Product Topological Structure
During the process of product design, the "anatomy" of the product as a technical system
is established. All the information about the product can be organised and connected in
four levels, the theory of domains [Andreasen]. The levels are similar to the "generic
code" of a biological system, and is termed a product "chromosome".
The domains embrace the total product process (the transformation), the supporting
functions, organs and contributing components, as illustrated in Figure 2110.02.01.

Topological Structure of a Product 2110.02.01
The total product process or transformation that the products perform is what the
product is made for (e.g. moving goods or people from A to B). The total product
process domain holds other sub-transformations (e.g. give controllable reduction of
speed of an automobile) contributing to the total product process. Each of these sub-
transformations is prescribed and solved by organising and connecting subsystems in
space [Tjalve]. Each of the subsystems performs specific functions. They are expressed
by a substantive and a verb (e.g. transfer braking power or allowing motion). The
functions describe the functional properties of the product.
One or several organs (interactions between surfaces) realise the described functions.
The organs will provide information about the interplay between the component's
contribution to the realisation of the functions. Each organ may have different
characteristics determining the functional properties of a subsystem. An organ may be
described by its ability to create friction (e.g. the interplay between a brake rotor pad and
the brake rotor). The last domain is the component level consisting of an organised and
interrelated system of components in an assembled structure.

4. A complete product information organised in the chromosome, will provide necessary
insight and expose key competitive parameters within each domain contributing to the
total product process and indirectly the consumers' perception of the product.
The Process Topological Structure
Simultaneously to the creation of the product the related production characteristics are
determined. The production system is determined at different levels/domains similar to
those of the product structure. The structure of the information system, "the process
chromosome", provides the total information of the processes that are needed to create
the product. The process chromosome is illustrated in Figure 2110.02.02.

Topological Structure of a Process 2110.02.02
During the process of product design, the processes in the production system are
established. The production system describes the production network and system that
produce the product in production. The product organisation holds different process
lines that produce the different subsystems to the specified system (e.g. wheel system
production). The different processes that contribute to the process line are described as
process units. The brake rotor needs to be cleaned and machined before it is assembled
to the wheel system. The process units' activities prescribe the characteristics to the
organs (e.g. cleaning and machining of casted components). The lowest level of the
production system is the assembly of the interrelated system of components. The
assemblies contribute to the process units.
TALAT 2110.02 4

5. A complete process information organised in a chromosome hierarchical structure will
provide needed insight and expose key production parameters contributing to the
performance of the product.
Know Your Product
The product has an operational life time and the quality of the product is the user's
perception of the product, related to how well the product performs its "transformation".
It may be in absolute terms, related to the users' expectations or his comparison with the
competitors' products. The users of the product can be customers or company internal
"employees" that meet the product respectively under its use or its production. QFD
(Quality Functions Deployment) is a systematic method to investigate the customer's
perception of the product. Data about the market, customers and competitors are
collected and organized to get a true insight where and when the competitiveness in the
product is located. The QFD procedures and matrixes correspond to the domains. A
similar approach to systematize the productions' critical parameters as an underlying
basis is the use of qfd (quality function deployment) collecting and organizing the
small-q information. The small quality function deployment is the similar procedural
approach as the more known big-Q tool revealing the productions' perceived quality. It
includes collecting and organizing data from industry, suppliers and competitors to
reveal the critical production parameters for the product in production
By the concept "Know Your Product", as illustrated in Figure 2110.02.03, we
understand a systematic analysis of a product in production, based on the chromosomes,
with the purpose to identify where the competitiveness of the product is located. In this
way the innovative effort can be directed toward what is of real value for the society and
the individual user.

The Life Cycle Logistics
In the design and product development process, from idea to production planning, the
designer has to make decisions about the shape, dimensions, surface and production of
each component, including material selection and the processing route. The components
and the subsystems have a "life" before they are a part of the product. Also, after the
functional life of the product, the individual subsystems may be discarded, reused or
reprocessed. So each component has a "life" after the "death" of the product itself. By
letting the "product chromosome" follow the product during its operational life, the
history of the product can be monitored in a systematic way; the operational practice, the
mechanical, the chemical and thermal loads, accidents etc. Likewise, any changes of the
components, organs and functions, due to wear, plastic deformation, cracks, changes in
material properties can be followed through the life of the product, as well as
replacement and repair of components or subsystems. The "process chromosome"
operates before and after use, respectively in production and after use when the product
is reprocessed.
With the concept "Life Cycle Logistics" we understand the information about the
geographical transfer and all the information related to the components at the different
stages of its life from "cradle" to "grave". This is illustrated on the Figure 2110.02.04
above the "chromosome".

Life Cycle Logistics 2110.02.04
Knowledge of the life cycle of the components and the product serves as a basis together
with the QFD and qfd procedures for design of products, considering the life of the
product and the interdependent environmental impacts.
The Universal "Virtues" of the Product or a Technical System
Seen from a global perspective, where one estimates that the population will increase to
about 12 billion in the next 100 years, and we want that every one of these persons
should live a worthy life, we have to have a measure of each product to test if the one is
more sustainable than the other. With "sustainable" is understood that the product, the
materials and processes used, the production, functional and recycling practice, as well
as the life style related to the product, can be used or practised forever in order to
improve the quality of human life within the carrying capacity of the supporting
ecosystem. The "universal virtues" are measures that can be used for a product, a
subsystem or a component, in order to assess the degree of sustainability of a product or
a component compared to another. It is obvious that we do not have a unique way to
make such a ranking of materials, processes, product and practices. But everybody
should think about it and do as best as he/she can. Improved sustainability can be
"designed" into a product. We look here for measures which the designer can use to
"design for sustainability".
TALAT 2110.02 7

These measures have to consider time steps in the life of the component and the product,
including the source of raw material and all the equipment and chemicals used to
process, use and recycle the product. There is a great need for structure and quantified
information as well as theories and methods for such evaluations.
The Life of a Component - Interaction between Function, Shape,
Processing Route, Microstructure and Properties
In the search for improvements of critical properties of a component, it may be useful to
organise the information related to this particular component as shown on Figure
2110.02.06 [Støren].
The horizontal axis represents the life time of the component, the scale is not linear in
time, it represents the main stages in the life of the component.
The vertical axis represents a logarithmic scale. The distance between the two vertical
lines gives the dimension scale that the figures or the phenomena operate at that vertical
position. At the bottom of the scale, we have the atomic level, dimensional scale 1nm

top of Figure 2110.02.06, we are at a global scale, reflecting on the global need and
sustainability of the component, the dimensional scale is 1 Mm.

This representation is particular suited for studying and modelling the relation between
alloy constituents, process parameters, microstructural evolution and the many
properties of the alloy-component-system. In computer databases, often 50 or more
properties of the material are given. These properties come from the same
microstructure, some are very sensitive to the microstructure, other properties are not.
By a representation given as above we can focus on the critical properties for the
given shape and dimensions and identify its source at microstructural level, and then
trace back to processing parameters or alloy constituents.
A Business Concept
By the "chromosomes", the "life cycle logistics", "the universal virtues" and the
"material/component hierarchical structure" a complete product, process and market
information are established. The combined use of the "Know Your Product" concept,
the life cycle logistics and the material/component hierarchical structure constitute a
business concept, that is well suited to expose the competitiveness of the product in
production and the company's business as a whole. The concept is illustrated in Figure
2110.02.07.

Business Concept 2110.02.07
Knowledge about critical technical, economic and ecological parameters will provide a
foundation for the creation of a business concept using daily business performance
indicators as input to develop market, product and production strategies. The output
of the analysis will be knowledge about these key competitive parameters and future
areas of emphasis in the design process.
The business concept structure demands well-organised data within all categories, a
common understanding of sustainability, accessible technological, ecological and
economical data besides a commitment from individuals involved. A common
knowledge and information database will provide input to the different assessment tools
providing data to the business concept. These assessment tools are:
− A Personal Environmental Accounting system that analyses each individual's
consumption of products and services. The consumption of product and services
are a major source for improvements besides the importance of environmental
consciousness among designers and users of products.
− The Industrial Ecology assesses the interactions between the industrial man-
made system and the natural system evaluating flows of materials and energy
between them.
− The Product Life Cycle Assessment includes analysis of the environmental
impacts the product and belonging processes dictates in addition to improvement's
analysis.
TALAT 2110.02 10

11. − The Product and Process technology assessment evaluate, respectively, the
product and process technology that is necessary to satisfy the economic and
ecological demands.

Business Concept (2) 2110.02.08
The business concept structure is well suited for computer software programming and
visualisation. Within this environment, "design for sustainability" should be carried out.
In the Nordic countries the first step is taken in this direction by the development of the
software ALULIB/ALUBOOK based on the "chromosome" concept. (SkanAluminium
project "Design with aluminium")
Life Cycle Assessment
The life cycle assessment is an objective process to evaluate the environmental burdens
associated with a product, process or activity by identifying and quantifying energy and
materials used and wastes released to the environment, to assess the impact of those
energy and material uses and releases to the environment, and to evaluate and
implement opportunities to affect environmental improvements. The assessment
includes the entire life cycle of the product, process or activity, encompassing extracting
TALAT 2110.02 11

12. and processing of raw materials, manufacturing, transportation and distribution, use, re-
use, maintenance, recycling and final disposal. LCA is:
A scientific analysis and evaluation of potential environmental and health
impacts of a product system, throughout its entire life cycle.

Life Cycle Assessment - General Principles 2110.02.09
The LCA includes three steps which are inventory, impact and improvement
assessment, see Figure 2110.02.09.
Life Cycle Inventory is an objective, data-based process of quantifying energy and raw
materials requirement, air emissions, waterborne effluents, solid waste and other
environmental releases incurred throughout the life cycle of a product, process or
activity.
Life Cycle Impact Assessment is a technical, quantitative and/or qualitative process to
characterise and assess the effects of the environmental loadings identified in the
inventory component. The assessment should address both ecological and human health
considerations, as well as other effects such as habitat modification and noise pollution.
Life Cycle Improvement Analysis is a systematic evaluation of the needs and
opportunities to reduce the environmental burden associated with energy and raw
materials use and waste emissions throughout the whole life cycle of a product, process
or activity. This analysis may include both quantitative and qualitative measures of
improvement, such as changes in product design, raw materials use, industrial
processing, consumer use and waste management.
Product development or product design consists of different phases, which can be
structured in a variety of ways. Market, process and product analysis serve as input to
the development activities: concept, form design and detailing. In each phase different
decisions are taken regarding the product and the production, selecting the best
TALAT 2110.02 12

13. solutions. The best solution can only be determined when the designer has access to
necessary data and when he/she is able to use the data as basis for trade-off's, sensitivity
and error analysis. The found key competitive parameters should be focused and
handled along with all acting parameters. A successful product assessment involves
quantitative and qualitative aspects considering ecological, technical and economic
problems in all development phases. Life Cycle Assessment serves as a basic tool to
analyse the product in production or as support to environmental sound decisions in
product development.
