EU lacks chains in its industrialization model. In a new multipolar world, the absence of autonomy may cause disruptions. The new model of reindustrialization should be sustainable. Sustainability has the well-known three vectors of environment, enterprises, and society. All changes will be possible with the willingness of people. It is through edu...

Sustainability and a circular economy (CE) are crucial for the development of society. The CE approach should start by designing new products or processes or retrofitting existing ones to achieve the best efficiency and extend their life cycle. Designs that enable CE require the guidance of a design theory. Axiomatic design (AD) theory allows for t...

Energy Sustainability has been addressed through advancing technology efficiency, which may increase the impact of the use of natural resources. However, the increase in efficiency makes services cheaper, which causes a rebound effect, direct or indirect, on energy consumption and materials. Moreover, the popular concept of recycling seems insuffic...

Suh introduced two design axioms to the engineering community about four decades ago. Compared with other theories which presuppose an algorithmic or an iterative approach specific to a field of engineering, Axiomatic Design (AD) can be applied to solve a wide variety of problems.

Picking the best design solution among a small collection of viable alternatives is often a part of engineering design. The traditional method to do it is the weighted multicriteria decision procedure. However, the Axiomatic Design (AD) framework does not employ weighting factors to deal with design preferences. Instead, AD uses the careful placing...

A unified view of the Information System (IS) design is essential for dealing with complexity. However, the literature proposes many denominations, depending on the layer, methodology, framework, or tool. This multitude of approaches does not allow a holistic view of the system. Besides, in Information Systems, the search for good practices in desi...

The preceding chapters presented the basic concept of Axiomatic Design (AD). This chapter takes “MAPPING,” one of the important concepts of AD, to deeper understanding. Mapping between the functional and physical domains, and between the physical and process domains, accomplishes a number of important design tasks. First, it enables the designer to...

The concept of redundancy is common in day-to-day life. In engineering, redundancy allows a system to work safely, often by creating a backup that enters on service if the primary system fails. Redundancy in managementManagement may have the meaning of plan-B if the initial plan fails. In nature, redundancy appears in many living organisms, man inc...

The goal of the Paris Agreement to limit the increase of temperature may become an illusion. Within 20 to 30 years, Southern Europe may experience hot waves and broad dry periods. Water scarcity may turn into reality, and the Defense structures of each country must prepare for it. The Scenario has high uncertainty as well as what the response to th...

Systems with fewer design parameters (DPs) than functional requirements (FRs) are coupled or cannot achieve all their FRs simultaneously, as per Axiomatic Design's theorem 1. In that case, production processes have lower productivity and production rate than uncoupled or decoupled designs. This paper reports the upgrading of a salt washing machine...

In Information Systems (IS), the search for a good design is still a relevant issue. In IS, two sub-systems coexist, applications and data. To articulate these sub-systems, some authors opt for the CRUD matrix. Similarly, Axiomatic Design (AD) theory studies how functional requirements are related to design parameters using a design matrix. In this...

Innovation can be defined as a set of processes for altering human activity, with economic or social relevance. Innovation has been the economic driver of several companies and countries. This article presents laws with preconditions for innovation, and it proposes a framework for innovation based on Axiomatic Design (AD) theory. There are three la...

Design Engineering and Science teaches the theory and practice of axiomatic design (AD). It explains the basics of how to conceive and deliver solutions to a variety of design problems. The text shows how a logical framework and scientific basis for design can generate creative solutions in many fields, including engineering, materials, organizatio...

With the recent search for sustainable energies, the use of forest residues has never been so important and profitable. Biomass production companies are in a constant search for new methods to reuse what is otherwise seen as waste. In this context, wooden pellets have been a booming market. In Portugal, its production increased from 400 000 to 1 20...

Nowadays most of the technical drawings, to be complete, must contain information that allows a correct reading about its functionality, and simultaneously the correct interpretation for manufacturing and assembly operations: It is desirable that information allow a definition of manufacturing and assembly sequences to create conditions that lead t...

Axiomatic Design theory claims for using universal principles that allow classifying a design and choose the best one. Moreover, it helps to anticipate problems in the performance of a system. This design theory develops the design in four design domains and has two axioms: the independence axiom, and the information axiom. The probability of fulfi...

The EU F-gas regulation of 2006 and the recast of 2014 are forcing the market to reduce the use of refrigerants with high global warming potential (GWP). As a result, the production of hydrofluorocarbon (HFC) refrigerants with higher GWP decreased, making the prices of all HFC gases to increase. Any maintenance problem in a refrigeration system ask...

The Newcomen engine (1705) and the Watt engine (1769) are good examples of coupled and uncoupled designs. The Watt engine had an efficiency of about 3%, a shallow value when compared to engines of nowadays while resulting in a significant increase at those times. According to Axiomatic Design, Watt engine had a better performance than the Newcomen...

In the conceptual step of any industrial design, there is a considerable amount of decisions that directly affect the quality of the final product. These decisions are often made with lack of knowledge about the subjects, limitative trains of thought and repetition of traditional solutions. The present paper is focused on the use of Axiomatic Desig...

The introduction of cooling systems in the wine industry to control the fermentation has allowed the oenologist to produce more and more excellent wines. In this regard, the alcoholic fermentation is a target for various studies that aims at explaining the chemical reactions involved in the release of energy. The aim of this paper is to evaluate th...

In product development, creativity is the driving force for doing something that leads to innovation. A typical ideation background has three subsystems: inspiration, dematerialization and recombination. The most basic concepts of Axiomatic Design, i.e. domains, hierarchies and zigzagging, as well as the two design axioms, provide a powerful framew...

The computation of the information content of decoupled designs implies the use of conditional probability, because the existing design parameters must be adjusted in a certain order, as to fulfil all the existing functional requirements at the first trial. Nevertheless, the computation of the information content is hard to perform when the system...

The AD's design equation depicts the relationship between the functional requirements (FR) and the design parameters (DP) by the design matrix (DM), through a unique zigzag decomposition path. At the “zig part” of each level of the zigzag decomposition, the designer needs to find out the DPs that can fulfil the given FRs. This paper proposes that t...

An important discussion on the application of the Axiomatic Design Theory (ADT) is how to address coupled designs. Coupled designs are somewhat usual in engineering and call for solutions in the field of ADT. This paper addresses a class of designs where one or more functional requirements can be fulfilled by design parameters of the type “the high...

Computing the information content of coupled designs is seldom discussed in the literature, probably because the Axiomatic Design (AD) practitioners know that coupled design solutions should be avoided. On the other hand, Suh's theorem 7 states, “the information contents of coupled and decoupled designs depend on the sequence by which the DPs are c...

The sustainability in the building industry is currently a trend of the governmental policies in the EU and the USA. In the EU, the target for 2020 is to achieve net-zero energy buildings (NZEB) for the new constructions, as enforced by the 2010 recast Energy Performance Building Directive. On the other hand, it is necessary to make decisions about...

Most of the Axiomatic Design research work focuses on the design as being a relation between the functional domain and the physical domain. Yet, the outcome of a successful design results from a definition of the functional requirements that accurately reflect the customer needs. The contribution of this paper is to help defining a theoretical fram...

The most important design decisions are made in the outset of the designing process, when the knowledge about the final design solution is usually scarce and therefore uncertainty is high. According to the independence axiom of Axiomatic Design (AD), design solutions are classified in the following three basic types: uncoupled, decoupled and couple...

In common speech, the term redundant is used to label superfluous repetitions that as a rule should be avoided. Nevertheless, redundancy is a linguistic tool that can play a remarkable role in the communication of complex thoughts in both the vernacular and the erudite talking or writing, which includes the field of engineering design. In the Axiom...

Redundancy is a multifaceted issue that might be addressed according to the context, and Axiomatic Design (AD) is an appropriate approach to deal with it in engineering applications. According to the AD’s Independence Axiom, design solutions can be uncoupled, decoupled or coupled. Uncoupled and decoupled solutions are seen as “good design”, the unc...

Axiomatic design (AD) is a theory that helps to develop new design objects and allows one to evaluate the quality of designs. The aim of this paper is to apply this theory to the design of heat ventilation and air-conditioning (HVAC) systems and to come to conclusions about the design quality of some specific applications. The focus is the comfort...
