Abstract
Purpose
This paper aims to discuss how to apply the evolutionary resilience theory in the housing sector, aiming to develop an alternative resilience framework for planning social housing programmes.
Design/methodology/approach
Based on the literature review, it was developed a theoretical framework for building evolutionary resilience. Based on this framework, the outline for the empirical research was specified through interviews with 21 multidisciplinary experts. The statements of these experts were examined through content analysis, as a means to assign a set of requirements for resilient buildings.
Findings
The analysis showed that the holistic framework based on evolutionary resilience could constitute a comprehensive and innovative resilience approach. The main contribution of the set of requirements was to adapt theoretical concepts by proposing operational surrogates, enabling such knowledge to be more applicable to devising resilience to the housing sector.
Originality/value
Resilience is establishing itself as one of the top agendas on the built environment. The construction sector, however, has yet to embrace the concept and little research has been conducted on a practical approach to assess the building’s resilience. This paper presents a list of practical requirements showing that the housing sector must to build differently to have a resilient future.

Abstract
On the background of previous research work concerning a nanoscale approach to a theory of biomimetic evolutionary systems and biomimetic information processing it is shown that strictly formal‐logic based, “hard‐wired” electronic hardware misses the very physical nature of bioevolvability. A new, physics‐base concept of information, and a new concept of hierarchical, open and dissipative “evolware”, much like biosystems “wetware”, are required for developing an actually biomimetic “evolutionary automata” technology, but a basic inter‐ and intra‐level communication problem is shown to affect the whole automaton's nanostructure. The problem consists in the difficulty of setting forth causal links bridging the whole hierarchy, from the nanoscale up to the macroscopic structure‐functions.

Abstract
Purpose
The purpose of this paper is to present an approach to employ evolvable hardware concepts, to effectively construct flapping‐wing mechanism controllers for micro robots, with the evolved dynamically complex controllers embedded in a, physically realizable, micro‐scale reconfigurable substrate.
Design/methodology/approach
In this paper, a continuous time recurrent neural network (CTRNN)‐evolvable hardware (a neuromorphic variant of evolvable hardware) framework and methodologies are employed in the process of designing the evolution experiments. CTRNN is selected as the neuromorphic reconfigurable substrate with most efficient Minipop Evolutionary Algorithm, configured to drive the evolution process. The uniqueness of the reconfigurable CTRNN substrate preferred for this study is perceived from its universal dynamics approximation capabilities and prospective to realize the same in small area and low power chips, the properties which are very much a basic requirement for flapping‐wing based micro robot control. A simulated micro mechanical flapping insect model is employed to conduct the feasibility study of evolving neuromorphic controllers using the above‐mentioned methodology.
Findings
It has been demonstrated that the presented neuromorphic evolvable hardware approach can be effectively used to evolve controllers, to produce various flight dynamics like cruising, steering, and altitude gain in a simulated micro mechanical insect. Moreover, an appropriate feasibility is presented, to realize the evolved controllers in small area and lower power chips, with available fabrication techniques and as well as utilizing the complex dynamics nature of CTRNNs to encompass various controls ability in a architecturally static hardware circuit, which are more pertinent to meet the constraints of micro robot construction and control.
Originality/value
The proposed neuromorphic evolvable hardware approach along with its modules intact (CTRNNs and Minipop) can provide a general mechanism to construct/evolve dynamically complex and optimal controllers for flapping‐wing mechanism based micro robots for various environments with least human intervention. Further, the evolved neuromorphic controllers in simulation study can be successfully transferred to its hardware counterpart without sacrificing its anticipated functionality and realized within a predictable area and power ranges.

Abstract
Purpose
The purpose of this paper is to look at production and the installation of production lines, and question how to reduce investment for installation and how to organize the structure of such a line in order to use and reuse it for as many different or new types of products as possible.
Design/methodology/approach
The paper looks at some basic technological interdependencies.
Findings
The paper finds that the know‐how, the long‐term capabilities and creativity make man a very important asset in terms of economical factory operation. Evolvable production systems may in the near future turn out to be the bridging link between what one might call “the cost‐driven operation reducing the workforce” and an answer to how factory operation could be sustainable for a society and be highly profitable at the same time.
Originality/value
Evolvable assembly systems are a technological task requiring profound theoretical research and solutions. The paper is of value in listing some requirements for evolvable systems.

Abstract
Purpose
Evolvable production systems enable fully reconfiguration capabilities on the shop floor through process‐oriented modularity and multi‐agent‐based distributed control. To be able to benefit architectural and operational characteristics of evolvable systems, there is a need of a new planning approach which links shop floor characteristics and planning operations. This paper seeks to address these issues.
Design/methodology/approach
Evolvable production system has a structured methodology in itself. Consistent to this, a reference planning architecture is developed aiming to achieve agility on planning activities. Besides a workload control method is proposed and implemented as a part of the planning architecture.
Findings
First applications of evolvable systems have been implemented through European research projects. Shop floor working principles and architectural characteristics are consistent to facilitate more agility on planning activities which are framed at a planning reference architecture called demand responsive planning. As an implementation case, an agent‐based workload control method is proposed and implemented. The characteristics of EPS and proposed planning architecture enable continuous and dynamic workload control of the shop floor to be implemented.
Originality/value
This paper presents a new planning model compatible with evolvable production systems targeting to agility to demand on planning and control activities benefiting shop floor enhancements of a fully reconfigurable system which enables to relax constraints imposed from production systems to planning. In addition, a continuous and dynamic workload control method is proposed and implemented.

Abstract
Purpose
Current major roadmapping efforts have all clearly underlined that true industrial sustainability will require far higher levels of systems' autonomy and adaptability. In accordance with these recommendations, the Evolvable Assembly Systems (EAS) has aimed at developing such technological solutions and support mechanisms. Since its inception in 2002 as a next generation of production systems, the concept is being further developed and tested to emerge as a production system paradigm. The essence of evolvability resides not only in the ability of system components to adapt to the changing conditions of operation, but also to assist in the evolution of these components in time. Characteristically, Evolvable systems have distributed control, and are composed of intelligent modules with embedded control. To assist the development and life cycle, a methodological framework is being developed. After validating the process‐oriented approach (EC FP6 EUPASS project), EAS now tackles its current major challenge (FP7 IDEAS project) in proving that factory responsiveness can be improved using lighter multi‐agent technology running on EAS modules (modules with embedded control). The purpose of this paper is to detail the particular developments within the IDEAS project, which include the first self re‐configuring system demonstration and a new mechatronic architecture.
Design/methodology/approach
The paper covers the development of a plug & produce system for FESTO AG. The work covers the background methodology and details its constituents: control system, architecture, design methodology, and modularity. Specific detail is reserved for the configuration approach which integrates several tools, and the commercially available control boards. The latter have been specifically developed for distributed control applications.
Findings
The paper details probably the first self‐configuring assembly system at shop‐floor level. This is one of the very first industrial plug & produce systems, in which equipment may be added/removed with no programming effort at all.
Research limitations/implications
The paper reports the findings and development carried out within the framework of a single project. It also clarifies that the solution is not a general panacea for all the issues within assembly.
Practical implications
The implications are quite large as the work proves the validity of an approach that could change our way of designing and building assembly systems. In the words of an industrial partner, this is “a new way of engineering assembly systems”.
Social implications
Should this approach be used in industry then the implications could be huge. It would, for example, mean that new services are created, whereby assembly system modules are leased to users through a network of depots, rather than bought at a high cost. The system modules also have a far longer lifespan, implying very good ecological solutions.
Originality/value
The highly original paper describes what is probably one of the very first projects to show that distributed control at shop‐floor level is viable and technologically feasible.

Abstract
Purpose
This roadmap is primarily concerned with the adaptive assembly technology situation in Europe, a topic of particular interest as assembly is often the final process within manufacturing operations. Being the final set of operations on the product, and being traditionally labour‐intensive, assembly has been considerably affected by globalisation. Therefore, unlike most technology roadmaps, this report will not focus solely on particular technologies, but will strive to form a broader perspective on the conditions that may come to influence the opportunities, including political aspects and scientific paradigms. The purpose of this paper is to convey a complete view of the global mechanisms that may come to affect technological breakthroughs, and also present strategies that may better prepare for such a forecast.
Design/methodology/approach
The paper describes a technological roadmap.
Findings
This paper provides a complete overview of all aspects that may come to affect assembly in Europe within the next 20 years.
Originality/value
The paper gives an original Evolvable Ultra Precision Assembly Systems FP6 project result which will be of general interest for strategic R&D.

Abstract
Designing learning environments is increasingly about mediating between the interactions in real and virtual space of largely self-organising learning communities. Traditional ways of briefing designers are less and less proficient, as the demands made on space become less timetabled, more probabilistic. ‘learning landscapes’ 1 are proposed in which clusters of activity can be seen to be taking place across a field, that activity can be browsed, audited and fully engaged with. Such organic flows of interest and concentration are hindered by traditional demarcated space models, and attempts to enable the flows through ‘flexible’ interlinking of rooms fail.
There is evidence 2 that the organic interactions between learners grow exponentially when these learners are connected together as virtual communities in open, robust virtual platforms. But this works best when these interactions are grounded from time to time in real places. How can designers best provide spaces that support learning in real and virtual space? Should design teams be composed of people with skills in devising real and virtual space?
Increasingly the answer is ‘yes’, and this places strains on procurement processes. Built form can take a long time to deliver. So can virtual platforms take time to devise and make operable. Can these processes be aligned? The concepts for RMIT’s Design Hub, a physical design research platform, were developed through research conducted twelve years before the building was completed. Many of the gap years were taken up with establishing the financial basis for constructing the Hub. During this time the concepts were validated by testing with various potential user groups, and a further tranche of international investigations validated the level of innovation being sought. The process for RMIT’s Swanston Academic Building (SAB) was smoother and shorter, but it involved a year in which a ‘learning landscape’ concept was moulded through intensive work with user client focus groups.
Neither of these projects has a virtual doppelganger, though both have sophisticated and evolvable IT systems. The Hub embeds a process of curating research interaction and dissemination that is hampered by this fact. The mediated learning landscape of the SAB falls short of the originating concepts, – because space constraints did not allow for an undivided, flowing landscape. A well designed virtual counterpart could have provided what the insertion of walls has obscured. Should all future innovative learning and researching environments have a virtual counterpart from the outset?
There is an emerging trend for such paired environments in creative city thinking and in museums. Surely briefing and procuring real and virtual environments in tandem will enliven future space use in universities?

Abstract
Purpose
The purpose of this paper is to understand the usefulness of an agile social learning method in higher education to build capacity for sustainable development at the community level. Social learning methods intend to empower students (and instructors) to work together in connection with real-life issues – combined with acquiring a conceptual understanding – to analyze issues at hand and work out solutions. The agile format of the method was aimed at a subject that is adaptive and responsive to change to empower the students to take action toward sustainable development.
Design/methodology/approach
This study was based on a case study methodology where the running of the subject was documented and analyzed for two years. The target student group was maritime professionals who had an interest or were in a position to work with developing sustainable solutions in their home organizations (mostly in developing countries).
Findings
The results of the analysis indicate how the students learned about environmental, social and economic spheres of sustainable development and their linkages; how the subject format stimulated the students to develop different “learning paths” between the three spheres of sustainable development, which enabled a multi-faceted understanding of sustainable development issues; and, finally, how the students were able to design evolvable sustainable development solutions.
Originality/value
The results indicate both the novelty and usefulness of the agile social learning method to build capacity for sustainable development through the subject designed for higher education.
