AbstractSince the end of the 1990s, there has been an increasing interest in the application of artificial intelligence (AI) planning techniques to solve real-life problems. In addition to characteristics of academic problems, such as the need to reason about actions, real-life problems require detailed knowledge elicitation, engineering, and management. A systematic design process in which Knowledge and Requirements Engineering tools play a fundamental role is necessary in such applications. One of the main challenges in such design process, and consequently in the study of Knowledge Engineering in AI planning, has been the analysis of requirements and their subsequent transformation into an input-ready model for planners. itSIMPLE is a research project dedicated to the study of a project process to support the design phases of real-life planning models. In this paper, we give an overview of itSIMPLE focusing on the main translation processes among a minimal set of representations: from requirements represented in Unified Modeling Language (UML) to Petri Nets and from UML models to planning domain definition language for problem solving.

In the design process of maize combine harvester in China, there are characteristics of customization and high demand for diversification. Aiming at the problems of long design and development cycle, the structural design method of maize combine harvester header based on knowledge engineering is put forward, and the header of maize combine harvester is designed rapidly. Firstly, based on the design standards and specifications of agricultural machinery, the general design process of maize ear harvester header is determined. Secondly, according to the design knowledge and experience, the design method of the core parts of the header is determined, and an example model is established. Finally, based on the platform of MFC and Creo, integrating the design knowledge base, inference engine and parametric model, a rapid design system of maize ear harvester header is constructed. The rapid design of maize ear harvester header is realized, and the design and development efficiency of maize ear harvester header is improved so as to provide technical reference and support for improving the intelligent level of typical complex agricultural machinery equipment in China.

AbstractThe volunteer siting of disposal facilities for vitrified high-level radioactive waste (HLW) and TRU waste in Japan results in a particular need for flexibility to allow repositories to be tailored to specific sites. Instead of a single reference concept, a “catalogue” of designs for individual repository components is being developed, which can then be combined to form optimum solutions for particular site boundary conditions. As highlighted in a companion paper – Makino et al: Supporting Development of Practical Designs for a Japanese HLW Repository –, which puts the repository design process in the context of the Japanese HLW programme, the complexity of this work justifies use of advanced Knowledge Engineering approaches. In this paper three components are described – development of the knowledge base, assessing tacit system understanding and production of innovative solutions to resolve conflicts between requirements.

Fibre Metal

Fibre Metal Laminates (FML) are a member of the hybrid materials family, consisting of alternating metal layers and layers of fibres embedded in a resin. Improved damage resistance and tolerance result in a significant weight and maintenance cost reduction compared to aluminium. FML also give the aircraft engineer additional design freedom, such as local tailoring of laminate properties. However, experience has shown that FML’s provide the aircraft manufacturer with many challenges as well. With increasing complexity of the structure, requirements from different disciplines within the engineering process will start to interfere, resulting in conflicts. This article discusses the current engineering process of FML fuselage panels as applied at Stork/Fokker Aerospace (FAESP). A case study is presented, clarifying the current design process and the way requirements start to interfere during the engineering process. A new approach based on Knowledge Engineering is discussed, implementing knowledge from engineers from all disciplines in an early stage of the design process. An automated design approach for FML fuselage panels is presented, using the same design parameters as the current approach. Because of the high complexity of the design, requirements start to conflict. Fulfilling all requirements with a traditional engineering approach results in an iterative and time consuming process. Automation of the design process, integrating knowledge and requirements from all disciplines, results in a fast and transparent design approach.

Required Quality

Designing an ontology that meets the needs of end-users, e.g., a medical team, is critical to support the reasoning with data. Therefore, an ontology design should be driven by the constant and efficient validation of end-users needs. However, there is not an existing standard process in knowledge engineering that guides the ontology design with the required quality. There are several ontology design processes, which range from iterative to sequential, but they fail to ensure the practical application of an ontology and to quantitatively validate end-user requirements through the evolution of an ontology. In this paper, an ontology design process is proposed, which is driven by end-user requirements, defined as Competency Questions (CQs). The process is called CQ-Driven Ontology DEsign Process (CODEP) and it includes activities that validate and verify the incremental design of an ontology through metrics based on defined CQs. CODEP has also been applied in the design and development of an ontology in the context of a Mexican Hospital for supporting Neurologist specialists. The specialists were involved, during the application of CODEP, in collecting quality measurements and validating the ontology increments. This application can demonstrate the feasibility of CODEP to deliver ontologies with similar requirements in other contexts.

The brand is a powerful representational and identification-led asset that can be used to engage staff in creative, sustainable and developmental activities. Being a brand the result of, foremost, a design exercise, it is fair to suppose that it can be a relevant resource for the advancement of design literacy within organisational contexts. The main objective of this paper was to test and validate an interaction structure for an informed co-design process on visual brand artefacts. To carry on the empirical study, a university was chosen as case study as these contexts are generally rich in employee diversity. A non-functional prototype was designed, and walkthroughs were performed in five focus groups held with staff. The latter evidenced a need/wish to engage with basic design principles and high willingness to participate in the creation of brand design artefacts, mostly with the purposeof increasing its consistent use and innovate in its representation possibilities, whilst augmenting the brand’s socially responsible values.
