Knowledge Based Engineering

Purpose – The purpose of this paper is to focus on developing a knowledge-based engineering (KBE) approach to recycle the knowledge accrued in an industrial organization for the mitigation of unwanted events due to human error. The recycling of the accrued knowledge is vital in mitigating the variance present at different levels of engineering applications, evaluations and assessments in assuring systems’ safety. The approach is illustrated in relation to subsea systems’ functional failure risk (FFR) analysis. Design/methodology/approach – A fuzzy expert system (FES)-based approach has been proposed to facilitate FFR assessment and to make knowledge recycling possible via a rule base and membership functions (MFs). The MFs have been developed based on the experts’ knowledge, data, information, and on their insights into the selected subsea system. The rule base has been developed to fulfill requirements and guidelines specified in DNV standard DNV-RP-F116 and NORSOK standard Z-008. Findings – It is possible to use the FES-based KBE approach to make FFR assessments of the equipment installed in a subsea system, focussing on potential functional failures and related consequences. It is possible to integrate the aforementioned approach in an engineering service provider’s existing structured information management system or in the computerized maintenance management system (CMMS) available in an asset owner’s industrial organization. Research limitations/implications – The FES-based KBE approach provides a consistent way to incorporate actual circumstances at the boundary of the input ranges or at the levels of linguistic data and risk categories. It minimizes the variations present in the assessments. Originality/value – The FES-based KBE approach has been demonstrated in relation to the requirements and guidelines specified in DNV standard DNV-RP-F116 and NORSOK standard Z-008. The suggested KBE-based FES that has been utilized for FFR assessment allows the relevant quantitative and qualitative data (or information) related to equipment installed in subsea systems to be employed in a coherent manner with less variability, while improving the quality of inspection and maintenance recommendations.

Purpose This paper aims to develop a knowledge-based (KB) system for Lean Six Sigma (LSS) maintenance in environmentally sustainable buildings (Lean6-SBM). Design/methodology/approach The Lean6-SBM conceptual framework has been developed using the rule base approach of KB system and joint integration with gauge absence prerequisites (GAP) technique. A comprehensive literature review is given for the main pillars of the framework with a typical output of GAP analysis. Findings Implementation of LSS in the sustainable building maintenance context requires a pre-assessment of the organisation’s capabilities. A conceptual framework with a design structure is proposed to tackle this issue with the provision of an enhancing strategic and operational decision-making hierarchy. Research limitations/implications Future research work might consider validating this framework in other type of industries. Practical implications Maintenance activities in environmentally sustainable buildings must take prodigious standards into consideration, and, therefore, a robust quality assurance measure has to be integrated. Originality/value The significance of this research is to present a novel use of hybrid KB/GAP methodologies to develop a Lean6-SBM system. The originality and novelty of this approach will assist in identifying quality perspectives while implementing different maintenance strategies in the sustainable building context.

Study Context

Purpose The 2008 global financial crisis showed that the ability to innovate is a key management skill and that approaches to assessing the innovation capability of small- and medium-sized enterprises (SMEs) need to be as realistic as possible. This study aims to address the latter practical need through a sociotechnical approach. Design/methodology/approach Based on a combined use of cognitive mapping and the Decision EXpert (DEX) technique, and grounded on the insights generated by a panel of SME managers and entrepreneurs in two intensive group meetings, a knowledge-based assessment system for evaluating SMEs’ innovation capability was created, tested and validated. Findings The knowledge-based assessment system identified the most innovative SMEs in a sample of companies. The “plus-minus-1” and dominance analyses carried out provided further support for the results. Research limitations/implications The proposed system is extremely versatile but process-oriented and idiosyncratic in nature, meaning that extrapolations to other contexts need to be done with due caution. Practical implications The panel of SME decision makers agreed that the system improves the current methods used to evaluate SMEs’ innovation capability, contributing to a more informed perspective on management issues. The panel members also noted that the proposed system functions as a learning mechanism, facilitating the development of well-focused suggestions for improvements SMEs can make. Originality/value The integrated use of cognitive maps and rule-base decisions contributes to a better understanding of how to assess SMEs’ innovation capability. No prior work reporting the integrated use of these two techniques in this study context has been found.

Purpose The purpose of this technical paper is to evaluate the emerging standard “Allotrope Data Format (ADF)” in the context of digital preservation at a major US academic library hosted at Brigham Young University. In combination with the new information management system ZONTAL Space (ZS), archiving with the ADF is compared with currently used systems CONTENTdm and ROSETTA. Design/methodology/approach The approach is a workflow-based comparison in terms of usability, functionality and reliability of the systems. Current workflows are replaced by optimized target processes, which limit the number of involved parties and process steps. The connectors or manual solutions between the current workflow steps are replaced with automatic functions inside of ZS. Reporting functionalities inside of ZS are used to track system and file lifecycle to ensure stability and data preservation. Findings The authors find that the target processes leveraging ZS drastically reduce complexity compared to current workflows. Archiving with the ADF is found to decrease integration complexity and provide a more robust data migration path for the future. The possibility to enrich data automatically with metadata and to store this information alongside the content in the same information package increases reusability of the data. Research limitations/implications The practical implications of this work suggest the arrival of a new information management system that can potentially revolutionize the archiving landscape within libraries. Beyond the scope of the initial proof of concept, the potential for the system can be seen to replace existing data management tools and provide access to new data analytics applications, like smart recommender systems. Originality/value The value of this study is a systematic introduction of ZS and the ADF, two emerging solutions from the Pharmaceutical Industry, to the broader audience of digital preservation experts within US libraries. The authors consider the exchange of best practices and solutions between industries to be of high value to the communities.

The Semantic Web approach based on the ontological representation of knowledge domains seems very useful for improving document management practices, the formal and machine-mediated communication among people and work team and supports knowledge based productive processes. The effectiveness of a semantic information management system is set by the quality of the ontology. The development of ontologies requires experts on the application domain and on the technical issues as representation formalism, languages, and tools. In this chapter a methodology for ontology developing is presented. It is structured in six phases (feasibility study, expliciting of the knowledge base, logic modelling, implementation, test, extension, and maintaining) and highlights the flow of information among phases and activities, the external variables required for completing the project, the human and structural resources involved in the process. The defined methodology is independent of any particular knowledge field, so it can be used whenever an ontology is required. The methodology for ontology developing was implemented in a prototypal workflow management system that will be deployed in the back office area of the SIMS (Semantic Information Management System), a technological platform that is going to be developed for the research project DISCoRSO founded by the Italian Minister of University and Research. The main components of the workflow management system are the editor and the runtime environment. The Enhydra JaWE and Enhydra Shark are well suited as they implement the workflow management standards (languages), they are able to manage complex projects (many tasks, activities, people) and they are open source.

PurposeThe engineering education accreditation (EEA) is a principal quality assurance mechanism. However, at many education institutions, the most labor-intensive work of EEA process is accomplished manually. Without the support of computer and information technology, the EEA process leads to high labor intensity, low work efficiency and poor management level. The purpose of this paper is to build a complex network model and realize an information management system of talent training program for supporting the EEA process.Design/methodology/approachBased on polychromatic graph (PG), this paper builds a network model of talent training program for engineering specialty. The related information and data are organized and processed in this network model. From the bidirections of top-down and bottom-up, the user requirements are retrieved automatically in logic layer. Together with the specialty of mechanical engineering, the proposed PG-based network modeling method is applied and the corresponding information management system is realized.FindingsThe study results show that the PG-based network modeling method takes full advantages of the strong simulation ability of PG to model the complex network system and has some unique merits in formal expression of problem, efficient processing of information and lightweight realization of system. Further, the information management system of talent training program can reduce the tedious human labor and improve the management level of EEA process dramatically.Originality/valueThis paper proposes a PG-based network modeling method, in which the nodes and the edges can be painted by some unified colors to describe the different kinds of activities and the various types of interactions. Theoretically, this modeling method does not distinguish the activities, the interactions and their properties in graphic symbol and the problem size is diminished about a half. Furthermore, this paper provides an effective experience and idea to the education institutions for implementing the engineering education accreditation, increasing the education management efficiency and promoting the talent training quality.

Purpose This paper aims to present a knowledge-based fuel system, implementation and application, oriented towards its use in aircraft conceptual design. Design/methodology/approach Methodology and software tools oriented to knowledge-based engineering applications (MOKA) is used as a foundation for the implementation and integration of fuel systems. Findings Including fuel systems earlier in the design process creates an opportunity to optimize it and obtain better solutions by allocating suitable locations in an aircraft, thereby reflecting on the centre of gravity of the aircraft. Research limitations/implications All geometries are symbolic, representing a space allocation inside the aircraft for the fuel system. A realistic representation of the real components could be realized in detail design. Practical implications Fuel weight is a significant part of take-off weight and decisive in aircraft sizing and range estimations. The three-dimensional geometry provides a better estimation of the volume that is available to allocate the necessary entities. It also provides fast measures for weight and balance, fuel capacity, relative tank positions and a first estimation of piping length. Originality/value Fuel systems appear early in the design process, as they are involved in several first estimations. By using a knowledge-based engineering approach, several alternatives can be visualized and estimated in the conceptual design process. Furthermore, using the weights and centre of gravity at different angles of pitch and roll of each fuel tank, the aircraft could be optimized for handling qualities by using automatically generated system simulation models.
