Industrial Design of Electric Machines Supported with Knowledge-Based Engineering Systems

The demand for electric machines has increased in the last decade, mainly due to applications that try to make a full transition from fuel to electricity. These applications encounter the need for tailor-made electric machines that must meet demanding requirements. Therefore, it is necessary for small-medium companies to adopt new technologies offering customized products fulfilling the customers’ requirements according to their investment capacity, simplify their development process, and reduce computational time to achieve a feasible design in shorter periods. Furthermore, they must find ways to retain know-how that is typically kept within each designer to retrieve it or transfer it to new designers. This paper presents a framework with an implementation example of a knowledge-based engineering (KBE) system to design industrial electric machines to support this issue. The devised KBE system groups the main functionalities that provide the best outcome for an electric machine designer as development-process traceability, knowledge accessibility, automation of tasks, and intelligent support. The results show that if the company effectively applies these functionalities, they can leverage the attributes of KBE systems to shorten time-to-market. They can also ensure not losing all knowledge, information, and data through the whole development process

A Knowledge-Based Engineering System Framework for the Development of Electric Machines

The new concept industry 4.0 is a great opportunity to improve the competitiveness in a global market for small-medium size electric machinery companies. The demand for electric motors have increased in the last decade especially due to applications that try to make a full transition from fuel to electricity. These applications encounter the need for tailor-made motors that must meet demanding requirements. Therefore, it is mandatory small-medium companies adopt new technologies offering customized products fulfilling the customers’ requirements according to their investment capacity. Furthermore, simplify their development process as well as to reduce computational time to achieve a feasible design in shorter periods. In addition, find ways to retain know-how that is typically kept within each designer either to retrieve it or transfer it to new designers. To support the aforementioned issue, a knowledge-based engineering (KBE) system framework for the development of electric machines is devised. The framework is encapsulated in the so-called KBV2-model comprising the standardized macro-level framework for electrical machine and the knowledge base generation process. This thesis describes this model and the integration of KBE applications with current industrial technologies such as Model-Based Systems Engineering (MBSE), Product Lifecycle Management (PLM), multiphysics and analytical design tools. This architecture provides capability to manage and automate tasks in the development process of electric machines. The author of this work has opted to develop KBE applications following the minimum viable product principle. The KBE system framework herein presented is formalized through the experience and analysis of the development and implementation of the KBE applications. From which a guideline is provided following a sequential process in order to achieve a viable KBE system. To substantiate the process a KBE system is created that supports the development of electric motors for the elevator system industry

Increasing integration of disciplines in modern products makes it more and more a challenge to arrange collaboration efficiently and effectively. Process and product characteristics as well as the architecture of information systems used in product development have to be considered. This paper introduces a methodology for the design of collaboration situations based on principles of system analysis. First, a collaboration situation is defined and modelled regarding constituent elements in the domains process, product and system. Second, a description model for dependencies in these domains is developed. Morphological analysis was applied to derive features and characteristics of the model. Third, an improvement approach to optimize a given collaboration situation is depicted. The improvement approach comprises a sensitivity model, which explicates causal relations between the dependency features. The methodology is applied to a case study from manufacturing industry

Sustainability of e-waste Management: Egypt case study

The amount of electronic waste generated globally is alarming especially that it is on the rise. The impact of the generated amounts is not only Environmental. The electronic waste sector is unregulated in most developing countries; this results in the informal sector being heavily involved in managing and handling it. Due to the lack of regulations, informal handlers are exposed to hazardous materials that affect both their health and health of the communities living in their proximity. Moreover, the informal sector involves illegal child and women labour under harsh conditions. In addition to the social impact, the lack of regulations leads to missing major economic opportunities associated with developing a recycling industry for the safe handling and material recovery from the generated e-waste volumes. Electronic waste may contain up to 60 different materials including precious and rare-earth metals with an estimated equivalent economic value of 48 billion Euros (Baldé, Wang, Kuehr, & Huisman, 2015; Tansel, 2017). Egypt is one the countries which lack policies and regulations dedicated to e-waste, hence the Egyptian economy is missing the economic potential and job creation opportunities associated with developing the e-waste sector as well as facing major Environmental and health challenges due to the improper handling of the generated amounts. This thesis investigates the current situation of e-waste in Egypt through interviews with major stakeholders in the sector as well as a questionnaire. The thesis then proposes an adapted guideline for the sustainable management of e-waste in Egypt. The guideline is based on the international regulations and guidelines especially those of countries similar to the Egyptian socioeconomic context. Finally, the possibility of upcycling the rejects produced from the e-waste recycling processes is tested. Nonmetals represent around 70% of the total weight of the generated e-waste; these nonmetals include fiberglass and resins which are used in the manufacturing of PCBs (Kaya, 2016). In the Greater Cairo Area only, it is estimated that around 150 ton/year of PCBs are generated (Fathya Soliman & Mounir Boushra, 2017). Thus, the achieved results from upcycling the PCB powder into a composite material, which can replace marble to be used for tabletops or tiles, were a step ahead to realizing sustainable e-waste rejects handling. The produced material has an average flexural strength of about 1773 MPa compared to 1431 MPa for marble and the weight loss during abrasion test of the produced materials was between 0.13%-1.5% compared to about 8.8% for marble

Development and implementation of clinical guidelines : an artificial intelligence perspective

Clinical practice guidelines in paper format are still the preferred form of delivery of medical knowledge and recommendations to healthcare professionals. Their current support and development process have well identified limitations to which the healthcare community has been continuously searching solutions. Artificial intelligence may create the conditions and provide the tools to address many, if not all, of these limitations.. This paper presents a comprehensive and up to date review of computer-interpretable guideline approaches, namely Arden Syntax, GLIF, PROforma, Asbru, GLARE and SAGE. It also provides an assessment of how well these approaches respond to the challenges posed by paper-based guidelines and addresses topics of Artificial intelligence that could provide a solution to the shortcomings of clinical guidelines. Among the topics addressed by this paper are expert systems, case-based reasoning, medical ontologies and reasoning under uncertainty, with a special focus on methodologies for assessing quality of information when managing incomplete information. Finally, an analysis is made of the fundamental requirements of a guideline model and the importance that standard terminologies and models for clinical data have in the semantic and syntactic interoperability between a guideline execution engine and the software tools used in clinical settings. It is also proposed a line of research that includes the development of an ontology for clinical practice guidelines and a decision model for a guideline-based expert system that manages non-compliance with clinical guidelines and uncertainty.This work is funded by national funds through the FCT – Fundação para a Ciência e a Tecnologia (Portuguese Foundation for Science and Technology) within project PEst-OE/EEI/UI0752/2011"
