    Experiential learning and cooperative education provide students with the necessary tools to succeed in the workplace by simulating their future working environment. Various studies have shown that many graduates have gaps related to their so called soft skills , which are related to teamwork, time management, working under pressure and tight deadlines. The main purpose of the inclusion of the industry expert in senior design discussions is to provide meaningful feedback through a competitive led by industry practitioners. In this simulation, the senior engineering students take on the role of actual engineering job functions, on a demanding, continuous basis for the entire school year or semester. These job functions come with all the shortcomings and particular difficulties associated with those functions in the real world. In order to develop the interpersonal professional skills needed by industry, a methodology presented in this paper is given which allows the student teams to evolve socially as departments, while supporting them with information such as Tuckman\u27s stages of group development, Myers-Briggs type indication, and recognition of the various personalities and issues arising when working in a cross-functional, team based environment. The application of this methodology and course set-up resulted in engineering graduates that were not surprised by the potential difficulties that may be encountered when ensconced in full-time, permanent engineering employment. This paper will detail some of the necessary elements required to make mechanical engineering and engineering technology capstone courses simulate real world work experience and provide students with immersion in their senior design experience which engages their soft skills . It presents a method whereby the senior design course is taught by a faculty with extensive industry experience and guided by the panel of experts made up of other faculty from the department and industry representatives. The technique(s) presented in this paper were tailored to the traditional roles of mechanical (design) engineers in the modern industrial setting, but can be reapplied to other engineering areas

    Green skills are very much needed by green industry. Nevertheless, many TVET institutions have not yet embedded green skill elements into the programme’s curriculum because it is still unclear concerning the types of green skills demanded by the green industry. Therefore, this research was conducted to identify the green skills that should be integrated into TVET curricula from the perspective of engineering lecturers in Polytechnics. The nature of this research was descriptive in which the date were collected using self-developed questionnaire. Four Polytechnics located in the East Coast, Northern, Central, and Southern of Malaysia were involved. A total of 332 engineering lecturers from three departments of engineering (Civil, Electrical, and Mechanical Engineering) were invited to participate in this research. The findings revealed that the TVET curricular should contains some of these green skills: problem solving skill related to environmental pollution,  interpretative skill on environmental phenomena, research skill on environmental issues, data collection skill, analytical skill, exploitation skill on green technology, management skill on natural resources, design skill, controlling skill on environment pollution, raw material management skill, energy saving skill, recycling skill, and reuse skill. It is suggested that Polytechnics should embed these green skills into their programme curricula in order to produce graduates who are able to meet the needs of green industry

    The purpose of this research was to examine current methodology and design tools for concurrent engineering of complex systems. A prime objective of the work was to develop an integrated CAE system for concurrent engineering and to investigate performance issues, including: Design management, productivity, modelling and simulation. The main aspects that are important in achieving total design integration have been considered and extensively studied, including: System functionality requirements, design flow, system integration, applications design, and data management. An integrated design environment has been developed utilising open architecture, commercial CAD systems and databases. An extensive range of design tools have been developed which facilitate the process of design and design management. Issues relating to transfer of data across domains (or disciplines) are addressed specifically. A "netlist" generating systems has been designed to facilitate data transfer between domains and from design to simulation. Several techniques have been assessed and fully functional system developed utilising database extraction. A database was used to assist in many areas, in particular, the strong need for efficient design data management. Various tools have been designed and developed to ensure that integration between the different environments is achieved and also to accommodate the needs of profile interchange between tools. The development of these tools comprises three major parts. In part 1, methods of design reports generation are described. Part 2 concerned with the design and development of data update tools. Part 3 is concerned with data manipulation. Design examples are used to demonstrate the performance of these tools. The work on implementing the graphical user interface (GUI) has produced a large variety of design tools and utilities. This work describes the design and development of these tools and their applications to perform design, modelling and simulation. Evaluation and performance of the software have been demonstrated based on a coupled example of electro-mechanical design. A set of design issues involving graphics constructions of both 2D schematics and 3D modelling, design tool capabilities, and design simulation was considered and performed. The results of this work have produced many specific design tools. In a broader sense, the research has examined key issues of design management in concurrent engineering and drawn important conclusions

    Get PDF
    Because of the growing demand for local skilled professionals to improve the health, energy efficiency, and sustainability of residential and commercial buildings in North Dakota, this case study reports the current situation of higher education relating to buildings in the state’s vicinity, including Minnesota, Montana, North Dakota, and South Dakota. In this region, 116 programs relating to buildings were found in 41 postsecondary institutions, and both their majors and courses were then studied with frequency lists. The frequency information was analyzed over nine sets of curriculum areas at both graduate and undergraduate levels for the four states. After the current state of buildings in North Dakota was investigated, strategies were then proposed to rectify current issues regarding higher education on buildings, including but not limited to forming a comprehensive and interdisciplinary program on buildings (e.g., architectural engineering), providing more graduate programs, developing more courses in areas that lack adequate coursework, and increasing student enrollment. These strategies will greatly promote the health, energy efficiency, and sustainability for new and existing buildings in the four-state region of Minnesota, Montana, North Dakota, and South Dakota

    Implementation challenges of annotated 3D models in collaborative design environments

    Full text link
    Recent studies in the area of collaborative design have proposed the use of 3D annotations as a tool to make design information explicitly available within the 3D model, so that different stakeholders can share information throughout the product lifecycle. Annotation practices defined by the latest digital definition standards have formalized the presentation of information and facilitated the implementation of annotation tools in CAD systems. In this paper, we review the latest studies in annotation methods and technologies and explore their expected benefits in the context of collaborative design. Next, we analyze the implementation challenges of different annotation approaches, focusing specifically on design intent annotations. An analysis of the literature suggests that the use of annotations has a positive effect on collaborative design communication as long as proper implementation practices, tools, and user interaction mechanisms are in placeCamba, J.; Contero, M.; Salvador Herranz, GM.

    Review on the leveraging of design information in 3D CAD models for subassemblies identification

    Get PDF
    In industrial manufacturing, both in the design and the production phase, the management of modern mechanical assemblies is becoming demanding due to their increasing complexity. The use of stable subassemblies concept constitutes a better alternative, which allows to independently treat smaller groups of the assembly's parts, also to achieve a parallel production. At this regard, several methods for automatic subassemblies identifi-cation, starting from the assembly CAD model, have been provided. However, most of the methodologies proposed rely on human intervention, especially in the model processing to make available essential data, while other details are ignored. After giving the definition of stable subassembly, this paper focuses on the application of stable subassemblies identification to industrial CAD models and highlights the issues arising. With the aim of ensuring a reliable CAD model analysis, starting point of the identification, the possible real engineering situations, both related to assembling methods and modelling techniques, are presented. Ap-proaches to algorithmically address them are then described, with the help of two examples of mechanical assemblies

    Integrated product relationships management : a model to enable concurrent product design and assembly sequence planning

    Get PDF
    The paper describes a novel approach to product relationships management in the context of concurrent engineering and product lifecycle management (PLM). Current industrial practices in product data management and manufacturing process management systems require better efficiency, flexibility, and sensitivity in managing product information at various levels of abstraction throughout its lifecycle. The aim of the proposed work is to manage vital yet complex and inherent product relationship information to enable concurrent product design and assembly sequence planning. Indeed, the definition of the product with its assembly sequence requires the management and the understanding of the numerous product relationships, ensuring consistency between the product and its components. This main objective stresses the relational design paradigm by focusing on product relationships along its lifecycle. This paper gives the detailed description of the background and models which highlight the need for a more efficient PLM approach. The proposed theoretical approach is then described in detail. A separate paper will focus on the implementation of the proposed approach in a PLM-based application, and an in-depth case study to evaluate the implementation of the novel approach will also be given

    Developing Project Managers’ Transversal Competences Using Building Information Modeling

    Get PDF
    The emergence of building information modeling (BIM) methodology requires the training of professionals with both specific and transversal skills. In this paper, a project-based learning experience carried out in the context of a project management course at the University of Extremadura is analyzed. To that end, a questionnaire was designed and given to students who participated in the initiative. Results suggest that BIM can be considered a virtual learning environment, from which students value the competences developed. The emotional performance observed was quite flat. Similarly, students valued the usefulness of the initiative. Students expressed a desire for the methodological change of the university classes, and thought that BIM methodology could be useful for other courses. The results obtained show a line of work to be done to improve the training of students and university teaching
