Review Paper On Digital Manufacturing & Design

The transformation is happening through digital manufacturing and design (DM&D) – a shift from paper-based processes to digital processes in the manufacturing industry.as technology is having a huge impact on the ways products or services are designed & manufactured. Ever increasing customer demands for newer products with better features is transforming the dynamic of manufacturing towards embracing digital technology. Mass customization of products and services is preferred over mass production. There is an increased pressure upon businesses to serve an individual customer at a competitive cost comparable to the mass production cost, with shortest possible development time and production by focusing on levels of customization, quality and performance along with competitive price and value. With the advancements made in Information Technology, Material Science, Production Technologies and Supply Chain Strategies for the past 50 years’ manufacturers are well positioned to challenge the traditional methods the products are designed and manufactured. Digital manufacturing and design encompasses visualization, manufacturing simulation, ergonomic and human factor analyses, holistic view of product and process design, development and product design sensitive to the process constraints and capabilities. The next stages of the new era and next Industrial Revolution termed as INDUSTRY 4.0. This article is all about defining a transformational shift from conventional methods of manufacturing to Digital Manufacturing adopting factors like Digital Thread, Advanced Analysis, Intelligent Machining, Security in Manufacturing, Model based system Engineering and reconfigurability in manufacturing systems et

Sustainability of the chemical manufacturing industry - Towards a new paradigm?

This paper describes the current situation of the chemicalmanufacturingindustry, with special reference to Europe and looks to the future sustainability demands on the sector, and the implications of these demands for chemical engineering education. These implications include definitions of sustainability criteria for the sector and the need for transparent reporting under the Triple Bottom Line approach. The response of the education system to the sustainability agenda over the years and a number of strategies to incorporate it into courses are described. The important role of chemical (or more generally, process) engineers in delivering sustainable solutions is emphasised but this also suggests that anew way of thinking about the discipline is required. Indeed, this paper argues that the demand for a sustainable chemicalmanufacturing sector could bring about the next paradigm shift in the discipline which has been predicted for some time

Past, present and future of information and knowledge sharing in the construction industry: Towards semantic service-based e-construction

The paper reviews product data technology initiatives in the construction sector and provides a synthesis of related ICT industry needs. A comparison between (a) the data centric characteristics of Product Data Technology (PDT) and (b) ontology with a focus on semantics, is given, highlighting the pros and cons of each approach. The paper advocates the migration from data-centric application integration to ontology-based business process support, and proposes inter-enterprise collaboration architectures and frameworks based on semantic services, underpinned by ontology-based knowledge structures. The paper discusses the main reasons behind the low industry take up of product data technology, and proposes a preliminary roadmap for the wide industry diffusion of the proposed approach. In this respect, the paper stresses the value of adopting alliance-based modes of operation

Developing digital literacy in construction management education: a design thinking led approach

Alongside the digital innovations in AEC (Architectural, Engineering and Construction) practice, are calls for a new type of digital literacy, including a new information-based literacy informed by creativity, critical analysis and the theoretical and practical knowledge of the construction profession. This paper explores the role of design thinking and the promotion of abductive problem situations when developing digital literacies in construction education. The impacts of advanced digital modelling technologies on construction management practices and education are investigated before an examination of design thinking, the role of abductive reasoning and the rise of normative models of design thinking workflows. The paper then explores the role that design thinking can play in the development of new digital literacies in contemporary construction studies. A three-part framework for the implementation of a design thinking approach to construction is presented. The paper closes with a discussion of the importance of models of design thinking for learning and knowledge production, emphasising how construction management education can benefit from them

From on-line sketching to 2D and 3D geometry: A fuzzy knowledge based system

The paper describes the development of a fuzzy knowledge based prototype system for conceptual design. This real time system is designed to infer user’s sketching intentions, to segment sketched input and generate corresponding geometric primitives: straight lines, circles, arcs, ellipses, elliptical arcs, and B-spline curves. Topology information (connectivity, unitary constraints and pairwise constraints) is received dynamically from 2D sketched input and primitives. From the 2D topology information, a more accurate 2D geometry can be built up by applying a 2D geometric constraint solver. Subsequently, 3D geometry can be received feature by feature incrementally. Each feature can be recognised by inference knowledge in terms of matching its 2D primitive configurations and connection relationships. The system accepts not only sketched input, working as an automatic design tools, but also accepts user’s interactive input of both 2D primitives and special positional 3D primitives. This makes it easy and friendly to use. The system has been tested with a number of sketched inputs of 2D and 3D geometry

Challenging the Computational Metaphor: Implications for How We Think

This paper explores the role of the traditional computational metaphor in our thinking as computer scientists, its influence on epistemological styles, and its implications for our understanding of cognition. It proposes to replace the conventional metaphor--a sequence of steps--with the notion of a community of interacting entities, and examines the ramifications of such a shift on these various ways in which we think

BPM Adoption at Bilfinger

Big size corporate companies that opt for Business ProcessManagement (BPM) adoption invest a lot in BPM initiatives with theprimary focus on the identification and standardization of best practicesin the different phases of the BPM lifecycle. The business processes de-signed are usually seen as the standard way of executing the processesand tend not be adapted to specific customers' need or changing condi-tions. Furthermore, the acceptance of a paradigm shift by the end usersis an added challenge. This case introduces a success story on BPMadoption in complex environments where different organizational unitswith different needs are involved. The projects executed in different unitsrespond to specific customers’ requirements, which affects the set of pro-cesses to be designed and executed within them. We developed a novelapproach inspired by the Cynefin framework and used it to define processarchitectures and the respective business process models for a subset ofthe units. To ensure the applicability and acceptance of the new paradigmwe followed a number of well-known methodologies and practices (e.g.SCRUM and gamification). As a result, we managed to move from thetraditional function orientation to BPM orientation taking into consid-eration the flexibility needs, and we received very positive feedback fromour end users
