A theoretical framework for product relationships description over space and time in integrated design
2016
ABSTRACTThis paper presents a novel qualitative description theory in the context of integrated design, which here incorporates assembly sequence planning in the early product design stages (also called assembly oriented design – AOD). Based on a literature review of current AOD approaches, product models and mereotopology-based theories, the authors introduce a promising mereotopological theory which enables the formal product relationships description in integrated design by introducing an emerging framework, four-dimensionalism (i.e. perdurantism in philosophy). The proposed efforts aim at providing a concrete basis for describing the evolution of spatial entities (i.e. product parts) an…
Smart lighting in a historic context: a case study
2017
Purpose The purpose of this paper is to address a project for lighting an old town in Italy. Its originality lies in the holistic approach that aims to fulfil several objectives. One is to reduce energy consumption by using efficient lamps and advanced control systems; the second one is to make the network viable and useful for many purposes by integrating ICT devices; the third one is to provide a new identity to the older part of the city by using new technologies and design concepts; while the last one is to ensure street and pedestrian safety according to codes and standards. Design/methodology/approach The plan of the city of Bagheria and the stock of luminaires of the city are analys…
Integrated Design Optimization of a 5-DOF Assistive Light-weight Anthropomorphic Arm
2011
An integrated dimensional and drive train optimization method was developed for light-weight robotic arm design. The method deals with the determination of optimal link lengths and the optimal selection of motors and gearboxes from commercially available components. Constraints are formulated on the basis of kinematic performance and dynamic requirements, whereas the main objective is to minimize the weight. The design of a human-like arm, which is 10 kg in weight with a load capacity of 5 kg, is described. An integrated dimensional and drive train optimizationmethod was developed for light-weight robotic armdesign. The method deals with the determination of optimallink lengths and the opti…
Effective digital collaboration in the construction industry – A case study of BIM deployment in a hospital construction project
2015
We examine a case of successful integrated BIM-based design in a construction project.We present a set of key factors influential to enable digital collaboration in this project.Key factors identified include: change agents, new roles, cloud computing, contracts, etc.We found integrated design to depend upon changing traditional work practices.The case is an example of BIM implementation and collaborative work in the AEC industry. Building information modeling (BIM) and related digital innovations can serve as a catalyst for more transparency, tighter integration, and increased productivity in the architecture, engineering, and construction industry. Yet, many project teams struggle with ho…
Presenting a Multi-level Superstructure Optimization Approach for Mechatronic System Design
2010
Synergism and integration in the design process is what sets apart a Mechatronic System from a traditional, multidisciplinary system. However the typical design approach has been to divide the design problem into sub problems for each technology area (mechanics, electronics and control) and describe the interface between the technologies, whereas the lack of well-established, systematic engineering methods to form the basic set-off in analysis and design of complete mechatronic systems has been obvious. The focus of the current paper is therefore to present an integrated design approach for mechatronic system design, utilizing a multi-level superstructure optimization based approach. Finall…
Succeeding with Building Information Modeling: A Case Study of BIM Diffusion in a Healthcare Construction Project
2014
Technological innovations such as Building Information Modeling (BIM) offer opportunities to improve collaborative work and integration in the architecture, engineering and construction industry. However, research to date has documented how many organizations struggle with how to work based on this new technology, and many implementations fail. In this paper we present a case study of a major healthcare construction project in which the use of BIM was paramount, and where designers claim to have succeeded in integrated design. The designers organized their digital collaboration by establishing 1) change agents; 2) a cloud computing infrastructure; 3) new roles and responsibilities; 4) BIM c…
A software for the integrated design of wastewater treatment plants
1998
Abstract A software package has been developed for automated design of wastewater treatment plants. A user-friendly environment has been implemented to facilitate design tasks, allowing rapid evaluation of different alternatives as well as performing sensitivity analyses. Flexible treatment plant configurations can be established with preliminary, primary, biological and tertiary wastewater treatments, and sludge treatment units. A generalized steady-state model developed for biological processes is also included. The design process includes treatment units sizing, plant layout, hydraulic profile calculation and equipment assignment. The system capabilities for designing new plants and upgr…
In Search for an Integrated Design Basis for Audio and Haptics
2008
Audio and haptics as interaction modalities share properties, which make them highly appropriate to be handled within a single conceptual framework. This paper outlines such framework, gaining ingredients from the literature concerning cross-modal integration and embodied cognition. The resulting framework is bound up with a concept of physical embodiment, which has been introduced within several scientific disciplines to reveal the role of bodily experience and the corresponding mental imagery as the core of meaning-creation. In addition to theoretical discussion, the contribution of the proposed approach in design is outlined.
Augmenting CASE tools with hypertext: Desired functionality and implementation issues
1997
Information systems have become bigger and more complex as their support has expanded to cover larger business domains, communication and work. At the same time technical design options such as client/server architectures and graphical user interfaces have increased the size and complexity of applications. In addition, pressures to build better systems more quickly have motivated the use of integrated design environments, such as CASE. Several integration approaches such as process modeling, frameworks and hypertext technology have been proposed. Of these we consider the least analyzed, hypertext technology, in this paper. Because of the novelty of hypertext in CASE there are several unreso…
Overview of the DEMO staged design approach in Europe
2019
This paper describes the status of the pre-conceptual design activities in Europe to advance the technical basis of the design of a DEMOnstration Fusion Power Plant (DEMO) to come in operation around the middle of this century with the main aims of demonstrating the production of few hundred MWs of net electricity, the feasibility of operation with a closed-tritium fuel cycle, and maintenance systems capable of achieving adequate plant availability. This is expected to benefit as much as possible from the ITER experience, in terms of design, licensing, and construction. Emphasis is on an integrated design approach, based on system engineering, which provides a clear path for urgent R&D …
