“…This has been reflected through the increased prevalence, use, and deployment of web-based project collaboration technologies and project extranets. Within the AEC sector, Information and Communications Technology (ICT) has revolutionised production and design (Cera et al 2002), which has led to dramatic changes in terms of labour and skills (Fruchter 1998). However, it is also important to acknowledge that the capabilities of such applications (and implementation thereof ) in predicting the cost and performance of optimal design proposals (Petric et al 2002) should enable design engineers to compare the quality of any one tentative solution against the quality of previous solutions.…”

Successful education for AEC professionals: case study of applying immersive game-like virtual reality interfaces

Background: Global competition and the transdisciplinary nature of evolving Architecture-EngineeringConstruction (AEC) activities makes it progressively important to educate new AEC professionals with appropriate skill sets. These skills include the ability and capability of not only developing routine projects, but also delivering novel design solutions and construction processes (some of which may be unknown), to feasible, surprising, or potentially patentable solutions. For example, despite recent innovations in immersive visualisation technologies and tele-presence decision-support toolkits, the AEC sector as a whole has not yet fully understood these technologies, nor embraced them as an enabler.

“…For example, Cera et al (2001) partition 3D models according to certain geometric or design features based on user assigned access control roles. "The partitioning is used to create variable level-of-detail (LOD) meshes, across both individual parts and assemblies, to provide a model suitable for access rights for individual actors within a collaborative design environment".…”

The engineering design process evolves products by a collaborative synthesis of specifications, personnel and organizations. Unfortunately, collaborative effectiveness is thwarted by existing single-user computer-aided applications like computer-aided design, computer-aided analysis, and others. These applications and associated file management systems assign editing rights to one technical person, e.g., a designer, analyst, or a process planner. In the absence of collaborative computer-aided engineering applications, we conducted a survey to establish that product collaboration is limited to interactive, either formal or ad-hoc design sessions, social communication tools, serial model sharing, terminal/screen sharing, and to conference call interactions. Current computer-aided (CAx) tools do not permit simultaneous model changes by a collaborative team editing the same model. Although over a decade of prior research has demonstrated multi-user feasibility for computer-aided applications, the architectural breadth of this research has apparently not yet compelled developers and end-users to develop and adopt new multi-user computer-aided applications devoted to product development.Why have collaborative engineering CAx tools not been commercialized for mainstream use? This paper uses several multi-user prototypes, including the first Computer-Aided Engineering multi-user prototype called CUBIT Connect, to expose additional architectural hurdles to implementing new multi-user collaborative paradigms. These challenges relate to variable algorithmic performance times, multi-threading and event driven client notification processes, distributed access level security, and model change management in design sessions.

Current product customization systems seldom consider the whole process of product customization, nor provide integrated application services for small to medium-sized enterprises (SMEs). In this paper, an ASP-based product customization service system with integrated application services is proposed for SMEs. A lifecycleoriented customization service mode is presented to smoothly drive the whole process of product customization. For supporting product customization effectively and efficiently, key technologies on distributed product resource sharing, distributed product data reorganization, and product configuration are deeply studied. A dynamic resource publishing method and a general resource evaluation model with reward measures to promote resource sharing are given. A method of XML-based data mapping for product structure tree reorganization is proposed. A parameter gray correlation degree algorithm is established for quick product configuration. To greatly meet customers' individual requirements, an interactive virtual product configuration platform is designed. Finally, product customization service system orienting to construction machinery is developed and validates the above studies.
