1. Abstract Due to rise of environmental awareness and enactment of legislation in recent years, products that reach their end-of-life need to be collected, disassembled and reused / recycled. However, since every component that comprises a product is not reused / recycled from a cost effective standpoint, a product needs not be completely disassembled and only components to be reused / recycle...

Dynamic computer based support tools for the conceptual design phase have provided a long-standing challenge to develop. This is largely due to the ‘fluid’ nature of the conceptual design phase. Design evaluation methods, which form the basis of most computer design support tools, provide poor support for multiple outcomes. This research proposes a stochastic-based support tool that addresses t...

Source Integration is one of the core problems in Data Warehousing. Two critical factors for the design and maintenance of applications requiring Source Integration, and in particular Data Warehouse applications, are conceptual modeling of the domain, and reasoning support over the conceptual representation. We present a novel approach to conceptual modeling for Source Integration, which allows...

Computational systems in the field of building technology are, at present, mainly employed as electronic catalogs for the retrieval of technological information (content providers). However, the massive amount of information associated with building design demands explicit knowledge about the way various information pieces relate one to another in order to be able to achieve an intelligent use ...

Effective data warehouse design requires a conceptual modeling phase. This paper describes a data warehouse design method based on the conceptual, logical and physical levels. The conceptual phase creates an UML model. To this end, UML is enriched with multidimensional concepts. The logical phase maps the enriched UML model into a multidimensional one. The physical phase maps the multidimension...

As a subset of the Information systems (IS) discipline, Decision Support Systems (DSS) development research needs a broader conceptual lens in order to evaluate design qualities specific to DSS. This paper presents a development-oriented approach for evaluating DSS applications. Based on a design science mental model proposed by Peffers, Tuunanen, Rothenberger and Chatterjeea (2008), our study ...

The focus of this paper is database design in the context of converting a conceptual data model into an internal representation. For a given conceptual data model, an access pro-le speciies statistical information about (retrieval and update) requests to be performed, while a data proole speciies a statistical characterization of the database contents. The corresponding time/space trade-oo and ...

We are dealing with the problem of space layout planning here. We present an architectural conceptual CAD approach. Starting with design specifications in terms of constraints over spaces, a specific enumeration heuristics leads to a complete set of consistent conceptual design solutions named topological solutions. These topological solutions which do not presume any precise definitive dimensi...

This study describes a multi-agent system that acts as a mediator between the designer and the information environment. The system enables designers to locate and retrieve information from distributed resources. There are three types of agents in the proposed model. The duser agentsT consist of designers, engineers, and technicians. The dinformation agentsT include various knowledge domains as ...
