An information model supporting core systems engineering design data is presented. The model provides, in conjunction with STEP (ISO 10303) framework services, an infrastructure that facilitates data exchange between design tools used in the systems engineering process. The model has been developed within the SEDRES project (ESPRIT 20496) and will serve as a seed for the standardisation of a fu...

A new information system landscape is emerging that will be more model-centered than object-oriented, characterized by many models of low granularity and high abstraction. These models may describe various aspects of a system such as products, structural organization and processes. This latter category may be refined in manufacturing, software and business processes for example. Each of these s...

This paper will review and critique the recent telecommunications proxy cost models that have been developed for the industry. While these cost models go into great detail on the engineering aspect of the telephone network, they lack a fundamental understanding of economics and finance, i.e. they fail to apply the appropriate, traditional techniques of engineering economics. Some do not use dis...

Within the domain of information systems, one of the main technological moves we may presently observe in industrial circles is the paradigm shift from object composition to model transformation. This is happening at a very fast pace. Among the concrete signs of this evolution one may mention the ongoing change at the Object Management Group from OMA (Object Management Architecture) to MDA (Mod...

Fab-less business model in semiconductor industry has led to serious concerns about trustworthy hardware. In untrusted foundries and manufacturing companies, submitted layout may be analyzed and reverse engineered to steal the information of a design or insert malicious Trojans. Understanding the netlist topology is the ultimate goal of the reverse engineering process. In this paper, we propose...

Nowadays in highly competitive precision industries, the micromachining of advanced engineering materials is extremely demand as it has extensive application in the fields of automobile, electronic, biomedical and aerospace engineering. The present work addresses the modeling and optimization study on dimensional deviations of square-shaped microgroove in laser micromachining of aluminum oxide ...

new product development (npd) is described in the literature as the transformation of a market opportunity into a product available for sale. in the automotive industry, within the context of iso/ts16949:2002 (the automotive quality management system international standard),  these related to the product realization process (prp) which consists of three main phases such as planning, implementat...

This paper examines the reasons for design iteration and describes models of design iteration. Iteration is the process of repeating tasks within a design project, and is common to all types of engineering design. Iteration is typically necessary for two reasons: an unexpected failure of a design or prototype to meet established criteria; and an expected response to information which was genera...
