The satisfying of human needs through designing technical objects requires the compromisation and settling of various conflicting criteria at different stages of the engineering design process. The need for back and forth adjustment of design specifications, concept finding, and design embodiment can be considered to be carried out in a telescopic review fashion. The present study is concerned ...

As application semantics becomes more complex and dynamic in IT systems, it is necessary to engineer the application semantics in its own lifecycle of development parallel to system engineering. The application semiotics engineering process is under study as a methodology for engineering complex and dynamic business logic in intelligent applications. It stresses the informal specification, the ...

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...

design process is one of the main processes practiced in engineering. in this paper, after demonstrating the place of engineering among the topics discussed about technology, design process is studied from the perspective of three different models. the first model, vincenti’s model, provides an abstract explanation of the design process; the second model, bucciarelli’s model, has a sociological...

In this tutorial, we compare OWL-DL reasoning and Petri net analysis for validating refinement and grounding of business processes. (1) Process refinement: Like in software engineering, the implementation of a business process involves different interacting roles, such as business expert, analyst, process architect, and developer. Each role designs and refines different abstractions of the proc...

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...
