the integration of an approximate model and a clonal selection algorithm (csa) is considered to one of the most effective ways to solve complex optimization design problems in engineering. in this study, first, a process for developing an approximate model and the principles of clonal selection algorithms were presented. then, a variotherm temperature injection mold used to produce a large liqu...

Tools built in an ad hoc way and without proper models often display problems for both tool users and designers. Firstly, without systematic analysis and good understanding of the underlying software process model, we have little chance to design a tool that will adequately address user’s needs. Next, because one tool is often used in many different situations and by people who have different w...

The extensive number of engineering drawing will be referred for planning process and the changes will produce a good engineering design to meet the demand in producing a new model. The advantage in reuse of engineering designs is to allow continuous product development to further improve the quality of product development, thus reduce the development costs. However, to retrieve the existing en...

A methodology is presented to assist the synthesis of engineering decisions based on the representation of feasible space. Given a parametric model and initial specifications, the Extensive Simplex Method is proposed to traverse the extreme points of an approximate linear model. The connected extreme points are projected to a set of two-dimensional viewing planes to visualize the feasible space...

In this paper we propose an approach for the systematic integration of humancentered design (HCD) methods throughout the whole software development process called evidence-based usability engineering. We derive our approach from six claims that emphasize shortcomings and urgent requirements of current HCD practice. Instead of clinging to a fixed process model of the usability engineering proces...

A fundamental problem in the software engineering community is how to achieve a state of continuous improvement. Over the last ten years a number of studies have been made concerning various tools, methods and software process improvement project life-cycle models, but the problem persists and in many cases the software process improvement program dies off within a

Specification and design in relational databases largely use a domain-specific design approach (e.g., Entity-Relational Model) different from that used in software engineering. In software engineering, the use of UML (Unified Modeling Language) models, design patterns, and the Unified Process are the primary design and development methodology, especially in modern object-oriented software engin...
