The monograph presents the results of scientific research on the optimization of engineering structures, assuming the formalization and algorithmization of design and technological solutions in the computer-aided design (CAD). The process of designing optimal engineering structures is considered as a feedback control process. Improvement of methods and means of automation for solving optimization problems, as well as problems of calculation and design of engineering structures led to the synthesis of these methods and the creation of a wide class of objects based on CAD. The monograph is intended for scientists, researchers, doctoral students, undergraduates and students.

Improved Algorithm

A new improved algorithm of Taboo Search (TS), namely, Hybrid Taboo Search (HTS) is first introduced and tried for several test functions having multiple local optima. Here, Taboo Search was improved by combining Immune Arithmetic (IA) and Simulated Annealing (SA). Several strategies to improve the TS have been presented before, but the focus here is on the novelty, availability and precision of algorithm. There are several optimization problems in computer-aided design, so the article used the improved HTS in computer-aided optimization problems, the performance of which is compared with the performance of conventional TS (TS). Results show that HTS plays an important role in solving computer-aided optimization problems with the effectiveness and higher accuracy.

In article on the basis of generalization of experience of creating in the period from 1997 to 2015 computer-aided design of various bridge structures by fifteen graduate students of the Department of Bridges and Transport Tunnels MADI (GTU) under the leadership of Doctor of Technical Sciences, Professor P.M. Salamakhin the authors proposed the concept of the development of the structure of standard programs of computer-aided design of bridge or other engineering structures according to the given optimality criterion. Given in the most general form of the complete block diagram of such programs with the detailed disclosure of the indicator of simultaneous execution of a set of requirements in all elements of the structure dependent scale in the sequential approach the minimum possible values, and also demonstrates how to determine the combination of values of all independent parameters of structures that provide the design of facilities according to the given optimality criterion. When working on the article, some provisions of earlier studies and the state of development of automation of design of bridge structures abroad are taken into account. The authors proceed from the fact that the proposed concept of development of computer-aided design of bridge and other engineering structures according to the specified criterion of optimality can and should be used as a model in the development of computer-aided design of structures with various generalized design schemes.

CASTOR is a major project which involves the development and the integration of the software of a computer aided design for hydro projects. Based on a university–industry collaboration, the project involves a number of specialties such as hydraulics, hydrology, reservoir simulation, site characterization, geotechnical engineering, structures, turbines, and computer science. The integration of all components is presented as an advantage despite the restrictions that it could create. The integration covers the basic philosophy in development strategy, the proposed design methodology for users, the sharing of utilities, and the relations with a central data base. A rigorous quality assurance plan is adapted for each module. Key words: computer aided design, hydro development projects, engineering software.
