Abstract
The article analyzes the use of automated design when designing technological processes (TP) of the floating dock construction by decomposing complex objects into separate subsystems. Development of the best possible option of the TP is crucial for the solution of technical, economic and organizational problems under specific production conditions. Therefore, a new approach to the TP design is required, and simulation and automated design (AD) appear to fit. The system approach in AD involves decomposition of the dock hull into individual components and provides a simplified solution to the design problems. In the development of AD systems, the concept of simulation is used as a conventional computational pattern. Besides, this concept defines the system of dependencies, which is a mathematical model compiled according to the conventional computational pattern. The article presents structural diagrams for the process of automated parametric design (APD) of dock structures, as well as structural and logical diagrams for the process of design of dock hull structures. Basic principles for the organization of APD of dock structures are revealed. APD primarily consists of geometric and constructive modeling of the dock hull. It is the solution to the problems of geometric and constructive modeling that provides for an effective APD of the dock structures. As demonstrated in the article, it is not sufficient to focus solely on economic criteria when designing hull structures with the use of advanced computer technologies. For example, one of the most important indicators of design quality is the strength of structures. Thus, the study presents an algorithm for computational design of ship structures with account for strength requirements. The solution to the problem of design is directly related to calculation of the minimum hull mass. When solving the problems of designing the hull structure, the cost of the material can be set as the basic target function. At a fixed value of the boundary of material fluidity, the material mass can be expressed through its cost. It is proposed to optimize the solution to the problems of automated design of the technological processes of composite dock construction with the help of a mathematical model of the dock hull. In such a way, its strength, technological and economic efficiency can be estimated.
