Abstract
In the process of version design of structures an engineer is compelled to solve problems of parametrical synthesis (parametrical optimization). Existing design software systems contain modules of optimization. But they require the user to select a specific optimization method, used throughout the computing process, which does not always provide effective solutions. The recalculation of structure by the method of finite elements on each stage of optimization demands much time and computing. The solution to this problem is possible by using parallel computing and introducing a block of approximations, which would allow accepting a preliminary approximate solution to a problem without using FE-analysis. It can be realized using a group of intellectual agents organized as a multiagent system. A multiagent system is effective modern software, which uses the intelligent agents as the basic units. Agents can be arranged in groups and work closely together during the decision-making process. In the article the authors offer a multiagent system consisting of three types of agents in order to solve the problem of version design of structures. The agents are assigned for special functional roles: agentperformer, agent-calculator and agent-manager. The agent-performer is responsible for optimization of every element of the structure. The agent-calculator carries out design calculation by means of FE method. The agent-manager makes control over the process of task solution, interaction of agents in the system, resolves conflicts and defines current purposes of the computing system.
Существующие методы автоматизации вариантного проектирования конструкций обладают рядом недостатков: большой вычислительной емкостью из-за частого обращения к модулю МКЭ-анализа, использованием только одного поискового метода в процессе оптимизации, зависимостью результата от выбранного метода. Все это снижает эффективность производимых вычислений. Решение данной проблемы возможно путем использования методов теории агентов и построения многоагентной системы вариантного проектирования конструкций.
