Tham khảo tài liệu 'expert systems for human materials and automation part 10', kỹ thuật - công nghệ, cơ khí - chế tạo máy phục vụ nhu cầu học tập, nghiên cứu và làm việc hiệu quả | Hybrid System for Ship-Aided Design Automation 261 A database contains data about objects and systems devices and automation components from catalogs or used on ships previously built. It can provide detailed information for designer about the elements of the automation systems used on ships constructed as well as directory information on those systems and components. Knowledge base system is the automation of selected elements of the project which are implemented by the expert system based on the domain model without the use of information on ships built . Based on the domain model can be made also an adaptation of the project which takes place when the database was not found enough to like or ship found the ship has a relatively low similarity summary and the designer decides not to match an existing project for the design of self based on a knowledge base. The hierarchical structure of automation To achieve effective and transparent formal similar ships were searching the classification structure of engine room automation which is multilayered and includes the following levels the engine room systems objects control and measurement points. Fig. 2. The structure of design engine room automation on the example of fuel system For the purposes of computer processing and editing of technical documentation automation adopted a single numeric encoding systems and facilities installed in a power ships. However automation components are encoded in accordance with international standards. It was assumed that the selection of automation objects is realized within the marine systems that for most ships are as follows 262 Expert Systems for Human Materials and Automation system control and protection ME fuel system lube oil system fresh water system a system of sea water compressed air system boilers and steam system bilge system power system ballast system other. Different levels of this structure for example fuel system are shown in Figure 2. Algorithmization .
