Abstract In the concept of development of E-navigation, large control systems for navigation, navigation safety, optimization of ship operation, and cargo operations are being developed. The vector of the direction of this development leads to fully automatic management of the maritime industry and individual segments, such as navigation and terminal operations, with the transfer of unified databases to “cloud” technologies. In modern control systems, a significant number of programs for processing information flows and databases are required from external sources. The method of addressing “cloud” technologies and external storage devices, which are updated in real-time, and a complete transition from analog, analog-digital, only to digital media and information processing systems, is adopted. The method of addressing “cloud” technologies and external storage devices, which are updated in real-time, and a complete transition from analog, analog-digital, only to digital media and information processing systems, is adopted. Modern computer systems for helping the navigator in making decisions are shifting to the area of deep integration of control actions and information processing in real perception and optimization of a verified and safe algorithm of actions. The time of work with such complexes depends on the efficiency in organizing data exchange in the “man-machine” system. In the study, an algorithm was developed for deep optimization of the control complex of the ship, to minimize and create a control shell of the “man-machine” system, using the multiprogramming method to stabilize the route passage.

ABSTRACTA versatile control system, which uses standard commercial software and hardware has been developed and applied to control oxide (and carbide) MOCVD and CVD systems. The control system is implemented within a personal computer platform. The system operates in the real time Microsoft WindowsTM environment utilizing the full advantage of the sophisticated graphical user interfaces, dynamic data exchange, networking, and multitasking capabilities. We have used two different sets of commercial software to control and monitor system hardware. The first software set is INTOUCHTM, a Man-Machine interface software from WONDERWARETM in conjunction with Microsoft ExcelTM and I/O interface software. The second software set is LABVIEWTM, which is primarily a data acquisition control system from National Instruments, combined with Visual BasicTM. Both systems include a friendly interactive real-time windows-based user interface, an advanced process entry and recording spread sheet interface, alarm and security management systems, data display and recording, maintenance routines, and complete networking and remote operation capabilities. In addition, the configurations provide a flexible hardware interface that can directly interface to I/O cards in the PC's bus, as well as to most industrial Programmable Logic Controllers, various types of process controllers, I/O devices and other forms of hardware. Most importantly, the system can interface with any in-situ process monitor or higher level intelligent process control systems in order to optimize the process. Modules may be activated or deactivated as needed (even as part of the process). These systems have been used for home-built systems, as well as to retrofit a modified Spire SPI-MOCVDTM 500XT system. General process interaction and results will be discussed.
