Mprolog as an expert system development tool
The difficult process of designing expert systems has caused the development of many useful expert system design tools. A new tool, called MPROLOG, has been developed into an expert system tool by giving the designer the power of a programming language, PROLOG, along with a method for specifying …

Control system design using artificial intelligence
Successful multivariable control system design demands knowledge, skill and creativity of the designer. The goal of the research described in this dissertation was to investigate, implement, and evaluate methods by which artificial intelligence techniques, in a broad sense, may be used in a design …

Structured Approach to Industrial Control System Design
The design of complex control systems for industrial processes is in general still based on experience and trial and error rather than on systematic process analysis and control system design. Typically control systems in the process industry comprise either single PID control loops with clear …

Statistical risk estimation for communication system design
Spacecraft are complex systems that involve many subsystems and multiple relationships among them. The design of a spacecraft is an evolutionary process that starts from requirements and evolves over time. During this process, changes can affect mass and power at component, subsystem, and system …

A tool for model-based engineering
In many hard real-time avionics systems, more and more features are being added to faster but cheaper hardware. Thus, hardware resources such as computation and network bandwidth are increasingly being shared by multiple applications, leading to rapid increases in the size and complexity of the …
