Optimal dynamic scheduling of a power generation system to satisfy multiple criteria
Article Abstract:
A computer algorithm for the optimal scheduling of generators in a power system is presented and tested. The algorithm, based on goal programming, automatically and dynamically schedules the output of each generator in the system for optimal operation. The optimal operation can take into consideration multiple objectives such as economy, security, and reduction of pollution as well as practical constraints. To validate and test the algorithm, an example system of five generators, 10 busses, and 11 transmission lines is optimized for two objectives: minimal generation cost and minimal emission of nitrous oxides (NOx). Hourly changes in total power demand in the range of 90 percent to 110 percent are considered together with a constraint of maximum permissible total NOx emission. Other practical equality and inequality constraints are incorporated into the optimization algorithm. The simulation results demonstrate that the outputs of the generators can be changed smoothly and dynamically. Furthermore, using the algorithm, computer control is practicable either by direct on-line optimization or by using the feasible operation region generated as a small data-base by off-line computation.

Automatic model generation for production-distribution systems using natural language
Article Abstract:
Simulation is a powerful tool for system analysis and decision support. Managers need sophisticated simulation tools for support time-critical decisions. This paper presents an intelligent simulation environment which provides the manager with analytical support through a user friendly interface. Using natural language, the user can build system dynamics simulation models. The application domains is multi-level production distribution systems. DYNAMO code for the model is automatically generated. (Reprinted by permission of the publisher.)

Evans & Sutherland Announce an Order for a Multichannel NOVOVIEW SP3T Computer Image Generation System
Article Abstract:
Rediffusion Simulation Inc. has placed an order with Evans & Sutherland Computer Corp. for a multichannel NOVOVIEW SP3T image generation system. Rediffusion will add projection and extra simulation equipment to the SP3T at the delivery site, the Sikorsky Aircraft Division of United Technologies. The system provides visual scenes in real time and will be used in the design of helicopters. The system will cost over $1.3 million.
