The simulation of a sampled-data system is described that uses a full parallel hybrid computer. The sampled data system simulated illustrates the proportional-integral-derivative (PID) discrete control of a continuous second-order process representing a stirred-tank. The stirred-tank is simulated using continuous analog components, while PID…

The decision support system (DSS) environment, the functional requirements of a DSS, and the architectural requirements of the computer systems and communications network necessary to support a DSS are discussed. Changes in the computing environment that are necessary to implement decision support systems are suggested. (Author/MLW)

A set of techniques is presented to assist administrators in forecasting the need for primary and secondary school facilities and in critically evaluating proposals to satisfy that need. Four basic components allow the analysis required to project future conditions and test alternative proposals. (1) The enrollment component forecasts the number…

A computer-based version and a manual version of a set of techniques (EA008632-633) developed to assist in forecasting the need for primary and secondary school facilities and in critically evaluating proposals to satisfy that need are evaluated in this report. The report is organized into eight chapters. Chapter 1 summarizes the project…
