Automatic Support
Detachment (ASD) provides the development and support of all
telecommunication systems for the HQ Department of the Army. The current
system was designed to handle 1500 messages per hour with an average message
size of 2000 characters, operating on a round the clock basis. The proposed
improved system would handle 6000 messages per hour.

Three models were developed, representing the Front End
Control, Message Processing and Staff Service Center Subsystems. Applications
would fall in eight categories: control programs, I/O, video display, message
processing, table subsystem, data management subsystem, offline programs, COM
subsystem.

The language could
model multi-CPU system, is easily modifiable, facilitates the linking of
several modules to form one conglomerate system, allows tracing of all of the
simulation activities. The objectives of the modeling effort were to
determine effects of hardware conversion, system design and software
modification.

A flexible interface
between the data collection effort and the PCTCS model was designed.
User-written simulation reports provide a clear picture of the “system life’
of the simulated messages. PCTCS model will be used to evaluate design
alternatives and proposed system enhancements.
