Spacecrafts constellation increasing and using few-point its control technology cause increasing
workload of both control facilities and planning department, which allocates these facilities. It is necessary
to timely predict of the situation of allocation control facilities for spacecrafts to compensate
these factors. The factors influenced on evaluated parameters of the situation of allocation control facilities
for spacecrafts and their influence are analyzed. The main parameters of the situation are discussed.
It is shown that the workload of planning department depends a lot from a number of conflicts
during allocation control facilities for spacecrafts. The model of prediction workload of planning department
was developed and implemented in MatLAB. The description of its unites is given. A series
of model experiments was performed. Some numeric probabilistic characteristics of workload of
planning department were obtained. So, the number of conflicts increasing progressively during increasing
the number of spacecrafts. The largest number of conflicts is observed at the least number
of control facilities. Note that the number of conflicts can vary significantly for the same number of
spacecrafts and control facilities. However, the trend of progressive growth of the number of conflicts
during increasing the number of spacecrafts is still preserved. In general case, the probability density
of the number of conflicts tends to the normal distribution law.
