Task 1.
1). To construct bending around distribution of probability of occupation of the line in a bunch
from V, on each of which intensity of loading arrives and under a condition,
that: a) N  V; б). N>> V; в). N, V  .
2). For each used distribution to calculate average of busy lines and their dispersion.
Task 2.
On switching system the stream of calls with intensity of y=7 arrives.
а). To calculate probabilities of receipt To calls for a period [0, t *];
Task 3.
а). To calculate intensity of the arriving load of IGI step entrances for ATSKU:
Zadaniye4.
To distribute intensity of loading in the YVYKHIGI directions at IGI ATSKU step exit in the directions by method of rated coefficients of inclination (the simplified formula).
Task 5
а). necessary number of lines on all directions of search of a step of IGI, assuming fully accessible one-unit inclusion at the following norms of size of losses:
Task 7
а). To calculate on the second formula of the Erlang the size of conditional losses for all directions of search on IGI entrance, neglecting blocking and assuming that the fully accessible bunch of lines is served on system with expectation. To compare to the result received when using system with obvious losses. To present results of calculation in the form tables.
Task 6.
To construct the two-unit switching block without expansion and compression on 100 entrances and exits on square switchboards. Calculate probability of blocking.
Task 9
1. To calculate and construct dependence of number of lines V and coefficient of average use of  = y0/v from intensity arriving loadings at at size р = 0,09 and values of availability D = 10,20,40, using O. Dell´s method. To present results of calculation in the form of the table and graphics.
