1. In an automatic call distribution system having a plurality of diverse application call processors, a method for directed call control scheduling comprising the steps of:

  • a. determining if a call request is present and if there is not a call request present repeating step a, otherwise continuing to step b;

    b. determining if one of said application call processors has been assigned to the call request and if an application call processor has been assigned to the call request then continuing to step c, otherwise proceeding to step d;

    c. terminating the call request, updating application call processor utilization data table entries and returning to step a;

    d. using a computed response time data T(i) for i=1 to N for each of the 1 to N application call processors of class i with performance data of S(i) for i=1 to N of each of the 1 to N application call processors in class i and utilization data U(i) for i=1 to N to find one application call processor that has a minimum response time T(j) of the j-th application call processor of the plurality of application processors to fulfill the call request;

    e. determining if the minimum response time T(j) is greater than maximum allowable response time τ and

    if the minimum response time T(j) is greater than maximum allowable response time τ

    continuing to step f, otherwise proceeding to step g;

    f. shedding said call request and returning to step a;

    g. updating expected utilization of U(j) of the j-th application processor for call processing and assigning said call request to the j-th application processor for call processing; and

    h. returning to step a.
