ABSTRACT:
An adaptive pacing algorithm based on a statistical analysis of the times of calls is used to determine when and how many calls to dial in a call origination management system. This pacing algorithm determines the number of calls to dial as an inverse function of the mean time of all calls and the standard deviation multiplied by a first constant. This first constant is a function of the ratio of nuisance calls to the number of call attempts and is not defined as a mathematical function but is, instead, determined experimentally to be .+-.0.25 of the standard deviation and varies depending on how far the ratio of nuisance calls deviates from a set level. The number of calls to dial is also an inverse function of a second constant times the ratio of the answered calls to the call attempts per session minus the maximum allowable nuisance calls. This second constant is itself a function of the mean time, ratio of answered calls to the number of call attempts during the session and the ratio of nuisance calls to the number of call attempts, but is has been determined empirically. As the session progresses, new values of the ratio of answered calls to attempts per session, the mean time and the standard deviation are computed, and these new values are used in determining the number of calls to dial.
