COST SAVING STRATEGY FOR POST OFFICE
Abstract
The paper displays a system optimization strategy that leads to cost savings for a particular post office. It involves the queuing theory used as a tool to optimize system of incoming customers passing through service areas in order to satisfy their need Using characteristics of the system, it is possible to determine the number of service compartments that are serving during the opening time so that the system is able to manage a number of incoming customers while waiting time remains acceptable for customers. The cost savings from optimizing the number of service compartments mainly relate to the wages of post office employees. By optimizing the number of working compartments according to the intensity of arriving customers, the study depicts the number of compartments needed to fulfill customer service at given time interval. Using this method, a manager can also optimize the working schedule of the employees operating in the post office compartments. The aim of this paper is to analyze the queuing system of the Bytca post office in Slovak and useknowledge from the analysis to optimize the number of compartments and thus reduce the operating costs of the post office.
