Eniro 118 118 AB is Sweden's largest enlightenment company. The company provides numerous operator-based services in addition to their main service 118 118. For a service company like Eniro 118 118 AB, the telephone operators required to provide its services represents a significant proportion of the total expenses. It is therefore of great interest for the company to maintain these costs at lowest possible levels. The current business cycle along with competition from new companies and new technological possibilities for its customers has led to a situation where the importance of an efficient resource planning is becoming increasingly more significant. The dilemma lies in the complexity and versatility of the operating system. A large number of telephone operators with a unique set of core skills are working simultaneously in three different systems that interact with each other according to certain predetermined rules. To determine the number of telephone operators required at any given time for each service is very complicated.The purpose of this thesis is to provide the planning office in Sundsvall with a tool that facilitates the resource planning activities on a daily basis. This is to be done by constructing a simulation model that looks and behaves like the real system, combined with an easy-to-use user interface that allow planners to test various staffing scenarios in a safe environment.The first step was to accurately create an understanding of, and to record exactly how Eniro 118 118 AB´s telephone system is structured. A number of interviews were conducted with the supervisor at Eniro 118 118 AB, who also provided certain documentation and lots of statistics. Additional interviews with stakeholders in the planning office were made in order to clarify how the user interface was to be designed, what parameters to make adjustable, and the types of results to be presented. The simulation model has been developed in the Simul8 simulation package as requested by Eniro 118 118 AB. The model has been designed to handle all requirements defined by the company and offers a complete tool for testing different staffing scenarios in a safe environment that behaves just like the real system. The user of the simulation model specifies input data such as operator availability, phone call arrival rate, average operation time and setup time for each service. After being run, the model will present the following results; operator workload, level of service and average wait time. The simulation model communicates and is controlled by MS Excel, which means that users do not need to learn Simul8 in order to use the product. Considering Eniro 118 118 AB’s requirements for documentation, a manual has been prepared which in detail describes how the simulation has been constructed and how Simul8 operates. This is to facilitate a possible future scenario in which current conditions no longer apply and the simulation model needs to be modified. / Validerat; 20111011 (anonymous)
