INVESTIGATING THE TIME AND THE COST OF SOLVING CUSTOMER COMPLAINTS WITH SIMULATION AND MATHEMATICAL MODEL APPROACHES
Abstract
Companies aim to meet their customers' expectations and make them happy by producing value-added products and services. Customer satisfaction is affected by many factors. Resolving the complaint quickly and with the expected quality is one of these factors. For this, optimum resources must be provided to the complaint system. In this study, the number of people used in the complaint system and its cost were determined by evaluating the stages from the arrival of the complaints to their closure, thanks to the simulation model created. In addition, in the study, a mathematical model was established and solved by taking the exponential distribution of service times from complaint arrival to closure. Afterwards, it was compared with the simulation results under the same conditions. As a result of the comparison, it was determined that the simulation and mathematical model results were very close to each other. The difference in complaint closing time between the mathematical model with exponential distribution of service times and the simulation model solutions with exponential distribution of service times was only 0,381%. Additionally, when service times are taken as an exponential distribution, the resulting complaint closing time is 6,749% lower than that obtained with the actual distribution value of service times. The results show that taking service times as an exponential distribution is a viable option for companies. With optimum use of personnel, customer satisfaction will increase, and more efficient use of personnel will be contributed.
