The objective of the project is to provide dynamic scheduling solutions to two different services, automobile dealerships and dental clinics, in order to help them schedule in a dynamic way their daily service activities to increase customer satisfaction through the minimization of delay times. The paper serves as preliminary work for further research between the authors. Three real scheduling cases are presented: two related to different dealerships and one corresponding to a dental clinic. The principal characteristics of each of the actual scheduling systems are presented and compared, then a first approximation is established for scheduling improvements in order to increase efficiency and customer satisfaction.
