Abstract
This study focuses on a customer visit scheduling problem of a salesperson working in a public bus manufacturer in Türkiye. The salesperson visits the customers to obtain information about their future sales plans and to make sales contracts. The salesperson must visit each customer at least once in the planning horizon and can make multiple visits to a customer with a high priority. The salesperson develops monthly customer visit schedules by considering the customer priorities and predefined intercity tours. In the realization of the schedule, priority of a customer may change occasionally due to some events such as a rapid purchase decision notified by a private call. In this case, the schedule should be modified to visit such customers as soon as possible. In this study, we have developed a mathematical model for rescheduling and proposed alternative rescheduling strategies for the problem. In the computational study, we have generated a set of problem instances to test the performances of the proposed rescheduling strategies. We have compared the proposed strategies under a set of dynamic scenarios and developed managerial insights for the dynamic customer visit scheduling problem.
