چکیده

The Team Orienteering Problem (TOP) is defined as to find a set of vehicle walks such that the total collected reward received from visiting a subset of customers is maximized and the length of each vehicle walk is restricted by a pre-specified limit. The team orienteering problem with capacity constraint and time window(TOPCT) is an extension of the TOP where each customer has a demand and a time window, each customer must be visited in the given time window and the capacity of each vehicle is limited. In this paper, we first formulate the TOPCT problem into an integer linear programming based on network flow theory and solve it to obtain the exact optimal solution. Then we give computational results which demonstrate the efficient of the model and algorithm.
