Abstract. Cross-docking is a distribution system where products transported from warehouses to
destinations are unloaded temporarily at intermediate facilities, and loaded onto outbound trucks to be
shipped to their final destination. The complexity of cross-docking operations has been considered a
problem of great interest to researchers and practitioners in the areas of Scheduling, Optimization,
Supply Chain Management, and Operations Research. In this paper, a cross-docking simulation model
is proposed to study the cross-docking problem. This problem has been addressed in the literature
previously, but was considered in a deterministic fashion and with several strong assumptions. The
contribution of our study is to present a stochastic discrete-event simulation for the problem where
several scenarios will be studied aiming at relaxing some of the assumptions set by previous work.
Finally, the study reveals some of the most important parameters that must be investigated in a crossdocking
problem, and analyzes their significance on the final results.
