TIME-INDEXED FORMULATIONS OF THE TRUCK-TO-DOOR SCHEDULING PROBLEM AT MULTI-DOOR CROSS-DOCKING TERMINALS WITH TEMPORARY STORAGE

Abstract

A cross-docking terminal is a transshipment facility in supply chains, where products transported by inbound trucks are unloaded at inbound doors, sorted, and reloaded on outbound trucks at outbound doors. In this study we address the truck-to-door scheduling problem in a multi-door cross-docking terminal where temporary storage is considered. We propose two types of timeindexed formulation for the problem to assign trucks to dock doors and determine their arrival and departure times so that tardiness and earliness as well as unsatisfied demand are minimized. We examine the effectiveness of the proposed formulations by numerical experiment.
