Scheduling of inbound truck arrivals and shop-floor operation in a cross-dock platform, based on outbound trucks loading plan

Abstract

A cross-dock centre is an intermediate consolidation point in a supply chain, which links a set of suppliers with a set of customers. This logistics strategy seeks to reduce lead time, decrease stock level and make economies in transportation. In the shop floor, packages from inbound trucks are unloaded, moved across the platform, sorted by destination and loaded onto outbound trucks. The international development of the automotive industry has been supported in part by crossdocking platforms which link distant manufacturing plants with nearby first-tier suppliers. Our research is based on a case of study at one of this platforms, from an important carmaker. The majority of packages are moved directly from inbound to outbound zone, but some of them need to be repacked. Outbound trucks are considered as an assembled product, which will be manufactured (loaded) only if all components (packages) are available. Therefore, the planning process starts with outbound trucks’ loading plan optimization (high complexity due to the diversity of packing types). Shop-floor activities and inbound trucks deliveries are scheduled accordingly. We propose a linear programming model to optimize operation scheduling, respecting outbound trucks’ loading plan. The objective is to minimize storage cost, manpower cost and inbound delivery penalty cost (initial truck schedule can be modified). Constrains on the number of inbound and outbound doors and on repacking zone capacity are also included. The model is implemented in CPLEX and tested on several instances based on real-data.
