Cross docking scheduling to minimize the storage cost: a polynomial special case
نویسنده
چکیده
At cross docking terminals, products from incoming trucks are sorted according to their destinations and transferred to outgoing trucks using a small temporary storage. Such terminals allow companies to reduce storage and transportation costs in a supply chain. This paper focuses on the operational activities at cross docking terminals. We consider the trucks scheduling problem with the objective to minimise the storage usage during the product transfer. We show that a simplification of this NP-hard problem in which the departure sequences of incoming and outgoing trucks are fixed is polynomially solvable and propose a dynamic programming algorithm for it. The results of numerical tests of the algorithm on randomly generated instances are also presented.

Scheduling incoming and outgoing trucks at cross docking terminals to minimize the storage cost
Cross docking terminals allow companies to reduce storage and transportation costs in a supply chain. At these terminals, products of different types from incoming trucks are unloaded, sorted, and loaded to outgoing trucks for delivery. If the designated outgoing truck is not immediately available for some products, they are temporarily stocked in a small storage area available at the terminal....
متن کاملLocation-Allocation and Scheduling of Inbound and Outbound Trucks in Multiple Cross-Dockings Considering Breakdown Trucks
This paper studies multiple cross-dockings where the loads are transferred from origins (suppliers) to destinations (customers) through cross-docking facilities. Products are no longer stored in intermediate depots and incoming shipments are consolidated based on customer demands and immediately delivered to them to their destinations. In this paper, each cross-docking has a covering radius tha...

In order to reduce costs and increase efficiency of a supply chain system, cross docking is one of the most important strategies of warehousing for consolidation shipments from different suppliers to different customers. Products are collected from suppliers by inbound trucks and then moved to customers by outbound trucks through cross dock. Scheduling of trucks plays important role in the cros...

Nowadays, cross-docking is one of the main concepts in supply chain management in which products received to a distribution center by inbound trucks which are directly to lead into outbound trucks with a minimum handling and storage costs as the main cost of a cross-docking system. According to the literature, several metaheuristics and heuristics are attempted to solve this optimization model....
