This paper presents a scheduling problem that arises in an automatic storage/retrieval warehouse system AS/RS involving the scheduling of the stacker crane load operations. The loads are considered as jobs, the pallets of a load are seen as the job's operations. The forklifts are the machines. The optimization of sequence allows minimizing the idle time of the warehouse's equipments. A procedure based...
The optimization indices and constraints of flight pipeline planning was established, the method of extracting and clipping terrain was proposed, and the model of flight pipelines in two dimensions was established. By proposing the definition of density constraint, SAS was improved to DCSAS, and the complexity of DCSAS was analyzed. The simulation result proved that DCSAS, comparing with SAS, has...
Today's competitive business environment has resulted in increasing cooperation among individual enterprises as members of a supply chain. For the enterprise, how to integrate heterogeneous logistics-related software becomes a key challenge in the whole lifecycle of logistics processes. This paper presents such a framework called SCLPIF for supply logistics processes integration based on Web services...
