Optimizing the Storage Assignment in a Warehouse Served by Milkrun Logistics
نویسنده
چکیده
We investigate the problem of storage assignment in a warehouse served by milkrun logistics, i.e. vehicles circulating according to a pre-defined schedule between the warehouse and the production facilities of the plant. Such a logistic system results in an easy-to-characterize correlation among the request probabilities of the items in the warehouse. A MIP model is proposed that exploits this correlation for finding a class-based storage policy that minimizes the order cycle time or the average picking effort. Computational experiments show that our approach can achieve an up to 36-38% improvement in either criterion compared to the classical COI-based strategy.

Optimizing the Rearrangement Process in a Dedicated Warehouse
Determining the optimal storage assignment for products in a dedicated warehouse has been addressed extensively in the Facility Logistics literature. However, the process of implementing a particular storage assignment given the current location of products has not received much attention in the existing literature. Typically, warehouses use downtime or overtime to remove products from their cu...
متن کاملHybrid Optimization Methods for Warehouse Logistics and the Reconstruction of Destroyed Paper Documents
Themain topic of this thesis is the solving of real-world combinatorial optimization problems from two domains: storage location assignments and picking tour computations in warehouse management as well as the reconstruction of destructed paper documents from the field of forensics. Although from the application point of view these two topics have not much in common, parallels can be identified...

The required storage space and the material handing cost in a warehouse hinge on the storage implementation decision. Effects of storage area reduction on order picking and storage space cost are incorporated. Moreover, merchandises which are in the same shape and can be stored beside each other easily or goods that don't cause any danger like causing a fire if be in touch with each other, ...

متن کاملPRODUCTION INVENTORY MODEL FOR DETERIORATING ITEMS WITH SHORTAGES AND SALVAGE VALUE UNDER REVERSE LOGISTICS
In this paper, a production inventory model is developed for the business enterprise which consists of three wings. The first wing is for manufacturing new items, the second wing is for collecting the returned items, while third wing is for remanufacturing the returned item. In this model we consider the fact that the storage item is deteriorated during storage periods and salvage value is inco...
