Optimization of Storage Location Assignment for Fixed Rack Systems
2010A multi-objective mathematical model and an improved Genetic Algorithm (GA) are formulated for storage location assignment of the fixed rack system. According to the assignment rules, the optimization aim is to maximize the storage/retrieval efficiency and to keep the stability of the rack system.

A Storage Assignment Model for Batch Preparation in Process Industries
SSRN Electronic Journal, 2010PurposeThe purpose of this paper is to develop new model formulation for reducing the workload in pre‐batching at a manufacturer of flavors and fragrances, by optimally assigning ingredients to different storage types, taking into account past usage of ingredients and several restrictions about volumes and number of storage units.Design/methodology ...

Storage location assignment and interleaving policy are two closely related problems in warehousing management. This paper addresses the location assignment and interleaving problem at the same time in an automated storage/retrieval system with duration-of-stay based shared storage policy.

A Balance Storage Nodes Assignment for Wireless Sensor Networks
2013A balance storage nodes assignment problem is proposed for wireless sensor networks in order to save history data as much as possible when the network cannot connect to the sink node(s). Its aim is to assign storage nodes as evenly as possible to each source node, while it can minimize the storage path cost of the whole network.

In existing AS/RS research, storage assignment policies are evaluated based on the probability that item type j will be stored (and subsequently retrieved). This note applies the turnover-based and class-based assignment policies of Hausman et al. (1976) to a stochastic environment by identifying the kth pallet of item type j: Frequently demanded ...

Safety storage assignment in as/rs
2013Picking time reduction has been the traditional perspective for warehouse optimization. When structural safety is considered, optimization of warehouse operations should be read even in terms of load mass distribution. In many practical cases the static safety of the system is related to mass distribution and barycenter highness, for example when a ...

On storage assignment policies for unit-load automated storage and retrieval systems
International Journal of Production Research, 2011This paper focuses on the management of automated storage and retrieval systems (AS/RS) from a practical standpoint. Most of the articles in the recent AS/RS literature rely on analytical models that are based on tight assumptions. However, some of these assumptions are not clear cut and therefore the validity of the results reported in the theoretical

Warehouse Storage Assignment by Genetic Algorithm with Multi-objectives
2019The proper assignment of storages to stocks prior to their picking is critical to reduce order picking costs. Appropriate storage assignments can also shorten storing time, improve storage utilization, and facilitate inventory management. Three objectives are considered: minimizing the routing length of storing stocks, maximizing the future chance of ...

A storage assignment policy in a man-on-board automated storage/retrieval system
International Journal of Production Research, 1992This paper deals with a man-on-board automated storage/retrieval system where each customer order consists of a number of different items and is picked one at a time. For the system the problem examined is to allocate storage locations dedicatedly to items so that the total travel time required to pick all the given orders per period is minimized.

Sustainable storage assignment in AS/RSs
2010Picking time reduction has been the traditional perspective for warehouse optimisation. When sustainability is considered, optimisation of warehouse operations should be read in terms of energy efficiency other than response time. In an AS/RS it can be imagined to associate to each location in a rack the value of energy consumed by the crane to reach ...
