(2009). Batch picking of orders can yield higher productivity in high volume situations, but necessarily requires subsequent accumulation and sortation. Characteristics of a Warehouse: Following are the chief characteristics of an ideal warehouse: (i) Sufficient Space: Warehouse is a place used for the storage or accumulation of goods. According to Rushton et al. In addition, the support of multiple taxonomies is also critical for a data warehouse, and to the extent the architects have created a database architecture that will provide for metadata definition and re-defining of taxonomies is the extent to which the data warehouse will have greater use in the organization. Many such processes identified as, both sequential and progressive zoning can also be considered with or without batching (Gu et al. All previous reviews broadly focus on warehouse design and operational issues ignoring performance measures affecting each function of warehousing and overall productivity. induction process as bottleneck which governs syst. The purpose of this paper is to model such policy and develop an e-decision support system assisting enterprise practitioners with real-time decision making.

Also, the developed methodology incorporating features of e-DSS along with quantitative modeling is an inimitable research contribution justifying rational data support. Production Research 43, 17, pp.3561-3581. Five order picking policies, strict order, batch, sequential zone, batch zone, and wave, are evaluated using labor requirements, processing time, and customer service as performance measures. The objective is to investigate design issues from lean perspective, and the findings reveal the interrelationship between performance measures, solution approaches and wastes affecting leanness. performance’. VTT Technical Research Centre of Finland conducted a study on warehousing in 1999-2000. number of parts and the remaining load is stored again (De Koster et al. Design/methodology/approach: After forecasting static storage allocation between two planning horizons, if a particular SKU is less or non-moving, then it will cause SW, as the occupied location can be utilized by other competing SKUs, and also it impedes material flow for an instance. A simulation model was developed to investigate these picking policies in a mail order environment. (1995). paper also looks into how and what role can the technology place ensure the effectiveness and the safety of the warehouses. Also, many studies have been found solely for picking efficiency but the integrated, model including responsiveness may provide better results.
