Introduction Warehouses are important components of most supply chains. In terms of cost, they represent approximately 20% of total logistics costs (ELA/AT Kearney, 2004 and Establish/Davis, 2005), whilst in terms of service they are critical to the achievement of customer service levels (Frazelle, 2001), particularly as distribution centres are often the final point in the supply chain for ord...

This paper derives exact expressions for the Laplace-Stieltjes transform of order picking time in single- and 2-block warehouses. We consider manual warehouses that deploy return routing assume sizes follow a Poisson distribution. The results this apply to wide range storage policies, including but not restricted class-based random storage. Furthermore, we compare performance policies warehouse...

The supply chain of a manufacturing enterprise is a world-wide network of suppliers, factories, warehouses, distribution centres and retailers through which raw materials are acquired, transformed and delivered to customers. Supply chain management is the strategic, tactical and operational level decision making that optimizes supply chain performance. The strategic level defines the supply cha...

In the strategic design of a distribution system, the right number of stock points for the various products is an important question. In the last decade, a strong trend in the consumer goods industry led to centralizing the inventory in a single echelon consisting of a few parallel warehouses or even a single distribution center for a Europe-wide distribution system. Centralizing inventory is j...

The Supply Chain (SC) of both manufacturing and commercial enterprises comprises a highly distributed environment, in which complex processes evolve within a network of interacting companies. A typical SC includes different levels as shown in the diagram of Figure 1. As shown in this figure, and reading the diagram from right to left (“Customer Information Flow”), the first level of organizatio...

Supply chain management is a set of used methods for the efficient integration of suppliers, manufacturers, warehouses, and sellers to response customer requirements to reduce system costs and to distribute products at the right place and right time. This study aims to identify and rank the supply chain damages using the analytic network process as a practical case in a fast moving consumer goo...

Hash based search has, proven excellence on large data warehouses stored in column store. Data distribution has significant impact on hash based search. To reduce impact of data distribution, we have proposed Memory Managed Hash (MMH) algorithm that uses shift XOR group for Queries and Transactions in column store. Our experiments show that MMH improves read and write throughput by 22% for TPC-...
