<span>Ammonium nitrate (AN, NH4NO3) is one of the materials used in chemical industry and agriculture. AN not considered a fire risk but it strong oxidizing agent that can lead to explosion, so, ammonium must be stored under specific environmental conditions avoid occurrence dangerous situations. In this paper, smart monitoring system for Ammonium storage developed. The consists three-par...

In an e-retailing setting, the efficient utilization of inventory, storage space, and labor is paramount to achieving high levels of customer service and company profits. To optimize the storage space and labor, a retailer will split the warehouse into two storage regions with different densities. One region is for picking customer orders and the other to hold reserve stock. As a consequence, t...

The distribution warehouse is located between manufacturers and customers. Storage facilities are designed around four primary functions: holding, consolidation, break-bulk, and mixing. In addition, materials handling within a storage-handling system reduces to three primary activities: loading and unloading, movement to and from storage, and order filling. Generally, it is more difficult to bu...

For developing data warehouse (DW) and OnLine Analytical Processing (OLAP) systems, the dominant relational database reaches its limitations. On the way of the development, object-relational (O-R) database is preferred to get over those ones. This paper introduces metadata for data warehouse system on O-R database and specifies new kind of metadata for mapping from object-oriented environment t...

This paper presents a new formulation for warehouse inventory management in a stochastic situation. The primary source of this formulation is derived from FP model, which has been proposed by Fletcher and Ponnambalam for reservoir management. The new proposed mathematical model is based on the first and the second moments of storage as a stochastic variable. Using this model, the expected value...

This study addressed warehouse storage location assignment problems (SLAP) to minimize total travelling distances in an order-picking process. The problem was formulated and presented as a mixed integer programming model. The LINGO optimization solver was then used to find solutions for a set of generated problems. The results showed that the LINGO optimization solver easily attained optimal so...

In this paper, we apply continuous review (S-1, S) policy for inventory control in a three-echelon supply chain (SC) including r identical retailers, a central warehouse with limited storage space, and two independent manufacturing plants which offer two kinds of product to the customer. The warehouse of the model follows (M/M/1) queue model where customer demands follow a Poisson probabilit...

A common rule for retrieval from Automated Storage and Retrieval Systems (AS/RS) is to follow a first-in-first-out (FIFO) discipline. In many cases FIFO priority is set by date of manufacture. In some cases, however, the material may be stored in the warehouse according to a FIFO priority which depends on something other than the date of manufacture of that material, such as rules based on ship...

This paper tries to provide a new view on the currently vastly discussed and successfully employed concept of a Data Warehouse. This view presents it in the light of Knowledge Management, i.e. a Data Warehouse can serve as a storage medium for keeping the corporate memory, or at least concerning certain types of data. It helps gaining new knowledge by delivering well integrated data to analysis...
