This paper is concerned with a dynamic inventory control system described by network model where the nodes are warehouses and arcs represent production distribution activities. We assume that an uncertain demand may take any value in assigned interval we allow disturbed noise inputs. These assumptions yield mix of stochastic uncertainties. use method predictive to derive strategy. To deal uncer...

Paper aims The objectives of this paper are: (i) to analyze the impacts Inventory Record Inaccuracy (IRI) on picking productivity (PP), lost sales (LS), and warehouse capacity utilization (WCU) for different warehouses; (ii) verify if Cycle Counting (CC) implementation is sufficient reduce IRI (iii) number CC operators maintain performance. Originality A causal loop diagram in detail variable's...

This paper is interested in a food industrial group which produces large quantities of sugar and distributes it to warehouses and customers. The group should review its distribution policy, in particular, to optimize transportation costs and reduce losses caused by the current organization. In this paper, we propose an integer linear model to optimize the travel of full loaded trucks taking int...

This paper proposes a knowledge-based model to support spatial and temporal analysis of complex networks in data warehouses. The proposed model, inspired from geography, represents the dynamics of spatial elements in the network. Ontologies, describing element classes from a domain, space partitions, and time periods, respectively, help to define dimensions of data marts customized for specific...

A manufacturing supply chain is a network of suppliers, factories, subcontractors, warehouses, distribution centers and retailers, through which raw materials are acquired, transformed, produced and delivered to the end customers. Many methods have been suggested over the years for supply chain evaluation of any organization. This study discusses the supply chain performance criteria for effici...

Web data warehouses are useful for applications that need to process large amounts of Web data in a short time. This paper presents Versus, a Web repository model supporting object versioning and distributed operation for this kind of applications. Versioning allows applications to save the time dimension of data, enabling the development of new Web applications. Distribution allows parallel op...

OBJECTIVE The aim of our study was to investigate the species and breeding density of acaroid mites in stored products in China. METHODS We tentatively harvested the samples from the products stored in warehouses, commercial stores and civilian houses, and the products. RESULTS The results suggested the mites varied a lot in species regarding their ecological habitus and habitat. Still, the...

In a data warehousing environment, aggregate views are often materialized in order to speed up aggregate queries of online analytical processing (OLAP). Due to the increasing size of data warehouses, it is often infeasible to materialize all views. View selection, the task of selecting a subset of views to materialize based on updates and expectations of the query load, is an important and chal...

Consider a distribution system consisting of a set of retailers facing a single-period price-dependent demand of a single product. By taking advantage of the risk-pooling effect and the quantity/volume discount provided by suppliers or thirdparty carriers, the retailers may place joint orders and keep inventory at central warehouses before demand realization, and allocate inventory among themse...
