Abstract Multi-model DBMSs, which support different data models with a fully integrated backend, have been shown to be beneficial warehouses and OLAP systems. Indeed, they can store according the multidimensional model and, at same time, let each of its elements represented through most appropriate model. An open challenge in this context is lack methods for logical design. multi-model context,...

The supply chain network consists of suppliers, warehouses, distribution centers, and retail outlets which provide the flow of material and products. Determining the location of the facilities and warehouses, determining the appropriate number of warehouses, determining which products will be received by which customers and determining the size of each warehouse are strategic decisions. Due the...

The traditional, uncapacitated facility location problem (UFLP) seeks to determine a set of warehouses to open such that all retail stores are serviced by a warehouse and the sum of the fixed costs of opening and operating the warehouses and the variable costs of supplying the retail stores from the opened warehouses is minimized. In this paper, we discuss the partial coverage uncapacitated fac...

In this paper we impose a capacity restriction on a multi-echelon joint location-inventory model. The setting is that of a single product manufacturer distributing its product to a number of warehouses, each of which is assigned to a number of retailers. There is no lateral supply between warehouses and they do not share retailers. The model simultaneously makes decisions on location and invent...

In this article we present an interesting result on consolidating several one-warehouse multiretailer systems with deterministic customer demands. We examine the inventory cost impact of decreasing the number of warehouses used (by possibly re-assigning retailers to other warehouses). We prove that (i) using only two properly selected warehouses, we can ensure that the system-wide inventory cos...

This paper proposes an enterprise modeling framework for the deployment of data warehouses. The framework provides the information roadmap coordinating source data and different data warehouses across the business enterprise. The paper introduces a solution to address data warehousing issues at the enterprise level while avoiding the pitfalls of creating enterprise data warehouses and universal...
