Data warehouses have traditionally been used to analyse large multidimensional datasets and provide enterprise decision support. With an increased availability of spatial data in recent years, several new strategies have been proposed to enable their integration into data warehouses and OLAP systems and perform complex analysis on them. One strategy to achieve this is to integrate existing Geog...

Recently, there has been an increasing interest in applying association rule mining on data warehouses to identify trends and patterns that exist in the historical data present in large data warehouses. These warehouses have a complex underlying multidimensional structure and the application of traditional rule mining algorithms becomes hard. In this paper, we review and critically evaluate the...

In this paper, a realistic replenishment model with multiple warehouses (one is primary warehouse (PW) from where the items are sold and others are secondary warehouses (SWs) where the items are stored) is developed with fuzzy lead-time under the assumption that the capacities of the warehouses are finite. Inflation and time value of money are taken into account. The items of secondary warehous...

How globalization and international trade affect sustainable development and environment has attracted worldwide attention. Associated with the import and export of primary commodities, ecologically important materials have been exchanged among regions and countries. China, having the largest population in the world and the highest economic growth rate in last decades, may have an important inf...
