The inventory routing problem presented in this study is a one-to-many distribution network consisting of a manufacturer that produces multi products to be transported to many geographically dispersed customers. We consider a finite horizon where a fleet of capacitated homogeneous vehicles, housed at a depot/warehouse, transports products from the warehouse to meet the demand specified by the c...

This paper describes the technology of data warehouse in healthcare decision-making and tools for support of these technologies, which is used to cancer diseases. The healthcare executive managers and doctors needs information about and insight into the existing health data, so as to make decision more efficiently without interrupting the daily work of an On-Line Transaction Processing (OLTP) s...

A Data warehouse is a tool that is used by big companies, and it gathers data coming from different sources. The main goal of a data warehouse is not only to store data, but also to help companies to make decisions. The huge volume of data makes processing queries complex and time-consuming. In order to solve this problem, the materialization of views is suggested as a solution to improve the p...

We solve the uncapacitated warehouse location problem with a simple genetic algorithm and find a significant influence of the numbering of warehouses on the performance of the genetic algorithm. The effect is explained by linking a decomposition result for the problem to genetic algorithm theory, and its relevance is underlined by means of an empirical study based on over 600 widely used benchm...

In order to realize the intelligent management of a power materials warehouse, Internet Things based on wireless sensor networks (WSNs) is promising effective solution. Considering limited battery capacity nodes, optimization topology control and determination amount collected data are critical for prolonging survival time WSNs increasing satisfaction warehouse supplier. Therefore, in this pape...

In Data Warehousing, Extraction-Transformation-Loading (ETL) are the key tasks that are responsible for the extraction of data from several sources, their cleansing, customization and insertion into data warehouse [10]. More specifically ETL tools are category of specialized tools with the task of dealing with data warehouse cleaning and loading problems. These task are very critical in every d...

Assigning products to and retrieving them from proper storage locations are crucial in minimizing the operating cost of a unit-load warehouse. The problem becomes intractable when the warehouse faces variable supply and uncertain demand in a multi-period setting. We assume a factor-based demand model in which demand for each product in each period is affinely dependent on some uncertain factors...

This study is an extension of the Joint Replenishment Problem (JRP) that takes into accounts warehouse-space restrictions. The focus of this study is to determine the lot size of each product under power-of-two policy to minimize the total cost per unit time and to generate a feasible replenishment schedule of multiple products without exceeding the available warehouse-space. In order to solve ...

Assigning products to and retrieving them from proper storage locations in a unit-load warehouse are crucial in minimizing its operating cost. The problem becomes intractable when the warehouse faces uncertain demand in a dynamic setting. We assume a factor-based demand model in which demand for each product in each period is affinely dependent on some uncertain factors. The distributions of th...

There exist a number of mathematical problems in the literature concerning warehouse storage optimization. However, to the best of our knowledge the problem of finding optimal slot sizes in pallet rack system minimizing the occupied storage space is not studied. More precisely, the problem is to optimally choose k ofm pallet racks with pallets in a warehouse, find optimal slot sizes in pallet r...
