Tribolium confusum is one of the most common pests many commodities, especially cereals and their products. These are known for being destructive insect attacking infesting stored flour grain in soil, warehouses, grocery stores, homes. Therefore, this study aims to control these with an environmentally friendly, healthier, cost-effective pesticide instead artificial chemicals practice current m...

Due to the depletion of the fossil fuels and major concerns about the security of energy in the future to produce fuels, the importance of utilizing the renewable energies is distinguished. Nowadays there has been a growing interest for biofuels. Thus, this paper reveals a general optimization model which enables the selection of preprocessing centers for the biomass, biofuel plants, and wareho...

abstract in this paper an attempt is made to determine the most suitable agricultural commodities to be adopted for establishing a futures market in iran. two different approaches are adopted: the first involves identifying factors that contribute significantly to the success or failure of existing agricultural commodities futures contracts in established futures markets. the second involves si...

These last years, the sources of data became very heterogeneous and massive. The term "big data" is born to indicate this phenomenon. Unfortunately, he becomes difficult to manage big data to power the decisional system, and also it increases the time of interrogation of data from data warehouses. Several research works focused recently, on the proposal for the architectures of data warehouses ...

The effort of data mining, especially in relation to association rules in real world business applications, is significantly important. Recently, association rules algorithms have been developed to cope with multidimensional data. In this paper we are concerned with mining association rules in data warehouses by focusing on its measurement of summarized data. We propose two algorithms: HAvg and...

This paper proposes the macro model and micro model for the efficiency evaluation of data warehouses (DWH), and introduces Fuzzy Data Envelopment Analysis (FDEA) and Data Envelopment Analysis (DEA) to comprehensively assess DWH efficiency. FDEA can determine the efficiencies of data warehouses with multiple input / output variables, and also resolve the problem that standard DEA cannot handle w...

We studied a logistics network design model composed of plants, warehouses and customers. For designing this integrated model, we had to make two decisions simultaneously; the location of plants and warehouses, and the product distribution from plants to customers through warehouses. We provided a heuristic using the genetic algorithm. The chromosome presents the location of plants and the allo...

This study considers a supply chain that consists of n retailers, each of them facing a newsvendor problem, m warehouses and a supplier. The retailers are supplied with a single product via some warehouses. In these warehouses, the ordered amounts of goods of these retailers become available after some lead time. At the time that the goods arrive at the warehouses, demand realizations are known...

with the eight sassanians reliefs, naghsh-e rustam in marvdasht is a prominent complex safeguarding a complete collection of the sassanian period. seven of these reliefs have been repeatedly the subject of investigations thanks to their relatively better conditions. the fifth relief, however, has not yet been studied due to their damaged status. it depicts the full-face portrait of a sassanid k...
