multi-echelon inventory systems are one of the most important and attractive areas in modelling supply chain management so that several researches and studies have been done about. in this paper, the total cost function of a two-echelon inventory system with central warehouse and many identical retailers controlled by continuous review inventory policy is estimated. we have assumed the demand i...

Abstract: So far, too little attention has been paid to total burden of healthcare associated infections (HAIs) in Iran. In present study, we aimed to assess the rate of HAIs, as well as economic burden of hospitalization and antibiotic related cost associated with HAIs at training Taleghani hospital in Iran and to compare our results with NNIS system. This research to date for the first time h...

Abstract Time and cost estimation of tunneling projects is usually performed in a deterministic manner. However, because the approach not capable dealing with uncertainty, probabilistic methods have been developed over years to better account for this problem. Three models type are Decision Aids Tunneling (DAT) two at KTH Royal Institute Technology Czech Technical University Prague. To conduct ...

An important factor in sustainable agriculture and economic management is to calculate areas under different crops that the inputs of agriculture connect to this topic. Planning of agricultural mechanization, fertilizer and pesticide requirements, pests and diseases control, estimates of agricultural production, income and tax and financial planning, all linked to the cultivated areas and estim...

  These days, data mining one of the most significant issues. One field data mining is a mixture of computer science and statistics which is considerably limited due to increase in digital data and growth of computational power of computer. One of the domains of data mining is the software cost estimation category. In this article, classifying techniques of learning algorithm of machine ...

a design discharge is an important issue in the design process of pressurized irrigation networks. underestimating the desing discharge affect, the required pressure and offtake discharge, increase the cost of the network. because of the lack of a standard and reliable method for this propuse, usually different approches are used by designers. the network fails to provide the required flow rate...
