Rainwater harvesting (RWH) may be an effective alternative water supply solution in regions affected by water scarcity. It has recently become a particularly important option in arid and semi-arid areas (like Mediterranean basins), mostly because of its many benefits and affordable costs. This study provides an analysis of the reliability of using a rainwater harvesting system to supply water f...
The blood supply chain as a part of healthcare systems play a substantial role in health improvement within societies, and blood supply for daily needs and especially in disasters is the challenges requiring more attention. This paper presents a fuzzy-stochastic mixed integer linear programming model to design blood supply chain network for disaster relief. To deal with the uncertainty in model...
Reverse supply chain is a process dealing with the backward flows of used/damaged products or materials. Reverse supply chain includes activities such as collection, inspection, reprocess, disposal and redistribution. A well-organized reverse supply chain can provide important advantages such as economic and environmental ones. In this study, we propose a general framework and formulate a m...
Due to the many risks involved in the supply chain, and the high costs associated with damage to the supply chain, risk identification and evaluation should be a top priority in risk management programs in organizations. Risk assessment and ratings determine the superiority of each risk based on the relevant indicators and thus provide an appropriate response to each risk. In this regard, this ...
abstract in order to evaluate crop water stress index (cwsi) and canopy temperature of wheat cultivars under terminal drought stress, a field experiment was conducted at the agricultural research station of shiraz university, shiraz, during 2009 growing season. five wheat cultivars including shiraz, bahar, pishtaz, sistan and yavaros and four levels of water regime including well watering [irr...
background: corrosivity is one of the factors affecting the water quality. not controlling the chemical quality of water in the distribution network causes corrosion, sedimentation and economical and health damages. the aim of this study was to determine the drinking water corrosivity and sediment of kuhdasht, iran by using the corrosivity index. methods: in this study, 12 predetermined areas l...
In recent years, the green supply chain has become a key strategy for the competitiveness of organizations, where the reverse and closed-loop supply chains are one way to achieve it. In the current competitive environment, the closed-loop supply chain helps reduce costs by re-using recyclables and reducing environmental pollution by reducing waste and extending product life. In this study, a cl...
Rainwater harvesting is effectively mandated in several urban areas of New Zealand. To understand the costs and benefits of rainwater harvesting from an end-user perspective, semistructured interviews were conducted with 14 homeowners in northern Auckland affected by these regulations. Residents report differences in four aspects of urban rainwater infrastructure - security of supply, water qua...
