The effective prevention and response of public emergencies such as natural disasters is not only a difficult problem for China, but also that governments all over the world hope to be solved effectively. Emergency supply chain management very important disaster relief. It determines whether emergency work can carried out efficiently orderly, which major event affecting national economy people’...

In this paper, a newsboy model is developed under uniformly distributed lead-time and demand that is an appropriate assumption in obtaining optimal relief inventory of humanitarian disasters. It is noteworthy that limited historical data are in hand on relief operations. Hence, analytical and approximate solutions for optimal relief order quan­tity were derived. The effect of lead-time uncertai...

the aim of this study was to represent effective componentsin demand chain which help organizations attain high performance levelsthrough identification of these components and determining theirdegree of importance. the following questions were major ideas of thisstudy: what are the most effective components in demand chain? andhow are they effective on organizational performance? to this end,m...

microstructural evolutions of twinning induced plasticity (twip) steel during tensile straining wereinvestigated by in situ sem observations. the results indicated that slip lines and mechanical twins aswell as surface relief were increased with increasing strain, resulting in a stepped surface. additionally,these deformation mechanisms could change the shape of each grain via shear and rotatio...

Objective - The purpose of this paper is to find out the key research direction and disaster relief optimization method governments organizations at all levels in Guangxi deal with tropical cyclone disasters. Methodology/Technique In terms methods, most results focus on qualitative emergency logistics, quantitative are relatively few, but there many kinds calculation methods. focus, methods sup...

We consider a capacitated multi-stage operations scheduling problem encountered in a real life supply chain for disaster relief, consisting of component suppliers, a packaging contractor, local distribution centers, and many customer demand points. Each customer order has a due date and can be fulfilled by either existing inventory at distribution centers or a new assembly operation at the pack...
