Various disasters with serious results are reported and happen around our lives. Most of them are unconventional contingency events. Emergency relief is an important activity dealing with the disasters to transfer a large number of materials to the destroyed places for casualties and reconstruction for the country, even the world. Container multimodal transportation will play an important role ...
Relief representation is a difficult problem. The surface of the Earth cannot be defined by a physical or mathematical representation but can be approximated by digital elevation models (DEM), triangular irregular networks (TIN), and contour lines. Each representation carries approximation errors. A DEM introduces the greatest errors because we assume that the surface of the Earth can be approx...
INTRODUCTION: Despite the fact that natural disasters are on the rise in Iran, no study has yet explained the performance indicators in the relief supply chain in crisis situations. Creative leadership in the relief supply chain can be of great help to the enhancement of internal strengths, provision of creative solutions to potential threats, and maintenance and promotion of public health. The...
Accidents and natural disasters and crises coming out of them indicate the importance of an integrated planning to reduce their effected. Therefore, disaster relief logistics is one of the main activities in disaster management. In this paper, we study the response phase of the disaster management cycle and a bi-objective model has been developed for relief chain logistic in uncertainty conditi...
results responsiveness, effectiveness, and flexibility with eigenvalue of 2.628 were identified as the main aspects of agility in humanitarian health supply chains. the components of visibility, reactivity, and speed were identified as components of responsiveness. quality, reliability, and completeness were identified as components of effectiveness. volume, delivery, mix, and product were know...
occurrence of natural disaster inflicts irreparable injuries and symptoms on humans. in such conditions, affected people are waiting for medical services and relief commodities. thus, quick reaction of medical services and relief commodities supply play important roles in improving natural disaster management. in this paper, a multi-objective non-linear credibility-based fuzzy mathematical prog...
Abstract: In this paper, we develop a mean-variance disaster relief supply chain network model with stochastic link costs and time targets for delivery of the relief supplies at the demand points, under demand uncertainty. The humanitarian organization seeks to minimize its expected total operational costs and the total risk in operations with an individual weight assigned to its valuation of t...
in this thesis protic and aprotic ammonium-based ionic liquids were synthesized and their surface tensions were measured in the range of 298-373k. the protics are alkyl ammonium-based ils with the carboxylate (formate, acetate, propionate) anion and aprotics are quaternary ammonium-based ils with bis(trifluoromethylsulfonyl)imide anion. capillary rise method was used for surface tension measure...
Supply chain disruption risk usually poses a serious challenge to the management of emergency supplies procurement between government and enterprises in cooperation. To research impact supply on demand sides for disaster relief, model based quantity flexibility contract is constructed. The introduces stockout measure degree uses per unit material relief value quantify benefits. Further, it anal...
