An emergency logistics model based on Location-routing Problem (LRP) is proposed in this paper, and a two-phase heuristic algorithm is used to solve the model. It uses the minimization envelopment analysis method to solve the LRP in the emergency supplies center, and then calculates K shorter paths by the application of the nearest neighbor method. Considering the indexes of time, security, economic...
Given the condition of multi-demand sites, multi-variety emergency materials and roads with forbidden time window, the mathematic model and simulation model based on NCL are set up, and heuristic arithmetic based on POEM is designed in the paper. At last, the model and heuristic arithmetic are validated by an example and the satisfying result is gained.
When emergency occurs, a reasonable and efficient resource scheduling system is urgently needed to deal with influences caused by emergency. In regard to the scheduling problem of single one-time consumption resources in the emergency logistics system, this paper establishes a resource response decision model with the goal of minimum emergency response time, least saving points, highest reliability...
Applying the concept of integrated supply chain to emergency logistics, can effectively improve the operation efficiency of emergency logistics, shorten the supply time of emergency resource and diminish the disaster loss. From the view of integrated supply chain, this paper built an emergency logistics system model of Wuhan City Cluster and explored the countermeasures of constructing emergency logistics...
Large-scale emergency events bring a lot of effect to people's ordinary life, so it is necessary to provide fast and effective location-allocation analysis information for emergency traffic evacuation and succor. In this issue, some related models based on location-allocation analysis are introduced into emergency traffic evacuation field. Considering the actual situation and character of emergency...
The emergent resources can be served immediately is the most important task for the rescue mission. But it is too late to plan a path from supply points to the breakout point, when the emergency is happened. This article proposes a beforehand optimal model which solves the path selection problem before the outbreak of emergency, and the algorithm for emergency resource scheduling is given in this...
Various disasters with serious results are reported and happen around our lives. Most of them are unconventional contingency events that are difficult to be detected and discriminated. Emergency management is an important activity dealing with the contingent events. For the uncertainty, imperfect, stochastic, fuzzy and disturbed environments and the unrecognized characteristics of the events, it is...
With the continuous economic and social development, unconventional social emergencies constantly occur in China. However, there is a lack of in-depth scientific understanding for emergency resource allocation and scheduling under such unexpected situations. In this article, firstly, a grey-prediction-based emergency resource allocation model is proposed according to the reality and problems of current...
The goal of emergency rescue is to reduce casualties and property losses caused by unexpected events. How to improve emergency response speed is one of the most difficult problems in the area of emergency logistics. Therefore, the study of the optimal path selection problem for transport vehicles to improve emergency response speed is full of practical significance. In this paper, a multi-objective...
In order to improve the material supply capacity and the time efficiency of emergency relief system when bio-terrorism attacks happen, combining with the laws of dangerous source diffusion and considering the coordination relationship between national and city level repository of rescue network with supply base preparation system, this paper studied the problem of optimal model of emergency relief...
In the event of disasters such as hurricanes, earthquakes and terrorism, emergency relief supplies need be distributed to disaster victims in timely manner to protect the health and lives of the victims. We develop a modeling framework for disaster response where the supply chain of relief supplies and distribution operations are simulated, and analytics for the optimal transportation of relief supplies...
Emergencies have been bringing huge damage, even worse when emergency event chain reaction is formed. Different emergency evolution models have been studied in the systematic perspective to find out common characters and correlation among four various emergency events. We propose an academic framework with four hierarchies including single event, event chain, event network, and event supernetwork...
Timeliness is one of the most important objectives that reflect the quality of emergency rescue. To provide timeliness, the most obvious way is to increase the number of service facility available. Unfortunately, increasing the number of facility is generally impossible due to capital constraints. In such a case, the strategy for emergency facility location becomes a crucial issue. This artic discusses...
The existing literature mostly studies the allocation of emergency commodities in the emergency service center. This paper studies how to rationally distribute the scare emergency commodities between every factory when there aren't enough emergency commodities and related factories have to be mobilized to produce commodities after the large-scale emergency occurs. A mathematical model is established...
This paper describes the simulation modeling for planning for the efficient transportation of patients following an earthquake disaster. Research was performed in an effort to predict the consequences of conceivable scenarios. Discrete-event simulation modeling provided an effective supplement to disaster response procedures when simultaneously interface with and drive both planning systems and training...

With the threat of global bioterrorism, it is necessary to establish a scientific and reasonable system of emergency rescue supplies reserves and distribution, which can be benefit to form an effective emergency logistics network, to shorten the radius of emergency rescue. In the anti-bioterrorism system, a system of emergency service in a supply chain can be formed from the reserve and distribution...
