“…Two accessibility problems were studied: The Road Network Accessibility Problem (RNAP) and The Work Troops Scheduling Problem (WSP) (Sakuraba et al, 2016a(Sakuraba et al, , 2016b). RNAP appears in emergencies and the idea is to identify paths quickly from starting points to target areas in the city.…”

Goal: Post-disaster operations are a challenging issue, which becomes very complex due to the high density of population in urban areas. Thus, efficient relief operations are very relevant in attenuating the impacts of disasters on the population. For this purpose, optimizing post disaster operations plays a key role, and such issues are focused on this contribution. Design / Methodology / Approach: Optimization problems appearing in the aftermath of disasters, related to accessibility, distribution and facility location are summarized. They were addressed using real data and the core of such problems was identified in a bottom-up approach, by analyzing the situation on the ground. Results: Examples of results are presented by means of maps with decision support information. A case study on an addressed location problem is described for the 2015 Kathmandu earthquake. In addition, new trends and opportunities are pointed out, taking into account technological tools, the endogenous characteristics of disasters and emerging applications. Limitations of the investigation: Regarding the Kathmandu case study, two issues are left for future studies: the uncertain data associated with the affected population and the elasticity of demands. Practical implications: The data treatment to produce inputs for the algorithms and suitable outputs for the relief teams highlight a collective effort and a real opportunity to use the results practically for humanitarian logistics. Originality / Value: The optimization models were progressively approached to the situation on the ground, which permits us to identify difficult aspects of the problems, while remaining pragmatic enough to solve real issues.

“…In the case of population density variable, the relationship is mostly negative except few areas in the far south, west and northern areas, which showed a positive relationship. The study of [6], focused on the Road Emergency Rehabilitation Problem, divided into the Road Network Accessibility Problem (RNAP) and the Work-troops Scheduling Problem (WSP). The first one consists in finding traversable paths for relief teams to reach the population, and the later generates a repairing schedule to improve access to refugee areas.…”

In this paper, urban traffic accessibility is regarded as the external manifestation of the dynamic process of the coupling of several traffic systems. Firstly, the relationship between a subway system, a bus rapid transit system, and a common bus system are analyzed, as well as the relationship between the traffic networks and the ground road network, and the coupling networks are constructed to objectively and comprehensively reflect the coordination structure of a city's traffic system. Then based on the static structure of the coupling traffic networks, dynamic process of vehicles and personnel flow is analyzed, and the networks' dynamic characteristics is studied to get a congestion propagation model, so as to provide the basis for quantitative evaluation for the accessibility of the multi-traffic system. Finally, an algorithm to solve the accessibility of the system is designed and the practical reachability of the traffic networks of a sample city is calculated.

Waste clean-up after a disaster is one of the most critical tasks in the response stage of disaster management. We develop a model to minimise the cost and duration of disaster waste clean-up considering using Temporary Disaster Waste Management Sites (TDWMSs), which can store and process waste before it is sent to the final disposal sites. The problem that arises can be seen as a Multi-Period Two-echelon Location Routing Problem (MP-2ELRP) in which the main decisions are the location of the TDWMSs and the routing of vehicles in both echelons. In this paper, we propose both a mixed-integer program and a Genetic Algorithm (GA) to model and solve the problem. Computational tests indicate: (i) the performance of proposed GA is robust; (ii) the use of TDWMSs can reduce both total waste clean-up cost and duration; and (iii) the capacities of TDWMSs have a significant impact on the total waste clean-up time and duration.
