Natural disasters worldwide have highlighted the need for special logistical treatment, called humanitarian logistics. It is known, however, that there are significant challenges in implementing systematized logistics processes, especially those related to the infrastructure and location of humanitarian assistance centers and coordination of emergency processes, including the location of temporary shelters. This paper proposes a hybrid approach of a mathematical multicriteria model based on utility theory and FITradeoff for portfolio problems to assist the management of emergency coping strategies for disaster risks caused by urban flooding. Focusing on the principles of humanitarian logistics for prioritizing the spatial location of temporary shelters. By addressing objectives that require a global and comprehensive view, the multicriteria methods are effective in risk management due to their main characteristic of recognizing subjectivity as an intrinsic part of decision problems. Therefore, four criteria were raised to evaluate the order of prioritization for the deployment of temporary emergency shelters. Therefore, complex situations such as flooding, which require contingency planning over large areas and managing logistical activities, are difficult and complex tasks. As a result, therefore, a subset of locations to be considered as community or collective temporary shelters was established, as well as the computational vision and the logistic operations mode needed to operate these shelters and save lives, which constitutes a helpful decision support tool regarding the selection and location of temporary shelters capable of assisting in the construction of the Emergency Plan in response to floods, at the strategic or operational level of logistical decisions.

“…However, it is sometimes necessary to consider the constraint of shelter capacity in evacuation management, especially in largescale evacuation scenarios. Recently, studies have analyzed the impacts of shelter capacities and their geographical distribution on evacuation outcomes (Alam et al, 2021;Khalilpourazari and Pasandideh, 2021;Oh et al, 2021;Liu and Lim, 2016). Future studies should consider more shelter properties to improve the current modeling framework.…”

“…City planners and policy makers need to identify safe areas outside of flood inundation region as feasible shelter locations for households who live in the at-risk areas. There have been some studies that explored the criteria of shelter location arrangement for evacuation planning (Alç ada-Almeida et al, 2009;Nappi and Souza, 2015;Bayram et al, 2015;Li et al, 2012;Alam et al, 2021). For instance, Bayram et al (2015) developed an optimization model to allocate evacuation sites and assign each evacuee to the nearest shelter, with the objective of minimizing the total evacuation time.…”

“…A limitation of this study is that evacuee's travel time is obtained from a simplified traffic model and the road network is not well represented in the network analysis. In a recent study, Alam et al (2021) used a massive traffic simulation model and a multiple criteria evaluation method to identify candidate evacuation shelters, taking into account of environmental conditions, structural attributes, emergency services and transportation aspects. However, this study focused on obtaining a suitability score for each candidate shelter site with various weighting factors, and failed to examine to what extent evacuation performance could be affected by the number of shelters and their geographical distribution in the community.…”

Abstract. In many flood-prone areas, it is essential for emergency responders to use advanced computer models to assess flood risk and develop informed flood evacuation plans. However, previous studies have limited understanding of how evacuation performances are affected by the arrangement of evacuation shelters regarding their number and geographical distribution and human behaviors regarding the heterogeneity of household evacuation preparation times and route searching strategies. In this study, we develop an integrated socio-hydrological modeling framework that couples (1) a hydrodynamic model for flood simulation, (2) an agent-based model for evacuation management policies and human behaviors, and (3) a transportation model for simulating household evacuation processes in a road network. We apply the model to the Xiong’an New Area and examine household evacuation outcomes under various shelter location plans and human behavior scenarios. The results show that household evacuation processes are significantly affected by the number and geographical distribution of evacuation shelters. Surprisingly, we find that establishing more shelters may not improve evacuation results if the shelters are not strategically located. We also find that low heterogeneity in evacuation preparation times can result in heavy traffic congestion and long evacuation clearance times. If each household selects their own shortest route without considering the effects of other evacuees’ route choices, traffic congestions will likely to occur, thereby reducing system-level evacuation performance. These results demonstrate the unique functionality of our model to support flood risk assessment and to advance our understanding of how the multiple management and behavioral factors jointly affect evacuation performances.

“…(A) The choice of evacuation routes and locations of evacuation points are traditional problems [41][42][43][44][45][46][47][48][49][50][51][52]. The evacuation time is often chosen as an efficiency criterion [42,44,[46][47][48][49], and the evacuation cost is an additional criterion [45,46,49].…”

The Problem of Effective Evacuation of the Population from Floodplains under Threat of Flooding: Algorithmic and Software Support with Shortage of Resources

Extreme flooding of the floodplains of large lowland rivers poses a danger to the population due to the vastness of the flooded areas. This requires the organization of safe evacuation in conditions of a shortage of temporary and transport resources due to significant differences in the moments of flooding of different spatial parts. We consider the case of a shortage of evacuation vehicles, in which the safe evacuation of the entire population to permanent evacuation points is impossible. Therefore, the evacuation is divided into two stages with the organization of temporary evacuation points on evacuation routes. Our goal is to develop a method for analyzing the minimum resource requirement for the safe evacuation of the population of floodplain territories based on a mathematical model of flood dynamics and minimizing the number of vehicles on a set of safe evacuation schedules. The core of the approach is a numerical hydrodynamic model in shallow water approximation. Modeling the hydrological regime of a real water body requires a multi-layer geoinformation model of the territory with layers of relief, channel structure, and social infrastructure. High-performance computing is performed on GPUs using CUDA. The optimization problem is a variant of the resource investment problem of scheduling theory with deadlines for completing work and is solved on the basis of a heuristic algorithm. We use the results of numerical simulation of floods for the Northern part of the Volga-Akhtuba floodplain to plot the dependence of the minimum number of vehicles that ensure the safe evacuation of the population. The minimum transport resources depend on the water discharge in the Volga river, the start of the evacuation, and the localization of temporary evacuation points. The developed algorithm constructs a set of safe evacuation schedules for the minimum allowable number of vehicles in various flood scenarios. The population evacuation schedules constructed for the Volga-Akhtuba floodplain can be used in practice for various vast river valleys.
