Algorithms incorporated in the DSS are based on a data-driven modeling approach and independent of physical parameters of the region, and hence the proposed DSS is applicable to any area. Based on predicted active cases, the demand of lower-level units and total availability, allocation, and lockdown decision is made. A MATLAB-based GUI is developed based on the proposed DSS and could be implemented by the local authority.

The framework is developed by considering the dynamics of Pandemic, hierarchical government structure, and non-uniformity of unit resource requirement among different units. The cost function is designed to minimize the difference between the demand, actual allocation, and ideal allocation, where ideal allocation for a region is considered based on the predicted active cases in a fraction of predicted total active cases of all regions. Different cost functions are used at a different level of organization based on the available information. The model can also accommodate severity of disaster in a region in this framework. A sample allocation case study is presented for the allocation of oxygen for different states of India.

This paper presents the possible application of UAVs at different stages of cyclone mitigation. The overall system architecture necessary for preparedness, rescue operation, resource allocation, and damage assessment using UAVs during cyclones is described. Although general commercial UAVs are reported to be used in cyclone operations, UAV systems should be planned specifically for cyclone operations to improve efficiency. Here, the specification required for effective and safe UAV operations in the post-cyclone scenario is presented. Mission planning required for various rescue, relief, and damage assessment missions related to cyclone management is discussed. A case study of deploying UAV in Amphan cyclone operation in West Bengal is also presented. This paper can help disaster management authorities to develop UAV systems specifically to cater to cyclone operations.

This paper has developed a multi-event crisis management system using a non-cooperative, complete information, strategic form game model. In the proposed system, each emergency event is assumed to occur in different locations simultaneously. These locations are represented as the players in the game, competing with the other players for an optimal allocation of scarce resources available at different resource stations. The players incur a non-monetary cost for obtaining resource units. The objective of the proposed game is to derive optimal strategies for an effective and fair allocation of resources to the respective players.

Outliers in the measurement can seriously degrade the estimation performance of conventional nonlinear filters. The proposed robust filter resists the effect of outliers to provide improved estimation. The square of Mahalanobis distance of innovation vector is taken as the judging index for robustness. Then the proposed robust algorithm has been evaluated with a benchmark problem of ballistic object tracking during re-entry phase. With the help of simulation, it is shown that when measurement outliers exist, the robust algorithm outperforms its conventional versions.
Allocation of limited resources in a fair manner is essential after a natural disaster, especiall... more Allocation of limited resources in a fair manner is essential after a natural disaster, especially if multiple emergencies occur at the same time. In this paper, a resource allocation methodology is proposed based on a two-player, non-cooperative, strategic form game where the crisis events, assumed to occur at different locations, are considered as the players. The objective is to obtain an optimal strategy for the individual players which leads to an effective allocation of an indivisible resource when the availability of the resource is insufficient to satisfy the need of all the players of the game. Each player incurs a cost for demanding resources based on a non-monetary cost function which is used to generate the game matrices. The cost function is formulated such that collective good and fair sharing are incentivised. It is shown that at least one pure strategy Nash equilibrium (PSNE) always exists for the formulated game. A desirable resource allocation strategy is obtained ...
