Its effectiveness relies on the proper allocation of each kind of relief good amongst the demand areas on a given frequency. Because these operations involve a limited supply of relief goods, vehicles, and time, it is important to optimize these operations to satisfy as much demand as possible. The study aims to create a linear programming model which provides a set of recommendations on how the current disaster relief supply chain may be carried out, specifically on how distribution operations allocate supplies among demand nodes as well as the routes taken in a day. The areas visited per day would depend on the capacity of the vehicle fleet as well as on the routes that can be used. This linear programming model will use Balcik’s last mile distribution model, while modifying it for the relief operations in the Philippines. The model minimizes routing costs as well as penalty costs for unsatisfied demands. Map data is used for determining routes and historical data from previous disasters are used to determine the supply and demand for relief goods while providing a benchmark for results. The model produces recommendations for (1) Demand node schedule, (2) Best route for schedule, (3) Relief good allocation, and (4) Operational costs. It also provides the computational backbone for relief distribution decisions in the Philippines, allowing for more optimal operations in the future.</p></div>","PeriodicalId":20470,"journal":{"name":"Procedia Engineering","volume":"212 ","pages":"Pages 133-140"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.proeng.2018.01.018","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86251863","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Introducing the concept of equivalent routes, the scheme of the best route for evacuee at each location is the one along with the shortest time and minimal risk and suggested based on the Dijkstra algorithm.

Based on a household survey, conducted ten months after the 2015 South Indian floods in two affected constituencies (Mylapore and Velachery) of Chennai, residents were asked how long they took to recover from the floods and whether they took actively part in the recovery process. The results highlight that residents from the more affected constituency (Velachery) took significantly longer to restore physical aspects (e.g. energy, water, roads, etc.), but only partially longer for social and economic aspects. Aspects of social capital (leadership, communication, ownership and trust) were rated equally low in both communities. However, individual actions to help others or participate in volunteer groups increased more significantly in the constituency that was more affected. The findings from this case study point-out that flood disaster events trigger residents to become more solidary and active to help others, but have little impact on triggering a more active interplay between communities and authorities. This highlights that flood disaster events do not change inherent structural and institutional relationships between key actors (local government, communities, private sector, academia and NGOs) involved in disaster recovery processes.</p></div>","PeriodicalId":20470,"journal":{"name":"Procedia Engineering","volume":"212 ","pages":"Pages 643-650"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.proeng.2018.01.083","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88559700","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
