Emergency and terminated evacuation of warehouse by dijkstra's algorithm

Abstract

One of the most important services that developing technology has brought to humanity and that serves as a facilitator in daily life has been navigation services. Thanks to location services, millions of people can easily reach the point they want to reach in daily life, and their industrial impact has also become an indisputable advantage. In addition to location information obtained through GNSS, technological developments now support location-based data and information production in indoor spaces. Here too, it is noticeable that indoor navigation maps are increasingly covering a wider area as it is getting closer to the present day. Indoor navigation maps are taking firm steps towards becoming one of the most effective facilitators that the internet age has brought to humanity. In this progression, its main areas of use stand out in megastructures such as shopping malls, university campuses, business campuses, museums, multi-storey buildings, warehouses, which accommodate many places and people that serve more than one purpose. Today, thanks to the widespread use of IoT and ease of use by the end user, indoor navigation solutions have gained an important place, especially in all kinds of loading and unloading scenarios of warehouses. However, earthquake safety has become a very prominent topic in our country, especially after the February 6 Maraş earthquakes. Living and working in earthquake-safe buildings should be seen as a fundamental right for all humanity. At this point, the emergency evacuation of a supermarket warehouse measuring hundreds of square meters, which has been determined to be earthquake unsafe, should be re-planned beyond the standard procedure. It will be one of the best examples of indoor navigation solutions for evacuating the warehouse and ensuring the safety of employees in this emergency scenario through Geographic Information Systems (GIS) using two-dimensional floor plans. Evaluating the end-to-end usage parameters of the warehouse in order to decide not only the shortest route but also the fastest and safest option in routing the mobility in the space will be an important criterion for creating the most appropriate evacuation scenarios. In any emergency scenario, a scenario designed only for the evacuation of the location will not be sufficient. At this point, it stands out that the evacuation from the dangerous place must be delivered to the distribution points as soon as possible. The delivery of medicines in a pharmaceutical warehouse that has been determined to be earthquake-insecure to the pharmacies in the affected area in the fastest and safest way can be arranged using location-based services. Dijkstra's Algorithm, which forms the basis of many researches when it comes to routing and shapes the working logic of GIS programs, was also used in this study. In particular, the necessity of stopping at more than one stop in creating the evacuation scenario and the necessity of fulfilling this obligation within safe borders exactly coincide with the framework of the Algorithm. The problem that stands out in the fictions created is defined as TSP and many different methods have been tried to solve it, and these methods continue to be developed. Starting from this point, the applications were completed in the supermarket warehouse setting by performing network analyzes in the QGIS environment, which stands out with its ease of access thanks to its free software, through indoor navigation. For the same warehouse, stops were detected by running analysis in ESRI ArcMap environment, again based on Dijktra's Algorithm. In this way, it was possible to make alternative observations. Subsequently, for the pharmaceutical warehouse evacuation, a scenario involving the pharmacies of the European Side of Istanbul was created and the shortest route was created in the ArcMap environment. The results of the thesis study were evaluated in two stages. The routes obtained for the supermarket warehouse were interpreted depending on the different examples seen during the research and the variability of the usage areas of indoor navigation. In pharmaceutical warehouse evacuation, evaluations were completed for safety and cost issues via a single route. From a broad perspective, the results of the algorithms and analyzes used to solve the TSP are associated with facility management
