Multi-criteria decision model and relief material distribution to damare IDP camp north east Nigeria

Abstract

This research focused on the optimization of marine vessels for the efficient distribution of relief materials to IDP camps in north eastern Nigeria. Optimizing marine vessels for relief distribution enhances the region's disaster preparedness by providing a diversified transportation network that can respond effectively to emergencies. The northeastern region of Nigeria has experienced ongoing conflict and security challenges. Marine routes may offer a safer means of transportation, reducing the risks associated with land-based convoys. Marine vessels can navigate through rivers and lakes, offering a faster and more efficient means of transporting relief materials compared to overland routes that may be congested or unsafe. The optimization process involves the consideration of several objective factors like operational cost, speed, fuel efficiency, route suitability/maneuverability, and serviceability. The decision-making process is often intricate and occasionally marked by conflicting criteria, which presents a notable challenge. In contrast to the traditional method of selecting marine vessels for various tasks, the AHP-TOPSIS approach offers a more systematic means of identifying the optimal choice, ensuring objectivity and coherence. Within this investigation, it was determined that the primary criterion of utmost significance, with a priority value of 0.416 based on the AHP method, was the reliability and safety of the vessel option. Other criteria, such as operational cost, speed, fuel efficiency, route suitability/maneuverability, and serviceability, held values of 0.110, 0.098, 0.114, 0.172, and 0.090, respectively. A total of nine alternatives were assessed: automated underwater vehicle, tugboat, F-25 boat, dinghies, small catamaran, pontoon boat, ferries, hovercraft boat, and kayaks & canoes. The outcome indicated that the small catamaran was the most suitable vessel for the distribution of relief materials. The methodology introduced in this study streamlines the process of optimizing vessel alternatives in a dependable and efficient manner.
