Title: AID GOODS ALLOCATION–DISTRIBUTION INTEGRATION PLANNING FOR NATURAL DISASTER RELIEF WITH DIRECT SHIPMENT
Author: Oktarina, Rienna; Sutoko, Mame S.
Abstract: The aid goods distribution for natural disaster relief involves activities for delivering aid goods from supply nodes to demand nodes. In this case, the supply nodes are the places whith surplus of commodity or aid goods and the demand nodes are the places where the disaster occurred. A well-planned integration of allocation-distribution system of aid goods is essential to support a prompt supply of aid goods for minimizing the casualties and restoring the productive activities in the disaster area. This paper discusses a research on development of allocation and distribution model of aid goods for natural disaster relief. The objective function of the model is to minimize total unsatisfied demands for all necessary aid goods in all demand nodes throughout the planning horizon. The model considered multi commodities, multi transportation modes, multi vehicles, and multi periods. The model is decomposed into two sub models. Sub model 1 deals with the allocation problem of aid goods, and sub model 2 concerns with the assignment problem of vehicle distributing aid goods where their compositions and amounts are to be specified by Sub model 1. Allocation of aid goods in Sub model 1 considered weighted of commodities, so the solution of the developed model in sub model 1 obtained with Integer Linear Programming (ILP).The sub model 2 developed in this research also adopts maximum weight and volume of consignment to define load capacities of vehicles used in delivering the aid goods. The pattern of distribution is direct shipment; one supply node will supply multi commodities for many demand nodes. The purpose of this paper is to determine allocation model for both type and amount of aid goods which will be distributed from supply node to demand node.
