Various human activities and constant changing in the climate have contributed to the occurrence of disasters in various regions of the globe, enhancing the natural and socio-economic vulnerability in these regions. Scholars, government agencies and non-governmental institutions have concentrated efforts to create new procedures to mitigate disasters and promote humanitarian assistance. The need to effectively provide humanitarian relief to victims of disaster in the shortest possible time introduced a new area of knowledge, the humanitarian logistics. Combining knowledge of logistics and supply chain management business, humanitarian logistics is to apply those theory and corresponding practices in support of people affected by disaster events. This dissertation aims to contribute to the improvement of the procedure of collecting donations, avoiding the detour and streamlining the purchasing process and delivery of materials to the needy population. For this, we created a computer system that, through a website, receives donations and redirects them to a bank account to be determined, with the interface of a virtual store that will show first the supply needs in the disaster area (food, medicine, clothing, etc.) and then the total monetary value of the items and quantities chosen by the donor, which may be paid by the principal means available (credit card, debit card, transfer, billet). In particular, the proposed system takes into account the displacement of material, the existing deposits of materials and the price of the materials from suppliers to obtain the lowest total cost, that is, the total amount donated corresponding to the lowest prices of materials and the smallest displacements to the location of disaster, considering the capacity the deposits.
