Abstract. This paper presents the research conducted for the MARIDES project, which aims to improve the chartering process in shipping companies. MARIDES (Maritime Decision Support) focuses on the development of the necessary decision support software tools, which operate in an integrated environment. As far as decision support is concerned, given a certain chartering order, the system will estimate all the possible solutions (all vessels that can serve the given order) and it will present them to the user sorted, according to the estimated profit. Apart from deterministic data, stochastic data is utilized as well and the system will take into consideration data such as the future market potential. This is achieved through estimation of the ballast voyage in order to load the next cargo after the completion of the current order 1. Keywords: Decision Support System, Automatic Data Acquisition, Maritime Chartering Process.
