Marine traffic risk modelling – an innovative approach and a case study
PublikacjaThis paper presents a model to analyse the risk of two common marine accidents: collision and grounding. Attention is focused on oil tankers since they pose the highest environmental risks. A case study in selected areas of the Gulf of Finland in ice-free conditions is presented. The model utilizes a formula for risk calculation that considers both the probability of an unwanted event and its consequences. The model can be decomposed...

Towards the Development of a Risk Model for Unmanned Vessels Design and Operations
PublikacjaAn unmanned merchant vessel seems to be escaping from the stage of idea exploration. Once the concept proofs its safety, it may become a part of maritime reality. Although the safety aspect of such a ship has been addressed by a handful of scholars, the problem remains open. This is mainly due to lack of knowledge regarding actual operational circumstances and design of unmanned ships, which are yet to be developed. In the...

A Simulation Model for Risk and Pricing Competition in the Retail Lending Market
PublikacjaWe propose a simulation model of the retail lending market with two types of agents: borrowers searching for low interest rates and lenders competing through risk-based pricing. We show that individual banks observe adverse selection, even if every lender applies the same pricing strategy and a credit scoring model of comparable discrimination power. Additionally, the model justifies the reverse-S shape of the response rate curve....

A unified measure of collision risk derived from the concept of a ship domain
PublikacjaW artykule zaprezentowano nową miarę ryzyka kolizji dwóch statków, wywiedzioną z koncepcji domeny statku. Jej prostota oraz fakt, że uwzględnia ona kursy obydwu statków czynią ją dobrą alternatywą dla często stosowanego pojęcia odległości największego zbliżenia. Miara ta jest elastyczna, tzn. można korzystać z niej w powiązaniu z dowolną, zadaną domeną statku. Szczegółowo przedstawiono wyprowadzenia wszystkich niezbędnych wzorów...
