Two Aspects of Alien Species Management in a Seaport : Ship Classification and Ship Inspection Costs

Abstract

The many aspects of alien species management normally all involve decision making over time and under uncertainty. Therefore, in this note, we focus on an arbitrary seaport in a country called Home and we conduct a dynamic and stochastic analysis of two questions that have received insufficient attention in the extant literature on alien species management. First, we provide a particular way of classifying ships that enter the Home seaport from K possible countries in the time interval [0, t]. Second, we characterize the total cost of inspecting the ships that arrive in the Home seaport during the same time interval [0, t].
