Fleet policy matters because a great deal of cost can be saved if liner companies work out a well-done fleet policy. Based on a long-term business, liner company should take the multi-period fleet deployment and the exercise of finance into consideration. However, most literature before only discuss the single problem of fleet deployment or composition or of fleet deployment in an uni-period.
Through analyzing the fleet composition data of the world top 20 of container liner companies, we find that their strategies are very different. Furthermore, we explore the necessarily considered factors in making decisions as the fundamental knowledge for our studies. A mathematical model is formulated to decide the composition and deployment of owned and charter ships at every planning period. This model minimizes the sum of operational expenditures and investment costs but is subject to the minimal carrying requirement of each route and the operational characteristics of shipping lines. We employ a commercial package, OPL, to examine an example that we illustrate in our study. The results show our model can sufficiently reflect the problem of the practical planning.
We use the empirical case to test the model; the object of the model is to find the minimum cost. In sensitivity analysis, we focus on parameters about owned-ships limits, chartering rates and the needs of routes. We analyze the different cases to see the meanings of changes of the objective values. Further tests can be executed with the practical data for obtaining more valuable reference.
Key word: fleet planning, fleet deployment, fleet composition
