Improvement Curve Cost Model and Revenue Cost Model

fter 20-30 years ships are at the end of their effective service life [9] and they are then dismantled. Ship dismantling in the US is quite different from in developing countries, and ship deconstruction costs are much higher in the US. The ship deconstructors in developing countries earn significant profits because of lower recycling costs of the ships and higher resale values of the scrap. Previous cost models [4,3] developed estimated the cost of ship deconstruction, but the improvement effects from learning were not included. The data on the ship deconstruction cost were sparse, and the improvement curve or learning curve theory was applied to the available data to develop an improvement curve cost model for ship deconstruction.
