Research on the Optimal Economic Life of Operational Ships of Antong Holdings
Journal: Modern Economics & Management Forum DOI: 10.32629/memf.v7i1.4916
Abstract
Aiming at the aging pressure faced by the operational ships of Antong Holdings, this study systematically explores the optimal economic life of various types of ships and formulates scientific ship renewal decision suggestions based on the historical operational data of the company's 63 operational ships through data collection, preprocessing, trend fitting, model construction, and multi-scenario verification. The research constructs a ship operating cost data analysis model and a multi-dimensional renewal model, clarifies the optimal economic life intervals of container ships, bulk carriers, and multi-purpose ships, and provides core support for the enterprise to optimize the fleet structure, reduce operating costs, and improve economic benefits.
