A Reschedule Design for Disrupted Liner Ships Considering Ports Demand and CO2 Emissions: The Case study of Islamic Republic of Iran Shipping Lines

This study presents a MILP model to retrieve or get close to the early schedule of disrupted container vessels. The model is appliedon a realcase study of Islamic Republic of Iran Shipping Lines (IRISL) considering container demands, and CO2 emissionssolvedwith CPLEX GAMS solver in less than a minute. Sensitivity analysis on fuel inventory level shows the inevitable influence of the fuel price and primary inventory level on ships costs. Variations in unavailability duration of the ships suggest that substantial changes in the objective function caused by omitting the port calls rather than speeding up the ships.
