An operational planning for the Republic of Korea’s (ROK’s) Navy Ship could be divided into two domains in the fleet level. One is the operational scheduling in the aspect of the entire operation and the other is the berth allocation planning in naval ports.
For finding such an efficient operational planning, we may have to rely on a “model”, which is an abstract representation of the real problem.
The operational scheduling is to determine the available periods of each ship in this study. The ships’ “availability” means that their main systems—weapons, navigation, and propulsion—are in full operational readiness. If some of these major systems are not ready, then the ships should not be available for operations, as a high level of availability of the ROK Navy’s limited resources determines its Navy’s strength. However, if some ships are operated without proper maintenance only to improve their availability, this will result in inefficiencies. This study examines the operational scheduling for two squadron ships and considers multiple objectives, such as availability, the number of ships overlapping maintenance, and deviation from available ships in a particular week. This study applied the NSGA-II algorithm to find better solutions for more efficient scheduling. The experiment reached an efficient solution after 1,000 generations. Three efficient operation schedules were compared on the basis of three multiple objectives among the Pareto optimal set. Finally, this model lessened the deviation of available ships in a particular week, considering the ROK Navy’s limited resources.
The berth allocation planning is to establish an efficient berth allocation plan for navy ships in their home port within the constraints of limited resources such as berths and equipment. In general, navy ships require pier services such as maintenance and standby during their period in port. Berth allocation planning is a complex and challenging problem because of the inherent uncertainties in the maintenance requirements of each ship. In this study, to deal with this uncertainty, a scenario based stochastic programming model has been developed for the berth allocation planning. The model was formulated as a two-stage stochastic programming model based on the “fan of individual scenarios.” The scenarios were generated considering a maintenance requirement uncertainty which depends on the number of running days of each ship. The probabilities are estimated based on the historical maintenance data corresponding to the running days of each ship. The model is applied to the berth allocation problem in Korean naval ports. The expected benefit of the stochastic model was analyzed quantitatively based on the value of the information measured. The results indicated that the solutions of the stochastic model were much more effective than those of the deterministic model which shows only average results.
