Method and device for forecasting demand for ship maintenance resources

Abstract

The present invention relates to a method and device for forecasting demand for ship maintenance resources. The method performs cluster analysis on historical dock repair data, obtains each dock repair level of each project and the corresponding required dock repair resource occupation time, and uses reverse analysis at the same time The ship status index corresponding to each dock repair level can be obtained by using the method; then according to the current operation status index of the ship and combined with the judgment of the operator, the dock repair level of the ship to be repaired is obtained; finally, the dock repair resource demand of the ship to be repaired is predicted according to the dock repair level . The present invention is suitable for forecasting the demand of occupancy resources such as personnel, facilities and equipment required for maintenance in the dock maintenance process of ships, adopts the method of fusing historical data and real-time information, establishes a statistical weighted prediction model based on fuzzy evaluation, and completes the Demand forecast modeling technology, through data fusion of historical and real-time data with certainty and uncertainty, gives demand forecasts for resources occupied by ship maintenance.

Description

technical field [0001] The invention relates to the technical field of forecasting of ship maintenance resources, in particular to a method and device for forecasting demand of ship maintenance resources. Background technique [0002] The demand forecast of ship maintenance resources is mainly to provide basic data for the optimal allocation of ship dock repair and maintenance resources, and to further provide scientific theoretical basis and feasible reference schemes for the business department to formulate maintenance plans for ship equipment, so that the plans formulated can be more accurate. Well meet the needs of ship use and maintenance. On the premise of ensuring the availability of ships, the life cycle costs are greatly reduced, and more significant economic benefits are produced. At present, in terms of ship maintenance resources, most of the research is on the method of determining the type and quantity of maintenance resources during ship construction. Among th...

Problems solved by technology

At present, in terms of ship maintenance resources, most of the research is on the method of determining the type and quantity of maintenance resources during ship construction. Among the established mathematical models, most of the studies are carried out on the optimal allocation of consumable maintenance resources, such as spare parts demand models, etc. , but there are few studies on the occupied resources such as manpower, facilities and equipment required for ship maintenance
