Research Of Measuring Ship Piping Fixed Working Hours Based On The Knowledge Base

Ship piping fixed working hours is the ship construction plan, cost accounting, and schedule control important basis, the current domestic mainly rely on manual read design information from a large number of drawings, again according to the norm of this measure, big workload, low efficiency, poor accuracy, design drawings, at the same time quota calculation and task dispatching, each other can't achieve the goal of design, production, management integration.According to "the design, production, management, information integration" thinking, in the thorough analysis of ship piping design data characteristics and ship design software TRIBON data extraction methods on the basis of the definition of piping design content extraction parameters of piping is established each professional, each type of work, the design of each station data extraction model knowledge base, between design data and man-hour estimates in the formation of the common interface configurable processing pattern, implements the design and production of data integration and sharing.At the same time, ship production quota time calculation is based on quota standards, professional, different type of work, location, according to the quota standards is different, have different methods, the paper comb in piping fixed working hours, on the basis of standard system, established a fixed working hours standard knowledge base, defines each location fixed working hours calculation model, logical reasoning and knowledge base will extract data basis for the design of the measurement model matching standards system, measuring method and measuring rules, data of the measured object fixed working hours.Finally through actual application system development and enterprises, to verify the effectiveness of the extraction model and calculation method.Piping fixed working hours calculation method based on knowledge base to improve the measuring accuracy and standardization, in order to strengthen the management of working hours for the shipbuilding enterprises provides a meaningful reference, in which the enterprise man-hour quota standards system is a ship in the measuring system of important external support knowledge base, along with the enterprise production environment, equipment modification, process improvement, and the change of personnel ability, shall be revised correspondingly to quota standards system, so as to adapt to the actual situation of enterprises.
