Embodiment Construction

[0028] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] The present invention has designed a kind of WBS-based shipbuilding standard man-hour data mining method, in the actual application process, specifically comprises the following steps:

[0030] Step 001. Divide the hull according to the manufacturing level to obtain the production activities corresponding to the hull; divide the outfitting according to the operation type to obtain the production activities corresponding to the outfitting, and thus obtain the hull, outfitting, and painting respectively. The corresponding production activities, that is, obtain the production activities in the shipbuilding process, and then go to step 002.

[0031] Step 002. Separately divide each production activity in the shipbuilding process, obtain each task package corresponding to each production activity, and proceed to step 0...

Abstract

The present invention relates to a WBS-based ship construction standard man-hour data mining method. The WBS-based ship construction standard man-hour data mining method solves the disadvantage that the conventional weight estimation is large in error, fundamentally avoids the problems that the time limit of a project is uncertain, the cost is difficult to control, etc., which are caused by a conventional weight estimation method, and is characterized by carrying out the regression analysis by taking the historical ship construction data as the basis to obtain the curves of man hours and the object amount influence factors, thereby obtaining the high-precision man-hour data, providing the accurate data support for the ship construction, and being able to improve the ship construction efficiency effectively.

Description

technical field [0001] The invention relates to a WBS-based data mining method for standard man-hours of shipbuilding, and belongs to the technical field of formulating standard man-hours of shipbuilding. Background technique [0002] Man-hour data is an important basis for planning and load calculation in the process of ship construction, and is also the basis for cost budget and control of ship construction. However, at present, shipbuilding companies often only use the construction weight to make a rough estimate of the man-hours of ship construction. This estimation method has a large error and has not been subdivided into the man-hours of each operation link of ship construction. Such an unreasonable and unspecific man-hour The estimating method leads to problems such as uncertain construction period and difficult cost control. [0003] Therefore, in order to overcome the shortcomings of the traditional man-hour data mining method, which is extensive and greatly influe...
