Meanwhile, the quality management information generation system 300 generates the quality management related information using the measurement and analysis results of the measurement and analysis simulation system 200.

Specifically, the quality management information generation system 300 measures and analyzes the quality management information and uses the results stored in the quality management database server 500 to calculate and manage a quality assessment index for each structure to be measured, And an evaluation module 310. For example, statistical analysis of product quality index is performed based on measurement data and analysis data classified into information such as call number, block number, production organization, and the like. In this case, the quality index evaluation module 310 analyzes the measured value information of the degree of completeness of the error analysis and input completion, calculates the three-dimensional coordinate defective ratio (conformity rate ratio) of the X, Y and Z and the length, , The quality index of the member step difference is statistically analyzed and the quality evaluation index can be calculated using the simulation result to process the statistical analysis.

In order to calculate the quality evaluation index, it is possible to input cad file or image file information, bad mark-up on the drawing, remark display, target line / BLK input, author information, evaluation result,

In addition, the quality management information generation system 300 includes a structure deformation estimation module 330 that calculates a deformation of a structure by classifying dimensional error amounts according to a structure shape, a manufacturing environment, and a manufacturing method, and performs error pattern analysis. Here, the structure deformation estimating module 330 can estimate a shrinkage value (deformation amount) that can be generated when assembling various structures with welding based on measurement and analysis results.

In addition, the quality management information generation system 300 may include information on the measurement and degree of accumulation so as to ensure a result of a certain level or higher, regardless of who performs the job, including inexperienced persons, And an expert system module 340 for suggesting a work standard including measurement, analysis, and analysis.

For example, the expert system module 340 can ensure quality of a predetermined level or higher by providing and guiding each worker's work method according to a standardized process, and by reducing the work result deviation according to each worker, It also helps us to expect improvement.

The expert system module 340 includes an information extraction and storage module, a selection module, an analysis module, an evaluation module, and an intelligent task method presentation module.

Therefore, the information necessary for the preparation of the accuracy measurement chart means the main measurement position and measurement method of the main block to be managed and the equipment.
