Embodiment 1

[0030] (1) The overall structure of the system

[0031] As shown in Figure 12, the bad object attribute information extraction system is an information processing device that can be connected to an external data storage unit 1208 via the Internet 1209, and is equipped with a main storage device 1207, a processing device (computing unit) 1203, and an auxiliary storage device. (storage unit) 1204 , input device (input unit) 1201 , and output device (output unit) 1202 constitute a device.

[0032] A block diagram of the system of this embodiment is shown in FIG. 1 . This is the case assuming the component is the object. The processing unit 104 executes each calculation process of receiving the survey target parts list (step 107), extracting part attribute information (step 108), correctness evaluation (step 109), and adding analysis priority (step 111). In this embodiment, each step 107-109, 111 is realized by executing software by such a general-purpose information processing ...

Embodiment 2

[0086] Fig. 8 shows an embodiment in which users use the system of the present invention when designing and verifying products.

[0087] When using this system in the design stage, it is considered that the user 811 is a designer, a quality assurance person, or a procurement person. The system receives the survey object parts list 801 input by the user through the input unit 802 , and generates the analysis priority parts list 804 through the parts information evaluation unit 803 . The evaluation unit 803 is connected to the user company management database 805 via the network 814, and can acquire component information including similar components. The system outputs the analysis priority component list 807 to the user side via the output unit 806 . In the output analysis priority parts list, the type code of the parts, the name of the least accurate substance group, and the judgment reason are described (list 708 in FIG. 7 ). After the user 811 issues a re-investigation req...

Embodiment 3

[0090] When using the system of the present invention in the manufacturing stage, it is considered that the user is a person in charge of production and manufacturing, a person in charge of quality assurance, or a person in charge of procurement. The business flow at this time is basically the same as that used in the design stage, but in order to identify the individual information of the parts, the parts list prepared by the user includes not only the type code, but also lot number, manufacturing number and other information.

Abstract

A system for inspecting components by evaluating the degree of accuracy of component attribute information provided by third parties, wherein a performance unit for performing the evaluation of the component attribute information comprises a unit for extracting components similar to target components; a unit for determining the abnormality of component attribute information when the component attribute information can take limited kinds of values; a unit for determining the degree of the abnormality of the component attribute information when the component attribute information can take unlimited kinds of values; and a unit for sorting the components in the order of descending degree of abnormality of the component attribute information to clarify the reason for the evaluation result.

Description

technical field [0001] The present invention relates to a method and system for evaluating the correctness of component attribute information provided by a third party, and in particular to a method suitable for quantifying and determining the degree of correctness of the chemical substance content information of components provided by a third party. A method and system for extracting bad part information of parts based on analysis of measuring equipment. Background technique [0002] At present, various countries are formulating and implementing the EU RoHS Directive (Rustriction of the use of Hazardous Substances: Directive on the Prohibition of Specific Chemical Substances) and the ELV Directive (End of Life Vehicles Directivu: Directive on Used Automobiles), etc., to restrict Regulatory system for the use of specific chemical substances. This trend of strengthening environmental regulation in recent years suggests that it may be extended to the addition of chemical subs...
