Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention.

In the parts information system 1 according to the present invention, the procurement information collecting unit 2 collects, as the procurement information, an order summary for each manufacturer from the separately provided procurement management system 10 in units of parts items. Units and order summary Collect unit price by unit, acceptance inspection quality, procurement lead time record, and delivery date compliance rate record. In this case, the collection period has a function of setting it in parts item units and parts classification units such as the past one month and six months. The procurement easiness calculation unit 3 has a function of calculating a procurement easiness index, which is an index of procurement easiness , based on the data collected by the procurement information collection unit 2. The component information management unit 4 has an interactive search function with a separately provided terminal device 5, and based on the procurement easiness index, procurement targeting a specific component or a plurality of components constituting one function. Outputs easiness data.

Next, the operation will be described.

Since the operation of the procurement information collecting unit 2 is a data reading operation from a storage carrier which is a general function of a computer, its explanation is omitted. Next, the operation of the procurement easiness calculation unit 3 will be described. FIG. 2 is a flowchart of the operation of the procurement easiness calculation unit. The procurement easiness calculation unit 3 reads the procurement information collected by the procurement information collection unit 2 in step (hereinafter referred to as S) 1. Next, the procurement easiness factors P1 to P10 are calculated using the procurement information previously read in S2. Here, the contents of the procurement easiness elements P1 to P10 will be described. These are all in terms of parts items P1: 1 / number of manufacturers P2: average purchase unit price P3: minimum order summary amount P4: order summary gradient index = unit price at maximum order summary amount / unit price at minimum order summary amount P5: Average of defective rate of incoming inspection P6: Standard deviation of defective rate of incoming inspection P7: Average value of procurement lead time P8: Standard deviation of procurement lead time P9: Average value of late delivery rate P10: Standard deviation of late delivery rate Calculate the above values.

Regarding these procuring easiness elements P1 to P10, the procuring easiness standard values P01 to P10 are preliminarily set for each specification category which is a classification based on the similarity of specifications of parts.
Set 010. In the case of this embodiment, the average of the past 12 months of each procurement easiness factor is taken and the procurement easiness standard value P01
~ P010. Further, since the procurement easiness calculation unit 3 has an interactive correction function for the procurement easiness standard value and can correct the calculated average value, whether or not the standard value needs to be corrected in S3 If necessary, the correction value of the standard value of the easiness of procurement is input in S4, and then the easiness of procurement index (hereinafter, referred to as PP in the mathematical formula) is calculated from the easiness of procurement elements P1 to P10 in S5. To do. If it is not necessary to correct the standard value in S3, the procurement easiness index is directly calculated in S5. Here, a method of calculating the procurement easiness index will be described.

The easiness of procurement index is 1 as shown below.
Calculate by formula.

PP = Σmi × Pi / P0i …………………………………………………………………………………………………………………… 1 where mi is a value indicating the weighting of the procurement easiness factor Pi (mi = 0 to 1). Indicates. mi is to take into consideration that the procurement easiness factors to be emphasized differ depending on the type of business. For example, in a high-mix low-volume assembly business,
In projects with extremely low repeatability, the minimum order volume P3 must be emphasized over the order summary slope index P4. Next, the procurement easiness index calculated in S5 is output to the parts information management unit 4, and the processing of the procurement easiness calculation unit 3 is ended.

Next, the contents of the procurement easiness information provided from the parts information management unit to the design engineer will be described.

The parts information management unit 4 has an interactive search function according to the specifications with the terminal device 5, and simultaneously provides the item name / unit price and the procurement easiness index as a primary search function. Also, as a secondary search function,
It has a search function for the element of easiness of procurement of multiple parts with specified specifications. Further, for each design unit, for example, for each printed circuit board mounting design unit, the average value of the easiness of procurement index, the average value of the easiness of procurement element, and the procurement lead time of all the components used in the corresponding design unit. With the function to search and display the distribution of.
