no. 1 approach

[0051] The production cycle analysis system of this embodiment analyzes the production cycle of a certain product PRD01. Each of the product PRD01 is processed by various semi-finished products through multiple processes, and each semi-finished product is processed through multiple processes.

[0052] The composition of this production cycle analysis system 100 is shown in figure 1 , including an operation performance information collection unit 101 , a storage unit 102 , a process analysis unit 103 , an abnormality determination unit 104 , and a display unit 105 .

[0053] Among them, the operation performance information collection unit 101 collects operation performance information of all the processes related to each product PRD01. The job performance information such as figure 2 As shown in (a), it includes the operation start time and operation end time of each process. The data source can be collected in real time at the manufacturing site or imported from other datab...

no. 2 approach

[0065] The configuration of the production cycle analysis system 200 of this embodiment is shown in Figure 4 , in addition to the same structure as the production cycle analysis system 100 of the first embodiment, it also includes a product analysis unit 201, which is used to analyze the production cycle of each product, including a product production cycle calculation unit 202, a product standard production cycle acquisition Section 203 and product delay time calculation section 204.

[0066] Among them, the product production cycle calculation part 202 calculates the product production cycle according to the aforementioned operation performance information for each product PRD01 (that is, products with the same product number but different product serial numbers) and stores it in the storage part 102. It refers to the time difference between the operation start time of the earliest process and the operation end time of the latest process among all the processes collected by...

[0073] The configuration of the production cycle analysis system 300 of this embodiment is shown in Image 6 , in addition to the same composition as the production cycle analysis system 100 of the first embodiment, it also includes a semi-finished product analysis part 301, which is used to analyze the production cycle of each semi-finished product, including a semi-finished product production cycle calculation part 302, a semi-finished product standard production cycle acquisition part 303, a semi-finished product delay time calculation part 304, and a semi-finished product dead time calculation part 305.

[0074] Among them, the semi-finished product production cycle calculation unit 302 calculates the semi-finished product production cycle for each semi-finished product of each product PRD01 according to the aforementioned operation performance information and stores it in the storage unit 102. The semi-finished product production cycle refers to the stored in the storage u...

Abstract

The present invention provides a production cycle analysis method and a production cycle analysis system capable of quickly locating a problem point causing an extension of a production cycle. The production cycle analysis system includes: a work performance information collection unit that collects work performance information for all processes related to each product, the work performance information including a work start time and a work end time of the processes; a process work time calculation unit that calculates a process work time, which is the time difference between the work start time and the work end time of the process, on the basis of the work performance information for each process for each product; a process standard operation time acquisition unit that acquires a corresponding process standard operation time for each process of the product; and a process delay time calculation unit that calculates, for each process of each product, a delay time of the process operation time of the process with respect to the corresponding process standard operation time as a process delay time of the process.

Description

technical field [0001] The invention relates to a production cycle analysis method and a production cycle analysis system for analyzing the production cycle of a product. Background technique [0002] In business activities, customers' needs are diversified and competition among enterprises is intensified. As a production enterprise, it is necessary to meet the requirements of customers in the production cycle. In the ordering stage, even if the price and quality of the product are ideal, if it takes a long time until delivery, the order may flow to a competitor. In order to shorten the production cycle, although the company has collected the current production cycle using various IT technologies, the use of data is not sufficient. For problem analysis and on-site improvement, it mainly uses human experience and knowledge, so reliability and versatility are lower. [0003] Patent Document 1 describes that in order to manufacture a built-in circuit, a plurality of steps are...
