Claims (4)

  1. A production instruction support system that uses a computer having a processor and memory to support production instructions in a production site, The aforementioned processor, The system receives operational information, including 4M data related to production, obtained from data generation devices used in the production site when a predetermined on-site task is performed. The aforementioned operational information is stored in a database for each task performed at the production site. The system analyzes the difference between the predetermined production plan procedures and the operational information stored in the database, and outputs difference data for each task, including the changed business events and the factors that caused those business events, based on the results of the analysis. As a result of the analysis, the difference data is output to the computer screen and presented to the user . When estimating whether or not there has been a change in the business events of a business that has a predetermined relationship with a business that includes the business events in the differential data that have undergone the aforementioned changes, If the estimated change matches to a certain extent the change included in the output difference data, the difference data will be output for the business operations that have the predetermined relationship. A production instruction support system characterized by the following features.
  2. The aforementioned processor, Changes in business events of the aforementioned business that have a predetermined relationship and have been output more frequently are judged to be highly reliable changes. The procedures for the business operations, including the business events in which the aforementioned changes were determined, are to reflect the aforementioned highly reliable changes. The production instruction support system according to feature 1 .
  3. A production instruction support method performed in a production instruction support system that uses a computer having a processor and memory to support production instructions at a production site, The system receives operational information, including 4M data related to production, obtained from data generation devices used in the production site when a predetermined on-site task is performed. The aforementioned operational information is stored in a database for each task performed at the production site. The system analyzes the difference between the predetermined production plan procedures and the operational information stored in the database, and outputs difference data for each task, including the changed business events and the factors that caused those business events, based on the results of the analysis. As a result of the analysis, the difference data is output to the computer screen and presented to the user. When estimating whether or not there has been a change in the business events of a business that has a predetermined relationship with a business that includes the business events in the differential data that have undergone the aforementioned changes, If the estimated change matches to a certain extent the change included in the output difference data, the difference data will be output for the business operations that have the predetermined relationship. A production instruction support method characterized by the following features.
  4. Changes in business events of the aforementioned business that have a predetermined relationship and have been output more frequently are judged to be highly reliable changes. The procedures for the business operations, including the business events in which the aforementioned changes were determined, are to reflect the aforementioned highly reliable changes. The production instruction support method according to feature 3.

Description

This invention relates to a production instruction support system and a production instruction support method. Traditionally, various master data defining production site operations are generated during the production preparation phase. Production lines generate instruction information for various equipment from this master data, and production is carried out using this instruction information. While production site workers continuously improve their operations, changes resulting from these improvements, such as changes in equipment parameters or improvements to jigs, are rarely reflected in the master data generated during the production preparation phase. Therefore, discrepancies can arise between production plans based on master data that does not reflect these changes and actual production results using the improved equipment parameters and jigs implemented on the production site. In light of these problems, a technology has been disclosed that provides production instructions to workers while considering differences in equipment parameters and jig settings between the site and the plan, or between devices and factories (for example, Patent Document 1). Patent Document 1 describes an information processing device that supports production instructions at a manufacturing site, comprising: a data extraction unit that acquires actual data including Man data from the manufacturing site; and a work candidate calculation unit that estimates the current work status using a work model that associates the actual data with the work content at the manufacturing site.

The embodiments of the present invention will be described below with reference to the drawings. The following description and drawings are illustrative examples for illustrating the present invention, and have been omitted and simplified as appropriate for clarity of explanation. The present invention can also be implemented in various other forms. Unless otherwise specified, each component may be singular or plural. The positions, sizes, shapes, and ranges of the components shown in the drawings may not represent their actual positions, sizes, shapes, and ranges in order to facilitate understanding of the invention. Therefore, the present invention is not necessarily limited to the positions, sizes, shapes, and ranges disclosed in the drawings. In the following explanation, various types of information may be described using terms such as "database," "table," and "list," but these types of information may also be represented using other data structures. To indicate independence from data structure, "XX table," "XX list," etc., may sometimes be referred to as "XX information." When describing identification information, if terms such as "identification information," "identifier," "name," "ID," and "number" are used, these terms are interchangeable. When there are multiple components with the same or similar function, they may be described using the same symbol but with different subscripts. However, if it is not necessary to distinguish between these multiple components, the subscripts may be omitted in the description. Furthermore, while the following explanation may describe the processing performed by executing a program, the processor (e.g., CPU, GPU (Graphics Processing Unit)) executes the defined processing, using memory resources (e.g., memory) and/or interface devices (e.g., communication ports)
