The invention aims at providing a work performance collection system for reliably collecting information of work performance without applying a burden to a worker in assembly of a work object article. This system includes a work specification ID tag into which information for specifying a work content of a work object article is written, a work management box having a throw-in port into which the work specification ID tag is thrown at the time of work, and an ID tag reader provided to a side surface of the work management box, for reading the work specification ID tag and transmitting the information read to a work performance management apparatus. A worker is required to only throw the work specification ID tag into the work management box at the start of work and to only take out the work specification ID tag at the end of work.

The present invention is related to a component and material traceability control apparatus for controlling manufacturing lot identification information of any of a component and material constituting a product manufactured according to a process where a manufacturing apparatus with not less than one component and material reserve unit picks up a needed amount out of the component and material reserved in the component and material reserve unit and manufactures the product, and the component and material traceability control apparatus is equipped with at least a processing unit, a memory unit used as a work area by the processing unit, a manufacturing performance information memory unit, a component and material supply performance information memory unit, and a manufacturing lot trace information memory unit.

Component and material traceability control apparatus, control method, control program, and control program memory medium

A chemical substance total management system and a chemical substance total management method which can easily manage amounts and release destination of managing substances. The chemical substance total management system includes a material composition database of component composition information of material or product in a form of database, a managing substance database in a form of a list of substance requiring management, for identifying substances constituting the material or product on the basis of the material composition database and identifying substance required management on the basis of the managing substance database for managing chemical substance contained in the material handled by a business entity or product. The system further includes release coefficient database storing weight ratio data in each transfer and release destination per the identified management required substance in a form of database.
