A chemical substance total management system aids for reduction of release and transferring amount of managing substances in business entities. The system retrieves releasing and transferring amount record relating to predetermined managing substance on the basis of total tabulation link information with correlation between the tabulation result record managing releasing and transferring amount of managing substance per releasing and transferring destination and releasing and transferring amount record to be a source generating tabulation result record.

Chemical substance total management system, storage medium storing chemical substance management program and chemical substance total management method

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.

Chemical material integrated management system and method thereof

The present invention provides a method and system for management of chemical materials comprising the steps of providing a first data set containing which substances comprise the materials, providing a second data set containing which of the substances are to be controlled, providing a third data set containing a ratio of discharge of the controlled substances in a process, analyzing a preset amount of the materials in the process and determining a quantity of the controlled substances utilizing the first and second data sets, determining an emissions quantity of the controlled substances utilizing the ratio and the quantity of the controlled substances and maintaining the third data set according to a preset interval of time.

Method and system for comprehensive management of chemical materials

Electronic information input via an input means is divided into first and second groups e.g. representing information which may not be modified except by a skilled operator, and information which may be modified freely. The information is stored in an information file and display elements are stored in e.g. a related information file. If a request for modification of one of the information elements is input via the input means, a judging means determines, on the basis of controlling information in a controlling information area, whether the information element belongs to the first or second group. If it belongs to the first, a display means displays one of the display elements as e.g. a warning to the operator that the information element may be modified only by a skilled operator. A password system may be provided to identify such a skilled operator.
