DEVELOPMENT OF A PRODUCTION INFORMATION MANAGEMENT SYSTEM TO SUPPORT ENVIRONMENTAL CSR ACTIVITIES FOR PROCESS PRODUCTION

摘要

Recently, awareness of Corporate Social Responsibility (CSR) has been raised and various environmental regulations have spread in many countries. Under this situation, manufacturers of process production, production information management systems are required that can archive and retrieve data not only of final products and raw materials but of chemical substances contained, intermediate products and wastes generated, and energy consumption during the production. However, management systems and product models currently used for assembly production do not fit the above requirement. To solve the problem, first, an object-oriented process-product model was designed which can represent these data and can be easily implemented on commercial ORDBMS. Second, traceability functions of explosion and implosion covering chemical substances, intermediate products, wastes and energy were developed on the ORDBMS. Third, a generic environmental law model was designed which can represent restrictions of various environmental regulations in a uniform way. Finally, a conformance checking function for environmental regulations was developed by combining the generic environmental law model with the process-product model. The effectiveness of the models and functions was verified by applying them to full-scale production data of functional polymer films and checking its conformance to RoHS and EuP directives.
