The objective of this paper is to present the first results concerning the mapping and implementation of the Fuzzy Semantic Model (FSM) as a Fuzzy object-Relational database Model (FuzzORM). This solution permits to take advantages of both relational and object-oriented databases. The object-relational database management system PostgreSQL has been used for the implementation of the FuzzORM.

Discrete products are produced in enormous quantity and diversity all over the world. A global collaborative manufacturing environment requires the minimisation of environmental impact that these products shall ultimately pose. The implementation of an efficient product life cycle management system that encapsulates complete historical information about the product shall prove useful. This information may pertain to the design methodology, material type, details regarding manufacturing methods, use of coating or paints and exposure to radiation, chemicals of varying pH and electroweak forces during production or use. It is essential to have access to this information when the product is in use or in the disassembly stage at the end of the useful life of a product to accomplish the proper reuse or disposal of each component. A coding system that embodies the product life cycle stages for discrete products is envisaged. The proposed coding system stores parameters that are related to the design, manufacture, usage and disposal of a product. A computer programme is developed to establish a product life cycle code (PLCC) in the form of a 256-bit binary number or 64-bit hexadecimal number. The code can be allocated to a component or product at its inception in an interactive web session and stored in a repository for record keeping. The cradle-to-grave binary or hexadecimal code becomes an essential part of each component and product and facilitates the usage, disassembly and disposal of each component. A case study related to the generation of PLCC for discrete products is included towards the end of the article.

In this paper, based on possibility distribution and the semantic measure of fuzzy data, we investigate subclass-superclass relationships in the fuzzy object-oriented databases. We identify fuzzy class and develop soft computing methods in the paper to quantitatively determine the fuzzy subclass-superclass *** strategies to resolve the conflicts in multiple inheritance of class are also presented.
