A Broadened Criterion to Assess Safety Factor of Industrial Products Design for Ecological Balancing

摘要

The problem of selecting a suitable safety factor for industrial products, and especially for a design proposal is reviewed. Products are mainly introduced to provide a certain profit or turnover in terms of resources enhancement. However, any proposed product will somehow drain natural resources whether it operates properly or erroneously. A comprehensive definition of products safety is put forth to face the numerous requirements placed on sophisticated products. Product safety is then assessed based on its consequential loss in resources. The suggested definition is checked using the three commonly applied methods of product safety estimation; namely the product quality, the FMEA technique, and the Markov formulation. It is found that product safety in the broadened presented sense as a compromised viewpoint is often sought in order to reach a balance between their useful and harmful aspects with regards to all members of the ecological system. Moreover, product safety does embrace the gain/loss statistical data of product introductory versions and represents a trade-off function of its profits (resources renovation) and its losses (resources drain). In addition, the comprehensive resource-loss trend helps product designers meet a wide range of customer requirements and operational regulations as perspective environmental closed system (ECS).
