Abstract

The main function of a heavy truck is to transport goods. Furthermore, the truck is directly operated by a driver, who has several additional functional requirements, of both ergonomic and communicative characters. Transport is a trust business and today’s just-in-time delivery systems rely on getting the goods on time. Product reliability, which is the ability of a system to perform according to its functional targets, is consequently a crucially important property for a heavy truck. This paper proposes a structure for a system reliability model that integrates different and complementary representations, such as Function-Means trees and Design Structure Matrix. The novelty of the presented approach is that it treats and integrates the technical and the human subsystems through the human-technical system interfaces in an extended DSM. The proposed reliability systems approach is verified with a component analysis case study of a truck cab and driver system.
