Competition is the driving force of today's economy and it is vital for organizations to gain competitive advantages. In recent years, outsourcing has been the focus of managers as a tool for developing organizations and improving productivity. This study deals to analyze the outsourcing risks of the supply chain in the automotive industry using fuzzy inference systems. For this purpose, in the...

Automotive Safety Integrity Levels (ASILs) are used by ISO 26262, the new automotive functional safety standard, to categorize the stringency of safety requirements. In the course of a hierarchical system design, ASILs are iteratively allocated to subsystems and components. This ASIL decomposition allows for redundant elements to share the responsibility of meeting a given ASIL and finding effi...

A fully equipped automotive air-conditioning test system consists of 5 main components: a compressor, a condenser, an orifice tube, an evaporator and an accumulator. R-134a is used as refrigerant. The coefficient of performance, evaporator cooling capacity, compressor power consumption, total mass flow rate, vapor mass flow rate, liquid mass flow rate and oil in circulation, pressures and tempe...

Automotive industry observers note that a transformation is occurring where automotive OEMs are delegating more responsibilities to their suppliers. Instead of purchasing individual components, the OEMs are purchasing sub-assemblies. The suppliers are expected to do their own engineering. Many in the CAE community realize that there are many challenges to be faced in coordinating CAE activities...

This paper describes an approach towards an adaptive software and system architecture for driver assistance systems (DAS). Rather than assuming a static configuration of electronic control units and software components used in current automotive systems, we propose an architecture approach to handle the diversity arising from dynamically changing software configurations as they will emerge in f...

Bearing designers have expanded their use of advanced Finite Element Method (FEM) as a result of improvements in computer hardware and software. Automotive bearing designers increasingly apply Finite Element Analysis (FEA) to the design of integrated automotive bearing products which tend to evolve gradually into sophisticated components. FEA is an effective tool that enables NSK to develop and...

Even small changes in automotive networks might have harmful impact to the correctness of the functionality due to changed timing behavior. In this paper, we present an approach to investigate the functional and timing-behavior of an automotive network at a very early design stage. To reach this goal, a virtual prototype of an automotive network is created. The prototype is used as a model for ...

Electronics technology is indispensable for improving automotive performance. Especially, in electric vehicles (EV) and hybrid electric vehicles (HEV), electric systems are the heart of the automobile. Power devices are one of the most important components of car electronics systems and they are applied to many systems, for example, oil-pressure valve control of the ABS system, and motor contro...
