Abstract Life-cycle assessments (LCAs) conducted, to date, of the end-of-life phase of vehicles rely significantly on assumed values and extrapolations within models. The end phase of vehicles, however, has become all the more important as a consequence of increasing regulatory requirements on materials recovery, tightening disposal restrictions, and the rapid introduction of new materials and electronics, all potentially impacting a vehicle's efficacy for achieving greater levels of sustainability. This article presents and discusses selected research results of a comprehensive gate-to-gate life-cycle-inventory (LCI) of end-of-life vehicle (ELV) dismantling and shredding processes, constructed through a comprehensive and detailed case study, and argues that managing and implementing creative dismantling practices can improve significantly the recovery of both reusable and recyclable materials from end-of-life vehicles.

The lean production system has been successful in the cost-based winning order criterion markets. However, the automotive market has been volatile and the new criterion of winning orders has been availability, which has called for an agile system. The present paper argues that because of fierce competition the current automotive market winning order criterion is now a blend of cost and availability. It shows how a hybrid lean-agile system can strategically meet such a challenging criterion. The study presents the drivers, attributes and providers in lean manufacturing, agile manufacturing, and hybrid lean-agile manufacturing systems. It investigates how the strategic facet of the proposed hybrid lean-agile manufacturing system addresses the six manufacturing competitive dimensions. It presents as well the hybrid lean-agile manufacturing key performance indicators.

The present paper aims at optimization of multiple quality characteristics (dimensional accuracy and surface roughness) in dry drilling Ti-6Al-4V using TiAlN-coated carbide tool while the controllable factors are spindle speed and feed rate. To do so, desirability methodology is used to explore optimum conditions for concurrent optimization of the addressed quality characteristics. Central composite design (CCD) is used for experimentation. In order to create reliable models describing the process behavior, response surface methodology (RSM) is used.

NASA has formed unfunded partnerships with four U.S. companies to develop new space capabilities available to the government and other customers. The Collaborations for Commercial Space Capabilities (CCSC) initiative is designed to advance private-sector development of integrated space capabilities through access to NASA's spaceflight resources and ensure emerging products or services are commercially available to government and non-government customers within approximately the next five years.

This SAE Aerospace Recommended Practice (ARP) provides recommendations for aircraft manufacturers and operating carriers about how to establish common information for the use of cargo systems with missing/inoperative restraints. Because of the fact that the certified restriction requirements due to missing/inoperative restraints are dependent of the specific aircraft structure and the system layout of the cargo loading system, this document shall only recommend common layout of information for the users based on the certified data provided to allow for common training, understanding and handling. This shall be used right from the beginning for future aircraft types for certified data.
