The decision for remanufacturing as a life extension solution ageing equipment approaching their end of (EOL), has marginalized the active role end-users and maintenance functions, by predominantly considering remanufacturers (OEM/R) context. However, decisions influencing immediate core (used item/part its component) condition like corrective actions used, when to return or exchange with reman...

Based on damage data owned by PT XYZ, the compressor engine that has a history of high is D32 CP8 Compressor Engine. Critical components CP 8 are determined using risk matrix. The critical selected from Engine Screw Motor, Refrigerant Air Cooler, and Cylinder Bearing Oil Cooler. This study uses Reliability Centered Spares (RCS), Min-Max Stock, Reorder Point (ROP) methods. collection processing ...

This paper addresses the problem of allocating high-voltage transformer spares throughout the electric grid to mitigate the risk of random transformer failures. With this application we investigate the use of approximate dynamic programming (ADP) for solving large scale stochastic facility location problems. The ADP algorithms that we develop consistently obtain near optimal solutions for probl...

Solid rocket motor flows depend strongly on alumina granulometry, which spreads up with coalescence. Solving droplet sizes in unsteady flows is a modeling and numerical challenge, specially when high loadings generate retrocoupling. As an alternative to Lagrangian approaches, the Eulerian Multi-Fluid model describes polydispersity with size-sorted droplet fluids called sections. A two size mome...

Dr. Matthews has lectured to school children all over the country on the "facts of life". He spares us the bees and the pollen, and starts with how life began via the nucleus and pre-history. The plates and diagrams are clear and simple. He deals with the moral and spiritual significance of the sex relationship without sentimentality. He has not lost his own sense of wonder over the miracle of ...
