Advanced Engineering Materials, EarlyView.Experiments and thermophysical simulations were conducted to investigate the electron beam powder bed fusion electron beam (PBF‐EB/M) process for the γ′‐strengthened nickel‐based superalloy Inconel 738LC. The results demonstrate the impact of process‐induced microstructural variations on high‐temperature mechanical behavior, providing a basis for ...

Proceedings of the twenty-fourth annual ACM symposium on Principles of distributed computing, 2005
In this paper, we initiate the study of the approximability of the facility location problem in a distributed setting. In particular, we explore a trade-off between the amount of communication and the resulting approximation ratio. We give a distributed algorithm that, for every constant k, achieves an O(√k(mρ)1/√klog(m+n)) approximation in O(k ...

In this paper, we consider a modification of the Weber problem which consists of locating a new facility on a sphere so that the weighted sum of distances to given demand points is minimized. Two ways of measuring distance are used. One is simply the length of shortest arc on the sphere.

In the Universal Facility Location problem we are given a set of demand points and a set of facilities. The goal is to assign the demands to facilities in such a way that the sum of service and facility costs is minimized. The service cost is proportional to the distance each unit of demand has to travel to its assigned facility, whereas the facility ...

On the Location of Hub Facilities
Transportation Science, 1988Hub Location problems have attracted considerable attention recently. In this note the multihub location problem is formulated and the condition under which a destination is optimally assigned to a hub facility is developed.

Transportation is one of the main contributing factors of global carbon emissions, and thus, when dealing with facility location models in a distribution context, transportation emissions may be substantially higher than the emissions due to production or storage.
