US graphite sourcing for electric vehicle battery applications
Abstract Graphite is a key material in electric vehicle batteries. Currently, China dominates global graphite production, and US sourcing of graphite could mitigate geopolitical supply‐chain risk. We explore the feasibility of domestic natural graphite sourcing in North America by characterizing current deposits and modeling the expected demand from ...

A simheuristic‐based algorithm for the stochastic long‐term maintenance scheduling problem
Abstract This work addresses the problem of assigning preventive maintenance jobs in a 52‐week planning horizon. Given a set of machines that need preventive maintenance, a set of maintenance jobs in these machines, a set of work teams, and a planning horizon, the problem consists of assigning each job to a work team in a given instant of the planning ...
