( Elsevier , 2016 , Article)We investigate the problem of designing an optimal annual delivery plan for Liquefied Natural Gas (LNG). This problem requires determining the long-term cargo delivery dates and the assignment of vessels to the cargoes ... -
Optimal replacement last with continuous and discrete policies
( Institute of Electrical and Electronics Engineers Inc. , 2014 , Article)This paper proposes age and periodic replacement last models with continuous, and discrete policies. That is, an operating unit is replaced preventively at time T of operation as a strategic policy, or at a number N of ... -
Optimal skill assignment with modular architecture in spare parts supply systems
( Institute of Electrical and Electronics Engineers Inc. , 2017 , Conference Paper)We study a single location supply system for repairable spare parts. The system consists of a multi-server repairshop and inventory of ready-to-use spare parts. When a failed part is received, a new (or as-good-as-new) ... -
Optimal utilization of geothermal heat from abandoned oil wells for power generation
( Elsevier Ltd , 2019 , Article)Unlike other types of renewable energy, geothermal resources represent a stable energy source because they can be exploited regardless of meteorological conditions. In geothermal systems, heat is exchanged between the ... -
Optimising stop-bands in periodic waveguides using genetic algorithms and wave finite element method
