We study the problem of achieving a given value in Markov decision processes (MDPs) with several independent discounted reward objectives. We consider a generalised version of discounted reward objectives, in which the amount of discounting depends on the states visited and on the objective. This definition extends the usual definition of discounted reward, and allows to capture the systems in ...

Lot output time prediction is a critical task to a wafer fabrication plant (wafer fab). To enhance the effectiveness, a look-ahead FBPN incorporating the future release plan is constructed in this study. Three nearest exponentially discounted future workloads, modified from Chen’s nearest future discounted workloads, are proposed for the look-ahead function. According to experimental results, t...

Wave energy provides a renewable and clear power for the future mix fights against climate change. Currently, there are many different wave converters, but their costs of extracting still much higher than other matured renewables. One best indicators calculating generating cost is ‘levelized energy’ (LCOE), which combined capital expenditure (CAPEX), operational (OPEX), decommissioning with inc...
