In this paper, we introduce the model REMES for formalmodeling and analysis of embedded resources such as storage,energy, communication, and computation. The modelis a state-machine based behavioral language with supportfor hierarchical modeling, resource annotations, continuoustime, and notions of explicit entry and exit points thatmake it suitable for component-based modeling of embeddedsystems.The analysis of REMES-based systems is centeredaround a weighted sum in which the variables representthe amounts of consumed resources. We describe a numberof important resource related analysis problems, includingfeasibility, trade-off, and optimal resource-utilization analysis.To formalize these problems and provide a basis forrigorous analysis, we show how to analyze REMES modelsusing the framework of priced timed automata and weightedCTL. To illustrate the approach, we describe a case study inwhich it has been applied to model and analyze resourceusageof a temperature control system.
