To calculate many of the important performance measures for an emergency response system one requires knowledge of the probability that a particular server will respond to an incoming call at a particular location. Estimating these “dispatch probabilities” is complicated by four important characteristics of emergency service systems. We discuss these characteristics and extend previous approxim...

This paper analyzes the effects of start-up costs of different technologies in providing electricity power. We explicitly solve a simplified linear formulation of the dispatch problem. Transforming this primal problem, we show that dominated technologies should be used only in the case of limited availability of efficient technologies. Furthermore, we develop a 'pen and paper' algorithm to dete...

A critical challenge in temporal planning is robustly dealing with non-determinism, e.g., the durational uncertainty of a robot’s activity due to slippage or other unexpected influences. Recent advances show that robustness is a better measure of solution quality than traditional metrics such as flexibility. This paper introduces the Robust Execution Problem for finding maximally robust dispatc...

The market distribution function is a probabilistic device that can be used to model the randomness in dispatch and clearing price that generators in electricity pool markets must take account of when submitting offers. We discuss techniques for estimating the market distribution function, and ways of measuring the quality of these estimators, using both classical statistical approaches and an ...

Understanding how people make decisions in actual, real-time operational environments can provide software developers with useful insights into how systems should be designed to support them. However, part of the difficulty is developing that understanding. In this paper we describe a case study of how Critical Decision Method interview data was analysed using the Emergent Themes Analysis Appro...

Clustering has been used as one of energyefficient mechanisms for data routing in wireless sensor networks. In hierarchical routing approaches, cluster heads are responsible for management (e.g. data aggregation, queries dispatch) and transmission of the collected data in the region controlled by them. For efficient data delivery, several researches have proposed various mechanisms for cluster ...

—The do-not-exceed (DNE) limit method was proposed to accommodate more variable renewable generation (VRG) securely. However, the lack of involving discrete recourse control precludes this method from gaining more flexibility for better VRG integration. This letter formulates a multi-period DNE limit model considering continuous and discrete recourse controls. This model belongs to two-stage ro...

Approximations made in day-ahead markets can result in suboptimal or even infeasible schedules for generating units and inaccurate predictions of actual costs and wind curtailment. Here we compare different optimal models of day-ahead markets based on unit commitment (UC) formulations, especially energyvs. power-based UC; excluding or including startup and shutdown trajectories; and determinist...

Introduction Public concerns about the adverse environmental and health effects of using fossil fuels to generate electricity have led to a greater dependence on renewable sources of generation, particularly in Europe. Since most of these sources are inherently variable, the electric utility industry is facing new challenges for balancing demand and supply in the real-time operations and market...
