摘要

A Markov Chain Monte Carlo (MCMC) implementation of Bayesian analysis can yield a probabilistic source characterization conditioned on available sensor data. Harrison and Wang (2009) proposed an MCMC approach tailored for water distribution systems with an emphasis on the proposal distribution, often the most problematic component of MCMC. Here, we present an adaptive framework of taking mobile sensor measurements to further complement the fixed sensors. It is implemented in a computationally feasible parallel implementation of the approach. The results demonstrate the potential of Bayesian analysis and the MCMC method for contaminant event management.
