Benefits of using basic, imprecise or uncertain data for elaborating sewer inspection programmes

摘要: One key goal of sewer inspection programmes is to target segments in the worst condition. Despite development deterioration models, influence available data on models’ predictive power has not been studied depth yet. In this article, numerical experiments have conducted answer three main questions: (1) How can most probably within a utility be used define an effective programme? (2) Can we use auxiliary variable order compensate effects missing programmes? (3) Is it worth accept degree uncertainty instead having them? other words, preferable incompleteness database? respond these questions, considered asset stock and then degraded information by introducing uncertainty, imprecision within, form utility's database. The results show that significant improvement could...
