Answer:
A water quality sampling model
Explanation:
developed that provides a quantitative basis for determining sampling locations and schedules. The deterioration of water quality in distribution systems is known to correlate strongly with water age. The sampling model developed here uses water age as the basis for determining sample "representativeness." A mixed integer linear programming formulation is described and an example application is developed. The application illustrates how sampling objectives can be parameterized within the model and how unmodeled issues effect the implementation of the sampling plans produced.
