Model Hospital_cost
Title: Markov Chain
Description: This model evaluates the number of hospital patients in a variety of locations (states), changing over 90 units of time.  Evaluate the node "Patient numbers over time" and view it as a graph.~
~
The objective node, "Total cost" is a single number based on the assumption that costs are fixed over the 90 units of time.
