3. Process Flow Measures
Problem 1 (a)
1. Time Travelers Insurance Company (TTIS) processes 12,000
claims per year. The average processing time is 3 weeks.
Assume 50 weeks per year.
a) What is the average number of claims that are in process?
R per week
What is simulation?
Imposing uncertainty (probability
distributions) on inputs, per trial
Watch how output(s) vary under
Perform and analyze thousands

Identify the 4 key parts of the definition of GDP
How do we use G
Linear Regression, continued
Finally we can extend these mathematical
concepts to that of a conceptual model

Integer Linear Optimization
Recall solutions in LP
Before we tolerated decimal solutions to integer decisions
Decisions are scaled by orders of magnitude
Parameter uncertainty or approximations are relativel
By now you should feel comfortable with
f(x) = c1x1 + c2x2 + + cnxn
an LP problem
Define the decision var
