Decision variables of case study
Continue the case study of the Capacitated Plant Location model of a car manufacture. You are given four Pandas data frames demand, var_cost, fix_cost, and cap containing the regional demand (thous. of cars), variable production costs (thous. $US), fixed production costs (thous. $US), and production capacity (thous. of cars). All these variables have been printed to the console for your viewing.

Exercise instructions
- Initialize the class.
- Define the decision variables using
LpVariable.dictsand python's list comprehension.
