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.
