A natural spring water company in Ontario is considering three possible improvement projects for its plant: a new water filtering equipment, a new software program for controlling operations, and expanding the warehouse used for storage. A BBA student begins to formulate the integer programming problem: Decision variables x1 = 1 if water filtering equipment is funded and, o otherwise x2 = 1 if software for operations is funded and, o otherwise x3 = 1 if warehouse expansion is funded and, o otherwise What constraints will ensure the following conditions? Question 5 (1 point) At least two out of the three projects have to be funded: O x1 + x2 + x3 = 2 x2 + x3 >= 2 x1 + x2 >= 2 The new water filtering equipment can be funded only if the software was purchased too, how will you modify the formulation? 3 w 3 Ox1 >= x2 O x1
