Suppose an LP problem was subject to constraints of
2X+Y>= 10
X+3Y>= 20
Suppose that a new constraint is added, of the form 3X+A*Y>= 90. What is the largest
value that A can have so that this new constraint is redundant?
Every month, a distribution center will deliver 14,000 units to Retailer A at coordinates
(20, 10), 12,000 units, to Retailer B at coordinates (30, -15), and 20,000 units to
Retailer C at coordinates (4, 4). Assuming no constraints on location, at what
coordinates should the distribution center be located (rounded to two decimal places)?
A manufacturing firm is considering three potential locations for a new parts
manufacturing facility. A consulting firm has assessed three sites based on the four
factors supplied by management as critical to the location’s success. Given the
management-supplied factor weights and the consultant team scores, which location
should be selected? Scores are based on 50 = best. Do the results surprise you in any
way? Comment.
In addition to labor, to which other variables have learning curves been applied?
A linear programming problem contains a restriction that reads “the quantity of X must
be at least twice as large as the quantity of Y.” Formulate this as a constraint ready for
use in problem solving software.
Location A would result in annual fixed costs of $300,000 and variable costs of $55 per
