must satisfy all of the problem's constraints simultaneously.
A feasible solution to a linear programming problem _______
Arc
A line in a network that may represent a path or a route is called a
Linear Programming
A widely used mathematical programming technique designed to help managers and decision making relative to resource allocation is called
Safety Stock
Extra inventory that is used to avoid stockouts is known as
minimal-spanning tree
If your goal was to construct a network in which all points were connected and the distance between them was as short as possible, the technique that you would use is
an unbounded solution.
In a maximization problem, when one or more of the solution variables and the profit can be made infinitely large without violating any constraints, the linear program has
minimize the sum of carrying costs and ordering costs.
In making inventory decisions, the purpose of the basic EOQ model is to
maximize return on investment.
Linear programming is usually used by managers involved in portfolio selection to
analysis of how much the EOQ will change if different input values are used.
Sensitivity analysis of EOQ refers to

T or F A marketing research linear programming model can help a researcher structure the least expensive, statistically meaningful sample.
True
T or F A traveling salesperson might use the shortest route technique to minimize the distance traveled to reach one of his/her customers.

T or F A typical transportation problem may ask the question, "How many of X should be shipped to point E from source A?"
False
T or F Another name for the transportation problem is the logistics problem.
True
T or F Assignment problems involve determining the most efficient assignment of people to projects, salesmen to territories, contracts to bidders, and so on.
True
T or F If a linear programming problem has alternate solutions, the order in which you enter the constraints may affect the particular solution found.
False
T or F In a transportation problem, each destination must be supplied by one and only one source.
False
T or F In general, linear programming is unable to solve complex labor planning as the objective function is usually not definable.
False
T or F In the term linear programming, the word programming comes from the phrase "computer programming."

T or F Inventory is such an expensive asset that it may account for as much as 50 percent of a firm's invested capital.
True
T or F Management resources that need control include machinery usage, labor volume, money spent, time used, warehouse space used, and material usage.
False
T or F Safety stock is ignored when computing the reorder point.
True
T or F Sensitivity analysis enables us to look at the effects of changing the coefficients in the objective function, one at a time.

T or F The economic order quantity helps one estimate the optimal number of units to purchase with each order.
True
T or F The linear programming transportation model allows us to solve problems where supply does not equal demand.
False
T or F The purpose of the EOQ model is to achieve a balance between the cost of holding inventory and the cost of stockouts.

T or F Transportation models may be used when a firm is trying to decide where to locate a new facility.
True
T or F We may begin the maximal-flow technique by picking an arbitrary path through the network.
False
T or F When two or more constraints conflict with one another, we have a condition called unboundedness.
