10.1The Avis car rental company successfully used the transportation method to move its inventory of cars efficiently.

ANSWER: TRUE

10.2Transportation and assignment problems are really linear programming techniques called network flow problems.

ANSWER: TRUE

10.3A typical transportation problem may ask the question, “How many of X should be shipped to point E from source A?”

ANSWER: TRUE

10.4The objective of a transportation problem solution is to schedule shipments from sources to destinations while minimizing total transportation and production costs.

ANSWER: TRUE

10.5Assignment problems involve determining the most efficient assignment of people to projects, salesmen to territories, contracts to bidders, and so on.

ANSWER: TRUE

10.6The objective of an assignment problem solution most often is to minimize total costs or time of performing the assigned tasks.

ANSWER: TRUE

10.7An important characteristic of assignment problems is that no less than two jobs or two workers are assigned to one machine or project.

ANSWER: FALSE

10.8The northwest corner rule, stepping-stone, MODI, and Vogel’s methods all produce integer solutions.

ANSWER: TRUE

10.9The MODI method is the Maximized Optimal Distribution method.

ANSWER: FALSE

10.10In the assignment problem, the costs for a dummy row will be equal to the lowest cost of the column for each respective cell in that row.

ANSWER: FALSE

10.11Linear programming techniques can be used to solve transportation problems and are more efficient than special purpose algorithms.

ANSWER: FALSE

10.12In finding the maximum quantity that can be shipped on the least costly route using the stepping-stone method, one examines the closed path of plus and minus signs drawn and selects the smallest number found in those squares containing minus signs.

ANSWER: TRUE

10.13In a transportation problem, the northwest corner rule is generally the most effective and efficient procedure to follow.

ANSWER: FALSE

10.14An advantage of the transportation and assignment problems is that the computational procedures virtually eliminate the possibility of multiple optimal solutions.

ANSWER: FALSE

10.15The Hungarian method is designed to solve transportation problems efficiently.

ANSWER: FALSE

10.16The transportation and assignment problems are the only linear programming problems for which we have special solution techniques.

ANSWER: FALSE

10.17From a practical perspective, it is always necessary to achieve an "optimal" solution to a complex assignment problem-a "very good" solution will simply not do.

ANSWER: FALSE

10.18In a transportation problem, each destination must be supplied by one and only one source.

ANSWER: FALSE

10.19In a transportation problem, a single source may supply something to all destinations.

ANSWER: TRUE

10.20One reason we choose not to apply the simplex method to the solution of assignment problems is that the Hungarian method is faster and easier.

ANSWER: TRUE

10.21A transportation model must have the same number of rows as columns.

ANSWER: FALSE

10.22The transportation method can be used to solve both minimization problems and maximization problems.

ANSWER: TRUE

10.23In the transportation model, we must always make the total supply equal to the total demand.

ANSWER: TRUE

10.24The stepping-stone method is simply an orderly process for investigating the solution at each possible "corner point" of the multidimensioned solution space.

ANSWER: TRUE

10.25In using the stepping-stone method, the path can turn at any box or cell which is unoccupied.

ANSWER: FALSE

10.26Using the stepping-stone...
