The network below describes the interrelationships of several activities necessary to complete a project. The arrows represent the activities. The numbers between the arrows indicate the number of months to complete each activity.


The shortest time to complete the project is:

  1. 5 months.
  2. 6 months.
  3. 8 months.
  4. 14 months.

Answer(s): C

Explanation:

The critical (longest) path through the network from node (A) to node (F) is path A-C-D-F. All other paths are shorter than path A-C-D-F, so the activities along those paths can be completed before the activities along path A-C-D-F. Thus, the shortest time to complete the project is 8 months (3 + 3 + 2).



A shortest-route algorithm is used in network models to:

  1. Identify bottlenecks in a network and hence identify the longest path.
  2. Minimize total travel time from one site to each of the other sites in a transportation system.
  3. Maximize throughput in networks with distinct entry (source node) and exit (sink node) points.
  4. Identify the set of connecting branches having the shortest combined length.

Answer(s): B

Explanation:

Network models are used to solve managerial problems pertaining to project scheduling, information systems design, and transportation systems design. Networks consisting of nodes and arcs may be created to represent in graphic form problems related to transportation, assignment, and transshipment. The shortest-route, minimal spanning tree, and maximal flow problems are other applications of network models. A shortest-route algorithm minimizes total travel time from one site to each of the other sites in a transportation system.



The following information and diagram apply to a project:


The earliest completion time for the project is:

  1. 11 days.
  2. 14 days.
  3. 15 days.
  4. 20 days.

Answer(s): C

Explanation:

The two paths through the network are A-C-E (5+4 + 6= 15days) and B-D-E (3 + 2 + 6 = 11 days). The critical or longest path is thus A-C-E. Hence, the earliest completion time is 15 days.



Which of the following terms is not used in project management?

  1. Dummy activity.
  2. Latest finish.
  3. Optimistic time.
  4. Lumpy demand.

Answer(s): D

Explanation:

Project management concerns managing teams assigned to special projects. Lumpy demand refers to periodic demand for a product or service that increases in large, lumpy increments.
