What are the characteristics of a project

A project has a defined life span with a beginning and an end. A project involves only personnel from one department in the organization and has an established objective.

Define work breakdown structure.

A tool used to progressively divide project work into smaller pieces

What are the two common techniques for drawing PERT networks?

AON and AOA

Give definition of the minimal-spanning tree problem

Connecting all points of a network together while minimizing the total distance of the connections.

Define the shortest-route technique.

Find the shortest distance from one location to another

What are the steps in budgeting process in project management

Identify all costs for each activity, identify how and when the costs will be actually spent, use earliest start time (EST) and latest start time (LST) to determine money spent per period.

Give an example of a work breakdown structure format.

Organizational chart, indented outline, and free form.

Define project crashing.

Reducing a project's completion time is called crashing. The activity on the critical path with the lowest crash cost per period should be crashed first.

Describe the concepts associated with CPM

The concepts associated with CPM are normal time, crash cost, normal cost

What is the objective of crashing a project?

The objective of crashing a project is to reduce the overall project duration.

Define an equilibrialized problem in a transportation problem

a balanced problem

What is said to exist when total demand equals total supply in a transportation problem?

a balanced problem

Define the expected time in PERT.

a weighted average of the most optimistic time, most pessimistic time, and four times the most likely time

A line in a network that may represent a path or a route is called a(n)

arc.

What does a line in a network represent?

arc.

Identify major phases of a project.

controlling, planning, and scheduling

CPM stands for

critical path method

What types of problem can the transportation models be for?

facility location

transportation models can be used for which of the following decisions?

facility location

Define pessimistic activity time.

he time an activity would take assuming very unfavorable conditions.

Describe slack time in a project network.

identifies the activities with zero times AND is the longest path through a project network that determines the project length.

The critical path of a network is the

longest time path through the network.

A point in the network, that is at the beginning or end of a route is called a(n)

node.

What does a point in the network represent?

node.

. PERT stands for

program evaluation and review technique.

PERT stands for

program evaluation and review techniques.

What is the earliest (activity) start time is in a PERT network referred to?

the earliest time that an activity can start without violation of precedence requirements.

Define critical path

the longest path through a project network that determines the project length.

Define the critical path of a network.

the path with zero slack.

What probability distribution does PERT assumes?

the total completion time of a project follows a normal probability distribution.

Slack time in a network is the

time an activity can be delayed without delaying the entire project.

Name the two most common objectives for the assignment problem

total costs or total time.

The two most common objectives for the assignment problem are the minimization of

total costs or total time.

The first step in planning and scheduling a project is to develop the

work breakdown structure.
