CN21 - Create Network Project Systems - Network and Activity
A network can represent the sequence of activities in a project or the sequence of a single activity within a project. You can graphically display various structural elements of a project and their interdependencies in the Project System.
During the life of a project, networks are used as a basis for planning, analyzing, controlling and monitoring schedules, dates, and resources.(such as personnel, machines, PRTs, materials, documents, and drawings).
The following are examples of the types of questions you can answer with the information you get from a network:
Where are we unclear on the processes in the project and what are the possible consequences?
Where are the scheduling uncertainties and how significant are they?
When and in what amount do we incur costs and make expenditures for this project?
When and in what quantity do resources have to be available so that we can keep to the schedule?
In the Project System networks are activity-on-mode networks.
The essential components of a network are:
. Activities
. Relationships between the activities
Activities
The most important data describing an activity in the Project System is:
. Work center in which the activity is to be carried out
. Duration of the activity
.Start and finish dates for the activity
.Resources required to carry out the activity
. Texts and documents describing the activity
Relationships
There is usually a reason for a specific sequence of activities in a network. For example, there may be technical dependencies between individual activities. These dependencies are represented by relationships in which one activity is the predecessor or the successor of another activity.
The relationship type specifies how the individual activities are linked with each other:
.Finish - Start (FS) Relationship
Relationship between the finish of one activity and the start of its successor.
. Start - Start (SS) Relationship
Relationship between the start of one activity and the start of its successor.
.Finish - Finish (FF) Relationship
Relationship between the finish of one activity and the finish of its successor.
. Start - Finish (SF) Relationship
Relationship between the start of one activity and the finish of its succes

十分感谢，虽然看了还是不是很明白，但是可以从这入手。
这个是做Project schedule的？这个会跟Accounting 有什么关系呢，会计需要这个来做什么？
Project cost 和这个有关吗？
