The programming and the control of the complex works execution
The application of this method consists in the a table elaboration, in which one may represent the activities sequence, taking into account the relations among them and their duration. The activities are graphically represented by bands that are equal in length with their duration. The graph is made up in a relative time scale, that has as origin the beginning of the first activity. When the momen[...]DOWNLOAD REFERAT

The next data must be known for this method development:
In the figure 2.1 the Gantt graph is presented for the mentioned work; we firstly have to consider the relative time scale. The answer obtained is 75 working days. On this basis we determine the beginning date for each activity (for instance, the F activity starts in the 27-Th day of the project).We can pass afterwards at the establishment of the starting moment, taking
into account the working days in a month. We may see that the work starts on Wednesday, 1St of April and ends on Monday, 20Th of July 1998.
The structure of a complex work, denominated PROJECT, is rendered by a The project-a collection of activities with definite beginning and end - is composed of activities and events.
The activity is a specific task that is part of the project and require time and resources for completion. The activity symbol, used in a graph, is an arrow, oriented to the right.
The event is a specific accomplishment at a recognisable moment, that occurs when all the former activities have been completed. The event symbol is the event that marks the end of an activity. The events are represented by circles and numbered in such a way that the end event of an activity is higher that the beginning one. « mai multe referate din Informatica
