Project Tasks Dependencies and Constraints

Decent Essays

The network diagram is a logically schematic display provides graphical view for the project details like the tasks required to be performed, the relations between them and the duration’s estimations for the task itself and for the entire project including the earliest time to beginning the work in a every task the earliest predicted finishing date of the project. Network diagrams used for detailed planning, analyzing scheduling in project implementation and as a control tool in the monitoring and control phase. Two methods used to build the network diagram task-on-the-arrow (TOA) method and the recently one called the task-on-the-node (TON) method, or, the precedence diagramming method (PDM).

The relations between the two tasks called …show more content…

Like when we drill critical well the owner prefer to use FS than SS to avoid using high tech tools where it is too expensive or lake of experience worker can use these tools effectively.

2. Management Constraint, these constraints imposed by the management team as a result of the market or business changes. In the oil field management constraints take a huge space while determining the dependencies, for example, the price of the crude oil push the management team to increase the drilling operations or decrease it, hire new rigs and start new project or release rigs and cancel projects.

3. Interproject constraints, it typically happens when deliverables from a task in one project required by another task in different project and this most likely to occur when a huge project divided into small projects. In the oil field the owner companies splits the project to more than one project to facilitate management like drilling, completion and production. But the relations between these projects still had influence on the dependencies in each one of them. For example the production equipment order and receive should done before the production project starts and after a certain tasks finished in the completion project.

4. Date constraints, when forcing a task to a particular schedule as a result of imposing start or finish dates. Three forms can be used for
