I have a Project made up of tasks. Each task has an estimated completion percentage.

I realise I could treat each tasks completion percentage as a representation of the degree of membership to the fuzzy set "complete tasks" and the incomplete percentage as the degree of memebership to the fuzzy set of "incomplete tasks"

e.g

complete {T1 .80, T2 .73, T3 .0, T4 1.0}

incomplete {T1 .20, T2 .23, T3 1.0, T4 .0}

How would I calculate the degree to which all tasks are complete (sum of all tasks = project so the project completeness) ? ?

Would this be the same as the average task completion e.g. sum(completion) / number of tasks?

N.B not strictly homework, I'm writing the program that handles the projects for an assignment and want to make sure the logic I code is correct.

    I'm not concerned with the tasks, they only have one value, its the total completeness of the project (that is made up of these tasks) I'm interested in determining. I'd like to know if this is the same as the average task completion.2011-11-17

I'd like to know if this is the same as the average task completion Yes, it would be if:

1-The sum of tasks cover the entire project activities in other words, Project = Task1 and Task2 and .... and TaskN

2-The average completion, based on the completion % of each task, is valid indicator only if (1) is true and if all the task have equal weight, otherwise the average may not show the truth.

    Thanks for your comment. Your suggestion of priority may be OK (it depends on your choice). Please check this link it might have some value: http://www.mofeel.net/894-microsoft-public-project/18871.aspx2011-11-18
