Using PERT, We Have Determined the Mean Completion Time for Each

question 10

Essay

Using PERT, we have determined the mean completion time for each activity ( $\mu$ _j) and the standard deviation for each activity completion time ( $\sigma$ _j).How do we use these data to determine the overall project completion time?

Definitions:

pKa

A quantitative measure of the strength of an acid in solution, being the negative log of the acid dissociation constant (Ka).

Tropylium Ion

A positively charged ion (cyclic cation) with the formula C7H7+, known for its aromatic stability.

Planar Molecule

A planar molecule is a molecule in which all atoms reside in the same geometric plane, often associated with molecules containing double bonds that lead to a flat molecular geometry.

Nonaromatic

Refers to compounds that do not possess a ring structure with alternating single and double bonds, lacking the characteristic stability of aromatic systems.
