Consider a Project Composed Activities X and Y Having Equal

question 96

Essay

Consider a project composed activities X and Y having equal length and performed in that order. Both activities can be laddered such that the first half of each activity is the predecessor for its own second half, so X1 precedes X2 and Y1 precedes Y2. The first half of X1 is also the predecessor for Y1. If the laddering procedure were performed again activities X and Y would be divided in four parts each, with precedence working as it did in the first split. Derive an expression for the minimum length of the project as laddering increases.
