1. Resource leveling involves analyzing resource usage and adjusting non-critical activities to reduce overallocation of resources. 2. The document describes calculating an Improvement Factor (IF) for non-critical activities to determine which activities can be moved to reduce resource usage. 3. The example applies the IF calculation to various activities in a project network to level resources, moving Activity G first to reduce the resource usage in period 5 from 9 to 5.

5. 3) Appling the Improvement Factor to non critical activity
IF (A,N)= R ×(𝑹 𝒗 − 𝑹 𝑶 − 𝑹 × (𝑵 𝒓))
A : Activity Name
N : NO of free float days consumed
R : No of resources days used by the activity
𝑹 𝒗 : sum number of resource in days that will be vacated when activity move
𝑹 𝒐 : sum number of resource in days that will be occupied when activity move
𝑵 𝒓 : smaller
The No. of free float consumed
Duration of the activity

IF (I,1)= 4 ×(𝟏𝟏 − 𝟒 − 𝟒 × (𝟏)) = 12
IF (I,2)= 4 ×(𝟏𝟗 − 𝟕 − 𝟒 × (𝟐)) = 𝟏𝟔

IF (F,3)= 2 ×(9−𝟐 − 𝟐 × (𝟏)) = 𝟏𝟎
So we decide to move G first
