Example $2.$

Given three machines $($activities$)$ labeled $1,2$&$3,$

Assume Product B is twice as "difficult" to move as $A$ or $C=>h_{\text{i}\text{j}\text{B}}=2$ and $h_{\text{i}\text{j}\text{A}}=h_{\text{i}\text{j}\text{C}}=1$

a$)$ Calculate flow dominance of this process.

b$)$ Suggest the layout type for this case study.
