$2.$ The processing time and precedence information for producing a certain product is given below.

a$)$ Draw the assembly precedence diagram

b$)$ Assign the tasks into a suitable number of stations using the Line of Balance Algorithm. Assume a circle time of $35$ time units.

c$)$ Calculate the balance delay

Note:

Be sure to show details of how you obtained tasks assignments to stations using the line balancing technique under consideration. Simply stating Station $1$ has tasks a$,$ c $\backslash (\backslash$boldsymbol$\{\backslash$&$\}\backslash )$ e for example will result in a penalty on your grade.
