Q$4\mathrm{.}2($Algo$)$ Assign tasks to workers $[4\mathrm{.}1,4\mathrm{.}4]$ Consider the following six tasks that must be assigned to four workers on a conveyor$-$paced assembly line $($i$.$e$.,$ a machine$-$paced line flow$).$ Each worker must perform at least one task. What is the capacity of the current line? Now assume that tasks are allocated to maximize capacity of the line, subject to the conditions that $(1)$ a worker can perform at most two adjacent operations and $(2)$ all tasks need to be done in their numerical order. What is the capacity of this line now?
