a manufacturing process consists of three sequential steps. step $1$ has a capacity of $2$ units$/$hour$.$ step $2$ has a capacity of $6$ units$/$hour$.$ step $3$ has a capacity of $1$ unit$/$hour$.$ at each step there is only one resource available. a$)$what is the capacity of this process In units$/$hour$.$explaion your answer. b$)$assuming it is operating at full capacity, what is the utilization in step $1.$ c$)$ assuming it is operating at full capacity, what is the cycle time in minutes. d$)$ suppose the takt time is $45$ minutes. is this process capacity$-$constrained, demand$-$constrained, neither, or both? explain your answer.
