Part $1$

Jane produces custom greeting cards using six distinct work elements. She would like to produce $8$ cards in each$8-$hour card$-$making session. The figure to the right details each work element and its associated durations in minutes as well as their precedence relationships.

Part $2$

a$.$ What cycle time is required to satisfy the required output$$ rate?

$$

$60$minutes$/$card$.($Enter your response as an$$ integer.$)$

Part $3$

b$.$ What is the theoretical minimum number of workstations$$ required?

$$

$2$ stations.$($Enter your response rounded up to the next whole$$ number.$)$

Part $4$

c$.$ If Jane identifies a five$-$station $$solution$,$ what is the associated efficiency and balance$$ delay? $($Enter your responses as percentages rounded to one decimal$$ place.$)$

$$ Efficiency:

$$

$28\mathrm{.}3\%.$

$$Balance$$ delay:

$$

$71\mathrm{.}7\%.$

Part $5$

d$.$ If the cycle time increased by $100$ percent, would the theoretical minimum number of workstations also increase by $100$ percent?

A$.$

$$No$,$ the theoretical minimum number of workstations increases by $200$ percent.

B$.$

$$Yes$,$ the theoretical minimum number of workstations also increases by $100$ percent.

C$.$

$$No$,$ the theoretical minimum number of workstations does not change.

D$.$

$$No$,$ the theoretical minimum number of workstations halves.
