Carlos Torres' company wants to establish an assembly line to manufacture its new product, the iStar phone. Carlos' goal is to produce 60 iStars per hour. Tasks, task times, and immediate predecessors are as follows: Fig. 1 WS1 Q WS3 Task B WS2 A B DWS4 H EWS5 CDE Performance Time (seconds) IO WS6 50 35 52 40 6 a) The theoretical minimum number of workstations that Carlos can achieve in the assembly line = 6 (round your response to the immediate higher whole number).

Carlos Torres' company wants to estoblish an assembly line to manufacture its new product, the istar phone. Carlos' gaal is to produce 60 istars per hour. Tasks, task times, and immediate predecessors are as follows: a) The theoretical minimum number of workstations that Carlos can achieve in tre assembly line =6 (round your response to the inmedate higher whole number). b) The correct precedence rolationship with a possible assembly line developed using the most following tasks heurstic (fo break a se, assign the iongest task fint) for the istar phone is shown in Fig 2 c) The actual number of workstations used by Carios in desoning the assembly line in (b) for the istar phone =6 (onter your response as a whole number). d) The operating efticiency of the assembly line in (b) = K (enfer your response es a percentage rounded to two decimal places)
