Help me out with question 9.17 a b c d

*9.16 The Mach 10 is a one-person sailboat manufactured 9 Tailwind, Inc., produces high-quality but expensive by Creative Leisure. The final assembly plant is in Cupertino, training shoes for runners. The Tailwind shoe, which sells for California. The assembly area is available for production of the $210, contains both gas- and liquid-filled compartments to proMach 10 for 200 minutes per day. (The rest of the time it is busy vide more stability and better protection against knee, foot, and making other products.) The daily demand is 60 boats. Given the back injuries. Manufacturing the shoes requires 10 separate tasks. information in the following table, There are 400 minutes available for manufacturing the shoes in 424 PART 2 DESIGNING OPERATIONS the plant each day. Daily demand is 60 . The information for the g ) What is the best work station assignment you can make tasks is as follows: without exceeding a 10-minute cycle time and what is its efficiency? Px W9.19 Suppose production requirements in Solved Problem 9.2 (see page 419) increase and require a reduction in cycle time from 8 minutes to 7 minutes. Balance the line once again, using the new cycle time. Note that it is not possible to combine task times so as to group tasks into the minimum number of workstations. This condition occurs in actual balancing problems fairly often. PX * 9.20 Because of the expected high demand for Mach 10, Creative Leisure has decided to increase manufacturing time available to produce the Mach 10 (see Problem 9.16). a) If demand remained the same but 300 minutes were available each day on the assembly line, how many workstations would be needed? b) What would be the efficiency of the new system, using the a) Draw the precedence diagram. actual number of workstations from (a)? b) Assign tasks to the minimum feasible number of workstations c) What would be the impact on the system if 400 minutes were according to the "ranked positioned weight" decision rule. available?
