IOIIGWufk. Cny Score: 0 of 1 pt Problem 9.18 Assembly Line Balancing 10 of 11 (6 complete) HW Score: 54.55%, 6 of 11 Question Holp The final assembly plant is in Cupertino, California. The assembly area is available for Fig. 1 production of the Mach 10 for 200 minutes per day. (The rest of the time it is busy making other products.) The daily demand is 64 boats. Given the following Time (mins) Predecessors Fig. 2 D, E, F G, H a) The correct precedence relationship with one of the possible assignment of tasks to workstations is shown in Fig. 3Explanation / Answer
Answer a) - the correct figure is figure no. 2
The fig.2 shows the correct network structure for the given workstations.
A gives to B & C. Then C gives D,E & F stations. B gives H station. D,E & F gives G. And finally H& G gives I station.
Answer b) - Operating efficiency of the assembly line using the network as shwon in the figure 2 is as below
Answer c:
Theoritical minimum number of stations = stations in the critical path =5 stations. A-C-E-G-I
Answer d:
The idle time per boat is the longest lead time of the network= lead time of the critical path = 9 minutes.
