Fun Vehicles,Inc.,makes "beach buggies" on an assembly line with 11 work elements.Information on these work elements is as follows: \[\begin{array} { | c | c | c | } \hline \begin{array} { c } \text { Work } \\ \text { Element } \end{array} & \text { Time (sec) } & \begin{array} { c } \text { Immediate } \\ \text { Predecessor(s) } \end{array} \\ \hline 1 & 40 & \text { None } \\ 2 & 35 & 1 \\ 3 & 20 & 1 \\ 4 & 25 & 1 \\ 5 & 30 & 2,3 \\ 6 & 35 & 4 \\ 7 & 35 & 5 \\ 8 & 15 & 5,9 \\ 9 & 5 & 6 \\ 10 & 40 & 4,9 \\ 11 & 38 & 7,8,10 \\ \hline \end{array}\] The company wants to re-balance its line to increase the output to two buggies every three minutes.Use the longest work-element time rule to assign tasks to the workstations.Which of the following is the assignment for the first two stations (S1 and S2)produced by this rule? Station Station 1 Tasks 2 Tasks

A) 1, 2 3, 4, 5 B) 1, 2 4, 6, 3, 9 C) 1, 4 3, 2, 5 D) 1, 3, 4 2, 5, 8 A) 1, 2 3, 4, 5 B) 1, 2 4, 6, 3, 9 C) 1, 4 3, 2, 5 D) 1, 3, 4 2, 5, 8

Table 9.5 Union Fork, Inc. has five distribution centers located at the location coordinates given as follows. The demand at each center is also given. \[\begin{array} { | c | c | c | } \hline \text { DC } & \text { Coordinates } & \text { Demand } \\ \hline \text { A } & ( 2,4 ) & 10 \\ \text { B } & ( 6,2 ) & 15 \\ \text { C } & ( 4,10 ) & 25 \\ \text { D } & ( 13,4 ) & 30 \\ \text { E } & ( 10,5 ) & 20 \\ \hline \end{array}\] -Use the information in Table 9.5.If a plant is located at a center of gravity,what is the load-distance score,assuming rectilinear distance?

Table 9.9 The administration department of a small college is now designing its layout for newly built office space. From statistical samplings over the last three months, the following trip matrix was developed for daily trips between departments. Trip Matrix (trips/day) \[\begin{array} { | c | c | c | c | c | c | c | } \hline & \mathrm { A } & \mathrm { B } & \mathrm { C } & \mathrm { D } & \mathrm { E } & \mathrm { F } \\ \hline \mathrm { A } & - & 10 & 75 & & & 140 \\ \mathrm {~B} & & - & & & 95 & \\ \mathrm { C } & & & - & & 130 & 130 \\ \mathrm { D } & & & & - & 10 & \\ \mathrm { E } & & & & & - & 95 \\ \mathrm {~F} & & & & & & - \\ \hline \end{array}\] -Use the information in Table 9.9.If other factors are all equal,which two offices should be located most closely?

A) C and E B) C and F C) E and F D) A and F A) C and E B) C and F C) E and F D) A and F
