One disadvantage of appointment systems is:

Bottlenecks may shift with the passage of time, so that different operations become bottleneck operations at different times.

A scheduling technique used to achieve an optimum, one-to-one matching of tasks and resources is:

The purpose of cyclical scheduling is to:

For the jobs listed below, which processing sequence would result using Johnson's rule? $\begin{array}{l}\text { Processing time (hrs) }\\\begin{array} { c c c } \hline \text { Job } & \text { Center 1 } & \text { Center 2 } \\\text { a } & 6 & 11 \\\text { b } & 12 & 8 \\\text { c } & 5 & 9 \\\text { d } & 10 & 7\end{array}\end{array}$

Similar to that in manufacturing, the service scheduling hierarchy begins with __________ and ends with _________.

There are three jobs to be done and three resources with which to do them. Each resource will cost a specific amount to do each job, as shown in the following table: $\begin{array} { l c c c } && { \text { Machine } } \\\text { Job } & \text { A } & \text { B } & \text { C } \\\hline 1 & 6 & 9 & 4 \\2 & 4 & 4 & 3 \\3 & 8 & 7 & 4\end{array}$ What is the result of modifying the row and column reductions table?

Job X, which has a duration of four days, is due by the close of business on Friday, December 23. Without looking at the work already at X's required resource, the scheduler schedules X to be begun immediately and assumes that X will be done four days from now. This is an example of:

The term loading, as used in scheduling, refers to choosing the order in which jobs will be processed in low-volume systems.

A major difference between manufacturing and service systems in terms of scheduling is:

The following matrix shows relative costs for various job-machine combinations. Which set of pairs constitutes the minimum-cost solution using the assignment method? $\begin{array}{c} \quad\quad\quad\quad\quad{\text { Machine }} \\\begin{array}{rrrr} & \text { A } & \text { B } & \text { C } \\\text { Job 1 } & \$ 6 & 0 & 0 \\2 & 0 & 3 & 4 \\3 & 0 & 1 & 2\end{array}\end{array}$

There are four resources and four jobs to be done. The time required for each resource to do each job is as follows: $\begin{array} { c } \quad \quad \quad \quad { \text { Job (Hours) } } \\\begin{array} { l c c c c } \text { Resource } & \mathrm { A } & \mathrm { B } & \mathrm { C } & \mathrm { D } \\\hline 1 & 5 & 8 & 7 & 7 \\2 & 4 & 9 & 5 & 9 \\3 & 6 & 9 & 8 & 7 \\4 & 7 & 6 & 6 & 9\end{array}\end{array}$ After the row and column reductions, what is the reduced time for assigning resource 4 to job D?

Refer to the following data for jobs waiting to be processed at a single work center (jobs are shown in order of arrival): $\begin{array} { l c c } \text { Job } & \begin{array} { c } \text { Processing Time } \\( \text { days } )\end{array} & \begin{array} { c } \text { Due Date } \\\text { (days from now) }\end{array} \\\hline \mathrm { A } & 2 & 2 \\\mathrm {~B} & 5 & 6 \\\mathrm { C } & 6 & 10 \\\mathrm { D } & 3 & 4 \\\mathrm { E } & 4 & 8\end{array}$ If jobs A, B, and C require two operations each, while jobs D and E require one operation each, what is the schedule sequence using the slack per operation (S/O) priority rule?

The output of the system cannot exceed the output of the bottleneck operation(s).

Input/output (I/O) control refers to monitoring the productivity changes since productivity is determined by the ratio of output to input.

Using the information in the table, determine the following: (A) Processing sequence using (1) SPT and (2) EDD rules (B) Average completion time and average job tardiness under each rule $\begin{array} { c r r } \text { Job } & \begin{array} { r } \text { Processing } \\\text { Time (days) }\end{array} & \begin{array} { r } \text { Day } \\\text { Due }\end{array} \\\hline \text { A } & 4 & 11 \\\text { B } & 6 & 5 \\\text { C } & 3 & 1 \\\text { D } & 2 & 8 \\\text { E } & 5 & 7\end{array}$

Which of the following is least likely to be a consideration when scheduling a high-volume system?

When orders exceed our capacity, priority rules are used to select which orders will be accepted.
