Conceptual Question 18-1 Which of the following performance measures... 2 Which of the following performance measures depend(s) on how work is sequenced at a resource? points Only inventory Only flow rate Only flow time Inventory and flow rate Inventory and flow time @ Flow rate and flow time Conceptual Question 18-14 The theory of constraints is most applicable... 2 The theory of constraints is most applicable in which of the following processes? points An auto repair shop with one mechanic A chemical processing plant with numerous pieces of equipment with significant setup times and a large number of product each requiring different sequences of resources to be completed @ A well-balanced assembly line that makes lawnmowers Conceptual Question 15-5 A company has an unbiased forecast for its... 2 A company has an unbiased forecast for its demand. What does that mean? points All forecast errors are equal to zero. All forecast errors are less than 1 percent. The average of all forecast errors is zero. @ The standard deviation of forecast errors is zero.
Conceptual Question 15-1 When creating a time series—based forecast... 2 When creating a time series—based forecast for the amount of soda to be sold in the cafeteria next week, which data sources can yc points include in your forecasting process? The opinion of the principal Old demand data @ Data about upcoming sports events The age of the cafeteria worker Conceptual Question 18-10 Jobs have different processing times and due... 2 Jobs have different processing times and due dates. If a job is finished earlier than its due date but one day sooner than expected, points how does this change the job’s tardiness? Tardiness decreases by one day. Tardiness does not change. @ Tardiness increases by one day. It is not possible to determine the impact on the tardiness of the job with the given information. Conceptual Question 15-4 What is the definition of a forecast... 2 What is the definition of a forecast error? points The average difference between the actual outcome and the forecast The maximum difference between the actual outcome and the forecast The difference between the actual outcome and the forecast @ The percentage difference between the actual outcome and the forecast
Conceptual Question 15-7 The intuition behind the MAE metric to... 2 The intuition behind the MAE metric to evaluate old forecasts is points to sum up the forecast errors. to sum up the squared forecast errors. to sum up the absolute values of the forecast errors. to average the squared forecast errors. to average the absolute values of the forecast errors. @ Conceptual Question 15-6 The intuition behind the MSE metric to... 2 The intuition behind the MSE metric to evaluate old forecasts is points to sum up the forecast errors. to sum up the squared forecast errors. to sum up the absolute values of the forecast errors. to average the squared forecast errors. @ to average the absolute values of the forecast errors.

Conceptual Question 18-13 Why does the theory of constraints... 2 Why does the theory of constraints advocate that a manager’s attention be directed to the bottleneck of a process? points It is useful to lower the utilization of the bottleneck. The bottleneck has considerable influence on the average flow rate of a process. @ It is important to minimize the buffer inventory in front of the bottleneck. First-come-first-served scheduling of jobs at the bottleneck ensures that all jobs have the same expected waiting time befor they are processed at the bottleneck. Conceptual Question 18-16 Which of the following is a benefit... 2 Which of the following is a benefit of overbooking a resource? points It helps to reduce the average number of jobs waiting to be processed on the resource. It helps to reduce the average flow time of jobs through a resource. It helps to increase the utilization of the resource. @ It helps to reduce the processing times of jobs at a resource.
