Answer the following question
Sensuality Corporation's management keeps track of the time it takes to process orders. During the most recent month, the following average times were recorded per order. Days Wait time 15. 6 Inspection time 0.8 Process time 1.6 Move time 0.7 Queue time 3.9 Required: A. Compute the delivery cycle time in days B. Compute the Percentage of manufacturing cycle time spent on non-value-added activities
Which of the following most directly expresses the motivation behind the expression "Do not block the bottleneck"? Multiple Choice O O O If the bottleneck has nothing to work on, the overall capacity of the process will be lower than it could be. If the bottleneck is prevented from working (e.g., it has nowhere to put its output), the overall capacity will be reduced. Blocking the bottleneck will increase the coefficient of variations of the arrival process, which decreases capacity. Blocking the bottleneck increases inventory turns, which increases the annual holding costs. It is not good to block the bottleneck because there are economies of scale in inventory management.
You operate a process with three workstations; the cycle times are given below. A regular batch is 52 units and your production line runs 5 hours per day. Calculate how many hours lead time is required to ship a batch, assuming there are no orders ahead in the queue and there is no inventory to fill the order. Workstation 1 has a cycle time of 2 minutes per unit Workstation 2 has a cycle time of 3 minutes per unit Workstation 3 has a cycle time of 3 minutes per unit Select one: a. 1560.00 b. 8.00 c. 1560.00 d. 90.00 e. 2340.00
An output of 720 units per shift (7.40 hours) is desired for a new processing system. The system requires product to pass through four stations where the work content at each station is 26 seconds. What is the required cycle time for such a system? How efficient is your system with the cycle time calculated? Station 3 changes and now requires 50 seconds to complete. What will need to be done to meet demand (assume only 7.40 hours are available)? What is the efficiency of the new system?

. In the welding operations of a bicycle manufacturer, a bike frame has a flow time of about 11.5 hours. The time in the welding operation is spent as follows: 2 hours waiting in front of the cutting machine for the batch to start, 2 hours waiting for the setupof the machine, 1 hour waiting for the other pieces of the batch to go through cutting, 1 minute at the cutting machine, and 3 hours waiting for the transfer to the welding machine. Then, at the welding machine, the unit spends 1 hour waiting in front of the welding machine for the batch to start, 1 hour waiting for the setup of the welding machine, 0.5 hour waiting for the other pieces of the batch to go through welding, 0.5 minute at the welding machine, and 1 hour waiting for the transfer to the next department. Determine the exact flow time. What is the value-added percentage of the flow time?
A process has 10 resources and two types of flow units. How many columns will therebe in the demand matrix?a. 2b. 5c. 10d. 20
Lou operates a cab service specifically tailored to provide safe and comfortable transportation for seniors in his town. He owns five cabs, each staffed by a dedicated driver. Upon receiving a service call, Lou promptly dispatches one of these drivers to pick up the customer. The operational details are as follows: • Each driver takes an average of 15 minutes to arrive at the customer's location after being dispatched. • The journey from the customer's pickup location to their destination averages 25 minutes. • Lou’s service receives an average of 2.5 calls per hour. For analytical purposes, you can assume that both the arrival of service calls (demand) and the service times have coefficients of variation (CV) equal to 1. (a) What is the average waiting time for a customer from the moment they place a service call to Lou until a cab arrives to pick them up? (For answering this question carefully think about different stages of processes, and what a customer is doing in each stage. It…
