The unit time is .263
You are setting up a new production line for a new type of delivery drones. You observed that the cost for the 10th unit was $6296.33 and the cost for the 80th unit was $4146.15.
a) What is the K for the learning curve model of this production line?
b) What is the s for the learning curve model of this production line?
c) At which unit does its production cost start to be less than $1500?
8. A furniture company just completed a work analysis on the total completion time for dying
process of handmade dining tables. They have concluded that on average the process takes 27
minutes. However they want to incorporate the performance of the workers and allowance time
on this observed value. They think the people they observed was somehow slow, hence they want
to use a performance rate of 0.93 and they also want to allow 10% (allow=0.1) of job time. Based
on these parameters please calculate the normal and standard time estimates for this process.

However they have to bare the slow down in the process for a while due to this transition. They want to estimate when they can reach to the expected performance level based on a 'learning curve' study. For a certain task they have measured a completion time of 137 minutes in the first time an average employee finished the renewed task.

One approach to managing cycle times to improve delivery dependability is to map out the associated activities in a value-added process using a process flow diagram (see diagram in problem þelow). This allows the manager to identify and measure the specific activities so that the management process can be made more effective. The following problem illustrates the use of cycle time analysis. Problem Company X has recently completed an analysis of its primary value-added process. As part of this analysis, the major flows have been mapped such that the process has been broken down into 10 major activities. To better understand the process, the times to complete,each of these activities have been carefully monitored over the past month. The results of this monitoring follow.

- Suad Alwan, the purchasing agent for Dubai Airlines, has determined that the second plane took 18,000 hours to produce. Using an 85% learning curve and a $35-per-hour labor charge, he wants to determine the cost of the six additional planes. Part 2 Time required for the sixth unit = 13900 hours (round your response to the nearest whole number). Part 3 Cost of the sixth unit = 486500 dollars (round your response to the nearest whole number). Part 4 Time required for the seventh unit = enter your response here hours (round your response to the nearest whole number). Part 5.

How long do you estimate the time required to install the fourth pool?arrow_forwardA call centre that handles customer service telephone calls is monitored by information system that collects data on the number of calls each representative received and the length of time each representative took to answer each call and then to respond to the question or request for service. Managers at the call centre can easily obtain statistics on virtually any part of the process. And data collection is built into the system, making it unintrusive. Obviously, the manager‟s goal is to make sure all calls are answered quickly and that customers are satisfied. Information from the system can then be used in a variety of ways. For instance, a manager can use the information from the system to compare a worker‟s output to that of his colleagues, to his own earlier output, to historical outputs reflecting similar work conditions at other times. He can evaluate the number and duration of calls service representatives answer on a given day. 3. What uses of the…arrow_forward
