Joan has a small design and tailoring shop making custom outfits for women. She has two employees. Each employee only begins working on a dress when a customer order hasbeen received and then she makes the dress from beginning to end. The average production time of a dress is 1.8 days, with a standard deviation of 2.1 days. Historically, Joan hasbeen receiving orders with interarrival times of one day on average. The interarrival times of orders have a coefficient of variation of one.(Carry at least 4 decimal places in all intermediate calculations. Round your final answer to 2 decimal places.)What is the expected waiting time, in days, between when an order is received and when production begins on the dress?A. 9.12 days B. 6.50 days C. 1.23 days D.3.41 days

In order to evaluate and enhance the effectiveness and performance of systems containing waiting…

Suppose i am going to build a digital model for all 4 different products coming to awarehouse. All products first move to a temporary waiting area and then to inspectionmachines. There are 4 inspection machines to process each product respectively. Afterinspection, all products must move to next station for scanning before they are finallytransported to 4 racks.Products arrives exponentially with an average of 12 seconds. Processing times of inspectionmachines ars exponentially distributed with an average 6 seconds. Scanning time is fixed 4seconds.Simulation time is 50000s, Queue capacity is 10000.Suppose i need to redesign this process. How would it be possible to improve this system.Maybe identify the bottleneck by output analysis and propose improvement solution byadding additional object(s) or new automated resource to the original model will be possible?
Johnson Fastener and Tool had a six-hour work stoppage yesterday, which means the company does not have its usual number of fasteners stored in inventory. Concerned that the inability to fulfill all current orders may have an adverse effect on some customers, Acme's account executives are notifying all customers, including Henderson Air, that there could potentially be a small delay in delivering some orders. This is an example of:
Two methods are used to predict how many customers will call in for help in the next four days. The first method predicts the numbers of callers to be 23, 5, 14, and 20 for the four respective days. The second method predicts 20, 13, 14, and 20 for the four respective days. The actual numbers of callers turn out to be 23, 10, 15, and 19. Which method has the smaller mean absolute error (MAE)? Multiple Choice The first method The second method Cannot be determined Both methods have the same MAE
An average of 1200 parts arrive to the EP chamber during an 8-hour workday. Each part goes through two stages of processing. At each stage, a single product is processed at a time, and processing takes an average of 15 seconds at the first station and 12 seconds at the second station. Inter-arrival times and service times are exponentially distributed. At the end of the second step, the product goes through a quality check. 5% of the parts fail the quality check and are sent back to the second stage of service. Parts exit the system only after they pass the quality check. Ignoring the time required to perform the quality check or in moving the part through the facility, what is the average cycle time for parts?
Ashley’s department store in Kansas City maintains a successful catalog sales department in which four clerk takes orders by telephone. If four clerks are occupied on four-lines, incoming phone calls to the catalog department are answered automatically by a recording machine and asked to wait. As soon as the clerk is free, the party that has waited for the longest is transferred and answered first. Calls come in an average of 3 minutes. The clerk is capable of taking an order in an average of 10 minutes. Calls tend to follow a Poisson distribution, and service times tend to be exponential. a. λ= μ= b. Calculate P0 c. How many callers, on average, are waiting to place an order under the current operating system?
A company that makes shopping carts for supermarkets and other stores recently purchased some new equipment that reduces the labor content of the jobs needed to produce the shopping carts. Prior to buying the new equipment, the company used 6 workers, who together produced an average of 70 carts per hour. Workers receive $18 per hour, and machine cost was $30 per hour. With the new equipment, it was possible to transfer one of the workers to another department, and equipment cost increased by $11 per hour, while output increased by 5 carts per hour. a. Compute labor productivity under each system. Use carts per worker per hour as the measure of labor productivity. (Round your answers to 3 decimal places.) b. Compute the multifactor productivity under each system. Use carts per dollar cost (labor plus equipment) as the measure. (Round your answers to 3 decimal places.) c. Comment on the changes in productivity according to the two measures. (Round your intermediate calculations…

A recurring maintenance job in a factory is being done by a three-man crew. Due to the nature of the job and space limitations, it was observed that two of the men were idle 37% of the time; one of the men was also idle an additional of the time, and at any given time only one man was required. The men were each paid P24.00 per hour. Each time the job was performed a set of tools and equipment with a value equivalent to P36.00 per hour was used. If the three-men crew could complete the work in 5 hours, which crew size would be the most economical
