Consider the system with one server per station. What is this system's capacity? What is the cycle time for each order through the entire process flow?

Consider the case of Conrad's Cookie Company, where he and two of his friends (Jared and Jack) are working to make and sell cookies. They have just one oven and can bake up to two dozen cookies at a time. The oven can bake two dozen cookies simultaneously (of similar or different ingredients) or one dozen only. If one dozen is baking in the oven, baking time will not be any different from baking two dozen simultaneously. The sequence of baking steps and respective durations are below. Mixing and Spooning (together) 3 mins/dozen Loading 1 minutte/dozen. Baking 8 mins. baking time for one or two dozens. Cooling 6 minutes Packing 5 mins/dozen cookies Payment (to be done after packing only) 1 minute per order If all orders are 4 dozen cookies, a) What is the best way to assign Conrad and his friends to jobs in order to maximize capacity? Find highest theoretical capacity and bottleneck of the process. b) Once system warms up, is the capacity the same...

A veterinary office with three processes (examination, greeting, and checkout) has two types of customers (boarding and medical). A veterinary office has a demand of 2 boarding customers per hour and 5 medical customers per hour. Boarding customers visit the greeting and checkout processes while medical customers visit all three processes. What is the total demand at the checkout process each hour? customers per hour

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 4 workers, who produced an average of 87 carts per hour. Workers receive 13ドル per hour, and machine coast was 32ドル per hour. With the new equipment, it was possible to transfer one of the workers to another department, and equipment cost increased by 18ドル per hour while output increased by four carts per hour.a) Compute the multifactor productivity (MFP) (labor plus equipment) under the Prior to buying the new equipment. The MFP (carts/$) = ( ) (round to 4 decimal places).b) Compute the % growth in productivity between the Prior to and after buying the new equipment. The growth in productivity = ( ) % (round to 2 decimal places)

Process time is part of cycle time. The process time of a business process refers to: a. alWways is the largest part of cycle time. b. timMe a customer spends waiting in a queue (e.g., time customer spends waiting in a drive-thru line) c. is ofFten considered to be value-added time to the customer. d. timMe from beginning to completion of the business process.

The 4M company has a lathe as the centerpiece of the plant's work. The jobs arrive according to a Poisson process with an average rate of 2 per day. The processing time of each job is exponentially distributed with an average of 1/ 4 day. Since the jobs are large, if they are not in process they are stored in a warehouse some distance from the machine. However, to save time in bringing them in, the production manager proposes to add space for 3 in-process jobs in addition to the one on the lathe (the rest will continue to be stored). With this proposal, what proportion of the time will the space next to the lathe be adequate for the waiting jobs? Calculate your answer using the formulas available.

CPU-on-Demand (CPUD) offers real-time high-performance computing services. CPUD owns 1 supercomputer that can be accessed through the Internet. Their customers send jobs that arrive, on average, every 4 hours. The standard deviation of the interarrival times is 4 hours. Executing each job takes, on average, 3 hours on the supercomputer and the standard deviation of the processing time is 3.6 hours. On average, how long will it take to complete a job (from the time it is submitted by the customer until the time it is completed)?

Mom and Pop own and operate the Fuzzy Belly Deli. On average, customers arrive at the deli every 6 minutes. Pop fulfills their orders one at a time. It takes him an average of 3 minutes to fulfill each order. Customers then proceed to the cash register, where Mom receives their payment. Mom loves to chat and is somewhat slow in operating the cash register, taking an average of 4 minutes to receive payment from each customer. Assume that customer interarrival times, as well as order fulfillment and payment times are exponentially distributed. What is the throughput of the deli's operation? What is the capacity of the deli's operation? On average, how long does a customer spend at the deli from the time she arrives until her order is fulfilled by Pop?

You have started a new business with your friends while you are still a student. You have special clientele.. they like snakes as pets...Hence you start a tea/snake shop (you will serve tea and snakes for entertaining your clients). You decide to hire one server in the beginning. You expect about 15 customers per hour (mean value with Poission distributed arrivals) arriving in the morning hours. The server will take about 4 minutes to serve a customer (mean time). For this situation (Situation A) Find: a. Arrival and service rates b. Find system utilization c. Percentage of time server is idle d. What is wrong with the picture? e. What can you do to help the situation? f. Once you correct the situation (adopt one of the possible solutions), find probability of 5 customers in the system. g. Find the expected number of customers waiting to be served. h. What is the service and weight times (system wait time)? i. Solve the above problem assuming M/M/1 queue discipline. You are now become...

Consider doctor’s office: Physician’s have 30 min appointment slots starting at 8 AM to 6 PM Physicians spend 90 min (1.5 hrs.) each day on electronic medical records and 30 min on claims processing/questions related to medical insurance Typically, physicians have 75 percent appointments booked in advance, which leads to frequent cancellations. One out of 6 patients do not show up Even though appointment slots are 30 min, physicians spend on average 23 minutes with patient. Out of those 23 min, say 5 min could be done by nurse How much of physician’s work is value added

A small call center normally has four employees answering calls while open. On average, seven calls arrive every four minutes. Under normal operating conditions, each employee on average handles each call in 3.3 minutes. But today, one employee has the flu, so the center needs to operate with three employees during this time. The manager is nervous that it may be supply-constrained and so she directs her employees to hurry up their processing of calls today. What is the maximum average processing time for each call that they need to achieve today so that they have a stable queue? Note: Round your answer to 2 decimal places. Answer is complete but not entirely correct. Maximum average processing time 4,73 minutes
