Melissa's Photo Studio offers both individual and group portrait options. The process flow diagram below shows that all customers must first register and then pay at one of two
cashiers. Then depending on if they want a single or group portrait they go to different rooms. Finally everyone picks up their own finished portrait.

An automated car wash serves customers with the following serial process: pre-treat,wash, rinse, wax, hand dry. Each of these steps is performed by a dedicated machineexcept for the hand-dry step, which is performed manually on each car by one of threeworkers. The steps of the process have the following processing times:• Pre-treat: 1 minute per car• Wash: 5 minutes per car• Rinse: 2 minutes per car• Wax: 3 minutes per car• Hand dry: 8 minutes per cara. If the car wash has a demand of 15 cars per hour, what is the flow rate of the process?b. If the car wash has a demand of 15 cars per hour, what is the utilization of the machinethat performs the wax process?
What are the steps that the single baseline processing software follows?

- A catalog order-filling process can be described as follows:12 Telephone orders are taken over a 12-hour period each day. Orders are collected from each person at the end of the day and checked for errors by the supervisor of the phone department, usually the following morning. The supervisor does not send each one-day batch of orders to the data processing department until after 1:00 p.m. In the next step—data processing—orders are invoiced in the one-day batches. Then they are printed and matched back to the original orders. At this point, if the order is from a new customer, it is sent to the person who did the customer verification and setup of new customer accounts. This process must be completed before the order can be invoiced. The next step—order verification and proofreading—occurs after invoicing is completed. The orders, with invoices attached, are given to a person who verifies that all required information is present and correct to permit typesetting. If the verifier has…arrow_forwardWhat is flow processing, and what are its advantages and disadvantages?arrow_forwardCan you show me how to do this review problem with steps?arrow_forward
- (Atlas Inc.) Atlas Inc. is a toy bicycle manufacturing company producing a five-inch small version of the bike that Lance Armstrong rode to win his first Tour de France. The assembly line at Atlas Inc. consists of seven work stations, each performing a single step. Stations and processing times are summarized here: Step 1 (30 sec.): The plastic tube for the frame is cut to size. Step 2 (20 sec.): The tube is put together. Step 3 (35 sec.): The frame is glued together Step 4 (25 sec.): The frame is cleaned. Step 5 (30 sec.): Paint is sprayed onto the frame. Step 6 (45 sec.): Wheels are assembled. Step 7 (40 sec.): All other parts are assembled to the frame. Under the current process layout, workers are allocated to the stations as shown here: Worker 1: Steps 1, 2 Worker 2: Steps 3, 4 Worker 3: Step 5 Worker 4: Step 6 Worker 5: Step 7 a.

Given the following description, flowchart the new policy setup process as it existed in 1970: Individual customers who wanted to set up a new policy would visit one of ABC's 70 branch offices or make contact with an agent. They would then fill out an application and sometimes attach a check. The branch office then sent the application package through company mail to the XYZ division in London. In addition, a customer might also fill out the application at home and send it directly to any number of ABC locations, which would then transfer it to the London operation. Once received, XYZ separated the various parts of the application, then scanned and digitized it. The electronic image was then retrieved from a server and delivered to an associate's desktop client computer. The associate was responsible for entering the information on the form into the appropriate database.…arrow_forwardplease help me quickly I will vote your answer with high rate and likearrow_forward

- What is intermittent processing and when is it used? Contrast it with flow processingarrow_forwardThe following flow chart shows the entire manufacturing process at KD Manufacturing, which consists of six independent operations processes (i.e. sawing, sanding, drilling, reshaping, welding, and assembly). The entire process flow starts with the input of three different parts, Part I, Part II and Part III, each entering a different input line. Three parts meet later for the welding, whichever welding station is available (two identical welding stations work independently). After welding is completed, the product is sent to one of the three assembly stations (which are in parallel). The chart also shows the processing time per unit (in minutes) for each operation. Each of sawing, sanding, drilling and reshaping stations is handled by a different worker. Two workers handle welding, each at one welding station. Another three workers handle the assembly process independently, one at each assembly station. To improve the capacity of the entire manufacturing process, the manager decides to…arrow_forwardSmooth Chin Device Company The Smooth Chin Device Company is a manufacturer of high-end electric razors. These razors are produced using a machine-paced process. For each razor, a tray with components enters the process at the beginning of a conveyor belt. The tray then passes through the six steps (consisting of various tasks) explained in the table below. Workers perform the assembly operations on the moving tray. The last step consists of an inspection of the then fully assembled razor. The activity times of the process are as follows: There are six workers, one at each of the six stations (A-F). They begin their workday at 8:00 a.m. and work steadily until 4:00 pm. (They are replaced with other workers for breaks and lunches, but the production is not slowed or stopped during these times.) Their hourly wage rate is $25 per hour. You can assume unlimited demand. What is the process capacity (you can ignore any start-up or empty system effects), in razors/hour?arrow_forward
