- A Printed Circuit Board (PCB) machine installs integrated circuits onto a board. Before starting to produce a board, the PCB machine requires a 16-minute setup. Once in production, the PCB machine requires only 0.19 minute per board. a. Currently, the PCB machine produces 525 boards between setups. Given this operating process, what is the capacity of the PCB machine (in boards per min)? b. Currently, the PCB machine produces 525 boards between setups. Given this operating process, what is the utilization of the PCB machine? c. Say the PCB machine produces 400 boards s between setups and demand is 2 boards per minute. Given the operating process, what is the avergae inventory of boards anf the PCB machine? d. Demand for boards occurs at the rate of 2 boards per minute. What is the smallest batch size such that the PCB machine does not constrain the flow rate through the process?A taxi charges P1.50 for the first 300 meters and P1 for every 200 meters thereafter. Any distance covering the next 200-meter zone is still charged P1. Make a flowchart and a C program that would input the DISTANCE a trip took and output the FEE.During a typical Friday, the West End Donut Shop serves 2400 customers duringthe 10 hours it is open. A customer spends, on average, 5 minutes in the shop. On average,how many customers are in the shop simultaneously?
- On a typical Saturday, Red Lobster serves 1,000customers. The restaurant is open for 12 hours. On average,150 customers are present. How long does an averagecustomer spend in the restaurant?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 five workers, who produced an average of 80 carts per hour. Workers receive $10 per hour, and machine cost was $40 per hour. With the new equipment, it was possible to transfer one of the workers to another department, and equipment cost increased by $10 per hour while output increased by four carts per hour. Compute labor productivity under each system. Use carts per worker per hour as the measure of labor productivity. Compute the multifactor productivity under each system. Use carts per dollar cost (labor plus equipment) as the measure.A small mail order firm Seas Beginnings has one phoneline. An average of 60 people per hour call in orders, and ittakes an average of 1 minute to handle a call. Time between calls and time to handle calls are exponentially distributed.If the phone line is busy, Seas Beginnings can put up toc 1 people on hold. If c 1 people are on hold, a callergets a busy signal and calls a competitor (Air End). SeasBeginnings wants only 1% of all callers to get a busy signal. How many people should the company be able to put onhold?
- The magnetic resonance imaging (MRI) unit of St Francis hospital has 2 MRI machines and sees two kinds of patients, "regular" patients and "contrast" patients. The regular patients don't need any special preparation before imaging but the contrast patients receive an injection of "dye" that enables the physicians to see the images more clearly. Regular patients require 15 minutes in an MRI machine whereas contrast patients take on average 25 minutes in an MRI machine. Over an 8-hour day, the MRI unit receives an average of 25 regular patients and 5 contrast patients. (a) What is the implied utilization (as a %) of the MRI unit? % (b) What are the actual and maximum flow rates through the MRI (patients per day)? regular contrast Actual flow rates Max flow rates.The magnetic resonance imaging (MRI) unit of St Francis hospital has 2 MRI machines and sees two kinds of patients, “regular” patients and “contrast” patients.

- A Printed Circuit Board (PCB) machine installs integrated circuits onto a board. Before starting to produce a board, the PCB machine requires a 20-minute setup. Once in production, the PCB machine requires only 0.15 minute per board. Assume there is ample demand. Currently, the PCB machine produces 500 boards between setups. Given this operating process, what is the capacity of the PCB machine (in boards per minutes)? answer:_________boards per minuteA furnace repair team that services an average of four furnaces a day if the design capacity is six furnaces a day and the effective capacity is five furnaces a day.There is a manufacturing company that has a dedicated production line to make one specific product. The line has three stations working in serial. Inputs arrive at station 1 and the output from station 1 becomes the input to station 2. The output from station 2 is the input to station 3. The output from station 3 is the finished product. Station 1 can process 500 units per week, station 2 can process 300 units per week, and station 3 can process 400 units per week. illustrates this problem. Question Answer ↓ What is the maximum output number per week?
