north end coffee roasters roast 300bags of coffee per day in three shifts at an average rate of 63 bags/hour. during the first shift, 100bags of coffee are roasted at 63bags/hour and the next 100 bags are roasted at 72 bags/hour in the second shift.
Q- after roasting each bag of coffee is sealed and labelled at the packaging stage at a rate of 90 bags/hour. what is the average rate of production for the entire process pf roasting and packaging coffee beans at north end?
Eakins Enterprises makes model boats, and it is switching to a lean manufacturing process. At one assembly area, Eakins is using one part container that holds 240 parts, and it wants the output to be approximately 80 finished parts per hour; they also desire a 20 percent safety stock for this part. How fast will the container have to make it through the system to accomplish this? Do not round intermediate calculations. Round your answer to two decimal places.

- A manager wants to determine the number of containers to use for incoming parts for a kanban system to be installed next month. The process will have a usage rate of 80 pieces per hour. Because the process is new, the manager has assigned an inefficiency factor of .35. Each container holds 45 pieces, and it takes an average of 75 minutes to complete a cycle. How many containers should be used? As the system improves, will more or fewer containers be required?arrow_forwardFor a particular operation, the setup time is 10 minutes and the run time is 50 minutes to produce a standard lot of 40 parts. It takes three additional hours to circulate a container of parts after production is completed. The demand rate is 20,000 parts per month. There are 160 production hours in a month.a. How many standard containers are needed?b. What is the takt time of this process?arrow_forwardYou have been employed as a junior industrial engineer at a steel manufacturing plant and you have been assigned to be a part of the continuous improvement project team, you are required to report on lean operations Define just-in-time, TPS, and lean operation Elaborate on three issues that are fundamental to the operation improvement Define seven wastes and 5s.arrow_forward
- Assume that a plant operates 2,000 hours per year and the demand rate for parts is 100,000 units per year. The circulation time for each kanban container is 24 hours.a. How many kanban containers are needed for a container size of 100 parts?b. What would be the effect of reducing the container size to 60 parts?c. What is the takt time for this process?d. What takt time is needed for 80,000 units per year?arrow_forwardA JIT system uses kanban cards to authorize movement of incoming parts. In one portion of the system, a work center uses an average of 98 parts per hour while running. The manager has assigned an inefficiency factor of .28 to the center. Standard containers are designed to hold 6 dozen parts each. The cycle time for parts containers is about 105 minutes.arrow_forwardStan Weakly can sort a bin of 130 letters in 20 minutes. He typically receives 550 letters an hour. A truck arrives with more bins every 30 minutes. The office uses a safety factor of 20%. How many kanbans are needed for the letter-sorting process? Please show working. Thank you!arrow_forward
- A JIT system uses kanban cards to authorize movement of incoming parts. In one portion of thesystem, a work center uses an average of 100 parts per hour while running. The manager hasassigned an inefficiency factor of .20 to the center. Standard containers are designed to hold sixdozen parts each. The cycle time for parts containers is about 105 minutes. How many containersare needed?arrow_forwardA company is using a Kanban system with 2 containers, each holding 50 parts, between a downstream (using) and an upstream (producing) work center. The using work center can handle 250 jobs per day. The average elapsed time for the entire cycle is currently .25 days. The company is concerned with the safety factor for the operation and the size of the containers. A: What is the efficiency rating of the current operation? B: If the company decides to use only one container, how many parts must it hold? C: If the safety factor is changed to .12 and there are still 2 containers, how many parts must each container now hold?arrow_forwardExplain the following things related to lean: a) Don't get it, don’t make it and don’t send it b) Five golden rules of Gemba Management c) Jobs per hourarrow_forward
