When a patient enters the Valley Health Clinical Laboratory to have his blood drawn and a Chemistry Panel and CBC run, he spends, on average 2 minutes at patient check-in, 45 minutes in the waiting area, 5 minutes having his medical history updated, and 8 minutes having his blood taken.
If the clinical laboratory has 3 full-time Lab Techs, operates 8 hours per day and demand is 75 patients per day, what is the takt time? Assume that the med techs take a 30 minute lunch.

- A Chocolate manufacturing company produced 180000 bars last year. The company works 3 shifts per day 8 hours shift and operates 250 days per year. The production line is designed to produce 100 bars per hour. The company allocates 0.5 an hour/day for preventive maintenance, 1 hour/ day for employee breaks, and 1.5 hours/day to set up machines for different products. What is the actual outputs? 30 bars per hour 48 bars per hour 60 bars per hour 100 bars per hourarrow_forwardA company that makes a product recently purchased some new equipment that reduces the labor content of the jobs needed to produce the product. Prior to buying the new equipment, the company used six workers, who produced an average of 90 units per hour. Workers receive P35 per hour and machine cost was P2,000 per hour. With the new equipment, it was possible to transfer one of the workers to another department, and equipment cost increased by P500 per hour while output increased by four units per hour. Compute the multifactor productivity under each system. Use units per peso cost (labor plus equipment) as the measure.arrow_forwardA company that makes a product recently purchased some new equipment that reduces the labor content of the jobs needed to produce the product.

One filter, part number JJ39877, is supplied on an exclusive contract basis to Oil Changers at a constant 200 units monthly. Filter Systems can produce this filter at a rate of 50 per hour. Setup time to change the settings on the equipment is 1.5 hours. Worker time (including overhead) is charged at the rate of $55 per hour, and plant idle time during setups is estimated to cost the firm $100 per hour in lost profit.Filter Systems has established a 22 percent annual interest charge for determining holding cost. Each filter costs the company $2.50 to produce; they are sold for $5.50 each to Oil Changers. Assume 6-hour days, 20 working days per month, and 12 months per year for your calculations.a.

- Seaports are important in global supply chains. Their management plays an important part in minimizing waiting time for ships that visit seaports for loading and unloading cargo and port utilization. The Oakland seaport is a busy container seaport on the West coast of America, but it is a bit relaxed in the month of December. Based on the past data, it is observed that 6 ships arrive there, on an average, per day, and it takes 3 hours to unload a ship on an average, with a standard deviation of 4 hours. Determine the following: Minimum number of unlading facilities. Probability (each unloading facility is busy) Probability (each unloading facility is idle) Probability of 2 ships in the system and 4 ships in the system Average number of ships in the system, that is, number of ships in the line including the one being unloaded.

On far too many occasions, customers have not been able to purchase the bread of their choice. Because of the size of the store, no new ovens can be added At a staff meeting, one employee suggested ways to load the ovens differently so that more loaves of bread can be boked at one time. This new process will require that the overs Employees are paid $8 per hour. In addition to the labor cost, Charles also has a constant utility cost per month of $550 and a per loaf ingredient cost of $0.50 loaded by hand, requiring additional manpower. This is the only production change that will be made in order to meet the increased demand.

- The wheat harvesting season in the American Midwest is short, and most farmers deliver their truckloads of wheat to a giant central storage bin within a two-week span. Because of this, wheat-filled trucks waiting to unload and return to the fields have been known to back up for a block at the receiving bin. The central bin is owned cooperatively, and it is to every farmer’s benefit to make the unloading/storage process as efficient as possible. The cost of grain deterioration caused by unloading delays, the cost of truck rental, and idle driver time are significant concerns to the cooperative members. Although farmers have difficulty quantifying crop damage, it is easy to assign a waiting and unloading cost for truck and driver of $18 per hour. The storage bin is open and operated 16 hours per day, 7 days per week, during the harvest season and is capable of unloading 35 trucks per hour according to an exponential distribution. Full trucks arrive all day long (during the hours the bin…arrow_forwardHTeld given below A plant runs in two shifts, one shift of 8 hours and during each shift there is 2 hours of planned downtime. If the machine is stopped each day an average of 110 minutes for setups and 75 minutes for breakdowns and repairs. Determine the availability of machines. Also suppose the average daily throughput of the machine is observed to be 830 units, and the actual cycle time is observed to be 0.6 min/part. Determine the rate efficiency and performance efficiency of machines (Assume speed efficiency = 0.83).
