Analyzing Casino Honey-Handling Processes – Teaching Note
1. Draw a diagram of the drop process. How long should it take to empty 300 silver dollar slot machines? Getting the slot cabinet keys only needs to be done one time and takes 15 minutes. Getting the drop buckets will take 3,000 minutes (300 x 10). To empty 300 slot machines, 15 carts need to be delivered (300/20), and delivering the 15 carts will take 450 minutes (15 x 30). Total time to complete the process will be 15 + 3,000 + 450 = 3,465 minutes. This 57 ¾ hours of work.
This assumes that only 1 team is doing the work.
2. Draw a diagram of the hard count process. How long should this process take to complete for 300 silver dollar slot machines? Assume that each slot machine has an average of 750 silver dollars when it is emptied. Let’s assume that the weigh scale test is ok. This will take 10 minutes. To weigh and record 300 buckets takes 2,100 minutes (300 x 7). An average of 30 rolls need to be wrapped for each bucket processed (750/25). This means that a total of 9,000 rolls will need to be wrapped (30 x 300). At 10 rolls/minute this will take 900 minutes (9,000/10). Rolls are then placed in cans. To can 9,000 rolls 225 cans need to be filled (9000/40). At 5 minutes/can this will take 1,125 minutes. The summary report is then run that takes 5 minutes.
Finally, can counts are manually verified. At 2 minutes/can this will take 450 minutes. The total time to complete the process is
10 + 2,100 + 900 + 1,125 + 5 + 450 = 4,500 minutes or 76.5 hours.
3. The casino is considering the purchase of a second coin-wrapping machine. What impact would this have on the hard count process? Is this the most desirable machine to purchase? Actually, the slowest process that involves a machine is the weighing process. The company should look into a second scale.
