cookie report
1. Draw a flow chart of the cookie-making process (you can hand-draw and scan).
See the last page.
2. How long (the throughput time) will it take to fill a rush order of 1-dozen cookie? Assume no other cookies are currently in process. Use a Gantt chart to help with the analysis and attach the screen shot of the Gantt chart.
6+2+1+9+5+2+1=26 mins
3.What is the cycle time? How many orders can you fill in a night (4-hour period)? Does your answer depend on the size of the order, 1-dozen, 2-dozen, or 3-dozen?
cycle time=60/6=10mins (Bottleneck is 10mins, 1hour(60mins)/10mins=6. It has a capacity 6 dozen per hour)
1-dozen: The bottleneck is baking, which is total 10mins.The first step washing and mixing, and second step dishing up cookies onto tray take 8mins to start. Removing the cookies and cooling it, and final step packing and accepting payment take 8mins to finish. Total is 8+8=16mins. Assume X be the order. Then, 10X+16=4hours(240mins) X=22.4 Therefore, in the 4 hour period, there will be 22 dozens of cookies can be done.
2-dozen: 6+2*2+1*2+9*2+5+2*2+1=40mins, It means that we can produce 2 dozen of cookie every 40mins. 240/40=6. 6*2=12dozens can be done in 4 hours.
3-dozen: 6+2*3+1*3+5+2*3+1=54mins. It means we can produce 3 dozen every 54mins. 240/54=4.44=4. 4*3=12 dozens can be done in 4 hours.
4.What is the difference in labor (both you and your roommate’s time) per dozen among 1-dozen, 2-dozen, and 3-dozen orders?
1-dozen: Me: Wash+Mix=6mins, 6mins+Dishing up 2mins=8mins
Roommate: Setting the oven1min+packing2mins+accepting payment1min=4mins
Total=8+4=12mins
2-dozen: Me Wash+mix=6mins. Dishing up 2*2=4mins Total=6+4=10mins
Roommate: Setting the oven 1*2=2mins. Packing 2*2=4mins Accepting payment=1min Total=2+4+1=7
Total=17mins, 17/2=8.5mins per dozen
3-dozen: Me:Wash+Mix=6mins. Dishing up=2*3=6mins 6+6=12mins
Roommate:Put cookies in oven and set up 1*3=3mins Packing 2*3=6mins Accepting
