Date: 09/22/98 at 18:05:26 From: Lindsay Subject: Making a time schedule I've figured the first part of the question, but now I have to do the second part. This is it: Jill's customers at the ice cream parlor on Saturday: 11:00am - 12:00pm 98 customers 12:00pm - 1:00pm 120 customers 1:00pm - 2:00pm 101 customers 2:00pm - 3:00pm 86 customers 3:00pm - 4:00pm 50 customers 4:00pm - 5:00pm 42 customers 5:00pm - 6:00pm 56 customers 6:00pm - 7:00pm 87 customers 7:00pm - 8:00pm 143 customers 8:00pm - 9:00pm 132 customers 9:00pm - 10:00pm 86 customers 10:00pm - 11:00pm 78 customers When planning each Saturday's schedule, Jill likes to follow certain guidelines. Using the guidelines listed below, make a time schedule for this Saturday, based on the number of customers Jill had last Saturday. - No person works more than 4 hours in a day. - No person works fewer than 2 hours in a day. - In addition to the servers, there is always 1 person working the cash register each hour. - There is always 1 server for every 30 customers in the store. Jill always rounds up the number of servers needed to the nearest whole number. So, if there are 31 customers in an hour, 2 servers should be working, and so on. Use fictional names or the variables for the employees (for example, Server A, Server B, and so on). Make your schedule easy to read. Be sure to show who will be the cashier each hour.

Here is how I would go about it. First, find out how many servers (plus the cashier) are needed each hour. For example, for the first hour, there should be one cashier and four servers (98 customers need four servers. Do you see why?). The second hour needs one cashier and four servers as well. So I would make up a chart like this: Hour Workers needed 1 5 2 5 3 5 . . . . Once you have this list made up, start another column for workers. For example, if my workers are all named after letters, my third column might be: Hour No. of Workers Workers 1 5 A, B, C, D, E 2 5 A, B, C, D, E 3 5 A, B, C, F, G (D and E end their shifts) 4 4 A, B, F, G (C goes off duty) . . . Just continue in this way, making sure that no one works more than 4 or fewer than 2 hours. Once your list is all done, you'll have to put it into a schedule. There are a lot of ways you could do that. I would probably list the hours, and then who is working during them. Don't forget to delegate someone to the cash register each hour. I hope this helps get you started. If you still have questions about how to write your schedule, don't hesitate to write us back. - Doctor Sonya, The Math Forum http://mathforum.org/dr.math/
