Excel spreadsheet with risk solver
Excel sheet, check the two files attached as one for data and one for the problem.
Greater Ware Clothing, Inc. manufacturers and sells shirts and other apparel to retailers in the local area.
Orders have been received and Greater Ware is interested in planning shirt production over the next two
months. The following information has been gleaned from conversations with plant management:
At the beginning of month one, there are 75 shirts in inventory. Retailers have placed orders for 1300
shirts in month one and 1250 shirts in month two. Management insists that these orders are filled. Each
shirt delivered to a retailer brings in $12.75 in revenue. Management has requested that at least 50 shirts
be kept in ending inventory due to sudden changes that can occur in ordering.
To make each shirt, 2.1 square yards of cloth are needed. There are currently 100 square yards of cloth in
inventory. Up to 2800 square yards of cloth can be purchased each month for a cost of $2.55 and $2.70
per yard in month 1 and month 2 respectively. Cloth that is not used in one month can be stored and used
in subsequent months.
Each shirt requires 30 minutes of labor time to produce. Current employment is expected to allow for up
to 670 hours of labor in month one and 700 hours in month two. These figures cannot be altered by hiring CLICK HERE TO GET MORE ON THIS PAPER.....
more employees. The cost per hour for labor is $9.30.
! All numbers above are available in an Excel data file.
! Your submission must include a properly documented and working copy of your model (your Excel
spreadsheet and Solver model) with annotations as needed to explain unclear calculations.
! This is a linear model. If your model requires a different engine, then you need to rethink your
approach to the model. Remember, there are no IF, Max, or MIN statements (or other disjointed
functions) in linear models.

worksheet tab to the right with your mouse, creating a new worksheet tab. Delete any range names on
this tab by accessing the Formulas | Name Manager menu option. On this new tab, model and analyze the
following modification to the original situation:
Aggressive sales by company representatives have generated additional demand. Demands figures for
month one and two are now 1600 and 1750 shirts respectively. It is no longer possible to fill all
demand orders each month. Modify your model (this will require additional decision cells to allow
for the company to sell less than demand). Note that demand not filled in one month does not transfer
to subsequent months (this will make things much easier). What are the apparent limiting resource
constraints in your solution and in which period do they occur?
