Safe BC is a small company that produces security devices and safes. There are many designs for the safes that the company produces. The demand for their safes has been increased recently and the production facility has been enlarged to accommodate the change. The production manager of the company, Betty Westwood has obtained the following table from the sales and marketing department on the projected weekly demand for each model of their safes:

Using the demand data, Betty wants to prepare a production plan for each day of a week. The production department works five days a week. The engineering department has helped Betty to determine the best sequence foreach cycle to be S7-S8-S9-S1-S2. Note that partially completed safes are not permitted and they must produce finished units in each cycle. Determine the level-mix model sequence for this each day.
