Table 1: Herbal Teas
Each herbal tea is packaged as a box of 20 tea bags for a retail cost of $2.60 per box. While price is the same no matter the variety, the cost of ingredients varies for each herbal tea based on the type and amounts of ingredients in each. Table 2 shows the per-gram cost of each ingredient, and how much of each ingredient is in stock and available for mixing:
Ingredient Name Cost per gram in $ Availability in grams
Hibiscus (HB) $0.05 8000
Chamomile (CH) $0.04 10000
Spearmint (SP) $0.03 10000
Lemon Grass (LG) $0.04 5000

Table 2: Herbal Ingredients
Max Profit
Conditions:
1. For inventory purposes, Celestial Seasonings must produce at least 100 boxes of each variety of herbal tea.
2. The supply of Eleuthero has a limited shelf life, and Celestial Seasonings should use 100% of their available Eleuthero today in production. Each gram of Eleuthero not used today still costs $.07, with no additional profits (count the left over and thrown away Eleuthero in the total cost for the day).
Project Part 1:
A. Set up a Linear Programming model to maximize profit. Identify the objective function and the formulas for all constraints.
B. Run the model, and provide a copy of your answer report.
C. In a summary, identify how many boxes of each tea will be produced (does it make sense to make .73 of a box?) and how much of each ingredient will be left over in inventory.
D. For each type of tea, identify the limiting factor(s) which prevented Celestial Seasonings from making more of that tea.
Project Part 2:
A. Maintenance problems have limited today’s production to exactly 1100 units total. Celestial Seasonings would like to re-run their production model with this limitation in mind, and minimize total costs rather than maximizing profit. Re-run your model and provide a copy of your answer report.
B. In a summary, identify how many boxes of each tea will be produced and how much of each ingredient will be left over in inventory.
Project Part 3:
A. Assume the costs of peppermint and Eleuthero have doubled. Re-run your project Part 2 model (cost minimization) and provide a copy of your answer report. (don’t limit to 1100 units total)
B. In a summary, identify how many boxes of each tea will be produced and how much of each ingredient will be left over in inventory.
Assignment Deliverables:
Create a spreadsheet that helps to answer these questions. Create a tab for each Project Part and produce an answer report within each tab. Clearly answer each question that is part of the project. Most importantly, create a dashboard with instructions on how to use the optimization you have created. It should have instructions on what things you could change (Recipes? Costs? Inventories? Other things?). It should have instructions on how to maximize profits. It should be well organized, well labeled, easy to use, and easy to understand.
