1. THE MASTER OF THE GAME LOST (Introduction)

2. GAERMONT COMPANY Gaermont is a company dedicated to producción and marketing of souvenirs and balls.

3. GAERMONT COMPANY Up until now, Gaermont has been a family business, but the enormous growth of the company have made them aware of the need to achieve professional for making logistical decisions.

4. GAERMONT COMPANY For finding this talent, Gaermont has developed a logistic simulator (LOST). In this simulator it has developed a series of challenges that allow participants to grow in the skills for this kind of decisions...

5. THE FACILITIES Although the level of difficulty will be increased gradually, the story has a common scenario... Gaermont has two facilities: A factory where eight different items are produced... A store where they sell these eight products...

6. THE FACILITIES The mean idea is to make a production planning and during the week the factory will produce these goods. Meanwhile, the store will sell the finished products. The factory works from Monday to Friday, and on Saturday they will send the items produced and will do the preventive maintenance to machines.

7. A GRAPHICAL REPRESENTATION

8. THE FINAL SCORE The final score of the game only depends on the utility reached at the end of the year.

9. GUIDELINES Now you have to observe the following guidelines to understand how the game works

10. THE FACTORY The production department has three machines which are used to make eight articles. Furthermore, to make each item you require a certain amount of one or more different raw materials. We will provide you a table describing the number of minutes that each article uses at each machine, as well as the number of grams of different raw materials.

11. THE FACTORY Each of the machines in the factory is operated by a worker. The factory works 16 hours at day from Monday to Friday (two production shifts). This means that it is possible to use each machine a total of 80 hours per week. This time constraint will be extremely important to make your production plan.

12. PRODUCTION DATA Consider the next table Table 1

13. PRODUCTION DATA If you want to perform a production run of 800 units of Product 1 and 200 units of Product 4. You will need: 800 (3) + 200 (6) = 3 600 minutes at the machine 1 800 (5) + 200 (5) = 5 000 minutes at the machine 2 800 (4) + 200 (0) = 3 200 minutes at the machine 3 Note: This production plan is impossible to execute because you outgrow time machine 2 that is 80 hours (4800 minutes).

14. PRODUCTION DATA Now suppose you want to produce 60 units of Product 1 and 30 units of Product 7. Then you will use: 60 ( 40) + 30 (60) = 4 200 grams of raw material A 60 (120) + 30 (80) = 9 600 grams of raw material B 60 ( 80) + 30 (90) = 7 500 grams of raw material C By other hand, every time that you specify the amount of raw material for production, employees take this raw material from the warehouse and the excess raw material is lost. That is, if you intended to this production run 8 kg of A, 10 kg of B and 9 kg of C, you would be wasting materials (you will have a surplus of 3.8 kg of A, 0.4 kg of B, and 1.5 kg of C) and it will increase your production cost.

15. SUPPLIERS DATA Consider the next table TABLA 2

16. SUPPLIERS DATA Suppose that you want to order 800 Kg of Raw Material A to supplier 2, and order 500 Kg of Raw Material C to supplier 3. The cost will be: 800 (42) + 700 + 500 (58) + 1 000 = 64 300

17. GAERMONT COMPANY Moreover, the company has decided that the purity of the material used in the production (quality), must be at least 90. So if you perform a production plan, then you must calculate the weighted purity of materials. To do this, you must be add the product of the quality of the raw material multiplied by the quantity of raw material, and then divide by the quantity of raw material used in the production run. The surplus of raw material will not be considered at this calculus.

18. GAERMONT COMPANY By example, we said before that the quantity of raw material needed for 60 units of Product 1 and 30 units of product 7 is 4.2 Kg de Raw Material A, 9.6 Kg of Raw Material B and 7.5 Kg of Raw Material C. If we intended 4.2 Kg of Raw Material A from Supplier 1; 5 Kg of Raw Material B from Supplier 2; 5 Kg of Raw Material B from Supplier 2; and 8 Kg of Raw Material B from Supplier 3; to this production plan, then the quality will be: [ (4.2) (90) + (5) (96) + (4.6) (91) + (7.5) (97) ] / (4.2 + 9.6 + 7.5) = 94.089 In this calculus is important to note that the weighted quality is calculated only with the quantity of material used in production. Furthermore, in the case of raw material B where two different qualities are used, we use first the raw material with the highest quality.

19. OPERATION COSTS Finally, consider also that the use of the machines generates a cost per hour and employees have a weekly wage.

20. OPERATION COSTS If you decide to produce 800 units of article 1, then you will use 2 400 minutes at machine 1; 4 000 minutes at machine 2; and 3 200 minutes at machine 3 (assuming production times listed in Table 1). This means that you spend operation on two concepts: Wages and Cost of machine operation. The cost of salaries is $ 9,000 (six workers with a salary of $ 1,500 per week). The cost of operating the machines will be: (2400/60) (120) + (4000/60) (150) + (3200/60) (210) = $ 26 000

21. THE STORE Gaermont revenues are generated by the number of items they sell to their customers. To make every decision you'll have a report on the amount of finished product that exists in store. You must consider that if demand is higher than the amount of product available for sale, the excess demand becomes lost sale. For example, suppose that at the beginning of the week you observe that has 228 units Product 1 and 306 units of the product 4. If demand during the week was 102 units of product 1 and 423 units for the product 4, this means that sales of the Product 1 and 4, will be 102 and 306 units, respectively. Income is calculated by multiplying the number of units sold by the selling price of each unit (which appears in Table 1)

22. THE MONEY Each week the program will show a report of the quantity of money that you have at the bank. The bank will pay you an interest rate of 8% anually. YOU WILL NEVER END A WEEK WITH RED NUMBERS. If you do this the game will end.

23. THE TRANSPORT To carry materials from the factory to the store you can use one or more transport units. Each unit can carry 800 units and the cost of renting a unit is $ 1000.

24. THE SCENARIOS During this course your will face three different challenges: SCENARIO 1: THE WORLD OF CERTAINTY SCENARIO 2: REALITY IS STOCHASTIC SCENARIO 3: INCORPORATING DEMAND CURVES

25. THE WORLD OF CERTAINTY Features There is a record of demand Supplier have a fixed lead time No defective products in production There is only one type of transport Decisions Decision 1: How to produce? Decision 2: What quantity of raw material will be used for production? Decision 3: Do you order raw material to suppliers? Decision 4: How many units of transport do you want to use?

26. REALITY IS STOCHASTIC Features There is a record of sales Supplier have stochastics lead time There are defective products in production There is two types of transport Decisions Decision 1: How to produce? Decision 2: What quantity of raw material will be used for production? Decision 3: Do you order raw material to suppliers? Decision 4: How many units of each type of transport do you want to use?

27. INCORPORATING DEMAND CURVES Features There is a record of sales and sales price There is the possibility to work overtime Supplier have stochastics lead time There are defective products in production There is two types of transport Decisions Decision 1: How to produce? Decision 2: What quantity of raw material will be used for production? Decision 3: Do you order raw material to suppliers? Decision 4: Do you want to work overtime? Decision 5: Do you want to change the sales price? Decision 6: How many units of each type of transport do you want to use?
