The owner of Chips etc. produces two kinds of chips: lime(L) and vinegar(V). He has a limited amount of the three ingredients used to produce these chips available for his next production run: 4800 ounces of salt, 9600 ounces of flour, and 2000 ounces of herbs. A bag of lime chips requires 2 ounces of salt, 6 ounces of flour, and 1 ounce of herbs to produce, while a bag of vinegar chips requires 3 ounces of salt, 8 ounces of flour, and 2 ounces of herbs. Profits for a bag of lime chips are $0.40, and for a bag of vinegar chips are $0.50. What is theformulation for this problem?

MAX Z = 0.4L + 0.5Vs.t. 2L + 3V ≤ 4800 6L + 8V ≤ 9600 1L + 2V ≤ 200

_____ simulation is limited because of the amount of real time required to simulate even one

Manual

Let xij = gallons of component i used in gasoline j. Assume that we have four components and four types of gasoline. There are 7000 gallons of component 1 available, and the demand gasoline types 1, 2, 3 and 4 are 8,500, 11,000, 12,000and 14,000 gallons, respectively. Write the supply constraint for component 1.

X11 + X12 + X13 + X14 ≤ 7000

Burglar John infiltrated a house. Unfortunately, he has a relatively small backpack which helps him to carry at most 40 lbs. Possessing a discriminating eye, he can immediately determine how much the items worth. There are 5 different items available. His aim is to maximize the dollar value of the stuff carried away, the overall weight being less than the weight he can carry by using his backpack. Weight and value of each item is given in the following table.

item 5
