- Example 12.8. A firm uses milling machines, grinding machines and lathes to pro- duce two motor parts. The machining times required for each part, the machining times avail- able on different machines and the profit on each motor part are given below : Machining time reqd. for the motor part Max. time available per Type of machine (mts) week (minutes) I II 10 2,000 Milling machines Grinding machines Lathes. 2 900 12 3,000 Profit/ unit (Rs.) 100 40 Determine the number of parts I and II to be manufactured per week to maximize the profit. د هarrow_forwardAt a small but growing airport, the local airline company is purchasing a new tractor for a tractor-trailer train to bring luggage to and from the airplanes. A new mechanized luggage system will be installed in 3 years, so the tractor will not be needed after that. However, because it will receive heavy use, so that the running and maintenance costs will increase rapidly as the tractor ages, it may still be more economical to replace the tractor after 1 or 2 years. The following table gives the total net discounted cost associated with purchasing a tractor (purchase price minus trade-in allowance, plus running and maintenance costs) at the end of year i and trading it in at the end of year j (where year 0 is now). 1 2 3 $18,000 10,000 $31,000 21,000 $8,000 1 2 12,000 The problem is to determine at what times (if any) the tractor should be replaced to minimize the total cost for the tractors over 3 years. Formulate this problem as a shortest-path problem by drawing a network after you…arrow_forwardProblem 4. Consider the following dynamics. If today is sunny, tomorrow will be sunny with a probability of 0.5, cloudy with a probability of 0.4 and rainy with a probability of 0.1. If today is cloudy, tomorrow will be sunny, cloudy, or rainy, with a probability of 0.5, 0.2, and 0.3, respectively. Lastly, if today is rainy, tomorrow will be sunny, cloudy, or rainy with a probability of 0.7, 0.2, and 0.1, respectively. a) Draw the corresponding Markov Chain. Clearly define your state space, draw the states and transitions, and include the probabilities on each arc. b) Starting on a Sunny day, what is the mean first passage time till a Rainy day. c) Starting on a rainy day, what is the mean recurrence time.arrow_forward
- Problem #3 - S) - PK Inc. manufactures interior and exterior paints from two raw materials, M1 and M2. The following table provides the basic data of the problem: Maximum daily Tons of raw materials per ton of Exterior paint Interior paint availability (tons) Raw material M1 6. 4 24 Raw material M2 1 6. Profit per ton $5,000 $4,000 A market survey indicates that the daily demand for interior paint cannot exceed that for exterior paint by more than 1 ton. Also, the maximum daily demand for interior paint is 2 tons. PK Inc. wants to determine the optimum (best) product mix of interior and exterior paints that maximizes the total daily profit. 5) Formulate and explain the mathematical model for this LP problem, including: a. The Objective Function All the constraints that the solution must satisfy, including nonnegativity. s) Solve the LP problem using the graphical method. b.arrow_forwardNon-Computer Problem: 1. Does having more gun stores in your neighborhood increase the risk of getting shot? Researchers looked at neighborhoods in a (made-up) city and recorded the number of stores that sold guns in a neighborhood and counted the number of deaths by shootings recorded in that neighborhood in a 6 month period. The data are below. Gun Stores Shooting Deaths 3 5 7 2 3 3 4 3 You may use computer software such as Excel to do the calculations for this problem if you wish, but you must show all ntermediate calculati performed. (In other words, you should show all the same work as if you had done the calculations by hand.) It is also fine to do the problem entirely by hand. and indicate the calculations were a. Make a scatterplot of gun stores (X) and deaths by shooting (Y). b. Describe the form of the relationship. Is there a linear pattern? Is the direction of the association positive or negative? c. Calculate the Pearson correlation coefficient. Explain in simple language…arrow_forwardUse the GRAPHICAL METHOD to solve this LP problem.arrow_forward

Three groups of subjects will be used to study the effect of exercise. Group 1 is sedentary, while group 2 walks and group 3 swims for 1 hour a day. Half of each of the three exercise groups will be on a salt-free diet. An additional group of subjects will not exercise or restrict their salt, but will take the standard medication. Use Z for sedentary, W for walker, S for swimmer, Y for salt, N for no salt, M for medication, and F for medication free (a) Show all of the elements of the sample space S.

Assume that each gallon of Deluxe Vanilla uses 2 quarts of milk, 2 quarts of cream, and 3 ounces of vanilla; each gallon of Regular Vanilla uses 3 quarts of milk, 1 quart(s) Chocolate uses 3.5 quarts of milk, 0.5 quarts of cream, and 7 ounces of cacao. Assume also that the shop has on hand 124 gallons of milk, 68 gallons of cream, 23 pounds of vanilla, and 28 pounds of cacao. How many gallons of each type of ice cream should the shop make to use up all of these ingredients? cream, and 2 ounces of vanilla; and each gallon of Deluxe When you setup a system of linear equations to solve this problem, how many variables and how many equations should you have.?
