Academic Year: 2011 Semester: II
Subject: Operations Research Code: IT 323
Duration: three Hours Max.Marks:60


1. a) describe Generalized linear programming issue. Old hens can be bought for Rs.2.00 every but young ones cost Rs.5.00 every. The old hens can lay three eggs per week and the young ones, five eggs per week, every being worth of 30 paise. A hen costs Re.1.00 per week to feed. If I have only Rs.80.00 to spend for hens, how many of every type should I buy to provide a profit of more than Rs.6.00 per week, assuming that I cannot house more than 20 hens? Write a mathematical model for the issue. (2 + 4)Marks
b) Solve the subsequent LPP graphically :Maximize Z = 50X1 + 60X2, subject to the constraints 2X1 + 3X2 = 1500, 3X1 + 2X2 = 1500, 0 =X1 = 400, and 0 =X2 = 400. six Marks
2. Solve the LPP by using Simplex method: Maximize Z = 3X1 + 2X2 + 5X3 subject to the constraints X1 + 2X2 + X3 = 430, 3X1 + 2X3 = 460, X1 + 4X2 = 420, and X1=0, X2=0. 12 Marks


3. a) provide Mathematical formulation of transportation issue. 4Marks
b) obtain the optimum (minimum) solution to the subsequent transportation issue through Vogels Approximation method 8Marks

5. a) dhowtoexamuss clearly the different costs that are involved in inventory issues with suitable examples. 6Marks
b) The demand for an item in a company is 18,000 units per year and the company can produce the item at a rate of 3,000 units per month. The cost of 1 set up is Rs.500.00, holding cost of 1 unit per month is 15 paise, and the shortage cost is Rs.20.00 per month, per unit item. Then determine the following: (i) optimum production batch volume and the number of shortages. (ii) optimum cycle time and production time. (iii) maximum inventory level in the cycle. (iv) the total associated cost per year if the cost of the item is Rs.20.00 per unit. 6Marks
6. a) What is ABC analysis? elaborate the basic steps in implementing it? 6Marks
b) Perform ABC analysis on the subsequent sample of items in an inventory6Marks
