Resource Availability: 40 hrs of labor per day; 120 lbs of wood
Decision Variables: x1 = number of Hockey Sticks to produce; x2 = number of Chess Sets to produce
Identify the Objective Function: Z = ___40____x1 + __50_____x2
Identify the Constraint Equation for Labor: ___1____x1 + __2_____x2 <= ____40___
Identify the Constraint Equation for Wood: _____4__x1 + ____3___x2 <= 120_______
Identify any other Constraint Equation(s):
Point A: X1 = ___30______ X2 = ______0___ Z = ____1200_____
Point B: X1 = _____24____ X2 = ____8_____ Z = _____1360____
Point C: X1 = ______0___ X2 = ___20______ Z = _____1000____
A.) Optimal point is (Circle one) Point A Point B Point C
B.) Is there any slack associated with labor? Yes No, If yes, how many hours? _________
C.) Is there any slack associated with wood? Yes No, If yes, how many pounds? _________
Objective Function: Z = 40x1 + 50x2
Constraints:
x1 + 2x2 <= 40 [Constraint on Wood]
4x1 + 3x2 <= 120 [Constraint on labor]
x1 >= 0 [number of hockey sticks must be greater than zero]
x2 >= 0 [number of chess sets must be greater than zero]
We need to maximize objective function Z with the above constraints
a) Optimal Point will be the point B producing maximum profit of $1360
b) Number of labor hour used = 24 * 1 + 2 * 8 = 40
Available hours = 40
Hence there is no labor hours left, so the slack is (40-40) which is zero
No slack
c) Number of wood used = 24 * 4 + 3 * 8 = 120
Available hours = 120
Hence there is no wood hours left, so the slack is (120-120) which is zero
No slack

Solve these problems using graphical linear programming and answer the questions that follow. Use simultaneous equations to determine the optimal values of the decision variables. a) Maximize Z = 2x1 + 10x2 b) Maximize Z = 6A + 3B (revenue) For both questions, answer the following: (1) What are the optimal values of the decision variables and Z? (2) Do any constraints have (nonzero) slack? If yes, which one(s) and how much slack does each have? (3) Do any constraints...
Ahmadi, Inc. manufactures laptop and desktop computers. In the upcoming production period, Ahmadi needs to decide how many of each type of computers should be produced to maximize profit. Each computer goes through two production processes. Process I,involves assembling the circuit boards and process IIis the installation of the circuit boards into the casing. Each laptop requires 24 minutes of process I time and 16 minutes of process II time. Each desktop requires 8 minutes of process I time and 32 minutes of process...
Use the following information to answer question 17 through 19: 17. Doherty & Puthoff, Inc. produces quality BGSU hats for fashion-conscious students. During the year, its highest and lowest production levels occurred in April and October, respectively. In April, it produced 6,000 units at a total cost of $120,000. In October, it produced 2,000 units at a total cost of $80,000. Using the high/low method of estimating costs, the average variable cost of producing a hat would be: a. $10.00...
Risk management in Information Security today Everyday information security professionals are bombarded with marketing messages around risk and threat management, fostering an environment in which objectives seem clear: manage risk, manage threat, stop attacks, identify attackers. These objectives aren't wrong, but they are fundamentally misleading.In this session we'll examine the state of the information security industry in order to understand how the current climate fails to address the true needs of the business. We'll use those lessons as a foundation...
