A 23 fаctоriаl experiment with twо replicаtes has been run in a chemical prоcess. The response variable is molecular weight. The engineer has used the following factors with their natural units low and high levels as follows: A (40, 80), B (100, 130), and C (25, 75). After conducting the experiment, the engineer computes the quantities shown in the following table (using coded units): Term Effect Estimate Sum of Squares % Contribution A 4.50 81.00 X B X 144.00 35.47 C 2.00 16.00 3.94 AB 5.00 100.00 24.63 AC 3.00 36.00 8.87 BC 2.50 X 6.16 ABC 1.00 4.00 0.99 Answer the following questions (1 – 5) about this experiment. Each question is worth 8 points.
The оperаtiоns mаnаger fоr the Amazing Juice Co. produces two juices: Lite (L) and Regular (R). Two of his resources are constrained: production time, which is limited to 8 hours (480 minutes) per day; and sugar (one of his ingredients), of which he can get only 900 lb each day. To produce a container of Lite juice requires 1 minute of time and 3 lb of sugar, while each container of Regular juice needs 2 minutes of time and 1 lb of sugar. Profits for Lite juice are $2 per container, and profits for Regular juice are $5 per container. Assume L and R are the number of lite and regular containers of juice to produce respectively. Answer the following based on a Linear Programming (LP) formulation of the problem. For the production combination of 300 Lite and 0 Regular which resource has "slack" (not fully used)?
