Chapter 4, Problem 16RP

a.

Explanation of Solution

Consider the following variables:

x₁ = items of type 1

x₂ = items of type 2

Weight of item is a₁ lb and item 2 weighs a₂ lb.

Therefore, the constraints is a₁x₁+a₂x₂ ≤ b

Each type 1 item carries a benefit of c₁ units, each type 2 item carries a benefit of c₂ units...

b.

Explanation of Solution

from the result of part (a), it can be observed that the constraint in linear programming problem is less than or equal to type.

So, add the slack variable s₁ to the constraint.

Thus, the standard form of the linear programming problem is,

Max z= c₁x₁+c₂x₂

Subject to constraints,

a₁x₁+a₂x₂+s₁ = b

The initial simplex table is shown below:

z x₁ x₂ s₁ rhs Basic variable
1 -c₁ -c₂ 0 0 z = 0
0 a₁ a₂ 1 b s₁ = b

Now, there are two negative entries in the row0, suppose the most negative entry is in column 2.

Therefore, choose entering variable to be x₂.

The leaving variable is calculated with the use of the following formula,

Leaving variable = {(rhs/x₁), x₁ ≥ 0}

Consider the below table:

z x₁ x₂ s₁ rhs Basic variable
1 -c₁ -c₂ 0 0 -
0 a₁ a₂ 1 b (b/a₂)→

From the above table, the pivot table is intersection of both entering and leaving variables...

The assignment here is to write an app using a database named CIT321 with a collection named students; we will provide a CSV file of the data. You need to use Vue.js to display 2 pages. You should know that this assignment is similar, all too similar in fact, to the cars4sale2 example in the lecture notes for Vue.js 2. You should study that program first. If you figure out cars4sale2, then program 6 will be extremely straightforward. It is not my intent do drop a ton of new material here in the last few days of class.
