Answer 1

Answer:

Formulation of L.P model:

Key decision is to determine how the paper rolls be cut to the required widths so that trim losses(wastage) are minimum.

Let x

j

(j=1,2,...6) represent the number of times each cutting alternative is to be used.These alternatives result/do not result in certain trim loss.

Objective is to minimize the trim losses.

i.e., minimize Z=x

Constraints are on the market demand for each type of roll width:

For roll width of 3cm, 4x

and For roll width of 10cm, x

≥500

Since the variables represent the number of times each alternative is to be used,they cannot have negative values.
