Modern economic under the circumstances enterprise and factories main purpose – limited

resources under the circumstances maximum to income is to achieve . release process effective

organization to grow and profit optimization today's of the day current from issues is one .

Especially , one how many product working removable in factories resources right​

distribution , production release size designation and the most high economic benefit to take for

clear to the calculations rely on important importance profession will reach .

Such issues in solution mathematician modeling methods , in particular , linear programming and

his/her effective solution method was​ simplex method wide is used . Simplex method through

at the factory working release possible was​

products number of them expenses and causing

benefit in consideration taken and optimally worked release plan to compose possible will be .

This in the article simplex method based on product working release plan to compose and

maximum benefit to take opportunities study​

in sight Research​ ​

during working release

resources ( raw materials , labor) power , time and hk ) restrictions under how from products

how much working release need is determined .

Literature analysis

The firm's product working in the release maximum benefit to take plan according to literature

analysis working release processes optimization , resources effective distribution and profit

maximum to the level to deliver according to various methods to determine help gives . L.

Simplex ( method ) in 2 steps is divided .

Stage 1 - Delimiter equations and goal functions canonical to look to bring

Stage 2 - Stage 1 as a result using simplex algorithm​ ​

Then 13 points​ all sizes non-negative unless​ until repeated .

4) W is defined , if W=0 , then it is clear that all artificial variables 0 g a equals . Then equations

(2) from the system last equation and all artificial variables​ lost (2) system again is written .

Harvest made system canonical to look has If W<0 , the solution is no .

Stage 2 obtained in Stage 1 system 's algorithm using from optimization consists of .

Conclusion:

So it can be seen that we should have a production volume of 2 kg of cookies, 30

kg of pasta, 0 kg of lagmanish, and 6 kg of bread. Then we can get maximum profit from the

production of the product.
Answer: the maximum profit is 244.
