Why did we choose this case?
Healthy nutrition is one of the most significant issues in today’s world. Obesity has becoming more and
more dangerous problem all around the world and especially in America. The governments and the non-
governmental organiations constantly create and implement strategies for struggling this problem. !os
of the e"perts believe that main reason of the nutrition problems comes from the agricultural cultivation.
We thin# the conflict between the purpose of farmers or food producers which is always profit
ma"imiation and re$uirements of being healthy is a crucial point in this case. Therefore% we wanted to
ma#e a linear programming for agricultural planning in order to show how they ma#e the production
process.
&efinition of the 'roblem
We have ()) acres of land to produce orange% corn% peanut and sunflower. One of the most important
priorities of our production strategy is to use our land with full efficiency. We assume that other details
are. The specified details are below*
We have + different plants for our + different plant to produce. ,aturally% each plant has different returns
and different re$uirements. t is not obliged to plant each product at the same amount.
The returns for each product is at the table below* all of the data are measured in dollars/*

Also% there are of course operational re$uirement that oblige us to have some additional constraints*
• Acres of orange% peanut and sunflower planted cannot e"ceed half of the entire field% however
planted corn can e"ceed.
• 7overnment regulation as to the $uotas re$uires that acres of planted corn and sunflower
combined should at least be 82)
• !a"imum fertilier can be used on ()) acres cannot e"ceed +)))
• Total budget is 62))
• Our ob9ective is to ma"imie our profit
Ac$uiring nput &ata
&ata regarding the $uotas come from !inistry of Agriculture and 5orests
&ata regarding ma"imum proportion of acres come from production planning and operations

5inancial data such as cost and profit comes from a management consultancy firm to whom we had outsourced the tas#
The #nowledge of acres occupied comes from surface survey results
nternational agreement clauses come from the :nited ,ations
