New Operations Science Study Results Reported from University of Bucharest (A portfolio theory approach to crop planning under environmental constraints)

By a News Reporter-Staff News Editor at Science Letter -- A new study on Science is now available. According to news reporting from Bucharest, Romania, by NewsRx journalists, research stated, "This paper presents a multiobjective model for crop planning in agriculture. The approach is based on portfolio theory."

The news correspondents obtained a quote from the research from the University of Bucharest, "The model takes into account weather risks, market risks and environmental risks. Input data include historical land productivity data for various crops, soil types and yield response to fertilizer/pesticide application. Several environmental levels for the application of fertilizers/pesticides, and the monetary penalties for overcoming these levels, are also considered. Starting from the multiobjective model we formulate several single objective optimization problems: the minimum environmental risk problem, the maximum expected return problem and the minimum financial risk problem. We prove that the minimum environmental risk problem is equivalent to a mixed integer problem with a linear objective function."

According to the news reporters, the research concluded: "Two numerical results for the minimum environmental risk problem are presented."
