Investigación de operaciones para desarrollar procesos de optimización en manejo forestal: determinación en campo de modelos multivariados

The most widely used technique in operations research is linear programming, and one of the most widely used algorithms in thisfield is simplex method. The management of forest ecosystems is an ideal field to implement optimization models, since clear goalsmust normally be met, and the available resources are usually limited. The aspects involved are complex, several routes of actioncan be taken, and it is important in order to make the best decision. The simplex method, once objective function and restrictions areestablished, allows to consider all the possibilities, and make the decision that provides the greatest advantages. Undoubtedly, awrong decision can cause damage to forest ecosystem and economic losses, so a tool that helps in this work will always be a greatally. Once the problem has been formulated in mathematical terms, software or programming languages specialized are usuallyrequired, which can be a problem if access to computer equipment and internet connectivity is not the most appropriate. Mobiledevices such as cell phones, tablets, and programmable calculators have become small computers at an affordable price, withincreasingly powerful processors and a good amount of memory. This, coupled with availability of applications of simplex method,or even the ability to program it directly on these devices, makes it possible to have in the palm of hand tools that previouslyrequired very sophisticated computers. This work reviews the options currently available to run simplex method, both analyticallyand graphically, on portable devices. This topic is of interest to both professional and student of forestry sector.
