Operations research to develop optimization processes in forest management: Field determination of multivariate models
The most widely used technique in operations research is linear programming, and one of the most widely used algorithms in this field is simplex method. The management of forest ecosystems is an ideal field to implement optimization models, since clear goals must normally be met, and the available resources are usually limited. The aspects involved are complex, several routes of action can be taken, and it is important in order to make the best decision. The simplex method, once objective function and restrictions are established, allows to consider all the possibilities, and make the decision that provides the greatest advantages. Undoubtedly, a wrong decision can cause damage to forest ecosystem and economic losses, so a tool that helps in this work will always be a great ally. Once the problem has been formulated in mathematical terms, software or programming languages specialized are usually required, which can be a problem if access to computer equipment and internet connectivity is not the most appropriate. Mobile devices such as cell phones, tablets, and programmable calculators have become small computers at an affordable price, with increasingly 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 previously required very sophisticated computers. This work reviews the options currently available to run simplex method, both analytically and graphically, on portable devices. This topic is of interest to both professional and student of forestry sector.

La técnica más utilizada de la investigación de operaciones es la programación lineal, y uno de los algoritmos más ampliamente usados en este ámbito es el método simplex. El manejo de ecosistemas forestales es un campo idóneo para la implementación de modelos de optimización, pues normalmente se deben cumplir metas claras y los recursos disponibles por lo regular son limitados. Los aspectos involucrados son complejos, se pueden tener varias rutas de acción, y es importante tomar siempre la mejor decisión. El método simplex, una vez que se tiene la función objetivo y se establecen las restricciones, permite considerar todas las posibilidades, y tomar la decisión que brinde las mayores ventajas. Sin duda, una decisión mal tomada puede ocasionar perjuicios al ecosistema forestal y pérdidas económicas, por lo que una herramienta que ayude en esta labor siempre será una gran aliada. Una vez que se ha formulado el problema en términos matemáticos, normalmente se requiere software o lenguajes de programación especializados, lo que puede ser un problema si está en campo y el acceso a un equipo de cómputo y de conectividad a internet no es el más adecuado. Los dispositivos móviles como teléfonos celulares, tabletas y calculadoras programables se han convertido en pequeñas computadoras a un precio accesible, con procesadores cada vez más potentes y una buena cantidad de memoria. Esto aunado a la disponibilidad de aplicaciones del método simplex, o incluso la capacidad de programarlo directamente en estos dispositivos, hace posible tener en la palma de la mano herramientas que antes requerían computadoras muy sofisticadas. En este trabajo se revisan las opciones actualmente disponibles para correr el método simplex, tanto de manera analítica como gráfica, en dispositivos portátiles. Este tema es de interés tanto para el profesionista como para el estudiante del sector forestal.
