“…While geographical logic can be used to accommodate these linkages, more often the functional response models require a direct quantitative relationship to management activities and changes in forests. As was noted in [10], continued efforts in these researchable areas are necessary as the values and needs of society change.…”

“…For example, Rönnqvist [9] provided a valuable overview of the use of optimisation processes in forestry, from strategic and tactical planning of management practices to transportation systems, production planning and other operational concerns. An overview of the general use of optimisation in forestry and agriculture [10] illustrated some of the challenges facing the implementation and use of techniques for systems susceptible to economic and environmental risks and uncertainties. Methods for addressing multi-criteria decision-making processes and group decision making efforts have also been reviewed [11].…”

The field of forestry has employed various computer-assisted optimisation approaches since the early 1960s to address the efficient allocation of resources towards various forest management objectives. These approaches continue to evolve, and in the last 5 years, the research has expanded to demonstrate how complex, non-linear relationships can be recognised and incorporated into planning processes at the tree, stand, forest and landscape levels. In addition to an overview of the use of optimisation in forestry, we provide an examination of work published in the last 5 years from 30 international journals, worldwide, which consistently publish forestry and natural resource management research papers. Through this review, we found that landscape-level optimisation is a relatively new and expanding area of research, most often performed by one large public landowner in regions where the resulting plan of action has an effect on all landowners and resources. We also note that at the forest level, exact methods for optimising systems mainly continue to be used, and at the stand level, optimisation seems to now involve exploration of a variety of analytical methods. A large portion of the recent research in the optimisation of forest management have involved European forests, which is a function of large public ownership of land and the tradition and requirements for management planning, and roughly half of the effort has arisen from researchers located in Nordic countries (Denmark, Finland, Norway and Sweden).

“…Authors such as Arce (1997), Contreras and Chung (2007), Flisberg et al (2007), Seixas (1986), Soares et al (2003) and Weintraub and Romero (2006) developed studies in which they present methods for applied use of geotechnology and operations research tools in forestry planning, obtaining good optimization results in several activities, including log hauling, determination of optimal routes and optimal mill setup sites, distance minimization and transportation cost reduction.…”

ABSTRACT:In view of the need to improve the planning of timber harvest and transportation, with both activities being the most infl uential in determining the fi nal cost of timber delivered to the mill yard, this work aims to develop a new methodological proposal using operations research and geotechnology tools in order to determine optimal locations for log stacking and also the amount of timber to be allocated to each selected stack. Analysis was performed using two software applications, geographic information system (GIS) and operations research (OR). GIS spatial analyses were based on layers of the study site, which is a property owned by Votorantim Celulose e Papel, located in the municipality of São José dos Campos, in order to obtain three variables: degree of diffi culty in operating forestry equipment, degree of diffi culty in log stacking, and distance between log stacks and existing roadways. To obtain these variables, layers containing information on terrain inclination and existing roadways were combined in another analysis named weighted overlay. Results were then fi ltered and inserted into an operations research environment for maximization of the timber volume in each selected stack. With results obtained from the geographic information system, 80 potential sites were selected for log stacking. By using operations research, 59 of these sites were ruled out, a 73% reduction in the number of potential sites, with only 21 sites remaining as potentially optimal for log storage. For each of these 21 sites, an optimal amount of timber was determined to be allocated to each one of them.Key words: Geographic information system, linear programming, log stacking.

“…Also, MCA adds value with regards to other decision support methods because of its ability to make people reveal their preferences and reach compromises, facilitating the achievement of more acceptable outcomes. Multi-criteria methods have a long tradition of use in solving problems related to agriculture and forestry (Romero and Rehman, 1989;Hayashi, 2000;Weintraub and Romero, 2006) and have been used for the construction of composite sustainability indicators; see Díaz-Balteiro and Romero (2004) for an application based on goal-programming.…”

Sustainability of local farming systems and technologies is a very important issue that faces notorious measurement difficulties. Multi-criteria methods may help researchers to solve empirical problems in the construction of composite sustainability indicators and in ranking agricultural technologies according to their sustainability. This paper shows how a multi-criteria decision-making technique, the Analytic Network Process (ANP), can be fruitfully employed to this end. Contrary to simpler and hierarchical goal-criteria-alternative approaches, in ANP all the elements in the network can be related in any possible way, which means that a network can incorporate feedback and interdependent relationships within and between clusters. We illustrate the use of ANP by ranking three rice cultivation technologies -that we call unrestricted traditional, agro-environmental and ecological-in the rice fields of the Albufera Natural Park in Valencia (Spain), using economic, environmental and socio-cultural sustainability criteria. Rice is a multifunctional crop in this area, as flooded rice fields act as semi-natural wetlands, with important ecological consequences, mainly connected with the protection of biodiversity. We show that the ANP methodology is perfectly suited to tackling the complex interrelations involved in sustainability evaluation in this case. We find the ecological cultivation system to be the most sustainable technology. The agro-environmental system ranks second, while the unrestricted system is ranked third. Our results also show that if only the economic dimension of sustainability were considered, the order would be reversed, with traditional unrestricted and ecological technologies exchanging places and the agro-environmental system remaining in second place.Additional key words: biodiversity protection, ecosystems, multi-criteria decision methods, ranking of technologies. Resumen Análisis comparativo de la sostenibilidad de tecnologías de cultivo del arroz mediante el método ANP (analytic network process)La sostenibilidad de los sistemas y tecnologías agrícolas locales es un tema que encara notables dificultades de medición. Los métodos multicriterio pueden ayudar a los investigadores en la construcción de indicadores agregados de sostenibilidad y en la ordenación de las tecnologías agrícolas de acuerdo con su sostenibilidad. Este trabajo muestra como una técnica de decisión multicriterio, el Analytic Network Process (ANP), puede ser empleada al respecto. Contrariamente a otros enfoques, en el ANP todos los elementos de la red pueden ponerse libremente en relación, lo que permite incorporar relaciones de interdependencia y realimentación. Su uso se ilustra ordenando tres tecnologías de cultivo del arroz -tradicional, agroambiental y ecológica-, en los arrozales del Parque Natural de la Albufera (Valencia), con criterios de sostenibilidad económicos, ambientales y socioculturales, que recogen el carácter multifuncional del cultivo del arroz en esta zona. Los resultados muestran que la metodol...
