1. A critical survey of optimization methods in industrial forest plantations management
ABSTRACT: The application of optimization methods to forest management has given rise to a successful line of investigation in recent decades. However, there have been few publications associated with the application of these techniques to the management of industrial forest plantations (those with short or medium rotations, always less than 50 years), which

2. SIMULATION OPTIMIZATION FOR ANALYSIS OF SUSTAINABLE LOGISTICS SYSTEMS
ABSTRACT This work analyzed different logistics structures under a sustainable perspective. It wasdeveloped a discrete event simulation model associated with optimization algorithm to evaluate the best combinations of the model. Besides, the comparison between the simulation optimization and a multicriteria method was performed. The simulation software Urura

3. Parametric Modal Study and Optimization of the Floor Pan of a B-Segment Automotive Using a Hybrid Method of Taguchi and a Newly Developed MCDM Model
Abstract The floor pan is an important component that connects the front and rear segments of the automotive underbody structure. Global stiffness and NVH characteristics of BIW are highly dependent to shape, thickness and mass of the body panels and could be evaluated by modal characteristics of these panels. The feeling of solidness and comfort of passenge

4. METAHEURISTICS EVALUATION: A PROPOSAL FOR A MULTICRITERIA METHODOLOGY
ABSTRACT In this work we propose a multicriteria evaluation scheme for heuristic algorithms based on the classic Condorcet ranking technique. Weights are associated to the ranking of an algorithm among a set being object of comparison. We used five criteria and a function on the set of natural numbers to create a ranking. The discussed comparison involves th

5. A SURVEY ON MULTIOBJECTIVE DESCENT METHODS
We present a rigorous and comprehensive survey on extensions to the multicriteria setting of three well-known scalar optimization algorithms. Multiobjective versions of the steepest descent, the projected gradient and the Newton methods are analyzed in detail. At each iteration, the search directions of these methods are computed by solving real-valued optim

6. Sacrificio cortoplacista adaptativo 2opt (SCA_2opt): Una heurística inspirada en el pensamiento sistémico
Outlining two novice heuristics for the symmetric TSP, inspired systemic thinking: Sacrifice short-term adaptive 2-opt (SCA2opt) and SCA_2opt_r. These arise from the systemic analysis of the rule of decision, nearest neighbour, identifying the archetype "Counterproductive solutions". SCA relies on that agent traveler, renounces at any given time immediately

7. A multi-criteria decision model for selecting project portfolio with consideration being given to a new concept for synergies
Project Portfolio Selection (PPS) is a kind of problem found in a variety of practical situations, such as research and development planning. Several different approaches have been proposed to deal with Project Portfolio Selection (PPS). However, the consideration on benefits synergies between projects is little addressed in the literature. The main focus of

8. Pareto optimization of an industrial ecosystem: sustainability maximization
This work investigates a procedure to design an Industrial Ecosystem for sequestrating CO2 and consuming glycerol in a Chemical Complex with 15 integrated processes. The Complex is responsible for the production of methanol, ethylene oxide, ammonia, urea, dimethyl carbonate, ethylene glycol, glycerol carbonate, β-carotene, 1,2-propanediol and olefins, and i

9. Multiobjective optimization techniques applied to engineering problems
Optimization problems often involve situations in which the user's goal is to minimize and/or maximize not a single objective function, but several, usually conflicting, functions simultaneously. Such situations are formulated as multiobjective optimization problems, also known as multicriteria, multiperformance or vector optimizations. Because multiobjectiv

10. Problema de reagrupamento capacitado / Redistricting capacitated problem
The aim of this dissertation is to develop an eficient methodology to solve the multicriteria redistricting capacitated problem (PACM), in which objects with associated weights are given, which must be partitioned into groups with limited capacity. In this work, the PACM is inserted in to a reassignment problem of urban clusters of clients, in which the read

11. MULTICRITERIA OPTIMISATION OF HYDROTHERMAL SYSTEMS OPERATION USING GENETIC ALGORITHMS / OTIMIZAÇÃO MULTICRITÉRIO DA OPERAÇÃO DE SISTEMAS HIDROTÉRMICOS UTILIZANDO ALGORITMOS GENÉTICOS
In Brazil, the planning of the energy operation of the National Interconnected Power System is currently done through a chain of mathematical models designed to optimise the planning according to criterion of minimisation of the expected value of the total operation`s cost. However, since the 2001-2002 energy supply crisis, there was an intensification in th

12. REFEREE ASSIGNMENT IN SPORT TOURNAMENTS: MONO AND MULTI-CRITERIUM ALGORITHMS AND APPLICATIONS / ATRIBUIÇÃO DE ÁRBITROS EM COMPETIÇÕES ESPORTIVAS: ALGORITMOS E APLICAÇÕES MONO MULTI-CRITÉRIO
Optimization in sports is a field of increasing interest. Combinatorial optimization techniques have been applied e.g. to game scheduling and playoff elimination. A problem that arises in competition management is the assignment of referees to games already scheduled. There are a number of rules and objectives that should be taken into account when referees
