1. Hybrid Quaternions of Leonardo
ABSTRACT In this article, we intend to investigate the Leonardo sequence presenting the hybrid Leonardo quaternions. To explore Hybrid Quaternions of Leonardo, the priori, sequence of Leonardo, quaternions and hybrid numbers were presented. Soon after, its recurrence, characteristic equation, its relation with the Fibonacci quaternions, generating function,

2. Rotated ℤn-Lattices via Real Subfields of ℚ(ζ2r)
RESUMO Um método para construir ℤ n-reticulados rotacionados, com n uma potência de 2, via subcorpos totalmente reais do corpo ciclotômico ℚ ( ζ 2 r ), onde r ≥ 4 é um inteiro, é apresentado. Reticulados que exibem diversidade completa em algumas dimensões n não abordadas anteriormente são obtidos.ABSTRACT A method for const

3. Uma Nova Proposta para a Obtenção da Complexidade de Pior Caso do ShellSort
RESUMO A complexidade de pior caso do ShellSort, um algoritmo de ordenação por comparação, depende de uma sequência de passos dada de entrada. Cada passo consiste de um inteiro representando a diferença de índices dos pares de elementos que devem ser comparados durante a ordenação de um vetor de entrada. Tal complexidade é conhecida somente para al

4. ORGANIZING BUSINESS FORUMS WITH INTEGER LINEAR PROGRAMMING
ABSTRACT Business associations often promote forums between entrepreneurs. One strategy for establish contacts among participants is to organize them into small groups assigning them to tables so that participants in the same group can present their companies and projects. After an interval, a new round begins with new groups in order to establish new contac

5. CAPACITATED LOT SIZING AND SCHEDULING WITH ORDER ACCEPTANCE AND DELIVERY TIME WINDOWS: MATHEMATICAL MODEL AND A MIP-BASED HEURISTIC
ABSTRACT This research addresses a lot sizing and scheduling problem inspired by a real-world production environment where the customers make advanced orders and the industry need to decide which orders will be accepted with the aim of maximizing the profit respecting the production capacity constraints. Orders are composed of different types of items which

9. ANALYSIS OF MIXED INTEGER PROGRAMMING FORMULATIONS FOR SINGLE MACHINE SCHEDULING PROBLEMS WITH SEQUENCE DEPENDENT SETUP TIMES AND RELEASE DATES
ABSTRACT The scheduling of jobs over a single machine with sequence dependent setups is a classical problem setting that appears in many practical applications in production planning and logistics. In this work, we analyze six mixed-integer formulation paradigms for this classical context considering release dates and two objective functions: the total weigh

10. NEW THEORETICAL INVESTIGATIONS ON THE GAP OF THE SKIVING STOCK PROBLEM
ABSTRACT The one-dimensional skiving stock problem is a combinatorial optimization problem being of high relevance whenever an efficient and sustainable utilization of given resources is intended. In the classical formulation, a given supply of (small) item lengths has to be used to build as many large objects (specified by some target length) as possible. F

11. Spatial Forest Planning for Optimized Harvest Scheduling
ABSTRACT The aim of this study was to develop a mathematical model for the spatial forest planning of harvest activity scheduling. Thirty-eight (38) blocks were formed from stands aged 13 to 17 years considering a total area limit set to 350 hectares. The model was built in Excel ® spreadsheet and solved by CPLEX® optimization software using the Branch an

12. Computational Model for Microgeneration Simulation, From Solar and Wind Renewable Sources, With Optimal Allocation of Loads, Electric Vehicle and Energy Storage, In a Residential Electrical Micro Network
Abstract The electrical sector is under constant evolution. One of the areas refers to the consumers that come to be generators, implementing distributed generation, interconnected to a smart grid. This article discusses the improvement of an algorithm, already presented in the literature, to make the best temporal allocation of loads, electric vehicle, stor
