The selection of a portfolio of investment through a multi-objective mathematical model indicates that it possible have several available portfolios. In our model, the selection of one of them is performed with the same principle used by the Capital Assets Pricing Model, a single point touches the border of optimal portfolios. The model is tested with… (More)

The algorithm of multiplication of matrices of Dekel, Nassimi and Sahani or Hypercube is analysed, modified and implemented on multicore processor cluster, where the number of processors used is less than that required by the algorithm n3. 23, 43 and 83 processing units are used to multiply matrices of the order of 10x10, 102x102 and 103X103. The results of… (More)

Optimization approaches have traditionally been viewed as tools for solving manufacturing problems, the optimization approach is not suitable for many problems arising in modern manufacturing systems due to their complexity and involvement of qualitative factors. In this paper we use a tool of software engineering applied to manufacturing problems. We use… (More)

This paper presents a parallel hybrid evolutionary algorithm executed in a grid environment. The algorithm executes local searches using simulated annealing within a Genetic Algorithm to solve the job shop scheduling problem. Experimental results of the algorithm obtained in the “Tarantula MiniGrid” are shown. Tarantula was implemented by linking two… (More)

This paper presents an algorithm that applies a new mechanism in order to generate scheduling which allows for evaluation of the quality of solutions that are obtained in the Job Shop Scheduling Problem (JSSP). In this research, the quality of the solution is evaluated by using the makespan as an objective function. It is demonstrated experimentally that… (More)
