This quantitative study offers the partial results of a research project conducted in a population of medium-sized businesses in Lara State, Venezuela. The objective was to determine whether there is a relationship between the variables of organizational design: centralized decision making and intrinsic rewards. The theoretical framework developed provides a general hypothesis which was tested in a field study. Methodologically, the measurement scales of the studied variables were assessed for its reliability, and content validity and construct. Data processing consisted of statistical correlation analysis and simple regression. Results show that there is a significant negative relationship between a centralized system and the implementation of intrinsic rewards in the organization. / El presente trabajo de naturaleza cuantitativa ofrece los resultados parciales de un proyecto de investigación llevado a cabo en una población de medianas empresas del estado Lara, Venezuela1, y cuyo propósito fue determinar si existe una relación entre las variables de diseño organizativo: centralización de la toma de decisiones y los incentivos intrínsecos.Del desarrollo del marco teórico, se desprende una hipótesis general que fue contrastada a través de un estudio de campo. Metodológicamente, las escalas de medición utilizadas para operacionalizar las variables objeto de este trabajofueron sometidas tanto a la evaluación de su fiabilidad como de su validez de contenido y de constructo. El tratamiento de los datos se realizó mediante la aplicación de análisis estadísticos de correlación y regresión simple. Los resultados muestran que existe una relación negativa y significativa entre la centralización de la toma de decisiones y la implementación en la organización de incentivos intrínsecos. / Este estudo quantitativo apresenta os resultados parciais de uma pesquisa realizada em uma população de médias empresas no estado de Lara, Venezuela.

O referencial teórico formula uma hipótese geral que foi testada numa pesquisa de campo. Metodologicamente, foram avaliadas a confiabilidade e a validade de conteúdo e construção das variáveis estudadas. O processamento de dados foi realizado utilizando a análise de correlação e regressão simples. Os resultados mostram que existe uma relação negativa significativa entre a tomada de decisão centralizada e as recompensas intrínsecas na organização.

This thesis deals with the optimization of the structural design of large technology compounds. The main emphasis is placed on the participation of available optimization instruments in the design of supporting structures of these constructions. The introductory part is primarily focused on the optimization itself. In this part are further specified also used optimization methods, computational finite element method, implemented code checks and calculation of cost of construction. The main part is dedicated to application of optimization procedure for the design of steel supporting structure of the auxiliary technological object of thermal power plant. The objective criterium shall then constitute the total cost of construction works along with operating costs. For the solution is used Scia Engineer software together with optimization module Scia Engineer Optimization Toolbox. The whole analysis is presented comprehensively from the description of computational model to results evaluation. The attention is paid to the optimization task settings, technical solution of optimization, optimization methods deployment and during the calculation process (especially to the development of objective function values and desing constraints during the optimization solution).
