The best Weibull distribution methods for the assessment of wind energy potential at different altitudes in desired locations are statistically diagnosed in this study. Seven different methods, namely graphical method (GM), method of moments (MOM), standard deviation method (STDM), maximum...

This paper presents a formal analysis of the consolidation effect in a wider perspective. While demonstrating that the stock saving structure depends on the interaction between the coefficient of variation of demand and the ratio between inventory ordering and holding costs, this research...

This paper presents a framework for identifying the most adequate distribution structure between manufacturing and retailers, considering different characteristics of product, operation, and demand. Based on the random generation of different scenarios, it is indicated the adequacy of direct,...

The article investigates the Brazilian third-party logistics (3PL) sector which, increasingly competitive, offers clients a wide variety of services/IT technologies in the quest to bolster efficiency. The main research objective is to determine which variables significantly impact 3PLs scale...

This paper presents a framework for deciding whether and how inventories should be pooled, using the consolidation effect as a cornerstone tool to measure inventory costs, service levels, and total costs. Based on the random generation of different scenarios, it is indicated the adequacy of...

Efficiency in Brazilian airports is measured using a two-stage process. In the first stage, physical infrastructure efficiency, assets, such as terminal area, aircraft parking spaces, and runways are related to the number of landings and take-offs per year. The second focuses on flight...

This paper reports on the use of different approaches for measuring efficiency in 65 major Brazilian airports. Several programming based estimates were generated to allow testing for significant differences in returns-to-scale and input-decreasing/output-increasing potentials. The findings...

Port efficiency has been widely studied using standard DEA (Data Envelopment Analysis) models and its variations. As a matter of fact, these models do not account for the internal structure relative to measures characterizing port operations performance. In this paper, efficiency in Brazilian...

This paper reports on the use of different approaches for assessing efficiency of a sample of major Brazilian for-profit hospitals. Starting out with the bootstrapping technique, several DEA estimates were generated, allowing the use of confidence intervals and bias correction in central...
