In this work, we propose an integer linear programming model for production scheduling of a group of finished products with independent demand. The model for the master production scheduling (MPS) is designed by considering production and inventory costs, as well as the productive process...

It is known that, when in the linear regression model there is a high degree of multicollinearity, the results obtained by using the Ordinary Least Squares (OLS) method are unstable. As a solution to this situation, in this paper we present the raised method, the ridge method and the orthogonal...

The last three decades have been a story of lost opportunities for Spanish industry to transform and improve their international competitiveness. However, there are some paradigmatic examples that violate this rule. This is the case of two Spanish companies: Hidden Champions and Brand Champions....

The aim of this study was to determine the effects of the cooperative ``jigsaw'' method on generic competence-based training by university students. This specifically sought to understand how systemic, instrumental and interpersonal competences are more easily acquired by adopting ``jigsaw'' in...

The objective of this paper is to explain academic performance with the aid of an innovative technique: Fuzzy-set Qualitative Comparative Analysis (fsQCA). To do so, different objective factors, which affect higher education, are analyzed and the academic performance of university students is...

This paper introduces the use of graphs in the analysis of the determinants of tourists' expenditure, providing an alternative approach to the methods usually employed. Graph-based analysis is applied to study the behavior of cruise passengers arriving at the ports of Montevideo and Punta del...

The paper studies the behavior of the household saving rate during the period from 1985 to 2016. We examine the variables considered by the literature to determine the long-term saving rate: Income, wealth, unemployment, credit and indebtedness, public savings, population structure, social...

This paper develops a continuous-time random model of loss index triggers for cat bonds on the basis of the loss amount incurred until their maturity. Assuming that total loss amount due to a catastrophe is defined as the sum of the incurred loss amount plus the incurred-but-not-yet reported...

The export commitment is often a key to explain why some firms export more than other business aspect. This article discusses the determinants of export commitment in Colombian SMEs from the behavioral and attitudinal viewpoint using a neural network model estimated on a sample of 306 exporting...
