"Las claves del éxito de Toyota". LEAN, más que un conjunto de herramientas y técnicas

[ES] Cuando se habla de LEAN, inmediatamente se piensa en Toyota y en su continuo éxito. De ahí que hayan sido muchas las empresas que han intentado seguir su modelo: el TPS (Sistema de Producción Toyota) o el modelo LEAN, basado en él. Sin embargo, pocas lo han conseguido. El libro titulado «Las claves del éxito de Toyota», creemos que da la respuesta a través de catorce principios que comentaremos en este artículo.

Choice of Flexible Production Technologies Under Strategic Delegation

This work analyzes a managerial delegation model in which firms can choose between a flexible production technology which allows them to produce two different products and a dedicated production technology which limits production to only one product. We analyze whether the incentives to adopt the flexible technology are smaller or greater in a managerial delegation model than under strict profit maximization. We obtain that the asymmetric equilibrium in which only one firm adopts the flexible technology can be sustained under strategic delegation but not under strict profit maximization when products are substitutes. We extend the analysis to consider welfare implications.

Cost-Saving production technologies and strategic delegation

This work analyzes a managerial delegation model in which firms that produce a differentiated good can choose between two production technologies: a low marginal cost technology and a high marginal cost technology. For the former to be adopted more investment is needed than for the latter. By giving managers of firms an incentive scheme based on a linear combination of profit and sales revenue, we find that Bertrand competition provides a stronger incentive to adopt the cost-saving technology than the strict profit maximization case. However, the results may be reversed under Cournot competition. We show that if the degree of product substitutability is sufficiently low (high), the incentive to adopt the cost-saving technology is larger under strict profit maximization (strategic delegation).

Breed effect on quality veal production in mountain areas: Emphasis on meat

This study was designed to compare the quality of veal produced from ‘Tudanca x Charolais’ cross (n=6) and Limousin (n=6) breeds when allowed to feed freely on mountain pastures and suckle naturally from birth to 7 months of age. After 80 days of age calves also had access to concentrate (maximum of 3 Kg/day), while mothers did not. At slaughter, Limousin calves were heavier (P<0.01) and provided better carcass yield (P<0.05) and conformation (P<0.001) than Tudanca calves. Tudanca beef provided higher fat content (P<0.05) was less tough (P<0.05), and was scored as more tender and juicy (P<0.1) with higher acceptability than Limousin beef (P<0.1). In general, Tudanca had a better fatty acid profile than Limousin beef, especially in terms of the content of polyunsaturated (P<0.05), long-chain polyunsaturated fatty acids (P<0.05) and their n-6/n-3 ratios (P<0.1), as well as vaccenic acid (P<0.1) and the overall trans-18:1 isomer profile.

Diseño de líneas mixtas en un entorno Lean. Aplicación a un caso mediante Excel

[ES]Este trabajo tiene como objetivo analizar las soluciones existentes para el diseño de las líneas mixtas. Se trata de un tipo de líneas bastante complejas de diseñar y que por lo general han sido poco estudiadas por la sociedad académica, a pesar de las numerosas ventajas que ofrece en comparación a las líneas simples, mucho más investigadas. Para facilitar la comprensión de su diseño, y antes de su estudio, se realiza un análisis de las características de las líneas mixtas. Posteriormente se introduce una metodología desarrollada por Lluis Cuatrecasas (Presidente del Instituto Lean Management de España), que permite salvar la brecha que existe a su juicio entre los estudios sobre los diseños de este tipo de líneas y su aplicación a la empresa. Finalmente, se ilustra dicha metodología mediante un caso práctico y se evalúan sus fortalezas y debilidades.
