Modelo de evaluación de la gestión logística en empresas

Diversos estudios apuntan a que el desarrollo de cualquier área de gestión empresarial requiere tanto de la existencia de sistemas de gestión para los procesos implicados, como de modelos de evaluación y diagnóstico basados en su correspondiente sistema de gestión. En el área de la gestión logística, la literatura científica y diversos trabajos técnicos ya recogen la existencia de un sistema de gestión logística (modelo CPLA). Por tanto, este trabajo desarrolla un modelo de evaluación basado en el modelo CPLA de gestión logística, contando además con la experiencia de aplicación en más de 30 empresas de diversos sectores industriales

PLANNING ROUTES AND SHIFTS DRIVING FOR A SMALL BUSINESS OF ROAD PASSENGER TRANSPORT

The presented work is done for a company that currently operates twenty lines of passenger transport in the metropolitan area of Seville. The planning of these was originally carried out manually, building routes and shifts in an Excel spreadsheet. In order to automate the process as much as possible. It was designed and implemented by a scheduling algorithm that would be much simple than other algorithms in the literature and that, in addition, would make it possible to allow mixing vehicles and drivers between the lines. The objective was, firstly, to employ the minimum number of drivers; then, it is trying to use the least possible number of vehicles; finally, the study tries to reduce as much as possible the amount of split shifts. In addition, restrictions on the design of routes and shifts were added. At all times the service frequencies remained above the set limit. To allow the possibility of unexpected demand peaks, was established in the capacity of each route some slack

Quantitative assessment of sustainable city logistics

The aim of this paper is to seek an answer to an specific question: how to make city logistics sustainable? This question in principle has no specific answer. By contrast, it could be answered in many and varied ways. Behind the search for some of these answers lies the development of a roadmap which this work aims to present. The research lines, the theoretical framework and methodology of the roadmap will be explained. Although the current status of the roadmap, its duration and timing still need to be completed, the main facts, as well as the results obtained to date and the expected results are here presented

Distribución de mercancías y desarrollo urbano sostenible

Urban freight deliveries should be analyzed by focusing on the three sustainability axes: economic, social and environmental. Within the scope of sustainable urban development, it is important to develop an urban freight system that is sustainable and efficient, which is extremely complex due to the enormous variety of freight deliveries co-existing in a city and to the multiple stakeholder groups involved in the problem, which often results in the appearance of conflict areas. This paper describes all that complexity and provides details on the main responses that may be given at the urban framework, both from the industry and from the local authority, always taking into account that the regulations imposed to achieve sustainability in urban freight deliveries might not result as expected.El reparto urbano de mercancías debe ser contemplado en relación con los tres ejes de la sostenibilidad: el económico, el social y el medioambiental. Dentro de los parámetros del desarrollo urbano sostenible, es importante conseguir una logística urbana sostenible y eficiente, lo cual es extremadamente complejo debido a la gran variedad de repartos de mercancía existentes en la ciudad y a los numerosos grupos de actores involucrados en el problema, lo cual genera con frecuencia numerosas áreas de conflicto. En este artículo se describe toda esa complejidad y se detallan las principales respuestas que pueden darse en el ámbito urbano, tanto a nivel empresarial como desde la administración local, teniendo en cuenta el riesgo de que en ocasiones el resultado de las medidas impuestas para conseguir un reparto de mercancías más sostenibles no sea el esperado.
