Alternative producer-consumer relationships: the AgroGeoTrace project and the speciality products virtual roads
No full textThe AgroGeoTrace (AGT) project makes use of Geographical Information Systems and multichannel information technologies to facilitate the access of final consumers to local food speciality products. The project builds a prototype of an informative system designed, first, to help consumers to understand the agronomic and technological characteristics that make the targeted products special ones, and, second, to precisely and easily locate the sites (farms and oil mills) where they can buy them. The information made available through the project is intended to the symbolic relocalization of the regional products, hence to promote them and to create added value. The final outcomes of the project are the virtual maps of on-farm shops made available on Digital television (channel In+), PDAs and mobile phones.food speciality products, short agro-food chains, Geographical Information Systems, Agribusiness,

Bayes Availability Estimation of the “k-out-of-n” Partially Redundant System by Lognormal Prior Distributions
No full textThe “k-out-of-n” partially redundant reliability
architecture is a flexible and economic configuration for many
engineering systems, such as motor drive applications, in
various industrial, aerospace and naval systems. The present
study is aimed to develop a Bayesian statistical inference
approach for the steady state availability estimation of such
systems. The proposed approach is based upon Lognormal prior
distributions for both hazard and repair rates. The Lognormal
model appears indeed not only very flexible, but also
particularly tailored for electronic devices, as motivated in the
paper. A set of numerical applications with typical parameter
values is illustrated in the study, showing - by means of a large
sets of Monte Carlo simulations - that the proposed Bayesian
statistical inference approach is very efficient, accurate and
robust for the above availability estimation, particularly in the
case of data scarcity, which is a key feature of such high
reliability devices in view of parameter estimation. Beyond point
estimation, the study also develops an efficient method to obtain
the interval estimation of system availability by means of a
suitable Beta distribution approximation. Also a robustness
analysis of the above Lognormal model has been successfully
developed
