Industria 4.0 Senza Slogan
Full text linkSenza grossa fatica l’Industria 4.0 potrebbe essere letta come un’azione di marketing (riuscitissima) ad opera di un gruppo di vari attori, tutti con sede in Germania. D’altronde l’idea di una fabbrica totalmente digitalizzata non ha potuto che trovare favorevoli i grandi e piccoli provider di software e di sistemi di nuova generazione (cloud, 4G, ecc..) che hanno iniziato a fare da cassa di risonanza al concetto di Industria 4.0.
L’argomento purtroppo si presta a varie interpretazioni e a varie strumentalizzazioni, anche in attesa di fondi europei stanziati ad hoc. Ogni punto di vista adottabile per descrivere la filosofia 4.0 porta inevitabilmente una distorsione, data dalla specifica prospettiva scelta. Può un concetto nato nel mondo delle grandi imprese tedesche essere preso senza adattamenti alla realtà italiana? Certamente no, occorre uno sforzo di reinterpretazione e adattamento. Ma allora cosa può significare, in concreto, Industria 4.0 in Toscana, ed in particolare nella pratica e nella vita quotidiana delle PMI
Training assessment: a source of key performance indexes for University
No full textIn most universities in Italy the students, to complete their academic curriculum, have
to perform a training period. This is an effect of the D.M. 509/99, aiming to a deep
reorganization of the whole structure of the higher education. In the case of
engineering university courses, it is often developed for a company. Although it is a
very useful experience for the student, the introduction of training in the student’s
curriculum does not involve a real change in the relationships between University and
industrial world. In this paper the status of the trainings in two engineering university
courses at the University of Pisa is shown. This report is used to highlight new
possibilities to be investigated to transform the training in a resource for the
universities. A proposal for the development of some KPIs (Key Performance Indexes)
useful to improve and make more effective the evaluation of University rating is also
described
A modular contactless feeder for microparts
No full textThis paper describes the development of a feeder for mini and micro parts. A complete study of a feeding
method based on electrostatic fields is presented. Through a theoretical analysis and experimental results the
optimized configuration of the feeder is proposed, shown and discussed. The performances of possible
alternative configurations are quantitatively compared according to the variation of the process parameters. In
addition the paper presents a flexible and reconfigurable system based on standard modules easy to be linked
by rapid set up operations
Designers' promises or users' expectations?
No full textSeveral frameworks describe the design process, such as the FBS model and its extensions. Some of them present a designer-centric view, while the most recent ones are more based on the user's point of view. This paper investigates and seeks to explain the different perspectives between designer and user after the first interactions with the product. In particular, the paper models how the designer's promises of functionalities match (or mismatch) the user's expectations. Thus twenty-four examples, including misuses, unperceived functions, hidden functions, failures etc., are mapped in a table. The paper provides also a formal model based on Function-Behavior-Structure approach to describe the possible cases of misunderstanding between the user and the designer. Such a model formally links the designed product, as it is conceived by the designer, and the perceived product, as it is understood and interpreted by the user. Finally a series of redesigned actions are proposed to try to overcome some of the cases of misunderstanding between the user's and the designer's perspectives
