A Norm-Governed Holonic Multi-agent System Metamodel

2013

Modeling and designing systems that require a high level of coordination, control and automation is a very difficult task. The problem is the lack of design processes able to cover all the features these systems present. This paper presents an extension of the ASPECS metamodel for supporting organizational and normative principles and it allows to define models not only from an holonic agent viewpoint but also from a normative organization perspective. Moreover, our work emphasizes and makes it explicit the norms that regulate the structural, behavioral and finally adaptive aspect of an organizational system. The extended metamodel was experimented creating a Virtual Enterprise model for th…

Partially hyperbolic diffeomorphisms on Heisenberg nilmanifolds and holonomy maps

2014

Abstract In this note we show that all partially hyperbolic automorphisms on a 3-dimensional non-Abelian nilmanifold can be C 1 -approximated by structurally stable C ∞ -diffeomorphisms, whose chain recurrent set consists of one attractor and one repeller. In particular, all these partially hyperbolic automorphisms are not robustly transitive. As a corollary, the holonomy maps of the stable and unstable foliations of the approximating diffeomorphisms are twisted quasiperiodically forced circle homeomorphisms, which are transitive but non-minimal and satisfy certain fiberwise regularity properties.

Approccio olonico e sistema logistico-produttivo aziendale per i mercati del XXI secolo

2008

L’impresa industriale deve oggi far fronte a problematiche di rapidità ed efficacia di gestione dei processi, in presenza di frequenti disturbi e cambiamenti negli ordini di produzione. La gestione della Supply Chain (SCM) deve tenere conto di queste tendenze e trovare un paradigma organizzativo-gestionale in grado di fornire all’azienda la richiesta agilità e capacità di sincronizzazione del sistema logistico-produttivo con le nuove caratteristiche dei mercati. Ne i sistemi gerarchici ne quelli eterarchici sono in grado di soddisfare questi requisiti, mancando della necessaria agilità i primi e della capacità di garantire la prevedibilità necessaria alla sincronizzazione i secondi. L'idea …

Tractional Motion Machines extend GPAC-generable functions

2012

In late 17th century there appeared the Tractional Motion instruments, mechanical devices which plot the curves solving differential equations by the management of the tangent. In early 20th century Vannevar Bush’s Differential Analyzer got the same aim: in this paper we’ll compare the Differential Analyzer mathematical model (the Shannon’s General Purpose Analog Computer, or GPAC) with the Tractional Motion Machine potentials. Even if we will not arrive in defining the class of the functions generated by Tractional Motion Machines, we’ll see how this class will strictly extend the GPAC-generable functions.
