Cyber Enterprise Visual Interfaces (CEVI)

Cyber Enterprise functionality and Ptolemy II (Vergil) integration for Virtual Component (VC) based simulation


Cyber EnterpriseActivity Plan

  • Virtual Enterprise (VE) Model, Goals and Instruments

  • User Requirements Analysis

  • Technical Specifications according to the Usability Methodology

  • Virtual Enterprise Architecture

  • Virtual Enterprise Components (Modules)

  • Virtual Enterprise General Management

  • Web – DBs and

  • Advanced Visual Interface (AVI)


Virtual Enterprise

  • The term "virtual" usually stands for something that is seemingly existing despite the lack of some distinguishing attributes. Thus, for example "virtual reality" or "virtual products" do not have any physical structure. They are only existing in computers. For the observer the reality or the product is "existing in the mind, especially as a product of imagination" (American Heritage Dictionary). The term "enterprise" generally associates a bounded and durable object, consisting of people and buildings and basing on a legal framework.

  • Accordingly a virtual enterprise is an enterprise which is lacking some structural characteristics of real enterprises, but nevertheless functions like an enterprise in the imagination of the observer.


Virtual Enterprise

The terms Virtual Enterprise can be synonymous of Cyber Enterprise

because the (Sophocles, VISPO) Project objective is to offer advanced services specific of the Cyber Space by means of distributed computational simulation (VCs).


E-Business

Definizione IBM:Un approccio sicuro, flessibile e integrato alla creazione di un business dal valore aggiunto tramite la combinazione di sistemi e processi che gestiscono le operazioni primarie con la semplicità e la diffusione rese possibili dalla tecnologia di Internet


L’e-business comprende oltre all’e-commerce sia le applicazioni del FRONT END che quelle di BACK OFFICE

  • E-Business

  • E-Commerce +

  • Ridefinizione strategia competitiva

  • Ridisegno processi di business

  • Integrazione delle catene del valore dei Business Partners

  • Customer connection

  • Cultura aziendale

  • E-Commerce:

  • marketing

  • vendite

  • acquisti

L’e-commerce è solo uno

degli aspetti dell’e-business

E-Business


La catena del valore

La scomposizione dei processi aziendali, secondo la catena del valore dell’informazione individuata da Porter (1985), consente di isolare le singole attività rilevanti, individuare eventuali punti deboli all'interno delle stesse ed adottare le strategie idonee per il miglioramento delle stesse in una ottica di creazione del valore per il cliente finale.

Catena del valore tradizionale di Porter


La nuova catena del valore

L'azienda e-business supera questa concezione: la catena del valore non è più lineare e consequenziale, ma si sviluppa "a rete" e il valore creato trae origine dall'attività di più soggetti che operano e si coordinano grazie alle possibilità di interconnessione.La gestione efficace della catena del valore presuppone la condivisione in rete, a livello di distretto industriale, di alcuni processi aziendali fondamentali.

E’ centrata sull’evoluzione dei processi di comunicazione delle imprese


Processi collaborativi: EDI

EDI (Electronic Data Interchange): Interscambio elettronico, da computer a computer, di informazioni commerciali strutturate.Si basa sullo standard ANSIX12(USA) o UNEDIFACT(ISO) ma non utilizza tecnologie Web.

  • Pregi:

  • Metodologia efficace e sicura;

  • Semantica ben definita delle diverse relazioni di scambio tra le aziende, applicabile in qualsiasi settore commerciale e Paese.

  • Difetti:

  • Investimenti alti;

  • Ambiente di lavoro a mainframe.


Processi collaborativi: XML

  • XML (eXtensible Markup Language):

  • linguaggio adatto allo scambio di dati tra imprese, con una logica simile all’EDI;

  • non è una tecnologia proprietaria.

  • Usato in CEVI per definire il modelli dei VCs.

  • XML/EDI:

  • usare un messaggio EDI (secondo lo standard UN/EDIFACT) scritto in formato XML.


Standards

CEVI è stato progettato in accordo con i seguenti standards:

  • HTML;

  • XML;

  • XML/VOICE 2.0, MMI

  • usare il testo per ascoltare messaggio audio (W3C Consortium, 2004) scritto in formato XML.

  • ASP, JSP, JAVA, JDK 1.4.0, JMF 2.1;

  • MACROMEDIA FLASH MX

  • VMRL;


Il Progetto SOPHOCLES

Progetto SOPHOCLES

“System level develOpment Platform

based on HeterOgeneous models and

Concurrent LanguagEs for System

applicantions implementation”.

Scopo: raggiungere la validazione concettuale di metodologie, piattaforme e tecnologie che supportano l’integrazione e la programmazione, in ambiente distribuito, di sistemi complessi basati su Componenti Virtuali (VC) eterogenei.

VC:sono codici di simulazione che replicano il comportamento delle Intellectual Properties o IP (oggetti fisici come Controller, memorie flash, DSP, PLC, etc).

Multimedia Database integration

Multimedia DB

Provider’s DB

User DB

Web

Information flows among CE, Web, user and provider’s VC server. These information, coming from heterogeneous and distributed CE – databases, are managed to create the CE knowledge.


VC Server configuration

VCs, hosted on the provider’s machine, must be configured with:

  • Information (VC and connection links) about the model of the system the designer built (VC-net);

  • TCP-IP information about the machines hosting the VCs involved in the design.

  • c) Information about the SW component managing communication and simulation results.

  • Information (a) is derived by the XML file produced by the Ptolemy II environment

  • Information (b) and (c) are set by the CE through queries to specific databases.

User Registration

  • The user registration is a preliminary step that allows the user to access serveral Cyber Enterprise services;

  • The registration is user-profile modelled (End-user, Visitor, Customer, Company, etc);

  • Different user-profile  Different amount of information requested;

  • Different user profile  Different services allowed;

Provider Web Information set

  • Providers who desire to offer their simulation environment have to furnish to the Cyber Enterprise a set of information:

  • A VC card that specifies both general (Name, field of application, etc) and technical information (number of I/O ports with their AC specifics, compatibility with other VC, etc);

  • The IP addresses of the machine that hosts VCs;

  • How to locate the simulation result.

The CE will provide an application to allow communication between provider’s machine and CE server.


CE-Ptolemy II integration

The CE has a distributed architecture

Ptolemy II (Berkekey Univ.) is a stand-alone program

VEC

Ptolemy II has been integrated with an additional module (VEC- Vergil Enhanced Consolle) that allows direct communication between the client-machine (on which Ptolemy II is running) and CE machine (on which information about user, VC model and VC location are stored)

I moduli di CEVI: VCM (Virtual Component Manager)

  • Il Virtual Component Manager (VCM):

  • permette l’integrazione fra Attori, Componenti Virtuali, utente e processi coinvolti nella fase di simulazione;

  • è invocato tramite RMI da tutti i moduli della CE che richiedono l’accesso ai database (VEC, CEVI-JA, CM);

  • utilizza una gestione ottimizzata delle connessioni, realizzata mediante l’uso di un “pool” di connessioni attive (connection pooling).

CEVI-JA


I moduli di CEVI: CM (Communication Manager)

  • Il Communication Manager (CM) svolge una funzione fondamentale nelle comunicazioni tra i VC e la CE nella fase di simulazione.

  • Funzioni:

  • riceve da VCM lista VC da attivare con i relativi parametri in linguaggio XML;

  • mette in comunicazione tra loro i VC;

  • attende il risultato;

  • controlla situazione di errore e/o stallo;

  • spedisce il risultato alla CE (VCM/CEVI-JA).
