4 Virtual district Internet-based Service PlatfOrm 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.

5 Virtual district Internet-based Service PlatfOrm 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). Virtual Enterprise

6 Virtual district Internet-based Service PlatfOrm 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

8 Virtual district Internet-based Service PlatfOrm 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. Produz ione Logisti ca entrata Logisti ca uscita MktgServizi Catena del valore tradizionale di Porter

9 Virtual district Internet-based Service PlatfOrm 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.

12 Virtual district Internet-based Service PlatfOrm Modello dell’impresa virtuale Un’Impresa Virtuale manca di una caratterizzazione fisica e strutturale tipica di un’impresa reale, ma tuttavia funziona come essa nell’immaginazione dell’osservatore.

13 Virtual district Internet-based Service PlatfOrm Modello dell’impresa virtuale ImpiegatiClienti PartnersFornitori Modello tradizionale Impiegati PartnersFornitori Clienti Modello relazionale Informazioni E’ centrata sull’evoluzione dei processi di comunicazione delle imprese

14 Virtual district Internet-based Service PlatfOrm 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.

15 Virtual district Internet-based Service PlatfOrm 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.

16 Virtual district Internet-based Service PlatfOrm 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;

18 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).

78 Virtual district Internet-based Service PlatfOrm 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 CM VCM VEC

79 Virtual district Internet-based Service PlatfOrm 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). CEVI-JA CM VCM VEC

80 Virtual district Internet-based Service PlatfOrm I moduli di CEVI: CEVI-JA La Cyber Enterprise Visual Interface – Java Applet è il pannello operativo a disposizione dell’utente per interfacciarsi con la Cyber Enterprise. Mediante CEVI-JA l’utente può: accedere alle risorse (Componenti virtuali acquisiti, i modelli di simulazione costruiti, ecc); configurare i VC in real –time, per mezzo di area di scripts; avviare la simulazione; ricevere il risultato della simulazione.
