1 SCIRO - Bled /09/02 WP2 Functional Requirements and Architecture External Functional Analysis (D4) & Internal Functional Analysis (contribution to D5)

SCIRO - Bled /09/02 2 External Functional Analysis (D4) zA set of sequence diagrams has been reported in order to well understand: ythe processes where the F-Man system is supposed to be involved in, ythe roles of the external entities, ythe data exchanged. zThe following phases have been implemented: ydetermination of the external medium that constitute the environment where F-MAN is supposed to work, once it is implemented, ydetermination of the principal functions (17), ydetermination of the constraints (9), yvalidation of functions and constraints, ydetermination of the main characteristics of functions and constraints.

SCIRO - Bled /09/02 3 Internal Functional Analysis (contribution to D5) zSciro and Sigma/SNCF have performed two independent Internal Functional Analysis, starting from the same F-Man structure and from the result of D4

SCIRO - Bled /09/02 4 Internal Functional Analysis Main differences F8, F12, F13, F14 SciroSigma/SNCF zThe DPM performs delays/damages detection, each time it receives an event messages from the wagon or the OPM zThe DPM actualizes the database of future wagons location and availability zOnly in case of delay/damage, the DPM warns the AMM zThe AMM checks if the delay/damage is related to an empty/loaded or booked wagon zThe AMM informs the FM, the MM or the OM zThe DPM actualizes the database about wagon location and status taking into account information coming from the GS and the OPM zF8: The AMM analyses the database and warns about the difference of the current location and the foreseen one. In case of delay he informs the FM

SCIRO - Bled /09/02 5 Internal Functional Analysis F8 To update wagons allocation on the basis of real time data provided by the OPM and Wagons and of foreseen path and timetable (by the OPM), and to inform the FM in case of delay detection related to empty booked wagons F12 To inform the FM, the OM and the MM about damage on wagons F13 To inform the FM and the MM that wagons are arrived in workshop, taking into account event messages sent by the OPM and real time events sent by wagons F14 To update wagons allocation on the basis of the MM data about delay during maintenance in workshop and to inform the FM in case of delay detection related to booked wagons
