Creato of uversal mathematcal model whch wll cosder all features of securty obect ad geerate the optmum decso o elmato of emergecy stuatos of ay type ad ay place, s the relevat task demadg deep study of questos ot oly detecto, but also optmum respose to arsg stuatos. Keywords - Securty Obect, Vector Aalyss, Decso- Makg Support, Evet Regstrato NTRODUCTON For esurg protecto ad a securty t s ecessary to solve a comple problem of a choce, stallato ad operato of securty hardware. The obect securty system s teded for use the bakg, credt ad facal ad other large sttutos havg brached frastructure ad dffcult maagemet. The developed system has to easly ad wth the smallest chages the estg software SW) to be tegrated to a automated cotrol system for securty obect []. The system has to keep surely the obectve oural of the evets whch have occurred durg watch, whch the persos who are keepg watch ca't correct. t has to provde coecto of sesors of dfferet types ad vdeo cameras, to cope from a workplace of the operator by meas of the computer or remotely []. Necessary codto of creato of obect securty systems s mplemetato of the followg geeral requremets: a) tegrato to a automated cotrol system for establshmet; b) esurg dagosg of emergecy stuatos ad rapd respose to ther emergece. Thus probably two cases: ) the geeral sgs of a stuato ca be descrbed by meas of estg model, however developmet of a stuato ca happe the varous drectos, to forecast whch t s uambguously mpossble; ) the geeral sgs of a stuato do't ft to estg model of fuctog of the securty obect; c) possblty of cofgurg ad self-cofgurg of obect securty system; d) the automated regstrato of evets o securty obect ad operatoal maagemet of work of that, partcular hs employees, formato securty from uauthorzed access []. TASK DEFNTON codtos whe emergecy stuatos ca arse varous parts of orgazato ad brg varous degree of damage, t s ecessary to cosder that factor at desg of system that the securty obect represets large orgazato whch separate elemets of system departmets, servces, etc.) are dstrbuted space. Besdes, t s ecessary to cosder that obect securty systems ca be developed two aspects: a) orgazato already ests ad ts spatal orgazato should't chage. ths case a task of the developer - moderzato re-egeerg) of estg system of safety of obect; b) establshmet s't costructed yet or ts archtectural recostructo or movemet of separate elemets of system wth securty obect s possble. ths case the problem of creato of securty system eteds o sythess of spatal ad orgazatoal structure of securty obect. Takg to accout stated, wth the real work the problem of creato of system of regstrato of evets s formulated as follows []. t s set: set of dvsos ad ther spatal arragemet the terrtory of securty obect; workg hours of dvsos; levels of access to rooms; requremets to dcators of qualty of system safety of people ad esurg safety of property of securty obect); ecoomc dcators of developmet ew or moderzatos of estg system. t s ecessary to develop: model ad algorthm of fuctog of a subsystem of automatc regstrato of evets securty system of corporato at varous modes of ts fuctog. such geeral statemet the soluto of a task dffcult for the followg reasos: a) lack of tal formato: some characterstcs of system ca be defed oly the course of ts operato; b) evoluto developmet of the system, partcular ot stable character of system fuctog modes. The specfed dffcultes ca be overcome wth methodology of the system aalyss by meas of decomposto of a tal problem o a lttle codtoally depedet sub problems whch are tur dvded to complees of tasks, tasks, subtasks, etc. Cosderg the above, the real work the followg herarchy of problems of sythess of evet regstrato system s accepted at creato of securty system of corporato) see Fg. ):

Automatc detectg of a evet s made by meas of the correspodg hardware-software comple. formato that the emergecy stuato of a certa category s detected by the automated system, s formed the form of a vector.). Ths vector has a form of a matr whch colums correspod to room umber, ad les - categores of a possble emergecy stuato evet). The problem of system of regstrato cossts scag ths matr formed automatcally by evet detectg system. readg of ths colum of a matr for the purpose of recevg a code of a evet s made. The task of the program of detectg that case cossts defg, whether equally the receved -bt umber to zero or ot. f s't preset, the system passes to readg of a codto of the followg room of corporato. f the code s't equal to zero, the system carres out sedg the message o emergecy stuato ad trasfers cotrol to the followg module of the program - to defto of degree of evet mportace. rrespectve of result of codto cotrol of the approprate room the system cotues to sca a matr.) tll the ed whe rooms ay more dd't rema). Ths scag allows to fd ay quatty of emergecy stuatos whch could arse corporato securty obect). For defto of degree of mportace of a evet the result of operato of the evet detectg program module ad earler developed elemets of model used system of regstrato of evets s used. After the evet the approprate premse of corporato s detected, we get a umber of the room ad a evet code. The operatg mode of the room s a bt of formato. For defto of degree of mportace of a evet from the pot of vew of a room operatg mode, t s eough to supervse bt of a operatg mode of the room ad to use t for defto of degree of mportace of a stuato. We accept that case the room s a protecto mode, mportace of a stuato doubles, that s the fal crtero has to be multpled by. Presece at the room of people s used the same way, as well as a room operatg mode: f doors there are people, the crtero of mportace doubles. Thus, to defe degree of mportace of a evet, t s ecessary a formula.8) to add two addtoal coeffcets, descrbed earler.
