Usled delovanja velikog broja neizvesnosti, kao što su faktori rizika, koji potiču iz
okruženja stvorila se potreba da se preduzeća posmatraju kao projektne organizacije.
Klasifikacija faktora rizika, kao i njihova identifikacija na nivou svake grupe,
izvršena je prema seriji standarda BS 6079.
Poznato je da su efektivnost realizacije tehničko-tehnoloških projekata i efektivnost
preduzeća u pozitivnoj korelaciji. Ocenjivanje tehničko-tehnoloških projekata sa aspekta
ranjivosti kao i preduzimanja odgovarajućih mera koje mogu da dovedu do smanjenja
ranjivosti projekata istovremeno dovodi i do povećanja efektivnosti preduzeća.
Mala i srednja preduzeća u razvijenim zemljama evropske unije ostvaruju prihod koji čini
polovinu bruto domaćeg proizvoda te se može zaključiti da poslovanje ove grupe preduzeća
usled delovanja faktora rizika može da dovede do velike ranjivosti goto cele privrede.
Respektujući sve gore iznete činjenice, problem ocenjivanja ranjivosti tehničkotehnoloških p...rojekata koji se realizuju u malim i srednjim preduzećima, koji je razmatran
u ovom doktorskom radu, je poslednjih decenija postao veoma interesantan kako za
istraživače tako i za domen prakse.
U ovoj doktorskoj disertaciji prateći preporuke iz literature predložena je metodologija
procene ranjivosti tehničko-tehnoloških projekata koja integriše izloženost,
osetljivost i statički adaptivni kapacitet. Procene ovih faktora ranjivosti postavljen
je kao problem grupnog odlučivanja. Donosioca odluka na nivou svakog preduzeća koje
predstavlja deo konzorcijuma su procene iskazivali pomoću unapred definisanih
lingvističkih iskaza koji su modelirani fazi brojevima.
Agregirane vrednosti osetljivosti, izloženosti i stadičkog adaptivnog kapaciteta su
izračunate primenom različitih metoda agregacije. Izbor operatora agregacije je
izabaran u zavisnosti od prirode razmatranog faktora ranjivosti.
Primenom predložene fazi metode može da se izračuna na egzaktan način ranjivost svake
faze tehničko-tehnoloških projekta na nivou konzorcija usled delovanja svake grupe
faktora rizika, respektujući više kriterijuma kao i njihove vrednosti.
Na osnovu izračunate vrednosti ranjivosti, projekt menadžeri mogu da preuzmu odgovarajuće
aktivnosti koje mogu da dovedu do smanjivanja ranjivosti čime se istovremeno povećava
efektivnost projekt menadžmenta.
U ovom doktorskom radu razvijen je softver za ocenu ranjivosti projekata koji je zasnovan
na predloženoj metodi.
Predloženi model je testiran i verifikovan na grupi od šest malih i srednjih preduzeća
koje čine konzorcijum u kojima je realizovan jedan zajednički tehničko-tehnološki
projekat.
Due to the large number of uncertainties, such as risk factors, which emanate from the environment,
there is a need for companies to be regarded as project organizations. Classification of risk factors,
as well as their identification at the level of each group, was performed according to the BS 6079
standard series.
It is known that the effectiveness of the realization of technical and technological projects and the
effectiveness of the company is in a positive correlation. Evaluating technical and technological
projects from the point of view of vulnerability and taking appropriate measures that can lead to the
reduction of vulnerability of projects simultaneously leads to an increase in the effectiveness of the
company it self.
Small and medium enterprises in developed countries of the European Union earn income which
accounts for half of gross domestic product, and it can be concluded that the ongoing of this group
of enterprises due to the effects of risk factors can le...ad to high vulnerability goto the entire economy.
Respecting all the above facts, the problem of assessing the vulnerability of technical and
technological projects implemented in small and medium enterprises, discussed in this doctoral
thesis, has become very interesting for the researchers and the domain of practice in recent decades.
In this doctoral dissertation, following the recommendations from the literature, a methodology for
assessing the vulnerability of technical and technological projects has been proposed, which
integrates exposure, sensitivity and static adaptive capacity. Estimates of these vulnerability factors
were set as a problem of group decision making. The decision-makers, at the level of each enterprise
that is part of the consortium, evaluate the estimates using predefined linguistic statements that
were modeled with fuzzy numbers.
The aggregated values of sensitivity, exposure and static adaptive capacity are calculated using
different aggregation methods. The selection of the aggregation operator was selected depending on
the nature of the vulnerability wich is considered.
By applying the proposed fuzzy method, vulnerability of each phase of technical and technological
projects at the consortium level due to the action of each group of risk factors can be calculated,
respecting multi criterias and their values.Based on the calculated vulnerability value, project managers can take appropriate actions that can
lead to the reduction of vulnerability, which simultaneously increases the effectiveness of project
management.
In this doctoral thesis software was developed for vulnerability assessment of projects based on the
proposed method.
The proposed model has been tested and verified on a group of six small and medium enterprises
that consist of a consortium in which a common technical and technological project was
implemented.
