Utorak, 28.04.2015. u 14:15, soba 301f, MI SANU: dr Vjekoslav Bobar, Uprava za zajedničke poslove republičkih organa, Vlada Republike Srbije

INTEGRISANI FUZZY PRISTUP ZA REŠAVANjE PROBLEMA IZBORA PONUĐAČA U PROCESU ELEKTRONSKE JAVNE NABAVKE

Apstrakt: Cilj ovog rada jeste da ukaže na mogućnosti unapređenja donošenja odluke o izboru ekonomski najprihvatljivijeg ponuđača u procesu elektronske javne nabavke (e-nabavke) gde postoji veliki broj ponuđača, a izbor najprihvatljivijeg između njih vrši se na osnovu većeg broja kvalitativnih i kvantitativnih kriterijuma. U ovom slučaju, unapređenje izbora ponuđača može se izvršiti primenom integrisanog fuzzy pristupa gde se vrši određivanje vrednosti pridruženih izlaznih promenjivih koje odgovaraju težinama kvalitativnih kriterijuma koje pripadaju fuzzy skupu putem defazifikacije, odnosno izbora jedne vrednosti izlazne kvalitativne promenjive uz kvantifikovanje iste i upoređivanje sa kvantitativnim kriterijumima. Za primenu integrisanog fuzzy pristupa u radu je razvijen fuzzy sistem za podršku odlučivanju (FSPO) čiji su benefiti i efikasnost primene prikazani na rešavanju slučaja javne nabavke u državnom organu Republike Srbije.

TOWARDS QUANTITATIVE MODELING OF RELIABILITY FOR SUSTAINABLE CRITICAL INFRASTRUCTURE: CHALLENGES AND ADVANCES

Abstract:
Critical infrastructure systems are increasingly reliant on cyber infrastructure that enables intelligent real-time control of physical components. This cyber infrastructure utilize environmental and operational data to provide decision support intended to increase the efficacy and reliability of the physical system and facilitate mitigation of failure. Correctly implemented, the ultimate result of these efforts is more sustainable use of non-renewable resources and reduction of environmental impact. However, realistic imperfections such as corrupt sensor data, software errors, or communication outages can cause failure in an otherwise functional physical infrastructure, defying the purpose of intelligent control. As such, justifiable reliance on cyber-physical critical infrastructure is contingent on rigorous investigation of the effect of intelligent control, including modeling and simulation of failure propagation within the cyber-physical infrastructure. We discuss challenges in and recent advances towards development of quantitative models and accurate simulation methods for cyber-physical critical infrastructure systems, with focus on the reliability of smart grids and intelligent water distribution networks.

ENERGY-EFFICIENT ALGORITHMS FOR DATA RETRIEVAL FROM INDEXED PARALLEL BROADCAST CHANNELS

Abstract:
Constraints on the energy, bandwidth, and connectivity of mobile devices complicate the timely and reliable access to public data. Energy is often the most stringent constraint, necessitating techniques that facilitate operation in energy-saving modes. Broadcasting, typically over parallel channels, has proven to be an effective method for dissemination of public data to mobile devices. However, the employment of parallel channels introduces challenges associated with channel switches and conflicts due to the concurrent accesses to multiple data items that ultimately increase energy consumption and response time. The detrimental effects on energy consumption and response time can be alleviated by scheduling the retrieval of data items in an order that reduces the number of passes over the air channels and channel switches between the parallel channels.

This research, proposes several scheduling algorithms that achieve the aforementioned objectives.  To further improve energy consumption and response time, the scope of our scheduling algorithms has been enhanced by replication of popular data items. The proposed scheduling algorithms, both with and without replication, have been simulated and simulation results are presented and analyzed. These results show that the proposed scheduling algorithms, compared to some heuristic based methods, have greater impact in reducing the energy consumption and response time. This reduction is shown to be more pronounced with replication of data items.

Predavanje Moderne Web i Front-end tehnologije

Centar za razvoj karijere i savetovanje studenata Univerziteta u Beogradu u saradnji sa kompanijom "Youngculture d.o.o" organizuje predavanje na temu „Moderne Web i Front-end tehnologije“. Predavanje će se održati u petak 24. aprila od 11.30 do 14h, na Elektrotehničkom fakultetu Univerziteta u Beogradu, u sali 59.

Nastavlja se druženje sa zaposlenima iz kompanije "Youngculture". Ovog puta će vas Senior Software Engineer Žarko Šušnjar uz kratak osvrt na istoriju razvoja interneta, web strana i aplikacija, upoznati sa tehnologijama, tehnikama i rešenjima koja su dovela do onih koje se koriste danas.

Kako se Front-end tehnologije menjaju iz meseca u mesec, vrlo je važno poznavanje nekadašnjih rešenja i njihovih dobrih i loših osobina koje su dovele do stvaranja novih, koje će, opet, zbog svojih mana biti zamenjena u bliskoj budućnosti.

Učesnici će imati priliku da čuju više o razvoju modernih korisničkih interfejsa web aplikacija, kako su Front-end inženjeri postali danas veoma traženi da tržištu rada, zašto je front-end razvoj mnogo dinamičniji i zanimljiviji od razvoja web servisa ili baza podataka i kako uvek biti u toku i ostati konkurentan na tršištu rada.

Predavanje je prvenstveno namenjeno studentim završnih godina i diplomiranim studentima Elektrotehničkog, Matematičkog i Fakulteta organizacionih nauka, ali i drugima zainteresovanim za razvoj karijere u oblasti informacionih tehnologija.

Ovo je drugo u nizu predavanja koji se realizuje u saradnji sa kompanijom "Youngculture d.o.o" tokom 2015. godine na fakultetima u sastavu Univerziteta u Beogradu u okviru programa Centra za razvoj karijere Univerziteta u Beogradu "Lekcije iz prakse".

Program "Lekcije iz prakse" predstavlja ciklus predavanja, radionica i drugih aktivnosti koje se realizuju tokom godine u saradnji sa poslodavcima – korisnicima usluga Centra. Zamišljen je tako da uvaži interesovanja studenata i diplomaca pojedinih fakulteta i omogući im da u neposrednom kontaktu sa različitim poslodavcima dobiju važne savete i smernice koje će im olakšati proces zapošljavanja i uvođenje u svet rada.

Obavezno je prijavljivanje zbog ograničenog broja mesta. Molimo popunite upitnik za prijavu na linku:
