20.500.12556/RUL-187589 Prototip spletne aplikacije za obdelavo povpraševanj za dobavo električne energije Prototype of a web application for processing electricity supply inquirie Na sproščenem trgu z električno energijo lahko odjemalec prosto izbere dobavitelja, vendar so ponudbe med seboj slabo primerljive, dobavitelji pa povpraševanja pogosto obdelujejo ročno, po elektronski pošti in v preglednicah. Diplomska naloga predstavlja razvoj spletne aplikacije, ki povpraševanje zajame v strukturirani obliki, ga posreduje več dobaviteljem hkrati in podpre celoten postopek obdelave do sklenitve pogodbe. Zahteve smo zajeli z modelom primerov uporabe v orodju PowerDesigner in iz njega izpeljali podatkovni model ter vloge uporabnikov: stranka, tržnik, vodja tržnikov in administrator. Aplikacija je izdelana v okolju Node.js z ogrodjem Express in podatkovno bazo SQLite. Osrednji prispevek je model porazdeljene obravnave, pri katerem isto povpraševanje prejme več konkurenčnih dobaviteljev, vsak pa ga obravnava ločeno in ne vidi obravnave drugih. Rešitev podpira tudi nalaganje skeniranih računov, evidenco vezave odjemnega mesta, obveščanje v živo s tehniko server-sent events ter izvoz podatkov v obliki CSV in XLSX. Delovanje smo preverili s samodejnimi testi na ravni strežnika in s testi v brskalniku. Rezultat je delujoč prototip, ki pokriva vse modelirane primere uporabe in pokaže, da je predlagani model izvedljiv ob doslednem ločevanju podatkov med konkurenti. In a liberalised electricity market consumers are free to choose their supplier, yet offers are hard to compare and suppliers often handle incoming inquiries manually through e-mail and spreadsheets. This thesis presents the development of a web application that captures an inquiry in a structured form, forwards it to several suppliers at once, and supports the entire handling process up to the conclusion of a contract. Requirements were captured in a use case model built in PowerDesigner, from which the data model and the user roles were derived: customer, sales agent, sales team leader and administrator. The application is implemented in Node.js using the Express framework and an SQLite database. The main contribution is a distributed handling model in which the same inquiry is received by several competing suppliers, each processing it separately and without visibility of the others’ work. The solution also supports uploading scanned bills, tracking the contractual lock-in period of a metering point, live notifications using server-sent events, and data export to CSV and XLSX. The solution was verified with automated server-side tests and browser- based tests. The result is a working prototype covering all modelled use cases, showing that the proposed model is feasible provided that data separation between competitors is strictly enforced spletna aplikacija upravljanje povpraševanj trg z električno energijo primeri uporabe web application lead management electricity market use cases true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2026-09-11 14:25:26 2026-09-11 14:25:34 2026-09-14 03:45:17 0000-00-00 00:00:00 2026 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 39071 Jarc_Primoz_-_Prototip_spletne_aplikacije_za_obdelavo_povprasevanj_za_dobavo_elektricne_energije.pdf Jarc_Primoz_-_Prototip_spletne_aplikacije_za_obdelavo_povprasevanj_za_dobavo_elektricne_energije.pdf 1 ED2C1225553A55AA8BA98B56E89A6B2B f18b60c972b85ed13bda2ad97c6decb8d756213c931ce5b8fe25b4d2822356c8 dc6551d9-addb-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=247275 Fakulteta za računalništvo in informatiko 0 0 0
