Sistem delotokov kot informacijska podpora podjetjem, dejavnim na področju trajnostne gradnje : doktorska disertacija

König, Matija (author), Stankovski, Vlado (mentor), Šelih, Jana (comentor)

Doktorska disertacija obravnava področje dostopnosti informacij, pomembnih za odločanje o izbiri storitev in proizvodov pri prenovi stavbe. Te so pogosto neurejene in razpršene po celotnem spletu ter zapisane v različnih formatih. Posledično je lahko iskanje želenih informacij zelo zamudno in nepregledno. Informacije lahko zajamemo v delotoku, ki predstavlja zaporedje povezanih storitev, izvajanih v primerno orkestriranih korakih. Osnovna hipoteza trdi, da lahko model informacijskega sistema delotokov zajame visoko stopnjo ključnih informacij in znanj na področju trajnostne gradnje in načrtovanja ter kot tak predstavlja primerno informacijsko podporo gradbenim podjetjem in investitorjem. Potrebe po informacijski podpori ugotavljamo s pomočjo raziskave med ključnimi deležniki na področju gradbeništva. Rezultati izvedene raziskave razkrivajo velike potrebe po dostopu do urejenih informacij in kažejo na veliko pripravljenosti deležnikov za sodelovanje ter medsebojno deljenje informacij. Izdelan je pregled obstoječih rešitev in dognanj na omenjenem področju. Predstavljen je trajnosten pogled na stavbe s pregledom najbolj razširjenih in aktualnih pristopov trajnostnega ocenjevanja stavb, ki razkriva razlike pri pripisovanju teže posameznim trajnostnim vidikom. V nadaljevanju izdelamo pregled stanja slovenskega stavbnega fonda, ki razkriva, da je velika večina stavb potencialno potrebnih prenove. Predstavljene so tudi semantične tehnologije, ki omogočajo izdelavo naprednih informacijskih sistemov in ki jih zato uporabimo v nadaljnjem delu. V nadaljevanju dela je predstavljen razvoj prototipa informacijskega sistema, ki temelji na delotokih. Opisana je zasnova arhitekture informacijskega sistema, model sprejemanja odločitev in razvita ontologija, ki podpira zapis informacij v delotoke in hrambo informacij v pripadajoči podatkovni bazi OWL/RDF. V zaključnem delu je predstavljena validacija prototipa informacijskega sistema, ki kaže, da smo uspeli zadostiti opredeljenim zahtevam. Postavljena hipoteza je torej potrjena.

• Title: A workflow system as an information support to companies operating in the area of sustainable construction

Abstract

The research presented in this thesis is concerned with the accessibility of information on the world web, crucial for the decision making process regarding products and services required for building refurbishment. This information is often dispersed, poorly structured and written in various formats. As a consequence, information search on the web can be extremely time-consuming and difficult to carry out. The information can be sequenced in a workflow consisting of a series of interconnected services which are executed in orchestrated steps. The research hypothesis postulates that the workflow information system model is able to encompass a large proportion of key information and knowledge from the sustainable construction field. As such, it represents efficient information support to potential clients and construction contracting companies. Information support requirements of various stakeholders from the construction sector were identified by using a survey. The obtained results exhibit a clear need for structured information, as well as a significant willingness of stakeholders to share the information. An overview of the existing solutions and accomplishments in sustainable construction is presented. The concept of sustainability assessment is presented, along with an overview of the most frequently employed approaches for the sustainability assessment of buildings, which reveals differences in assigning relative importance to individual sustainability aspects. An overview of the Slovenian residential building fund is carried out. It shows that the majority of residential building stock is in need of refurbishment. Further, semantic technologies that enable the establishment of advanced information systems are presented. The second part presents the development of a workflow-based prototype information system. The design of the information system architecture is presented, together with the decision making model and the ontology that supports information recording into workflows and data storage into the OWL/RDF database. The validation of the information system is presented in the concluding part. It is shown that the system requirements defined in the beginning of the research were achieved; the initial hypothesis is therefore confirmed.
