Abstract:	V disertaciji predlagamo od jezika ter notacij za modeliranje poslovnih procesov neodvisen metamodel za formalno specifikacijo funkcionalnih zahtev dinamičnega izbiranja storitev v modelih poslovnih procesov. Predlagani metamodel naslavlja konfigurabilno dinamično izbiranje storitev na podlagi vsebine in konteksta. S prednostmi tovrstnega pristopa metamodel zagotavlja večjo fleksibilnost modeliranih procesov, hkrati pa zmanjšuje njihovo kompleksnost. Izvedljivost in učinkovitost metamodela preverimo z njegovo vključitvijo v de facto standard za modeliranje poslovnih procesov Business Process Model and Notation 2.0, tako da predlagamo razširitev omenjene specifikacije. Za potrebe opisovanja vmesnikov v točkah dinamičnega izbiranja storitev predlagamo rešitev za podporo definicijam XML Schema strukturnih omejitev, ki so odvisne od posameznih primerov uporabe (t.j. od kandidatnih storitev). V ta namen predlagamo razširitve specifikacije XML Schema, ki so tudi širše uporabne. Omogočajo namreč definicijo tipov in elementov, ki se uporabljajo v različnih primerih uporabe s specifičnimi strukturnimi omejitvami. Na ta način predlagane razširitve omogočajo minimalno število potrebnih tipov za modeliranje neke domene. Učinkovitost metamodela pokažemo skozi merjenje kompleksnosti modelov realnih poslovnih procesov z namenskimi metrikami. Predlagamo tudi novo, s storitveno usmerjeno arhitekturo kompatibilno metodo za merjenje funkcionalne velikosti modelov poslovnih procesov. V ta namen adaptiramo metodo COSMIC na domeno upravljanja poslovnih procesov. Predlagano metodo nato uporabimo za preverjanje doprinosa predlaganega metamodela k zmanjševanju potrebnega napora za implementacijo modeliranih poslovnih procesov, s čimer ugotovitve o učinkovitosti predlagane rešitve še dodatno podkrepimo.

Title:	MODELING FUNCTIONAL REQUIREMENTS FOR DYNAMIC SERVICE SELECTION IN BUSINESS PROCESS MODELS
Abstract:	In the dissertation, we have proposed a meta-model for formal specification of functional requirements for dynamic service selection in business process models. The meta-model is independent of business process modeling languages and notations. It addresses configurable content- and context-aware dynamic service selection. By leveraging the benefits of this approach, the meta-model assures greater flexibility of the modeled processes and reduces their complexity. We have verified the feasibility and effectiveness of the meta-model by including it into the de facto standard for business process modeling Business Process Model and Notation 2.0. We have achieved this by proposing a set of extensions to this standard. For service interface descriptions of dynamic selection points within process models, we have developed a solution that offers use case-specific definitions of XML Schema structural constraints. This solution is useful in broader scenarios since it supports definitions of types and elements that can be used in different use cases, each with its own set of specific structural constraints. This enables design of XML Schema documents with minimal number of types needed for modeling a specific domain. We have shown the effectiveness of the meta-model through the complexity measurement of real world business process models using relevant metrics. We have proposed a new, service oriented architecture compatible method for functional size measurement of business process models. For this purpose, we have adapted the COSMIC method to the business process management domain. We have used the adapted method for checking the effect of the meta-model on the needed effort to implement the modeled business processes. This way we have verified the findings regarding the effectiveness of our proposed solution.
