Abstract
Ohranjanje konkurenčnosti zahteva širitev palete izdelkov, s čimer zadovoljimo spreminjajoče se potrebe in zahteve kupcev. Učinkovitost in robustnost konstrukcijskega procesa individualnega proizvoda mora biti zagotovljena z ustreznim sistemom informacijske in metodološke podpore ter reorganizacijo procesnih aktivnosti. Strategija razvoja izdelkov mora temeljiti na identifikaciji zahtev kupcev, vgrajeni v koncept modularnosti fizikalnih funkcij, kar omogoča izvedbo individualiziranega izdelka. To neizogibno narekuje prehod v razvoj prilagodljivih, modularnih izdelkov. Modularnost izdelka je dosežena s kombiniranjem različnih modulov, robustno povezanih preko skupne platforme. To je osnova za vzpostavitev pametne tovarne, znotraj katere dinamični poslovni in inženirski procesi omogočajo spremembe v dizajnu in proizvodnji v zadnjem trenutku, kar omogoča agilen odziv v primeru kakršnih koli sprememb. V pričujočem delu je predstavljen model za preobrazbo razvojno-konstrukcijskega procesa v individualni proizvodnji v skladu z agilnimi in vitkimi načeli. Povečanje robustnosti procesa je bilo doseženo z uvedbo povečane spremenljivosti procesa in izdelka ter prehodom v pametno strategijo načrtovanja, ki temelji na agilnem izvajanju načrtovalnih ciklov. Predstavljeni model je bil potrjen z obsežno študijo v realnem industrijskem okolju. Izkazani učinki so potrdili praktično uporabnost modela, njegova posplošena oblika pa omogoča njegovo neposredno implementacijo v podobna industrijska okolja, znotraj katerih individualiziranim izdelkom povečamo dobičkonosnost zaradi dviga kakovosti in krajših razvojnih časov.

Title:Method for increasing of robustness of the engineering design process in individual production
Abstract:
Increasing competition has forced companies to expand their product range to meet changing customer needs and requirements. The efficiency and robustness of the design process of an individual product must be ensured by an appropriate system of information and methodological support and the reorganization of process activities. The product development strategy must be based on the identification of customer requirements, embedded in the concept of modularity of physical functions, which enables individual product realization. This inevitably requires a transition to development of adaptable, modular products. Product modularity is achieved by combining different modules robustly connected through a common platform. This is the basis for setting up a smart factory, within which dynamic business and engineering processes enable last-minute design and manufacturing changes, allowing for an agile response in the event of any changes. This thesis presents a framework for transforming the development and design process within highly individualized business environment in accordance with agile and lean principles. Process robustness has been increased through the introduction of enhanced process and product variability and through the implementation of concurrent and smart design strategies. The presented framework has been validated by an extensive case study in a real industrial environment. The significant effects have confirmed the practical applicability of the proposed framework, while its generalized form allows its direct implementation into similar industrial environments, within which individualized products maximize their profitability due to their higher quality and shorter lead times.

Keywords:development and design process, individualized production, lean design, agile design, robustness, modularity, digital twin
