Obravnavan proces hladnega valjanja pločevine predstavlja enega pomembnejših postopkov predelave pločevine, ki je namenjen zmanjšanju debeline, izenačitvi debeline ter zagotovitvi ustreznih mehanskih lastnosti materiala. Za dosego stalne visoke kakovosti izdelka in maksimalne produktivnosti linije so nujne pravilne nastavitve in prilagoditve procesnih parametrov glede na trenutne procesne naloge. V okviru magistrske naloge se osredotočamo na razvoj priporočilnega sistema za podporo pri odločanju operaterjev v industrijskih procesih. Glavni cilj naloge je preveriti, ali je mogoče prenesti prakso priporočilnih sistemov, ki se običajno uporabljajo na področju trženja, tudi na področje industrijskih podporno odločitvenih sistemov. Namen takega sistema je izluščiti najučinkovitejše operaterske prakse, jih prenesti na manj izkušene operaterje in jih uporabiti za avtomatsko prilagajanje procesnih nastavitev trenutnim procesnim nalogam. Za demonstracijo uporabe razvitega sistema za podporo pri odločanju operaterja v industrijskem procesu smo razvili posebno orodje. To orodje je namenjeno operaterjem za prilagajanje parametrov recepta glede na značilnosti posameznega obdelovanca ter tehnologom za identifikacijo bolj primernih generalnih receptov za širšo paleto izdelkov, ki se proizvajajo. S pomočjo razvitega sistema je mogoče najti alternative in izboljšave v primerjavi s trenutno uporabljano prakso, ob upoštevanju preteklega znanja in izkušenj. Razvito operatersko orodje in pristopi preslikave priporočilnih sistemov niso omejeni na specifične lastnosti obravnavane valjavske naprave, kar omogoča prenosljivost in uporabo teh pristopov tudi v sorodnih proizvodnih procesih z ustrezno prilagoditvijo. Cold rolling of sheet metal is one of the most important processes in sheet metal processing, which is used to reduce the thickness, equalize the thickness and ensure the appropriate mechanical properties of the material. In order to achieve consistently high product quality and maximum productivity of the equipment, it is important to properly adjust and adapt the process parameters to the current process tasks. The focus of this thesis is on the development of a recommender system for operator decision support in industrial processes. The main goal of the thesis is to verify if the practice of recommender systems, commonly used in the field of marketing, can be transferred to the field of industrial decision support systems. The goal of such a system is to extract the most effective operator practices, transfer them to less experienced operators, and use them to automatically adapt process settings to current process tasks. A special tool has been developed to demonstrate the use of the developed decision support system in an industrial process. This tool is intended for operators to adjust recipe parameters according to the characteristics of the individual workpiece, and for technologists to determine more appropriate general recipes for a wider range of products to be manufactured. The developed system can be used to identify alternatives and improvements compared to current practice, taking into account previous knowledge and experience. The developed operator tool and recommender system approaches are not limited to the specific characteristics of the considered rolling mill, which allows transferability and application of these approaches also in related production processes with appropriate adaptation. |
