Application of semantic technology for calculation of welding time in the development of new products

Abstract

Preliminary communicationDetermining the time of execution is very important in the early stages of each project (e.g. making offers, design phase etc.), especially in the stage of planning. This paper presents our approach to estimating the welding time for the purposes of planning the manufacturing processes. The approach is based on the knowledge of welding experts from the Nieros metal d.o.o. company and standards of welding (international and internal). An expert system was developed based on semantic web technologies for calculating the welding time in the product design phase and it is strongly integrated with the main ERP system of the Nieros metal d.o.o. company. Test results are presented at the end of this article.

Ovaj rad predstavlja naš pristup procjeni vremena zavarivanja u svrhu planiranja proizvodnog procesa. Pristup se temelji na znanju stručnjaka za zavarivanje iz društva Nieros metala d.o.o. i na standardu za zavarivanje (međunarodni i unutarnji). Ekspertni sustav je razvijen na temelju semantičkih tehnologija za izračunavanje vremena zavarivanja u fazi projektiranja proizvoda. Sistem je snažno integriran sa glavnim ERP sustavom društva Nieros metala d.o.o. Rezultati eksperimenta su prikazani na kraju ovog članka.
