Formiranje familije mašine-delovi korišćenjem softvera ART-1 Simulator i FLEXY

Abstract

Tehnološki sistemi bazirani na konceptu grupne tehnologije imaju prednosti pre svega u domenu fleksibilnosti. U radu je, uvođenjem nove tehnike klasterovanja, analiziran odnos familije mašine-delovi unutar tehnološkog sistema i relevantnih tehnoloških procesa, s obzirom na tehnološku sličnost delova koji čine familiju. Takav tehnološki sistem se organizuje u grupe mašina, formirajući ćelije, uz obezbeđenu maksimalnu proizvodnost delova. Rad prezentira novu primenu ART-1 veštačke neuronske mreže u analizi tehnološke sličnosti i nudi modifikovan bazični pristup u cilju povećanja efikasnosti procedure klasifikovanja. Razvijeni softveri ART-1 Simulator i FLEXY su korišćeni u postupku formiranja familija, shodno reafirmisanom konceptu projektovanja grupne tehnologije.

Group technology based manufacturing systems offer the advantages of flow production as well as the production flexibility of batch manufacturing. In this paper, by employing new clustering techniques, the part-machine spectrum of the manufacturing system and the relevant manufacturing process are analyzed according to design, similarity of machining and product flow. This leads to an organization of the production system into self-contained and self-regulating groups of machines called machine cells. Each machine cell undertakes a maximal production of a family of parts having similar manufacturing characteristics. This paper carried out the ART-1 neural network approach in the analysis of the manufacturing similarity, and modified the basic approach to increase the efficiency of the classification procedure. Developed program packages ART-1 Simulator and FLEXY are used to create part families and machine cells within the group technology design.
