Rationalization project of workplace for Hot-water Heater welding
Varjan, Matúš ; Heinl, Zdeněk (referee) ; Rumíšek, Pavel (advisor)
The aim of the thesis is to rationalize the water heaters welding area in Tatramat company - ohrievače s.r.o. The rationalization consists of three parts. The first part deals with the arrangement of the workplaces, the second part re-evaluates the monthly production planning. The third part describes in detail the production of one type, which based on simulations created in the simulation software Witness, compares the recorded time in company informartion system Orfert to the real production time in the operation. Each individual part offers optimization proposals and merging them into one unit, will create an efficient, transparent and economically value adding rationalization of the water heaters welding area.
