Abstract:
This research aims to increase the efficiency of medical device production under the condition that the production area is reduced. Currently, AAA products production by Push system as Batch production of 11 sub assembly processes, then stored as a work in process before sending to the main assembly process for assembly all the sub units together and send to the next process. The research methodology start from studying the current situation of production process about using areas, time and working methods then analyze the non-value added work and improve the production process with ECRS technique. After that, study the standard time of each process and using precedence diagram to design new production process to cellular production by applying line balancing technique with combine and rearrange working process of some sub assembly and main assembly by using 3 persons to produce AAA complete unit and set new standard time for cell. Which these production process will be work as Pull system and we design to approach One-piece flow production. The result of the research showed Production area decreased from 219 square meters to 111 square meters or decreased 49 percent. Work stations decreased from 15 stations to 10 stations. Workers were reduced from 30 persons to 27 persons or reduce 3 persons and the cycle time decreased from 652 seconds/unit to 574 seconds/unit or production efficiency increase from 5.52 units/person/hour to 6.27 units/person/hour or 12 percent increasing. For the areas that can reduce 108 square meters will use to support the production line of new products.
