Productivity Analysis in Assembly Department Using Objective Matrix (Omax) Method in Labor Intensive Manufacturing
Keywords:Productivity, Performance, Objective Matrix (OMAX), Productivity Index
Productivity has become a holistic target in any manufacturing company. Performance evaluation for production areas in manufacturing should be measure by productivity index that already determined in company goals and targets. Currently, the productivity index has been measured by simple calculation, which only considering production result, manpower and working hours. Those calculations still cannot meet management desire about real productivity itself. Management needs productivity also considering some other performance, those are including quality rate, rework rate, manpower, working hour, production result, energy usage, and compliance with the schedule as input. This desire was mentioned in a company mission to be world-class manufacturing. A well-known method as an objective matrix would be used for measuring the productivity index in the company. There would be a different rank of productivity after considering all of the mentioned items when compared with the currently used method. Production could be bigger than other month but on the other hand quality rate and rework, the rate was dropped. Than rank for productivity index in this company would be more complex and could be used as a raw model of productivity measurement internally or externally.
