Abstract
The purpose of this paper is to demonstrate a productivity improvement through waste reduction and line balancing. One of the obstacles of a manual assembly line nowadays is an awkward line design with over manpower, a lot of wastes, and low balance efficiency. As a result, the production line may not satisfy customer demand and ends up with low production line efficiency. This is due to the fact that this type of production line is operated by human and the customer demand or requirements are frequently fluctuated. Human workers are prone to make mistakes, inefficient, and unorganized. Thus, the major causes of production line down time are discussed with suggestion of remedy actions to improve the productivity. In addition, calculation of line balancing is demonstrated. One of the actual manual assembly lines will be used as a case study. It is found that after improvement line balance efficiency is increased from 46.49 to 86.66 percent with the productivity improvement of 159 percent.
