In most real-world environments, production scheduling is an ongoing process where the presence of a variety of unforeseen disruptions is usually inevitable, and continually forces reconsideration and revision of pre-established schedules. Many of the approaches developed to solve the problem of production scheduling are often unfeasible in real-world, and near-optimal schedules with respect to the estimated data may become obsolete when they are released to the production lines or shop floor. This paper outlines the impact of unforeseen disruptions that affect manufacturing systems during production, and being able to cope or react to this determines a company's output and profitability. The theories of multi-factor productivity and line balancing are employed to determine how disruptions affect productivity output and the result reveals that when disruptions occur continuously with time, the total productivity output decreases as time goes on and, on the other hand, total production time increases and requires more resources to meet the planned capacity demand (PCD).
