Assembly line balancing is a strategic process that involves allocating tasks among workstations to optimize efficiency and throughput. In this case, an assembly line with 17 tasks must be balanced, considering specific task durations, total work time, and throughput goals. The critical parameters include the longest task duration, total task time, operating time per day, and desired output rates.

First, determining the minimum and maximum cycle times is essential. The minimum cycle time is dictated by the longest task, as no station can process tasks faster than its slowest task. Given the longest task is 2.4 minutes, the minimum cycle time should be at least this duration to process that task. The maximum cycle time is governed by the total available time divided by the number of units to be produced per day. With a total task time of 18 minutes applied over a 450-minute workday, the maximum cycle time can be approximated by dividing total available time by the number of units needed, or by considering constraints such as task dependencies.

Next, the range of daily output reveals the theoretical limits based on the minimum and maximum cycle times. The maximum possible production occurs when each cycle is as short as the minimum cycle time, leading to the highest number of units per day. Conversely, the minimum output is limited by the maximum cycle time, producing fewer units over the same operational period.

Calculating the minimum number of workstations involves dividing the total task time by the cycle time that ensures adequate throughput. This ensures that all tasks can be assigned without excessive idle time, respecting task precedence and capacity constraints.

Selecting a cycle time to achieve a specific daily output, such as 125 units, requires dividing the total available operational time by the desired number of units, resulting in a suitable cycle time. This calculation assists in designing an efficient assembly line configuration that matches production goals.

Finally, evaluating the output potential at different cycle times—9 minutes and 15 minutes—provides insight into the line’s productivity limits. Shorter cycle times generally yield higher production but may introduce complexity in task assignment, while longer cycle times reduce throughput but may simplify balancing tasks and reduce costs.

Through these calculations, manufacturers can optimize assembly line performance by balancing tasks effectively and aligning operational parameters with production objectives. Such analysis ensures resource utilization efficiency, minimizes idle time, and enhances overall productivity.
