2 Facility layout Process terminology Cycle time: Average time between completions of successive units. Bottleneck: Factor that limits production. Slowest operating component in the production line. Capacity: Measure of output per unit time when fully busy. (typically measured as reciprocal of cycle time) Capacity utilization: Measure of how much output is achieved with respect to the total capacity available. Throughput time: Time taken to complete a process from arrival to exit. Sum of critical path operations plus waiting time in queue.

3 Assembly line balancing Typically, sequence of tasks required to assemble a product is dictated by its design. However, for many assemblies that consist of a large number of tasks, there are a large number of ways to group tasks together into individual workstations while still ensuring the proper sequence of work. Assembly line balancing is a technique to group tasks among workstations so that each work-station has, ideally, the same amount of work.

4 Assembly line balancing Example: if it took 90 seconds to assemble a pen, and the work was divided evenly among three workstations, then each workstation would be assigned 30 seconds of work content per unit. Basic assumptions: No idle time per workstations; and the output of the first workstation immediately becomes input to the next workstation. In the current example, there are no bottleneck workstations, and the flow of pens through the line is continuous.

5 Assembly line balancing Objective of assembly line balancing is to minimize the imbalance among workstations while trying to achieve a desired output rate. So either, one can minimize the number of workstations for a given production rate or maximize the production rate for a given number of workstations. Though typically carried out at the design stage of the
