2. Example of Line Balancing: Step 2: Determine Cycle Time Question: Suppose we only have demand for 3 units per hour. What would our cycle time have to be? Answer: Therefore, the maximum task time allowed in a single station is 20 minutes

3. Example of Line Balancing: Step 3: Determine Theoretical Minimum Number of Workstations Question: What is the theoretical minimum number of workstations for this problem? Answer:

4. Example of Line Balancing: Step 4: Rules To Follow for Loading Workstations A number of simple rules have been proposed for assigning tasks to work stations. –Assign Tasks With The Most Following Tasks First –Assign Tasks With the Longest Task Time First For this example, we’ll use –Primary: Assign tasks in order of the longest operating time –Secondary (tie-breaking): Assign tasks in order of the largest number of following tasks.
