Priority Ranking System Even in a small problem like ours, which contains only 10 tasks, there are many potential groupings of tasks into work stations. Starting from the left side of the sequencing diagram, we can identify several groupings of tasks for the first station where the tasks are in sequence and add up to 12 minutes or less. 3 Assembly Line Balancing Tasks F and G could be combined for a total of 11 minutes, A and F for a total of 10 minutes, A, B, and G for a total of 11 minutes, or A, B, C, and E, for a total of 12 minutes.
Some materials are much heavier or bulkier than others. Determining the cost of labor and equipment to transport a load one foot may not be too easy to do, but some relative estimates may be made at least. The final part of the transportation cost function is the distance between departments. This, however, is our decision variable. These distances will be determined by how we arrange the departments. After we determine a general arrangement of departments, we will need to provide a much more specific layout, including the arrangement of machines within departments.
There are several heuristic (rule-of-thumb) techniques that have been used to arrive at a good, though not necessarily optimal, solution. We will apply one such technique called the priority ranking system. In this system each task is assigned a priority. The priority is calculated by adding the time of that task with the times of all tasks that follow (through all arrows) that task. This sum will tell us the total amount of work depending on that task. This figure then gives us a pretty good measure of how desirable it is to perform that task early in order to permit all of the following work to be performed.
