A. Let's say you're in charge of production at a manufacturing plant. You have a main production line that produces a product, but there are also several smaller "feeder" lines that supply materials to the main line. In order to represent these feeder lines in the rate routing, you can create parallel sequences to the main line. This means that you'll have a separate sequence for each feeder line, but they'll all be linked to the main line in the routing. For example, if your main line produces cars and you have feeder lines for the engines, tires, and seats, you can create three parallel sequences for each of those feeder lines. This way, you can track the progress of each feeder line separately and make sure they're all on schedule.
B. Sometimes, the feeder lines themselves have sub-processes that need to be tracked separately. In this case, you can create parallel sequences to a parallel sequence. This means that you'll have a sequence for each feeder line, and within each of those sequences, you'll have additional sequences for the sub-processes. Continuing with our car manufacturing example, let's say the engine feeder line has a sub-process for installing the pistons and another sub-process for installing the spark plugs. You can create two parallel sequences within the engine feeder line sequence to track these sub-processes separately.
C. When you're managing production, it can be difficult to keep track of all the different sequences and sub-processes. That's why the rate routing includes a graphic display of the sequences and operations you've created. This display makes it easier to see the relationships between the different sequences and how they fit together in the overall production process. For example, if you're looking at the graphic display for the car manufacturing process, you'll see the main line sequence with parallel sequences for the engine, tires, and seats. Within the engine sequence, you'll see the parallel sequences for installing the pistons and spark plugs. This visual representation helps you plan out the production process more effectively.
D. The rate routing includes a separate column for the takes of a line segment. This refers to the amount of time it takes for a product to move through a specific segment of the production line. By assigning operations directly to a takt, you can make sure that each operation is completed within the allotted time for that segment. For example, let's say it takes 10 minutes for a car to move through the engine installation segment of the production line. You can assign the operation of installing the pistons to a 5-minute takt and the operation of installing the spark plugs to another 5-minute takt. This way, you know that both operations will be completed within the 10-minute time frame.
E. Not all operations in a production process are equally valuable. Some operations may be necessary but don't add any value to the end product. In order to optimize the production process, it's important to identify these non-value-added operations and evaluate them in the line balance. For example, let's say that in the car manufacturing process, there's an operation that involves moving the car from one end of the production line to the other. This operation doesn't add any value to the car itself, but it's necessary in order to move the car through the different segments of the production line. By identifying this non-value-added operation, you can evaluate its impact on the overall production process and determine whether it can be optimized or eliminated to make the process more efficient.
