When running the cutting optimization, apart from the cutting scheme you also get the statistics. Overall cost is probably the most important because it tells how much money is needed for this cutting list. Knowing this parameter it, making a price quote for the customer is much easier. Other important parameter is the number of bars you need to order to do the work. Following is the quick explanation about all statistics. We’ll start with the overall stats:
Overall statistics may look something like this:
Here is the explanation for each of these:
- Utilization – Utilization with reusable lengths not considered as waste. The purpose of cut optimization is to bring this parameter as closer to 100% as possible. Usually, it is above 90% but basically depends on the items to cut and input bar length. There are scenarios when it is not possible to have a good utilization.
- (Utilization) With reusable included – Utilization with reusable lengths considered as waste. In some situations this may be lower than the previous utilization. This optimization represents the most pessimistic scenario which can help you set the price for your customers.
- Waste – Total waste with reusable lengths not considered as waste.
- (Waste) With reusable included – Total waste with reusable lengths considered as waste.
- Counts – Number of input items in comparison to the number of items that optimization algorithm returned. These values must be the same. This is for control purposes to validate the results. Normally is marked in green, and in case the values are different this statistic is marked in red. If this happens, results are not valid and you should not go with cutting. Report this situation to our support including your account and project name.
- Total bars – Total number of bars you need (order) to do the cutting.
- Bars per length – This option is available only when more than one input length. Bar length is followed by bar quantity, separated by slash (/). In case there are not enough bars in stock you get information about how many more you need to order. In the above example, you need 13 bars of length 214 but you only have 11 and need to order 2. This option is available only in Cut Optimizer PLATINUM and GOLD plans.
- Total items length – Sum of all items length.
- Price for N bars – Cut list cost. This is how much you will pay for the bars.
- Price (reusable excluded) – Your cut list cost when reusable items are excluded from the total cost, because they may be potentially used for some other project.
Bar statistics appear on the right side of each bar after the cutting list has been generated:
- Leftover – Length of the leftover piece after cutting the bar. Marked in green if its length is longer than the minimal reusable length specified in configuration. Otherwise marked in grey color.
- Waste – Total cut and side waste for the particular bar.
- Used – Sum of the lengths that were cut from the particular bar.
