When you run the cut optimization, apart from the cutting scheme you also get the statistics. Cut list cost is probably the most important. It tells how much money you need to finish the project. You can make competitive price to the client knowing this. Other important statistic is the actual number of bars you need to do the work. Following is the quick explanation about all statistics. There are two types of stats — overall and per bar.
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. 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 quite lower the 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 20 bars of length 6000 and you have them in stock and 20 bars of length 4000 but you only have 4 and need to order 16. 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. Check the following images to see how they may look like:
- Available – 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 yellow.
- Side&Cut – Total cut and side waste for the particular bar.
- Useful – Sum of the lengths that were cut from the particular bar.
