造材是决定木材用途关键的一道工序。如何提高木材的出材率,减少废材,这对国民经济具有重要的意义。然而,在生产中由于不合理的造材所引起的浪费是一个不小的数字。虽然废材本身也可有某种用途,但它需要增加一定的劳动消耗;或者大大地降低它的使用价值。因此,如何减少废材是非常重要而迫切需要解决的问题。下边我们也想试用数学的方法来谈合理造材的问 Material is the key to determining the use of wood processes. How to improve the timber output rate and reduce the waste, which is of great significance to the national economy. However, the waste caused by unreasonable materials in production is not a small figure. Although the waste itself may have some use, but it needs to increase some labor consumption; or greatly reduce its value. Therefore, how to reduce waste is a very important issue that needs urgent solution. Below we also want to try the mathematical method to talk about reasonable materials
