Abstract
A computer-implemented method for controlling sawing of logs, including obtaining information of a timber lot configured to be produced from logs configured to be sawn, obtaining an optimization objective for a statistical optimization model configured to be used for producing the timber lot, and determining a sawing configuration including at least one sawing pattern for a saw, which sawing configuration is determined based on the optimization objective, which at least one sawing pattern is configured to be used for sawing the logs to timber of the timber lot. The disclosure further relates to a sawing controlling system and a computer program product performing the method.
Claims15
A computer-implemented method for controlling sawing of logs, comprising:
- obtaining a timber lot order configured to be produced from logs configured to be sawn;
- obtaining an optimization objective for a statistical optimization model configured to be used for producing the timber lot, which optimization objective is a combination of two or more of the following max quality, min production capacity, max material use efficiency, min costs, or max line speed so that the timber lot can be produced as desired;
- and
- determining a sawing configuration for the timber lot, which sawing configuration comprises sawing patterns for a saw, and which sawing configuration is determined based on at least the optimization objective, logs, and sawing properties of said sawing patterns, and which sawing patterns are configured to be used for sawing the logs to timber according to the timber lot order and the optimization objective.
A sawing controlling system comprising a saw and a process automation system comprising a data processing unit and timber monitoring means, wherein a sawing configuration comprising sawing patterns configured to be used for sawing logs configured to be sawn is determined based on timber of a timber lot order configured to be produced, an optimization objective determined for a statistical optimization model by at least the data processing unit, logs, and sawing properties of said sawing patterns, which optimization objective is a combination of two or more of the following max quality, min production capacity, max material use efficiency, min costs, or max line speed so that the timber lot can be produced as desired.
