Many companies have written into their purchase orders for optimizers that the equipment must pass an acceptance test in which the actual sawing solutions are to be compared to the optimized solutions determined by SAWSIM®.
An additional benefit realized from this analysis is that, in the course of setting up the SAWSIM® model used in the test, a detailed review of the optimizer’s parameters is made. In virtually every case we have found an error in the parameters, or a possible improvement. The improvement resulting from the parameter correction or improvement pays for the cost of the acceptance test study, many times over.
The SAWSIM® Acceptance testing method has a clear advantage over other acceptance testing methods, such as before-and-after recovery of mill tests or actual mill production. The procedure is fair to both the purchaser and the vendor. It is testing that the equipment is performing in accordance with the specifications. Because the same logs are considered for both parts of the simulation, a valid apples-to-apples comparison in ensured. Of course this is not possible in real production as no two logs are the same, much less two log samples or the logs sawn in two production timeframes.
