The is a new control under the bonnet of the greenhouse model computer programme SIOM . This , harmonize to Egon Janssen of TNO , allows the program to compete well with horticulturalists ' own commercial-grade controllers . The new version of the program also brings opportunities for growers , such as compare two growing strategies .
It is one of the update over the previous version . " One simulation take 15 minutes . In this new version , it is potential to simulate 20 simulation at once for one whole year . For example , think of twenty temperature fluctuation of 0.1 point Celsius each prison term . For next winter , when cultivation will be much more get-up-and-go - effective , such a simulation provides insights in overture about energy consumption and about the essence of a refinement strategy on the plant . " An under - the - hood improved craw desiccation fashion model help with this .

More datum for calibrationThe newfangled restrainer and the improved manikin under the cowling of SIOM are a grown step forwards , says Egon , the nursery facial expression of TNO to the outside . " We now have a system that permit every horticulturist to make a fair comparison between unlike technological solutions . "
Yet oeuvre is already afoot at TNO in Delft on the next step . The models within SIOM take a lot of thing into account but not yet disease and crop handling , for example . For that reasonableness , SIOM has been validated on some pragmatic greenhouses . " Now that , thanks to the Hortivation Hub and Greenhouse Performance Monitoring , it is becoming increasingly easy to retrieve bailiwick data point from a greenhouse , we can form towards validation tailored to the specific placement . "
What TNO is aiming for is that SIOM can eventually be validated with datum from greenhouse of glasshouse builders affiliated with the Hortivation Foundation . " Every greenhouse detergent builder wants to be able-bodied to do something specific , something different , with SIOM . Our goal is , therefore , to make SIOM as conciliatory as possible . "

More usersSIOM is presently still in the main used by turnkey greenhouse builder , but TNO would like to see more and more other parties using it too . Together with the Hortivation base , it was therefore decided to also make SIOM usable in an educational version for MBO and HBO further Education Department courses . That style , the raiser and nursery builders of the futurity can already apply the possibility of SIOM during their studies . " In doing so , they could , for example , forecast their strategy for a wintertime craw . "
New updatesMeanwhile , new questions keep add up up to facilitate amend SIOM . " Being able to compare different semi - closed systems is a regard , " he enunciate . A forthcoming update will provide a module that can quickly compare different scenarios . " That will total out in early 2023 , " Egon knows . " This will make it potential to fix what it has to comply with for the engineering in the greenhouse . Think of questions like : How many stage can a greenhouse heat up per hour at most ? Or vice versa : How much should the maximum yield of a heat system be ? "
One authoritative comment Egon would like to make , however . Despite all the technical innovations , it stay on a manikin . " Very uttermost strategy can be cypher , but because of the still limited circle of virtual data , the results are less reliable . It , therefore , remains necessary to keep using ordinary grower ’s common sense as well . "
