Electric P8

EPLAN Electric P8 is an electrical engineering design software program that offers unlimited possibilities for project planning, documentation, and management of automation projects. The automatic production of detailed reports based on wiring diagrams is an integral part of a comprehensive documentation system and provides subsequent phases of the project, such as production, assembly, commissioning and service with the data required. Engineering data from other project areas, such as fluid and pneumatic engineering, can be exchanged via interfaces within our CAE software. This therefore guarantees consistency and integration throughout the entire product development process.

IronCAD

Design better, faster IronCAD is an intuitive 3D and 2D design solution that empowers engineers, increases productivity, and facilitates collaboration throughout the enterprise. IRONCAD 3D modeling software empowers designers to focus on design by giving them an intuitive platform that mirrors how we interact with the physical world. Easily reposition components with the patented TriBall™ visualization tool, resize objects by stretching them with handles, and drag and drop predefined shapes into the design scene for a better, faster design process. 3D models made in IRONCAD only require one file, no matter how complex. Assembly part data is integrated into a file’s unified design environment, rather than linking to external files. Feature, part, and assembly data can be stored in catalogs which can be pre-built to include frequently used parts and assemblies, freeing designers to be more productive and allowing them to extend the use of 3D data throughout the enterprise.

FlexSim

FlexSim è un software di modellazione di simulazione 3D, trasformando i tuoi dati esistenti in previsioni accurate. I nostri clienti sono ingegneri e decisori che vedono il potenziale in un processo che potrebbe essere migliorato. Il nostro approccio va ben oltre i fogli di calcolo. Combina una potente analisi statistica con la visualizzazione 3D, permettendoti di testare scenari "what if" in un ambiente virtuale privo di rischi. I nostri clienti lo usano per prendere decisioni più intelligenti dove conta davvero: nel mondo reale. Per comprendere veramente il tuo sistema di produzione, logistico o sanitario, devi tenere conto delle centinaia o migliaia di azioni complesse e interconnesse che si verificano ogni giorno. Aggiungi il comportamento casuale che si verifica sempre nel mondo reale, e hai uno scenario che non può essere considerato accuratamente attraverso i metodi di analisi tradizionali. Costruendo e valutando un gemello digitale del tuo processo, la simulazione fornisce ESATTAMENTE questo livello di accuratezza e risultati. Scopri la vera causa di un collo di bottiglia nella produzione. Trova le giuste modifiche per potenziare la velocità di prelievo degli ordini. Se puoi identificare un'area di miglioramento, la simulazione con FlexSim può aiutarti a risolvere il problema.
