  • Publication number: 20250190646
    Abstract: Right decisions can only be made via understanding future trends. For example, energy consumption prediction is the basis of all Energy Management Systems (EMS). Any EMS decision-making must rely on the energy consumption prediction value for subsequent power grid planning or factory management. These prediction values play decisive roles in planning and management. A virtual metrology method based on a long sequence time-series prediction framework develops the Automatic Virtual Metrology (AVM) which can provide accurate predictive future trends to increase decision-making accuracy (such as production scheduling or facility control). The built-in period calculator module is used to automatically find out a best memorizing length, a best forecasting length and a best full-periodic pattern length for the long sequence time-series prediction framework.

  • Publication number: 20240095755
    Abstract: A hybrid method for green intelligent manufacturing (GiM) combines the carbon reduction and the energy saving into the intelligent manufacturing based Industry 4.1 cloud platform. GiM assists companies to achieve the goal of net zero transition and help them advance to Industry 4.2 as soon as possible by simultaneously taking carbon footprint and energy issues into account. GiM collects large volumes of essential data (including carbon footprint) via cyber physical agents (CPAs), and sends them to two critical services of carbon management and intelligent energy management system (iEMS) deployed on the cloud platform. The two critical services optimize the energy dispatch schedule by strictly following the requirements of energy saving, carbon reduction, and net zero. Then, the state of zero defects of intelligent manufacturing achieved in Industry 4.1 can be upgraded to net zero of GiM in Industry 4.2.

  • Patent number: 11745267
    Abstract: An additive manufacturing (AM) method is provided. The method includes performing a laser powder bed fusion (L-PBF) process on the powder layer. Then, a first surface roughness value of the powder layer after the L-PBF process is obtained to generate a first surface profile. An absorptivity and a set of re-melting process parameters data are used to perform a heat transfer simulation. A second surface profile of the powder layer after laser re-melting is obtained by using the first surface profile and a low-pass filter. Then, the set of re-melting process parameters data is adjusted iteratively to perform the heat transfer simulation until a second surface roughness value predicted from the second surface profile is smaller than or equal to a surface roughness threshold, thereby obtaining optimal values of re-melting process parameters for performing a re-melting process to reduce a surface roughness of a powder layer after the L-PBF process.
