	Funding: Innovative Fund of IHEP The physical design and research work of China Electron Positron Collider (CEPC) is an unprecedented challenge in the field of international accelerator collider. In the simulation research, many physical phenomena must be considered, including large Piwinski angle, crab waist colliding, strong nonlinear effect, energy sawtooth, beam-beam, etc. To address this challenge, a software project APES is proposed in 2021. And this project received support from the IHEP innovative fund in 2022. The progress and future plans of APES project will be introduced in the poster.

	As a fourth-generation light source, HEPS employs a compact multi-bend achromat dispersion structure and uses a large number of combination magnets, which brings new challenges to beam parameter control. In order to meet the beam commissioning requirements of HEPS, a new high level application (HLA) development framework was designed and named Pyapas. The new framework adopts a model-based control strategy, a double-layer physical model module is designed for online calculation, which can address complex physical parameter tuning issues. To facilitate physicists in beam commissioning and research, the new framework is designed based on physical quantities,, which can be more intuitive in the commissioning process for measuring parameter analysis. And Pyapas also uses modular design to reduce development time. In March, 2023, HEPS began beam commissioning work of Linac. With the help of the HLAs based on physical quantities, we quickly found the appropriate working mode and achieved full-line beam pass-through. The report will detail the design concept and features of Pyapas.
