Automated synthesis of steady-state continuous processes using reinforcement learning

Frontiers of Chemical Science and Engineering 2022, Volume 16, Issue 2,   Pages 288-302 doi: 10.1007/s11705-021-2055-9

Abstract: Automated flowsheet synthesis is an important field in computer-aided process engineering.The present work demonstrates how reinforcement learning can be used for automated flowsheet synthesisThe environment consists of a steady-state flowsheet simulator that contains all physical knowledge.Therein, flowsheet synthesis is modelled as a game of two competing players.

An Intelligent Expert System on Rough Sets

Zeng Huanglin

Strategic Study of CAE 2001, Volume 3, Issue 2,   Pages 47-51

Abstract:

The basic topology, knowledge representation and inductive learning of an intelligent expert system on rough sets are introduced in this paper. Based on the indiscernibility relation of system knowledge expression, a compatible algorithm is proposed to simplify the knowledge expressions and to induce the system decision rules. In order to extract the significant attributes from elementary knowledge and to reduce the dimensions of the system representation, inductive learning is also introduced by means of reasoning the dependency of knowledge between the teacher and the learner.

Frontiers of Information Technology & Electronic Engineering 2023, Volume 24, Issue 4,   Pages 536-552 doi: 10.1631/FITEE.2200353

Abstract: In many robot operation scenarios, the end-effector’s of movement are indispensable for the task process, such as robotic welding, spraying, handling, and stacking. Meanwhile, the inverse kinematics, collision detection, and space search are involved in the procedure under , making it difficult to achieve satisfactory efficiency and effectiveness in practice. To address these problems, we propose a distributed variable density method with (DVDP-AC) for . First, a position– reconstruction (PACR) approach is proposed in the inverse kinematic solution. Then, the (DSDF) model with single-step safety sphere (SSS) is designed to improve the efficiency of collision detection. Based on this, the variable density path search method is adopted in the Cartesian space. Furthermore, a novel forward sequential (FSPS) approach is proposed to adaptively eliminate redundant path points considering path accessibility. Finally, experimental results verify the performance and effectiveness of the proposed DVDP-AC method under end-effector’s , and its characteristics and advantages are demonstrated by comparison with current mainstream methods.
