Motivated by high ecological and economical potentials, remanufacturing is receiving increasing attention as a process that puts used products into an "as-good-as-new-or-better" condition. Here, many challenges occur, which are unseen in manufacturing, resulting from unknown conditions of used products. One example is the stochastic routing of the products through the remanufacturing system (RS), which makes a flexible material transport by e.g. automated guided vehicles (AGVs) necessary. this places special demands on the control of the RS. To handle these uncertainties a decentralized-hierarchical control architecture is presented. the scheduling of machines and AGVs is optimized simultaneously using Constraint programming (CP). All the participants within the RS will be networked as a cyber-physical system and controlled by decentralized components. the approach is validated through simulation and the implementation in a model factory. Results show a 35.6% makespan reduction, short computing times and the ability to react adequately to unforeseen events.

programming assignments are crucial in programming courses designed to improve students’ practical programming skills. Assessment of these assignments are vital for instructors to evaluate student progress and provide valuable feedback. While manual assessment is effective, it is tedious and time-consuming, leading to an increased demand for Automated Assessment Tools. Integrating automated code assessment tools in programming courses stands out as a transformative approach, significantly enhancing the efficiency and effectiveness of the assessment process. through a meticulous evaluation, this study explores the leading open-source automated code assessment tools, their assessment methods, and feedback mechanisms. Moreover, this paper briefly discusses the important strengths and limitations of these tools.

Aiming at the problems of machining redundancy and rough process intersection caused by the existing single-process machining CNC programming method, a CNC programming technology based on process fusion is proposed after analyzing the polygon clipping algorithm for machining path optimization. Firstly, the geometric characteristics of the process are analyzed, and the actual machining problem is transformed into a polygon clipping problem, thus establishing a mathematical model to solve it. Secondly, a new data structure and polygon clipping algorithm are designed to speed up problem solving. Finally, the process sequence is fused to generate a more efficient and reliable process execution flow. through simulation experiments, the CNC programming technology based on process fusion is compared withthe traditional CNC programming technology, and has significant advantages in improving machining efficiency and quality.

Purpose: there is a lack of suitable recommendation systems to assist engineering teaching. the existing traditional engineering pedagogies lack learning interests for postgraduate students. the knowledge graph-based recommender system aims to enhance postgraduate students’ programming skills, with a focus on programming courses. Design/methodology/approach: the case study will be used as a major research method, and the two case studies will be taken in both two teaching styles of the universities (Zhejiang University and the University of Nottingham Ningbo China), followed by the interviews. Quantitative and qualitative research methods will be combined in this study. Research limitations/implications: the case studies were only focused on two teaching styles universities, which is not comprehensive enough. the subject was limited to postgraduate students. Originality/value: the study collected and analyzed the data from two teaching styles of universities’ perspectives. It explored the challenges of Engineering education and tried to seek potential enhancement.

In this paper, we are going to consider a current challenge in a robotic software system. We consider a problem, which is the lack of separation of concerns in robotic systems, and propose a software model to address the problem and resolve the current challenges. the core purpose of this paper is to demonstrate the advantages of using separation of concerns principles to create a well-ordered model of independent components that address separated concerns individually. Considering the problem, we developed a software model withthe help of a proactive engine to address the challenges. We use robotic operating systems to help us to implement the robot simulator.
