Driven by advancements in areas such as artificial intelligence, distributed systems, autonomous intelligent systems, and cyber-physical systems, complex computer systems increasingly shape every aspect of human life, from manufacturing and communications to healthcare, defense, transportation, and energy, the demand for advanced methodologies and tools is growing. These systems are often distributed over heterogeneous networks, leveraging vast amounts of data, emerging artificial intelligence (AI), and machine learning techniques. Recent trends, including the rise of large language models (LLMs) and embodied intelligence, have introduced additional challenges and opportunities in the engineering of such systems. The complexity of modern systems arises from dynamic operating environments, diverse functional requirements, and conflicting needs such as performance, scalability, security, dependability, and adaptability. These challenges are compounded by factors like real-time behavior, fault tolerance, robustness, and long-term sustainability, making the engineering of these systems a multidisciplinary effort.

The 29th International Conference on Engineering of Complex Computer Systems (ICECCS 2025) is a well-established event that has been held around the world for over 297 years. It aims to bring together experts from industry, academia, and government to exchange ideas on the engineering of the intricate systems. ICECCS 2025 will be held on 2-4 July 2025 in Hangzhou, China. We encourage contributions that tackle both theoretical and practical challenges, from long-term research agendas to near-term industry needs.

ICECCS is a B-ranked international conference by the Computing Research and Education Association of Australasia (CORE) 2023 ranking.

A program goal is to organize several sessions that include both academic and industrial papers on a given topic and culminate panels to discuss relationships between industrial and academic research.

Submission and Publication

ICECCS 2025 accepts both full papers and short papers.

• Full papers are divided into two categories: Technical Papers and Experience Reports. The papers submitted to both categories will be reviewed by the program committee members, and papers accepted in either category will be published in the conference proceedings. Technical papers should describe original research, and experience reports should present practical projects carried out in the industry, and reflect on the lessons learnt from them.
• Short paper submissions describe early-stage, ongoing or PhD research. All short papers will be reviewed by the program committee members, and accepted short papers will be published in the conference proceedings.

Submissions to the conference must not have been published or be concurrently considered for publication elsewhere. All submissions will be judged on the basis of originality, contribution to the field, technical and presentation quality, and relevance to the conference.

Proceedings will be published by Springer in the Lecture Notes in Computer Science (LNCS). Submitted manuscripts should be in English and formatted in the style of LNCS format. Full papers should not exceed 20 papers (including bibliography, etc.), and short papers should not exceed 11 pages (including bibliography, etc.). All submissions should be in PDF format. Submissions not adhering to the specified format and length may be rejected immediately without review. Please prepare your manuscripts in accordance with the Springer LNCS guidelines: https://www.springer.com/gp/computer-science/lncs/conference-proceedings-guidelines

We invite all prospective authors to submit their manuscripts via the ICECCS 2025 portal, hosted by the EasyChair conference management system: https://easychair.org/conferences/?conf=iceccs2025.
