This project aims to develop a data-driven approach to improving the resilience of online service systems. Many software systems are now provided as online services via the Internet on a 24/7 basis. Although a lot of effort has been devoted to service quality assurance, in reality, online service systems still encounter many incidents and fail to satisfy user requests. This project expects to develop innovative data-driven methods for effective fault identification, fault localization, and failure prediction. Expected outcomes of this project include novel techniques and tools for maintaining online service systems. This project will provide significant benefits, such as improving the resilience and reliability of our cyber infrastructure.Read moreRead less

Enterprise IT systems are highly interconnected and interdependent — a failure in one system can cause a cascade of failures across multiple systems, bringing business to a standstill. The project aims to create new technologies to automate the provisioning of virtual deployment environments to test the enterprise systems. In particular, it aims to develop new methods for the automatic analysis of service interaction traces and the generation of accurate executable service models, without requiring explicit knowledge of them. The automatic analysis and generation should reduce development cost for enterprise IT systems and increase system quality and reliability. The new software deployment technologies from this project aim to significantly reduce the time, effort and cost of system quality assurance activities in software development organisations, and yet produce higher-quality software leading to uninterrupted business operation in end-user organisations across all sectors.Read moreRead less

Design-Driven Requirements for Internet-Enabled System Development. The nature of Web system development is significantly different from conventional, software and IT development. Amongst other factors, there is substantial uncertainty in both clients' understanding of their needs and developers' understanding of the systems domain. We will develop an uncertainty model relevant to the development model relevant to the development of internet-enabled systems, and then use this model to adapt th ....Design-Driven Requirements for Internet-Enabled System Development. The nature of Web system development is significantly different from conventional, software and IT development. Amongst other factors, there is substantial uncertainty in both clients' understanding of their needs and developers' understanding of the systems domain. We will develop an uncertainty model relevant to the development model relevant to the development of internet-enabled systems, and then use this model to adapt the design process to support elicitation of requirements, as well as developing support for this adapted process. This will facilitate the development of systems that more accurately reflect clients' needs, and result in an understanding of what would be involved in reducing development costs.Read moreRead less

Building correct-by-construction distributed systems from specifications stating how agents' knowledge evolves over time. Many distributed computer system implementations fail to comply with their original informal requirement specification. These requirements typically refer to the migration of information through the system over time, but current specification languages are not rich enough to express such requirements on a sufficiently abstract level. This results in a huge error-provoking gap ....Building correct-by-construction distributed systems from specifications stating how agents' knowledge evolves over time. Many distributed computer system implementations fail to comply with their original informal requirement specification. These requirements typically refer to the migration of information through the system over time, but current specification languages are not rich enough to express such requirements on a sufficiently abstract level. This results in a huge error-provoking gap between the informal requirements and the starting point of formally verifiable development. To minimise this gap, we develop a particularly expressive specification language, a calculus for stepwise refinement from such specifications down to distributed systems, and an automated tool for checking and supporting refinement steps in the calculus.Read moreRead less
