Keeping Pace with Changes - Towards Supporting Continuous Improvements and Extensive Updates in Manufacturing Automation Software

Every long-term used software system ages. Even though intangible goods like software do not degenerate in the proper sense, each software system degenerates in relation to the everlasting changes of requirements, usage scenarios and environmental conditions. Accordingly, operational software is commonly situated in a continuous evolution process in which manually conducted modifications and adaptations try to preserve or reinforce its quality. Unfortunately, such an unmanaged evolution inevitably leads to a discrepancy between the obsolete originally documented requirements and the updated software itself. For this reason, our contribution presents a coherent vision of an anti-aging cycle that preserves (non-)functional requirements as explicit runtime artefacts. The fulfilment of these requirements is validated based on conditionally triggered online test cases. In order to achieve an enhanced semantic test coverage, these test cases are adapted by monitoring, analysing and learning typical system behaviours. To explain our vision in more detail and demonstrate the benefit of a managed software evolution, our anti-aging cycle is exemplarily applied on the domain of manufacturing automation

Incremental Consistency Checking in Delta-oriented UML-Models for Automation Systems

Automation systems exist in many variants and may evolve over time in order to deal with different environment contexts or to fulfill changing customer requirements. This induces an increased complexity during design-time as well as tedious maintenance efforts. We already proposed a multi-perspective modeling approach to improve the development of such systems. It operates on different levels of abstraction by using well-known UML-models with activity, composite structure and state chart models. Each perspective was enriched with delta modeling to manage variability and evolution. As an extension, we now focus on the development of an efficient consistency checking method at several levels to ensure valid variants of the automation system. Consistency checking must be provided for each perspective in isolation, in-between the perspectives as well as after the application of a delta.Comment: In Proceedings FMSPLE 2016, arXiv:1603.0857

Open Source Software for Integrated Library System : Relative Appropriatness in the Indian Context

Libraries in all fields of human activity are involved in collection, preservation, management, and effective distribution of information that determines the quality of development in concerned sectors including that of higher education and research. Now information is flooding and along with that the recorded information to be managed; which necessitates automation of libraries to make the information stored in their collections useful and retrievable. Hitherto the cost of commercial packages for automation has prevented millions of libraries from using those tools. The recent emergence of Open Source Software has drastically reduced the cost of automation as well provided tools for new and innovative information services. The present research work focuses on comparative study of library automation packages with stress to appropriateness of Open Source Integrated Library Systems (OSILS) for countries like India. Study is based on a survey among library professionals from India using commercial and OSILS packages. The sample users belong to 601 libraries covering university, college, school, special and research libraries using any one of the integrated library systems. Packages covered is limited to the software /versions used in India. The survey found that features users of library automation packages consider are cost effectiveness, technical infrastructure, staff skills, software functionality and the availability of support, documentation and community. Study revealed that OSILS provides technological freedom and so is changing the landscape of library automation. Survey found Koha to be most popular in India. Suggests solutions to improve the situation. Few recommendations are provided to help libraries to choose suitable OSILS by understanding their advantages. Opines that being an attractive alternative to costly commercial package for any type of libraries OSILS, which is free to experiment and easy to use and customize for local requirements needs to be promoted in Indian libraries
