With the motto of “doing it right first time”, this study focuses on spearheading integration designers, constructors, and facility mangers, at outset planning/design stage, by providing easy-to-read tables summarising (1) knowledge learnt from past mistakes (2) maintainability benchmarks, to ensure high for Basements Wet Areas. The commonly occurring problems in Areas a total 110 buildings com...

With the arrival of large real-time, time-shared systems, the requirement of system reliability has become even more demanding. The result of even a momentary system misbehavior could be catastrophic, since any disruption of service is experienced by all the users on-line at that time. Thus for real-time systems such as telephone switching systems, airline reservation systems, on-line teaching ...

We have examined 365 versions of Linux. For every version, we counted the number of instances of common (global) coupling between each of the 17 kernel modules and all the other modules in that version of Linux. We found that the number of instances of common coupling grows exponentially with version number. This result is significant at the 99.99% level, and no additional variables are needed ...

The recording and management of design rationales and design decisions are important issues in achieving better support for software maintenance. In the c ontext of existing work on design rationale models, this paper intr oduc es an appr oach to the integration of system design, design decisions and design rationales and the formalisation of design decisions in terms of software artifacts and ...

The complexity involved in operationalizing the method for nursing staffing, in view of the uncountable variable related to identifying the workload, the effective working time of the staff, and the Technical Security Index (TSI) revealed the need to develop a software program named: Computerized Nursing Staffing (DIPE, in Portuguese acronyms). This exploratory, descriptive study was performed ...
