    A detailed survey on the motivations, design, applications, current status, and limitations of computers designed for symbolic processing is provided. Symbolic processing computations are performed at the word, relation, or meaning levels, and the knowledge used in symbolic applications may be fuzzy, uncertain, indeterminate, and ill represented. Various techniques for knowledge representation and... View full abstract»

    Hardware and software maintenance are contrasted. The key difference between the two-the ease with which software can be changed-leads to the need for managing software change. Standardization of software maintenance is proposed as a method for managing software change. A model of software maintenance is advanced as the foundation for standardizing software maintenance View full abstract»

    Starts with a brief review of the history and the application areas considered in the literature. The author then proceeds with introductory modeling examples, behavioral and structural properties, three methods of analysis, subclasses of Petri nets and their analysis. In particular, one section is devoted to marked graphs, the concurrent system model most amenable to analysis. Introductory discus... View full abstract»

    A practical approach to improving software maintenance through measurement is presented. This approach is based on general models for measurement and improvement. Both models, their integration, and practical guidelines for transferring them into industrial maintenance settings are presented. Several examples of applications of the approach to real-world maintenance environments are discussed View full abstract»

    Although it is common to view software maintenance as an activity that is distinct from software development, it is often true that the development it is often true that the development of novel products is mixed in with the evolution of existing products. Examples are families of similar applications, such as communications processors, that share considerable functionality, and a large scale info... View full abstract»
