Digital Computer Simulation Models of Library-Based Information Retrieval Systems. Reports on File Organization Studies.
Reilly, Kevin D.
A simulation study of library-based information retrieval systems is described. Basic models for each of several important aspects are presented: (1) user behavior, emphasizing response to quality and delays in services; (2) the scheduling of services and the organization of the machine-readable files; and (3) the distribution of conventional library materials. Many of the variables in the model (e.g., user expectations of service time, delays involved in providing services, etc.) are random. An adaptive element is present in the form of admitting changes in user expectations in response to system changes. The need for frequent model change and the merging of component models into a comprehensive model for the entire system is established as the basis for use of a user-oriented simulation language. Statistical facility beyond that supplied in the language used (GPSS/360) is required to achieve the goals of this and related investigations. (Author)
