Describes computer program which converts text of user input and system responses from online search system into fixed format records describing interaction. Query language syntax, format of output record produced by parser, problems in constructing parser, its performance characteristics, and recommendations for improving process of logging…

The main purpose of the research reported in this document was to discover whether controlled experiments can be conducted on the relations between people and the complex computing systems which they use. Three increasingly complex experiments were designed to test the effect of varying delays of computer response on the number of commands issues…

Four computer programs to aid students in understanding inventory systems, constructing mathematical inventory models, and developing optimal decision rules are presented. The program series allows a user to set input levels, simulates the behavior of major variables in inventory systems, and provides performance measures as output. Inventory…
