Abstract

DELAB is a simulation laboratory designed to provide support to programmers who build complex simulation programs and to system analysts who use these programs. In this paper we present the structure of the laboratory and report on the current status of the effort to implement it. The laboratory has been implemented in a 'bottom up' fashion. First we have developed the DENET simulation language which is a Modula-2 based discrete event simulation language. Once the language became operational, a database management system was added to the laboratory. For each simulation study a relational database is automatically created. When a simulation terminates it stores a description of the run in the database. The system analyst can later retrieve this data by means of a relational query language. DENET has been successfully used in a number of real life simulation studies. The database management system is currently evaluated by a number of researchers in our department who employ it in their simulation studies. The requests, criticism, and encouragement provided by users of both the language and the management system have guided our iterative effort to design and implement an effective simulation laboratory.
