In recent years simulation proved to be a useful technology to support the making of recurring decisions. This paper describes the integrated simulator concept and requirements to make simulation useful for those decisions. First, the differences between onetime decisions and recurring decisions are pointed out. An important difference is that recurring decision-makers don't have assistance from simulation experts to make decisions. Therefore, decision-makers need a solution to be able to use simulation easily. Second, the integrated simulator concept is introduced. This concept can bring simulation to the desk of recurring decision-makers. This has consequences for users, simulation experts and simulation software. Finally, two cases are presented in which the integrated simulator concept proved to be successful.
