The following description is adapted from that provided in [1]:

Sisyphus is a decision-support model for lift configuration, based on the Sisyphus-2 problem identified in [2]. The script for the ISM consists of several hundred definitions that record the elevator users requirements, the dependencies between the characteristics of different engineering components, and the observables associated with monitoring whether constraints are violated. Each of the fixes for constraint violation - documented in [3] - can be interpreted as an automatic agent. The user is presented with a menu indicating precisely which fixes are currently commended for possible execution. This creates an environment in which the modeller has discretion over which fixes are triggered, and so can explore the space of possible solutions that is accessed by such fixes in an experimental fashion. This is one of several ways in which the elevator design ISM can be used so as to combine automatic processing with human interaction. This interaction technique does not of course preclude the possibility of fully automatic execution.
