“…Modules from the palette can be incorporated back into models simply by drawing the desired module from the palette and then dropping it into a model. [Ulgen and Thomasma 1986], and RESQME [Gordon et al, 1986]. These systems have shown considerable promise in terms of the ability to help deal with complexity and for provision of ease-of-use.…”

“…Like its predecessor SmartSim (Ulgen and Thomasma, 1986, 1987a, 1987b, Thomasma and Ulgen 1988, it is based on the objectoriented programming language Smalltalk, but it also provides an environment for description of new objects and new behaviors without any programming.…”

Simulation Program Generators (SPGs) developed using object-oriented environments may be designed to have a number of capabilities not available in traditional SPGs.One such capability is the description of an object's behavior from scratch without any programming when such behavior does not exist in the knowledgebase of the SPG.SmarterSim is an SPG that is currently being developed to provide the user a number of objectoriented tools including libraries of elemental operations, actions/requests, states, and rules and a number of function block templates to create new behavior using the existing primitive elements.The behavior of objects in a robotic manufacturing cell is described using SmarterSim.Like its predecessor SmartSim, SmarterSim supports a hierarchical, modular modeling for building of subsystems (coupled models) from model objects (atomic models) using subsystem management features. The paper also discusses the use of object oriented environments for traditional SPGs and simulation programming languages.

“…The same is also true if a n e w behavior is to be modeled for a currently available object. Programmer-free simulation environments based on object.-oriented languages such as Smalltalk (Knapp 1986, Ulgen and Thomasma 1986, 198?a, 198733, Thomasma and Ulgen 1987, 1988 are much easier to extend due to their class/object/message and inheritance structures but still require a programmer to incorporate t h e new behavior 01: object into the environment. This paper will describe a programmer-free, icon-based intelligent simulation environment called SmarterSim that is extensible.…”

The environment we describe in this paper has a structure analogous to the structure of the REGENT (Encarnacao and Schlechtendahl 1983) integrated system for computer aided design in mechanical engineering ( Figure 1).…”
