An integrated simulation model development environment was implemented to assist the modeler by automating certain activities of simulation modeling. The system included interactive model definition, experimental design, automatic simulation program generation in SLAM II. Object-oriented paradigm at software development stage was extensively used to conceptualize the structure, and rules of the SLAM II language in order to generate efficient, and modular program code. The present system targeted modeling of various probabilistic inventory control system problems. The remarkable advantages of the system were rapid model development time, and achieving reliable program code without requiring any knowledge in SLAM II. Object-oriented programming was very promising, and effective programming paradigm in system development cycle.

At the final stage, Response Surface Methodology (RSM) in conjunction with the steepest-ascent method was used to find the optimum inventory policy minimizing the average cost per unit of time based on the simulation output. Comparing the RSM results to those of the deterministic relaxation of the probabilistic inventory model demonstrated that RSM is an efficient tool for optimization in simulation.
