Abstract

Simulation is an established technique that provides a rapid and effective means of provides a rapid and effective means of evaluating existing or proposed system operations. It has proved effective in assisting managers and designers to make decisions at significant cost reductions below real-life testing. This paper explores the research and problem definition aspects of simulation. It describes a new on-line simulation technique and emphasizes the merits of an interactive approach to modeling. This approach helps the user control, from a terminal, some decisions before all data are available and all alternative decision logic has been defined.

This approach is compared to standard simulation techniques throughout each step of development study. Examples are given from pipelines, fuel supply, and power supply systems, including tankers, barges, storage tanks, and power plants.

Introduction

In practice, it is management responsibility to make things work. Good management will make its decision on the basis of performance data and anticipated problems. performance data and anticipated problems. or react to difficulties as they are encountered. Management control is not necessarily automatic, and, therefore, its logic is not always easily programmed.

Essentially, management interacts with operations, according to planned decisions, and counteracts adverse conditions as they arise. Simulation is a tool that allows the manager to anticipate operational difficulties and pretest the consequences of his decisions on existing or proposed systems at significant cost reductions below real-life testing.
