1 INTRODUCTION
The subject of this paper is the use of Discrete-Event Simulation (DES) as a decision making tool in the planning and design of hospital buildings. The basis of the paper is a review of the literature on the major issues of the US health care system and the role that building projects can play in enabling organizational change. A review of current hospital planning and design and use of DES provides the basis for describing an improved process for design of health services and facilities using DES.
