The use of computer simulation as a strategic decision-making tool: a case study of an emergency department application.

Computer simulation is a recognized decision support tool, one which has been used in many healthcare applications. Simulation offers the benefit of constructing and analyzing multiple "what if" scenarios without disrupting patient care or incurring significant cost. This article describes the successful use of computer simulation in the evaluation of multiple restructuring options in the emergency departments of a health sciences centre. Healthcare executives require timely and meaningful information to assist with strategic choices, and computer simulation can play a significant role in decision support.
