Fidelity versus Cost and Its Effect on Modeling and Simulation
Abstract
In both the private sector and government organizations, pressure is continuously applied to the work force to produce "better, faster, and cheaper." "Cheaper" (i.e., the reduction of expenditures) and its effect on the end product and its users is the focus of this paper. The modeling and simulation world is not immune to rising costs and reduced budgets. Included in the applications of models and simulations are training, analysis, experimentation, and acquisition. Each of these applications can be adversely affected by poor fidelity. In some cases cost may be the culprit or may contribute to the problem. The questions one must answer are as follows: (1) Is the resultant simulation good enough to meet the customer's needs?; (2) Is the customer satisfied with the simulation?; and (3) Will the end user trust the simulation? Another area of concern is safety. The fidelity of an aircraft simulator comes to mind. If the fidelity is poor, will the pilot, air crew, and their families suffer due to poor training? Organizations may be forced to reduce fidelity to save money or meet a budget. In some cases, the trade-off is insignificant, while in other cases the result cannot be conveyed in currency. This paper explores the sacrifices that can occur in simulation fidelity due to cost restrictions, and their potential impact upon the end user.
