1. A method for improving drilling performance of a drilling tool assembly, the method comprising:
- identifying a drilling performance parameter to be improved;
defining at least one potential solution to improve the drilling performance parameter;
performing a drilling simulation of the at least one potential solution, wherein the drilling simulation comprises simulating an effect on the drilling tool assembly of an interaction of at least one cutting element of a drill bit with an earth formation; and
determining, based upon the drilling simulation, whether the drilling performance parameter is improved by the at least one potential solution.

Abstract
A method for improving drilling performance of a drilling tool assembly is disclosed. The method includes identifying a drilling performance parameter to be improved. One or more potential solutions are defined to improve the drilling performance parameter. A drilling simulation is performed to determine the dynamic response of the drilling tool assembly during a drilling operation. Determining the dynamic response includes determining the interaction of a cutting element of a drill bit with an earth formation. Improvement in the drilling performance parameter is determined based upon the drilling simulation.
