As a Quant Analyst, you're tasked with valuing a path-dependent option using Monte Carlo simulation—for example, an Asian option whose payoff depends on the average price of the underlying asset over a period. Describe the main steps involved in performing this simulation. Additionally, discuss the key factors and techniques you would consider in a practical application to enhance both simulation efficiency and result accuracy.

假设你是一名量化分析师，被要求使用蒙特卡洛模拟对一个路径依赖型期权（例如，一个亚式期权，其收益取决于标的资产在一段时期内的平均价格）进行估值。请你阐述进行这项模拟的主要步骤，并讨论在实际应用中，为了提高模拟效率和结果准确性，你会考虑哪些关键因素和技术？
