The purpose of this paper is to explain the Black–Scholes model with minimal technical requirements and to illustrate its impact from a business perspective.,The paper employs simple accounting concepts and an argument part based on business need.,The Black–Scholes partial differential equation can be derived in many ways, some easy to understand, some hard, some useful and others not. The two methods in this paper are extremely insightful.,The paper takes a big-picture view of derivatives valuation. As such, it is a simple accompaniment to more complex methods and aims to keep modelling grounded in reality.

推导Black-Scholes PDE的两种最佳方法

本文的目的是解释技术要求最低的Black-Scholes模型，并从业务角度说明其影响。​​本文采用简单的会计概念，并根据业务需求提出了论点。Black-Scholes偏微分方程可以通过多种方式导出，有些易于理解，有些难理解，有些有用，有些则无法。本文中的两种方法都极富洞察力。因此，它是对更复杂方法的简单伴随，旨在使建模保持现实。
