Development and Application of Compensation Algorithm for Value Fluctuations Arising from Additional Floor Elevator Installations
Implementing elevator retrofitting projects for old residential buildings can enhance living convenience and increase overall property values.However,lower-floor residents often oppose such installations due to the potential depreciation in their property values,posing a primary obstacle to project progress.This paper developed a floor value assessment method centered on the Black-Scholes model,based on the assumption of a no-arbitrage market.By calculating the value changes of each floor after elevator installation,the proposed model aimed to determine a reasonable compensation scheme.to enable value equilibrium,the value discrepancies across floors before and after the retrofit were anlyzed,compensation or payment amounts that ensure no arbitrage opportunities for any floor residents was calculated,ensuring the consistency in floor value coefficients before and after the elevator installation.The method proposed in this paper provides a new theoretical basis for the equitable implementation of elevator retrofitting projects,effectively addressing conflicts of interest among residents on different floors.It thus facilitates the smooth progress of elevator retrofitting based on market fairness principles and offers significant practical reference value.
