Seasonal Stochastic Volatility: Implications for the Pricing of Commodity Options

open access: yes, 2016
Many commodity markets contain a strong seasonal component not only at the price level, but also in volatility. In this paper, the importance of seasonal behavior in the volatility for the pricing of commodity options is analyzed. We propose a seasonally

Generalized optimization framework for synthesis of thermally coupled distillation columns

open access: yesAIChE Journal, EarlyView.
Abstract In this article, a generalized optimization framework is proposed for the synthesis of thermally coupled distillation systems within an equation‐oriented environment. The proposed framework consists of three components: an efficient superstructure representation, a novel mathematical formulation, and the associated solution algorithm ...

Asymptotic Analysis for One-Name Credit Derivatives

open access: yesAbstract and Applied Analysis, 2013
We propose approximate solutions to price defaultable zero-coupon bonds as well as the corresponding credit default swaps and bond options. We consider the intensity-based approach of a two-correlated-factor Hull-White model with stochastic volatility of

Optimal reactive operation of general topology supply chain and manufacturing networks under disruptions

open access: yesAIChE Journal, EarlyView.
Abstract Supply and manufacturing networks in the chemical industry involve diverse processing steps across different locations, rendering their operation vulnerable to disruptions from unplanned events. Optimal responses should consider factors such as product allocation, delayed shipments, and price renegotiation, among other factors. In such context,

Large deviations for fractional volatility models with non-Gaussian volatility driver [PDF]

open access: yesarXiv, 2020
We study stochastic volatility models in which the volatility process is a function of a continuous fractional stochastic process, which is an integral transform of the solution of an SDE satisfying the Yamada-Watanabe condition. We establish a small-noise large deviation principle for the log-price, and, for a special case of our setup, obtain ...

Reinforcement learning for optimal control of stochastic nonlinear systems

open access: yesAIChE Journal, EarlyView.
Abstract A reinforcement learning (RL) approach is developed in this work for nonlinear systems under stochastic uncertainty. A stochastic control Lyapunov function (SCLF) candidate is first constructed using neural networks (NNs) as an approximator to the value function, and then a control policy designed using this SCLF is developed to ensure the ...

Geometric Asian Options Pricing under the Double Heston Stochastic Volatility Model with Stochastic Interest Rate

open access: yesComplexity, 2019
This paper presents an extension of double Heston stochastic volatility model by incorporating stochastic interest rates and derives explicit solutions for the prices of the continuously monitored fixed and floating strike geometric Asian options.
