An (s, S) inventory system with service facilities has been investigated in this study. Demands arrive as a Poisson process with parameter λ (0) to an infinite capacity pool at any given time t. When the inventory is greater than the buffer size a customer will transfer to the buffer with rate...

We show how solutions to a large class of partial differential equations with nonlocal Riccati-type nonlinearities can be generated from the corresponding linearized equations, from arbitrary initial data. It is well known that evolutionary matrix Riccati equations can be generated by projecting...

In this paper we study an incomplete Brownian motion market and use filtration reduction to obtain a complete market, and hence a unique pricing measure. We then uplift the obtained measure to the original market and study valuation and hedging via the uplifted measure. We show how a general...

Uncertainty is becoming a constant throughout the global supply chain as reliability of suppliers and fluctuations in demand are increasingly prevalent worries for companies today. To account for this uncertainty, it is vital to implement mitigation strategies, such as purchasing and exercising...

In transportation systems with mobile and modular facilities, decisions related to facility location and facility capacity management during the planning horizon are critical; because the parameters effective in these decisions change over time, and it is necessary for the decision-maker to...

Easy to compute exact maximum likelihood estimators (MLEs) for parameters of a stochastic bivariate Itô Susceptible-Infected-Recovered (SIR) model and for parameters of an extension that treats undercounting are presented here

Despite the economic importance of PRRS and its high prevalence in Costa Rica, there are no studies on the bioeconomic impact of the disease in the country or, even, in Central America. Therefore, the objective of this study was to evaluate economic and production parameters of a PRRS-free...

The high integration of variable renewable sources in electric power systems entails a series of challenges inherent to their intrinsic variability. A critical challenge is to correctly value the water available in reservoirs in hydrothermal systems, considering the flexibility that it provides....

This paper studies inference for the realized Laplace transform (RLT) of volatility in a fixed‐span setting using bootstrap methods. Specifically, since standard wild bootstrap procedures deliver inconsistent inference, we propose a local Gaussian (LG) bootstrap, establish its first‐order...

The parametric estimation of stochastic differential equations (SDEs) has been the subject of intense studies already for several decades. The Heston model, for instance, is based on two coupled SDEs and is often used in financial mathematics for the dynamics of asset prices and their...
