Chapter 1. Retailer’s Optimal Ordering Policy under Supplier Credits when Demand is Fuzzy and Cloud Fuzzy -- Chapter 2. An Application of PSO to Study joint policies of an Inventory Model with Demand Sensitive to Trade credit and Selling price while Deterioration of item being controlled using...

This paper introduces a nonlinear certainty-equivalent approximation method for dynamic stochastic problems. We first introduce a novel, stable, and efficient method for computing the decision rules in deterministic dynamic economic problems. We use the results as nonlinear and global...

How accurate is a log-linear approximation of the New Keynesian model when the nominal interest rate is bounded by zero? This paper compares the solution of the exact non-linear model to the log-linear approximation. It finds that the difference is modest. This applies even for extreme events in...

The Breslow (1974) and Efron (1977) approximations are two of the most widely-used methods for calculating the computationally-intensive partial likelihood function of continuous-time Cox (1972)-type proportional hazards regressions in the presence of tied data. This article develops analytical...
