Working environment affects human health condition and performance. Human Factors (HF) scholars aim to elaborate this effect. However, HF studies mostly focus on employee occupational health and safety elements and their consequences on employee health conditions. They do not take into account...

recently, the Omega ratio was thought to be computationally intractable, and research was focused on heuristic optimization … procedures. We have shown elsewhere that the Omega ratio optimization is equivalent to a linear program and hence can be solved … examine the worst-case Omega ratio optimization problem under three types of uncertainty – mixture distribution, box and …

We propose a new heuristic algorithm to improve the computational efficiency of the general class of Multi-Echelon Technique for Recoverable Item Control (METRIC) problems. The objective of a METRIC-based decision problem is to systematically determine the location and quantity of spares that...

This work proposes an algorithm that makes use of partial information to improve the convergence properties of the value iteration algorithm in terms of the overall computational complexity. The algorithm iterates on a series of increasingly refined approximate models that converges to the true...

Increased competition in business environments requires that firms provide not only quality but also timely service with minimal cost. Offering a delivery-time guarantee may increase the demand for a product or service, or allow the firm to charge a price premium. This paper investigates the...

In this paper, we demonstrate how to model a discrete-time dynamic process on a non-periodic time domain with applications to operations research. We introduce a discrete-time model of inventory with deterioration on domains where time points may be unevenly spaced over a time interval. We...
