Queueing theory in manufacturing: A survey

TL;DR: The survey classifies the contributions into two groups: descriptive (performance analysis) and generative (design, planning, and control) and software based on analytical models in queueing theory, as applied to manufacturing.

Design of manufacturing systems using queueing models

TL;DR: It is shown how the structural properties that are recently derived for single and multiple stage queueing systems can be used effectively in the solution of certain design optimization problems.

Parametric stochastic convexity and concavity of stochastic processes

TL;DR: In this article, a notion of directional convexity (concavity) is introduced and its stochastic analog is studied, and a sufficient condition on the transition matrix of a discrete time Markov process is found.

Regularity of Stochastic Processes: A Theory Based on Directional Convexity

TL;DR: In this paper, the authors define a notion of regularity ordering among stochastic processes called directionally convex (dcx) ordering and give examples of doubly-stochastic Poisson and Markov renewal processes where such ordering is prevalent.

Rearrangement, majorization and stochastic scheduling

TL;DR: Stochastic versions of Day's Inequality are developed, over both unrestricted and restricted permutations, which are applied to solve the stochastic version of several classical deterministic scheduling problems.

Shock Models and Wear Processes

TL;DR: In this article, the life distribution of a device subject to shocks governed by a Poisson process is considered as a function of the probabilities of not surviving the first $k$ shocks.
