3 - Efficient Multi-fidelity Decision Making For Dynamic Data Driven
Application Systems
Jie Xu, George Mason University,
jxu13@gmu.eduChun-Hung Chen, Edward Huang
Dynamic data driven application systems enable real-time simulation-based
decision making. However, existing simulation optimization algorithms lack the
computational efficiency required for real-time decision making. In this talk, we
present a Bayesian framework that makes use of data and models of multiple
fidelity levels to achieve the computational efficiency necessary for decision
support in the context of dynamic data driven application systems.

We present a dynamic data-driven modeling strategy, capable of tracking and
predicting the transient dynamics of nanoparticle production processes. The
proposed methodology is built upon two emerging multi-resolution instruments.
The methodology regularly triggers cheap low resolution measurements while
triggering expensive high resolution measurements when model predictions fail.
The proposed strategy would provide crucial clues to understand nanoparticle
productions as well as powerful insights to control the production of
nanoparticles for yielding desirable morphology.

Onshelf Deterioration
Haitao Liao, University of Arkansas,
liao@uark.eduWe study maintenance and inventory policies for a system carrying spare parts
that experience two-phase on-shelf deterioration. Based on the parts’ degradation
states, we introduce two different replacement strategies for the spare
consumption, i.e., the Degraded-First strategy and the New-First strategy.

Maintenance

In this paper, we explore the impact of Kijima Type II imperfect repair model on
equipment availability. Our specific interest is in the system steady-state
availability. Since the derivation of a closed form expression for the limiting
availability is extremely difficult, we use simulation modeling and analysis to
estimate the system limiting availability. Next, we develop a meta-model to
convert the system reliability and maintainability parameters into the coefficients
of the limiting availability estimate without the simulation effort. Lastly, we
identify an optimal age-based preventive maintenance policy that maximizes the
system’s steady-state availability.
3 - Predictive Maintenance For A Multi-unit System
Yisha Xiang, Lamar University,
yxiang@lamar.eduZhicheng Zhu, David W Coit
Preventive maintenance has been extensively studied. Time-based PM and
condition-based maintenance (CBM) are two major approaches for PM. However,
time-based PM is often associated with high occurrence of system breakdowns,
and CBM might incur more-than-necessary inspections. Recently, predictive
maintenance has become popular since it aims to pinpoint when a failure is about
to occur and prolong the operational time. However, only a few predictive models
consider a multi-unit system. In this paper, we develop an opportunistic
predictive maintenance structure for a multi-unit system. Numerical examples are
provided to illustrate the proposed predictive maintenance policy.
4 - Reliability Of System With Clusters Of Dependent
Degrading Components

A reliability model is developed for complex multi-component system with each
component subject to multiple failure processes. Degradation paths for certain
components are stochastically dependent with clusters of dependent components.
Gamma process is used to model the stochastic process of component
deterioration. In this new model, two failure processes within each component
are dependent due to simultaneous shared exposure to shock process.
Furthermore, degradation paths among certain components are considered to be
dependent. Components sharing dependent degradation can be determined by
the MLE of model parameters.

This paper estimates econometric models of empty trips of different commodities
and vehicle types. In doing this, panel models with time-dependent parameters
and fixed effects are used to assess how parameters change over time considering
different commodities, and to detect the presence of time effects not captured by
the other parameters. The performing of the formulation for the different
commodities is tested in Colombia.

pazouj@rpi.eduOn-demand peer-to-peer logistics systems use a business model for the movement
and storage of goods that matches independent supply resources (warehouse
space, truck space, delivery services) to demand requests on demand. These
systems are part of the growing sharing economy and gig economy. We identify
the unique features of these systems, comparing and contrasting them with
traditional logistics systems. By mapping the characteristics to supply chain
principles, we identify challenges with designing and operating, as well as using
