3 - Efficient Multi-fidelity Decision Making For Dynamic Data Driven

Application Systems

Jie Xu, George Mason University,

jxu13@gmu.edu

Chun-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.

4 - Dynamic Data Driven Modeling Of Nanoparticle

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.

1 - Reordering Of Spare Parts Experiencing Two Phase

Onshelf Deterioration

Haitao Liao, University of Arkansas,

liao@uark.edu

We 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.

2 - A Model Of System Limiting Availability Under Imperfect

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,

Zhicheng 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.

1 - On The Unique Features Of On-demand Peer-to-Peer

Logistics Systems

On-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
