Smart Supply Chain Management In Industry 4.0, Guoqing Zhang, Yiqin Yang, Guoqing Yang

Industrial and Manufacturing Systems Engineering Publications

The emerging information and communication technologies (ICT) related to Industry 4.0 play a critical role to enhance supply chain performance. Employing the smart technologies has led to so-called smart supply chains. Understanding how Industry 4.0 and related ICT affect smart supply chains and how smart supply chains evolve with the support of the advanced technologies are vital to practical and academic communities. Existing review works on smart supply chains with ICT mainly rely on the academic literature alone. This paper presents an integrated approach to explore the effects of Industry 4.0 and related ICT on smart supply chains, by combining …

Performance Evaluation Of Reverse Logistics Enterprise – An Agent-Based Simulation Approach, Gowtham Ravi Sankara Pandian, Walid Abdul-Kader

Industrial and Manufacturing Systems Engineering Publications

Reverse logistics (RL) has been applied in many industries and sectors since its conception. Unlike forward logistics, retracing consumer goods from the point of consumption to the point of inception is not a well-studied process. It involves many uncertainties such as time, quality and quantity of returns. The returned products can be remanufactured, have parts harvested, or be disposed safely. It is important to implement these activities in a cost-effective manner. The aim of this research is to measure the performance of the RL enterprise with the help of an agent-based simulation model. The major entities in the RL network …

Three-Dimensional Container Loading: A Simulated Annealing Approach, Hanan Mostaghimi Ghomi, Bryan Gary St. Amour, Walid Abdul-Kader

Industrial and Manufacturing Systems Engineering Publications

High utilization of cargo volume is an essential factor in the success of modern enterprises in the market. Although mathematical models have been presented for container loading problems in the literature, there is still a lack of studies that consider practical constraints. In this paper, a Mixed Integer Linear Programming is developed for the problem of packing a subset of rectangular boxes inside a container such that the total value of the packed boxes is maximized while some realistic constraints, such as vertical stability, are considered. The packing is orthogonal, and the boxes can be freely rotated into any of …

Optimal Disposition Decisions For A Remanufacturing System Considering Time Value Of Products, Mostafa Pazoki, Walid Abdul-Kader

Industrial and Manufacturing Systems Engineering Publications

This paper studies disposition decisions of cores where the value of returns deteriorates over time. Mainly in disposition decisions, a remanufacturer is interested to determine how many units to remanufacture and to salvage. To address this research problem along with value deterioration of returns, a rough-cut mathematical model is developed by considering various parameters of interest such as selling price, salvage value and remanufacturing rate with the aim to maximize total profit. Due to uncertainty limitations, the model can provide decision-makers with relevant insights about disposition decisions. Simulation modeling techniques are used to validate the proposed model. Numerical examples are …

Analysis, Modeling And Imporvement Of Stamped Parts Quality Using Generalized Linear Models, Foad Hassanmirzaei, Zbigniew Pasek

Industrial and Manufacturing Systems Engineering Publications

This paper presents an approach used for improving the visual quality of body panels produced in an automated press shop of a car manufacturer. To solve the complexproblem of panels’ visual defects,the optimal values of process parameters based on Generalized Linear Models (GLZ) were identified and deployed. The project focused on parts exhibiting excessive rejection rates. To deal effectively with the case in which the distribution function representing the number of defects in the panels was found to be binomial with presence of some covariates in the model, the research approach focused on development of Log it Models.

After identifying …

Simulation-Based Verification Of Lean Improvement For Emergency Room Process, Nancy Khurma, Gheorghe M. Bacioiu, Zbigniew J. Pasek

Industrial and Manufacturing Systems Engineering Publications

One of the key challenges to health care access in Canadian hospitals is growing overcrowding of the Emergency Departments (EDs), leading to the medical personnel overload, and the excessive waiting times to receive proper care. These adverse effects directly impact the patient satisfaction levels, the ability of the medical professionals to attend promptly to patients' health issues, and generate unnecessary costs. Addressing the sources of waste and improving the process provides better care and higher patient satisfaction, as well as increases operational efficiency and the ability of the medical professionals to intervene on time. This paper describes an effort aimed …

An Approach To Line Balancing On Virtual Supervisor Induction Method And Intelligent Agents, J. Trujillo, P. Pawlewski, Zbigniew Pasek, P. Golinska, E. Baeyens, J. Oleskov

Industrial and Manufacturing Systems Engineering Publications

This approach develops a method for solving the line-balancing problem, which is based on two stages. The works in a first stage is to identify the task of workstation, the assignment of the tasks to stations on the line and the recognized balance delay. In this stage we propose the induction VS method, which allows further identify the exact position between pieces, machine into a workstation and also between extern workstation, as well as intracellular and intercellular part. This way each task is identified and measured. In the second stage is to carry out a macro-approach to choose the resource …

On-Line Scheduling Method Of Manufacturing System Based On Vs Algorithm For Reference Pattern, J. A. Trujillo, Clemente Cárdenas, Zbigniew Pasek, Enrique Baeyens

Industrial and Manufacturing Systems Engineering Publications

In this paper, a scheduling method is developed provide planning for manufacturing plants with multiple coordinating cells. The controls for reconfigurable manufacturing systems have to be capable not only of identifying exceptions on-line, but also simultaneously developing on-line strategies for unpredictable customer order changes or inaccurate estimate of processing times. The approach exploits virtual supervisor (VS) concept developing an algorithm which provides access to all system information during program execution and thus can readily monitor the overall system performance creating reference pattern. The goal is to minimize expected costs of part tardiness and/or earliness. A solution methodology based on a …

On-Line Job-Shop Scheduling Of A Manufacturing System Based On A Virtual Supervisor Concept, Jesús Trujillo, Zbigniew Pasek, Enrique Baeyens

Industrial and Manufacturing Systems Engineering Publications

The controls for reconfigurable manufacturing systems have to be capable not only of identifying exceptions on-line, but also simultaneously developing on-line strategies for unpredictable customer orders or inaccurate estimates of processing times. This paper presents an approach for job-shop scheduling with uncertain arrival times. The approach exploits Virtual Supervisor (VS) concept, which provides access to all system information during program execution and thus can readily monitor the overall system performance. The goal is to minimize expected part tardiness and earliness cost. A solution methodology based on a combined Lagrangian relaxation, VS-Patterns, Maxwell equations and temporal difference is developed to obtain …

A New Methodology To Evaluate The Real Options Of An Investment Using Binomial Trees And Monte Carlo Simulations, Michele Amico, Zbigniew Pasek, Farshid Asl

Industrial and Manufacturing Systems Engineering Publications

This paper deals with a new methodology to evaluate the real operating options embedded in a manufacturing system investment. In a single product framework, the demand is assumed as the main source of uncertainty, therefore as a stochastic variable following a geometric brownian motion (GBM). Then, focusing on the real option to expand the capacity at a certain time in the future, we have developed a new approach for the option payoff, looking forward in the time interval from the expansion date to the end of the planning horizon. The payoff function is the expected net present value (NPV), at …
