How To Optimize Knowledge Sharing In A Factory Network, Arnoud De Meyer, Ann Vereecke Sep 2009

How To Optimize Knowledge Sharing In A Factory Network, Arnoud De Meyer, Ann Vereecke

Research Collection Lee Kong Chian School Of Business

Designing a manufacturing network entails devising and managing flows of innovation and know-how—not just determining what to produce and where—and organizing the resulting logistics flows.


Modelling Reconfigurable Manufacturing Systems With Coloured Timed Petri Nets, Lianfeng Zhang, Brian Rodrigues Jun 2009

Modelling Reconfigurable Manufacturing Systems With Coloured Timed Petri Nets, Lianfeng Zhang, Brian Rodrigues

Research Collection Lee Kong Chian School Of Business

Reconfigurable manufacturing systems (RMSs) have been acknowledged as a promising means of providing manufacturing companies with the required production capacities and capabilities. This is accomplished through reconfiguring system elements over time for a diverse set of individualised products often required in small quantities and with short delivery lead times. Recognising the importance of dynamic modelling and visualisation in decision-making support in RMSs and the limitations of current research, we propose in this paper to model RMSs with Petri net (PN) techniques with focus on the process of reconfiguring system elements while considering constraints and system performance. In view of the …


Towards A Single European Sky, Yael Gruksha-Cockayne, Bert De Reyck Jun 2009

Towards A Single European Sky, Yael Gruksha-Cockayne, Bert De Reyck

Research Collection Lee Kong Chian School Of Business

We describe an integrated decision-making framework and model that we developed to aid EUROCONTROL, the European air traffic management organization, in its vital role of constructing a single unified European sky. Combining multicriteria decision analysis with large-scale optimization methods, such as integer programming and column generation using branch and price, our model facilitates the process by which the numerous European aviation stakeholders evaluate and select technological enhancements to the European air traffic management system. We consider multiple objectives and potential disagreements by stakeholders regarding the impact of proposed system enhancements and allow for different priorities for each key performance area. …


Deterministic Chaos In A Model Of Discrete Manufacturing, John J. Iii Bartholdi, Donald D. Eisenstein, Yun Fong Lim Jun 2009

Deterministic Chaos In A Model Of Discrete Manufacturing, John J. Iii Bartholdi, Donald D. Eisenstein, Yun Fong Lim

Research Collection Lee Kong Chian School Of Business

A natural extension of the bucket brigade model of manufacturing is capable of chaotic behavior in which the product intercompletion times are, in effect, random, even though the model is completely deterministic. This is, we believe, the first proven instance of chaos in discrete manufacturing. Chaotic behavior represents a new challenge to the traditional tools of engineering management to reduce variability in production lines. Fortunately, if configured correctly, a bucket brigade assembly line can avoid such pathologies.


A Petri Net-Based Approach To Reconfigurable Manufacturing Systems Modeling, Linda L. Zhang, Brian Rodrigues Jan 2009

A Petri Net-Based Approach To Reconfigurable Manufacturing Systems Modeling, Linda L. Zhang, Brian Rodrigues

Research Collection Lee Kong Chian School Of Business

Reconfigurable manufacturing systems (RMSs) have been used to provide manufacturing companies with the required capacities and capabilities, when needed. Recognizing (1) the importance of dynamic modeling and visualization in decision making support in RMSs and (2) the limitations of the existing studies, we model RMSs based on Petri net (PN) techniques with focus on the process of reconfiguring system elements while considering constraints and system performance. In response to the modeling difficulties identified, a new formalism of colored timed PNs is introduced. In conjunction with colored tokens and timing in colored PNs and timed PNs, we further define a reconfiguration …


Maximizing Throughput Of Bucket Brigades On Discrete Work Stations, Yun Fong Lim, Kum Khiong Yang Jan 2009

Maximizing Throughput Of Bucket Brigades On Discrete Work Stations, Yun Fong Lim, Kum Khiong Yang

Research Collection Lee Kong Chian School Of Business

One way to coordinate workers along an assembly line that has fewer workers than work stations is to form a bucket brigade. The throughput of a bucket brigade on discrete work stations may be compromised due to blocking even if workers are sequenced from slowest to fastest. For a given work distribution on the stations we find policies that maximize the throughput of the line. When workers have very different production rates, fully cross-training the workers and sequencing them from slowest to fastest is almost always the best policy. This policy outperforms other policies for most work distributions except for …
