A Remanufacturing News-Vendor With Pricing And Take-Back Pricing, Keyu LU 2010 Singapore Management University

A Remanufacturing News-Vendor With Pricing And Take-Back Pricing, Keyu Lu

Dissertations and Theses Collection (Open Access)

This paper analyzes the problem of a remanufacturing news-vendor with selling and take-back price decision. In our model, the remanufacturer decides selling price, take-back price, and order quantity for new materials. She then uses the stochastic take-back quantity and the new material to meet the stochastic demand comparably to a news vendor setting. We allow demand and take-back supply to be correlated. In this thesis, we study a production problem with dual input sources: raw materials and recycled or remanufactured take-back items. To answer when mixed-sourcing is best, we analyze the model under deterministic setting first, provide criteria for different …

Aircraft Leasing With Contracts, Qiong ZUO 2010 Singapore Management University

Aircraft Leasing With Contracts, Qiong Zuo

Dissertations and Theses Collection (Open Access)

We study a problem of rental rate pricing and rental contract designing in aircraft leasing industry. In a framework of Stackelberg game, the system is composed of an airline company (carrier) and an aircraft leasing company (lessor). Acting as the leader, the lessor announces daily rental rates and/or provides long-term contracts on a finite horizon with multiple periods. For each period, the carrier determines the aircraft leasing number to adjust the flight capacity, and applies a dynamic pricing policy for air-tickets based on a seasonally stochastic demand and some economic factor, such as oil price. We find the optimal policies …


Accidents Will Happen. Do Safety Systems Improve Warehouse Safety Performance?, Rene B. M. De Koster, B. M. Balk, I Davelaar, M. Martens 2010 Erasmus University of Rotterdam

Accidents Will Happen. Do Safety Systems Improve Warehouse Safety Performance?, Rene B. M. De Koster, B. M. Balk, I Davelaar, M. Martens

11th IMHRC Proceedings (Milwaukee, Wisconsin. USA – 2010)

Safety is becoming more and more an issue in warehouses. In the literature, effective measures leading to increased occupational health and safety have hardly been researched. Most research focuses on the impact of perceived safety-related leadership of managers and worker safety consciousness on ‘safety climate’ and workers’ safe behavior. We have carried out exploratory research into which measures really improve the safety performance of a warehouse. We particularly focus on the effects of (1) safety-related work procedures, (2) safety leadership, and (3) workers’ safety consciousness. Based on a survey we show that safety leadership and safety-related work procedures significantly drive …


Optimizing The Rearrangement Process In A Dedicated Warehouse, Hector J. Carlo, German E. Giraldo 2010 University of Puerto Rico - Mayaguez

Optimizing The Rearrangement Process In A Dedicated Warehouse, Hector J. Carlo, German E. Giraldo

11th IMHRC Proceedings (Milwaukee, Wisconsin. USA – 2010)

Determining the optimal storage assignment for products in a dedicated warehouse has been addressed extensively in the Facility Logistics literature. However, the process of implementing a particular storage assignment given the current location of products has not received much attention in the existing literature. Typically, warehouses use downtime or overtime to remove products from their current location and move them to the suggested location. This work presents the Rearrange-While-Working (RWW) policy to optimize the process of rearranging a dedicated warehouse. The RWW policy seeks to relocate products in a warehouse from the initial arrangement to the optimal arrangement while serving …


A New Milp Approach For The Facility Layout Design Problem With Rectangular And L/T Shaped Departments, Yossi Bukchin, Michal Tzur 2010 Tel-Aviv University

A New Milp Approach For The Facility Layout Design Problem With Rectangular And L/T Shaped Departments, Yossi Bukchin, Michal Tzur

11th IMHRC Proceedings (Milwaukee, Wisconsin. USA – 2010)

In this paper we propose a new approach for the facility layout problem (FLP) and suggest new mixed-integer linear programming (MILP) formulations. The proposed approach considers simultaneously the location of the departments within the facility and the internal arrangement of the machines. Two models are suggested, where the first addresses the rectangular department case and the second allows nonrectangular departments defined by an L/T shape. New regularity constraints are developed to avoid irregular department shapes.


Strategic Design Of A Robust Supply Chain, Marc Goetschalckx, Edward Huang 2010 Georgia Institute of Technology

Strategic Design Of A Robust Supply Chain, Marc Goetschalckx, Edward Huang

11th IMHRC Proceedings (Milwaukee, Wisconsin. USA – 2010)

The strategic design of a robust supply chain has as goal the configuration of the supply chain structure so that the performance of the supply chain remains of a consistently high quality for all possible future scenarios. We model this goal with an objective function that trades off the central tendency of the supply chain profit with the dispersion of the profit as measured by the standard deviation for any value of the weights assigned to the two components. However, the standard deviation, used as the dispersion penalty for profit maximization, has a square root expression which makes standard maximization …


Evaluating The Effect Of Operational Conditions And Practices On Warehouse Performance, Andrew L. Johnson 2010 Texas A&M University

Evaluating The Effect Of Operational Conditions And Practices On Warehouse Performance, Andrew L. Johnson

11th IMHRC Proceedings (Milwaukee, Wisconsin. USA – 2010)

Analyzing warehouse performance across different environments is critical to improving overall productivity and reducing costs. Although two-stage DEA estimators have been shown to be statistically consistent, the finite sample bias of DEA in the first stage carries over to the secondstage regression, which causes bias in the estimated coefficients of the contextual variables. The bias is particularly severe when the contextual variables are correlated with inputs. To address this shortcoming, we apply insights from Johnson and Kuosmanen (2010), who demonstrate that DEA can be formulated as a constrained special case of the Convex Nonparametric Least Squares (CNLS) regression to develop …


Comparing Transport Policies In A Full-Scale 300mm Wafer Manufacturing Facility, J. E. Kiba, S. Dauz`ere-P´er`es, C. Yugma, G. Lamiable 2010 Ecole des Mines de Saint-Etienne

Comparing Transport Policies In A Full-Scale 300mm Wafer Manufacturing Facility, J. E. Kiba, S. Dauz`Ere-P´Er`Es, C. Yugma, G. Lamiable

11th IMHRC Proceedings (Milwaukee, Wisconsin. USA – 2010)

Research in semiconductor manufacturing ideally wants to determine the “best” transport policy to ensure continuous production. Determining such a policy is difficult because it depends on many factors such as the layout, the product types, the equipment, etc. Most of the transport policies found in the literature combine dispatching policies (scheduling of transport requests) and routing policies (selection of the path to move from one point to another). This paper investigates a policy called "minimum service" which consists in keeping a minimum number of available vehicles in bays, so that they can quickly answer transport requests and empty travel times …


The Human-Centric Warehouse, Kevin R. Gue 2010 Auburn University

The Human-Centric Warehouse, Kevin R. Gue

11th IMHRC Proceedings (Milwaukee, Wisconsin. USA – 2010)

In theory and in practice, the objective of warehouse design has long been to meet operational requirements of throughput and service performance at minimum cost. A natural product of this “bottom line” approach has been warehouse buildings and operations ill-suited to the humans who spend their working lives interacting with them. We offer an explanation for the current approach, and argue that a new approach— a new paradigm —is needed. We then describe a comprehensive approach to warehouse design that includes human well-being as a primary goal.


Forklift Routing In Warehouses Using Dual-Commands And Stackable Pallets, Ahmed Hassan, Bill Ferrell 2010 Clemson University

Forklift Routing In Warehouses Using Dual-Commands And Stackable Pallets, Ahmed Hassan, Bill Ferrell

11th IMHRC Proceedings (Milwaukee, Wisconsin. USA – 2010)

This research determines time optimal routes for loading and picking pallets that can be stacked on top of each other during transport in a manual warehouse that only contains full pallets and utilizes single deep storage. This research was motivated by the fact that we are seeing this situation on an ever increasing basis, particularly in warehouses that supply parts to automotive assembly. In practice, forklift drivers have developed strategies to take advantage of this opportunity but to our knowledge there is no literature that addresses this problem rigorously. The important features of this work are that a time based …


Plug-And-Work Material Handling Systems, Kai Furmans, Frank Schonung, Kevin R. Gue 2010 Karlsruhe Institute of Technology

Plug-And-Work Material Handling Systems, Kai Furmans, Frank Schonung, Kevin R. Gue

11th IMHRC Proceedings (Milwaukee, Wisconsin. USA – 2010)

One disadvantage of automated material handling systems is their relative Inflexibility: once racks are installed and conveyors are laid, making even mi-nor changes to a system can be cumbersome and expensive. However, recent progress in the capabilities and cost of basic system components, such as controllers, drives, and sensors, has made possible a new class of material handling systems having a much higher degree of flexibility. We propose underlying de- sign principles for such systems and describe several prototype plug-and-work" systems, which feature decentralized control and ease of reconfiguration.


Control Policies For A Dynamic Storage System With Multiple Lifts And Shuttles, Iris F.A. Vis, Hector J. Carlo, Paloma Diaz, Maria E. Laboy, Bruno vanWijgaarden 2010 VU University Amsterdam

Control Policies For A Dynamic Storage System With Multiple Lifts And Shuttles, Iris F.A. Vis, Hector J. Carlo, Paloma Diaz, Maria E. Laboy, Bruno Vanwijgaarden

11th IMHRC Proceedings (Milwaukee, Wisconsin. USA – 2010)

New types of Automated Storage and Retrieval Systems, able to achieve high throughput levels, are continuously being developed and require new control polices to take full advantage of the developed system. In this paper we study a dynamic storage system as developed by Vanderlande Industries consisting of a conveyor, two lifts, multiple transfer shuttles, and a storage rack. One of the decision problems for this system is the scheduling problem of the two lifts. In other words, which lift is going to handle which request and in which order. In this paper, we derive an integrated look-ahead heuristic based on …

Utilisation Of Foreign Trade Zones In The Global Supply Chain: An Exploratory Study, Hokey Min, Thomas E. Lambert 2010 Bowling Green State University

Utilisation Of Foreign Trade Zones In The Global Supply Chain: An Exploratory Study, Hokey Min, Thomas E. Lambert

Management Faculty Publications

Foreign Trade Zones (FTZs) are considered duty-free areas and, thus, not governed by the usual customs and tariff controls. In other words, the merchandise permitted in the FTZ may be stored, sold, exhibited, labelled, repacked, assembled, distributed and mixed with other merchandise without paying customs duty until merchandise is released from the zone. Deferred customs duties in the FTZs can contribute significantly to the profitability of the Multinational Firms (MNFs) that get involved in global supply chain activities. Thus, the utilisation of FTZs is believed to have a positive impact on export/import operations and the location decisions of MNFs. Despite …
