A Base Stock Inventory Model for a Remanufacturable Product
(2003-01)We report on an industrial project in which we developed an inventory model to provide decision support for the design and deployment of the field service support system for a remanufacturable product. The product was a ... -
The Benefits of Re-Evaluating Real-Time Fulfillment Decisions
(2005-01)At the time of a customer order, the e-tailer assigns the order to one or more of its order fulfillment centers, and/or to drop shippers, so as to minimize procurement and transportation costs, based on the available current ... -
Building a Document Corpus for Manufacturing Knowledge Retrieval
(2004-01)When faced with challenging technical problems, R&D personnel would often turn to technical papers to seek inspiration for a solution. The building of a corpus of such papers and the easy retrieval of relevant papers by ... -
Characterization and Modeling of Chemical-Mechanical Polishing for Polysilicon Microstructures
(2004-01)Long the dominant method of wafer planarization in the integrated circuit (IC) industry, chemical-mechanical polishing is starting to play an important role in microelectromechnical systems (MEMS). We present an experiment ... -
Characterization of Diamond-Like Film after Focused Ion Beam Processing
(2003-01)Optical properties (transmission and refractive index) and chemical structure (XPS) of diamond-like coating (DLC) film before and after focused ion beam milling (FIBM) process, were investigated in this paper. It is shown ... -
Collaborative Engine for Distributed Mechanical Design
(2002-01)Effective collaboration is essential for engineers at geographically dispersed locations to accomplish good design with less iteration. Over the last several years, more and more efforts have been put into such research ... -
The Complexity of Safety Stock Placement in General-Network Supply Chains
(2005-01)We consider the optimization problem of safety stock placement in a supply chain, as formulated in [1]. We prove that this problem is NP-Hard for supply chains modeled as general acyclic networks. Thus, we do not expect ... -
Computer-aided Tooling Design for Manufacturing Processes
(2003-01)Tooling design for manufacturing processes refers to direct tooling for making a part such as molds and dies for injection molded parts and metal stampings, or for supporting machining operations such as jigs and fixtures. ... -
Coordinating Inventory Control and Pricing Strategies with Random Demand and Fixed Ordering Cost: The Finite Horizon Case
(2005-01)We analyze a finite horizon, single product, periodic review model in which pricing and production/inventory decisions are made simultaneously. Demands in different periods are random variables that are independent of each ... -
Coordinating Inventory Control and Pricing Strategies with Random Demand and Fixed Ordering Cost: the Infinite Horizon Case
(2005-01)We analyze an infinite horizon, single product, periodic review model in which pricing and production/inventory decisions are made simultaneously. Demands in different periods are identically distributed random variables ... -
Cycle to Cycle Manufacturing Process Control
(2002-01)Most manufacturing processes produce parts that can only be correctly measured after the process cycle has been completed. Even if in-process measurement and control is possible, it is often too expensive or complex to ... -
Design and Development of 3-DOF Modular Micro Parallel Kinematic Manipulator
(2005-01)This paper presents the research and development of a 3-legged micro Parallel Kinematic Manipulator (PKM) for positioning in micro-machining and assembly operations. The structural characteristics associated with parallel ... -
Direct Fabrication of Planar Grating by Ultrafast Laser Beam
(2002-01)Femtosecond laser pulse has been used for the machining of the gratings primarily due to its superior advantages over conventional continuous wave (CW) and long pulse lasers for micromachining. In this paper, we develop a ... -
Droplet Bouncing Behavior in the Direct Solder Bumping Process
(2003-01)This paper presents the results of an ongoing effort to develop a direct solder bumping process for electronics packaging. The proposed process entails delivering molten droplets onto specific locations on electronic devices ... -
DSS Model for Profit Maximization at Customer Enquiry Evaluation Stage
(2004-01)This paper presents an optimal method and a heuristic approach which aims at maximizing the profit when responding to a set of customer enquiries under limited capacity. The model takes into consideration the quantity of ... -
Dynamic Scheduling of Flexible Manufacturing Systems
(2004-01)To date, group scheduling research has primarily focused on examining the performance of different group heuristics under various experimental conditions. However, the dynamic selection of group heuristics has not received ... -
Efficient Methods for Manufacturing System Analysis and Design
(2002-01)The goal of the research described here is to develop tools to assist the rapid analysis and design of manufacturing systems. The methods we describe are based on mathematical models of production systems. We combine earlier ... -
An Extension to the Tactical Planning Model for a Job Shop: Continuous-Time Control
(2005-01)We develop an extension to the tactical planning model (TPM) for a job shop by the third author. The TPM is a discrete-time model in which all transitions occur at the start of each time period. The time period must be ... -
Facilitating Mechanical Design with Augmented Reality
(2005-01)By enhancing a real scene with computer generated objects, Augmented Reality (AR), has proven itself as a valuable Human-Computer Interface (HCI) in numerous application areas such as medical, military, entertainment and ... -
Factory Models for Manufacturing Systems Engineering
(2003-01)We review MIT research in manufacturing systems engineering, and we describe current and possible future research activities in this area. This includes advances in decomposition techniques, optimization, token-based control ...
