- A Production Line that Balances Itself,
with John J. Bartholdi, III. We describe Bucket Brigade Production
Lines and show how they can be made self-balancing. Operations
Research 44(1), 1996, special issue on ``New Directions in Operations
- Dynamics of 2- and 3-Worker
``Bucket Brigade Production Lines'', with John J. Bartholdi, III
and Leonid A. Bunimovich. We detail the dynamics of 2- and 3-Worker
Bucket Brigade Production Lines and give necessary and sufficient conditions
for small lines to be self-balancing. Operations Research
- Performance of Bucket Brigades
When Work is Stochastic, with John J. Bartholdi, III and Robert
D. Foley . We describe Bucket Brigade Order Picking and its implementation
at several sites. Operations Research 49 (5) , 2001 .
- Separating Logistics Flows in the Chicago
Public School System, with Ananth. V. Iyer. We describe
a model and implementation of improving the logistics of the central
Chicago Public School Warehouse Operation. Operations Research 44 (2), 1996.
- Garbage Collection in Chicago --- A Dynamic
Scheduling Model, with Ananth. V. Iyer. We describe
a statistical model and Markov decision model of the Chicago City
Garbage Collection Problem. Management Science 43 (7), 1997.
- Analysis and Optimal Design of Discrete Order Picking
Technologies Along a Line, Aug. 2006. Submitted.
- Recovering Cyclic Schedules Using
Dynamic Produce Up-To Policies. We describe a policy that recovers
cyclic schedules. Operations Research 53(4), 2005.
- Chaos and convergence in bucket brigades with finite walk-back velocities with J. Bartholdi and Y. F. Lim, working paper 2005. A mathematical analysis showing that if a
bucket brigade is configured pathologically then fully chaotic
behavior is possible.
- Bucket brigades on in-tree assembly networks. with J. Bartholdi and Y. F. Lim (2006), The European Journal of
Operational Research 168(3):870-879,
special issue on balancing assembly and transfer lines. This
shows how to use bucket brigades on a "tree" of merging
sub-assembly lines so that all the sub-assembly lines are
balanced and, moreover, they are all synchronized so that the
assembly network produces product at regular, predictable
- Using bucket brigades to migrate from craft manufacturing to assembly lines. with J. Bartholdi (2005),
Manufacturing and Service Operations Management
7(2):121-129. A case study describing how a
manufacturer of tractors used bucket brigades to migrate from
craft assembly (one person assembles one tractor) to a
semi-automated assembly line.
- Analysis and optimal design of discrete orderpicking technologies along a line. We describe the optimal way to locate depot(s) and layout items along a pick line.
