Synchronous
manufacturing |
| Work
order release |
This
work attempts to design methods for work order release decisions in
manually operated manufacturing cells. These cells have to consider
capacity constraints in order to generate feasible sequences. We develop
and test heuristics that are based on insights from assembly line sequencing
and workload control. The project is performed in co-operation with
prof. G.A. Suer from Ohio University. |
| Cellular
manufacturing |
The
research is directed to designing robust and responsive cellular manufacturing
systems. These systems have to be able to coordinate complex relations
with respect to materials, tools and machines and to adapt themselves
to new situations. Attention is given to lay-out, staffing, relations
with engineering and product design, and information systems. |
| Planning
and control |
In
order to synchronize various production systems, planning and control
systems have to be designed that are both easy to use and effective
in establishing the desired synchronization. Principles of the Period
Batch Control planning system can be used in designing new systems for
synchronous manufacturing. The research aims at extending the flow concept
to other partners in the supply chain network. Planning systems should
be able to cope with a modular design of the supply chain and with different
levels and distribution of autonomy. |
| Card-based
control systems: Kanban and Polca |
Many
firms use card-based control systems for controlling the progress of
processes and supporting the decision to release orders to the shop
floor. In order to be effective, these systems need to be selected and
designed carefully. The research is focused on designing a Polca system
for low volume - high variety production systems that cannot be controlled
using standard Kanban systems. |
| Patterns
in Group Technology |
Firms
neeed to change their production systems and be able to apply a different
layout of machines, tools, and employees in cells. Methods that are available
generally are heuristic in nature. We develop improved mathematical models
that support effective decision making in this area. |
| European
region for Innovative Production |
Several
partners in the North Sea region cooperate in order to establish an improved
lean chane methodology for small to medium sized enterprises. Our expertise
on pull system design for make to order companies is very useful for this
project. Moreover, we support the development of this lean change methodology
and help to measure the impact of interventions and implementations. |
Advanced
planning in supply chains |
| Order
crossovers |
Traditionally,
inventory management models assume that orders arrive in the same sequence
as they are issued. However, supply chains become more flexible, reactive
and dynamic. Suppliers are easily interchanged and lead times vary.
Therefore, this assumption is no longer valid. We develop improved models
for managing inventories. Cost improvements of almost 30% were obtained
in a case of a Dutch Tobacco firm. |
| Lot
splitting |
Splitting
a batch in several subbatches leads to a reduced throughput time of
the whole batch, but transfer costs in the supply chain increase. The
research compares the effect of shorter time buckets in the synchronous
planning system with changes in the number of subbatches used. |
| Railway
planning support |
The
organization of the planning process of the Dutch Railways is highly
complex. We are involved in a project called RUG_RINTEL. This project
aims at developing algorithmic support for specific tasks of the planner.
It focuses on integrating these algorithms in a GUI that resembles the
current work environment of the planner. The performance improvements
that can resullt from improved support of the planner are also being
examined. |
| Employee
allocation in projects |
Many
projects can be viewed as one of a kind supply networks. Organizations
that contribute to several phases of projects have to train and develop
their employees in order to be able to maintain their knowledge inventory
for the whole spectrum of phases and markets served. The research aims
at developing tools that help these firms to measure this knowledge
inventory and support them in allocating employees to projects. |

The price of the best
master thesis project of the Faculty of Management and Organization in the
year 2002 has been appointed to Christian den Herder, for his project "Research
and development process and planning" at Ericsson Emmen. I supervised
this study. The project studied the way product development projects that
incorporate blue tooth technology could be improved. Substantial improvements
could be found by introducing new tools to support the project planning. Insights
were used from the ph.d. research project of Bas Oosterman, entitled "
