Kanban by Ghent University
This video introduces the module on Card-Based control. The module includes methods like Kanban, Cobacabana, Conwip and POLCA. These different methods can be implemented to limit Work-in-Process (WIP) inventory on the shop floor. The key element is to allocate cards to the items.
This video illustrates the basics of the Kanban method with a very simple example. It is followed by two other videos the further exemplify Kanban. Series done by Ghent University.
Kanban Card Example Part 1
This video is Part 1 of a two that further exemplify Kanban. This video illustrates how to calculate the amount of Kanban cards does the production loop need.
Kanban Card Example Part 2
This video is Part 2 that further exemplify Kanban done by Ghent University. This video illustrates how to calculate the amount of Kanban cards does the production loop need if there are multiple products on the same machine.

Part 1: What is Kanban?
Kanban is Card-Based inventory control system that introduces limitations for Work-in-Process (WIP) inventory. It is an effective tool to support running the production system as a whole and an excellent way to promote improvement.
This video introduces Kanban. It is the first video of a series of 4 done by Osnabruek University.
Part 2: The Basics
This video is the second of a series of 4 done by Osnabruek University. This video gives a brief overview of the lean concept of Kanban. It talks about the Kanban Cards and the information they should carry. The card is the central control of Kanban.
Part 3: Container Kanban
This video is the third of a series of 4 done by Osnabruek University. Kanban relies on the pull principle in production control. The video covers the advantages and disadvantages of the system and the several ways Kanban cards can be used. Also, it talks about C-parts.
Part 4: Production Kanban
This video is the last of a series of 4 done by Osnabruek University. It explains the Kanban process, illustrating the steps in the Kanban loop with an example.
COBACABANA is an acronym that stands for Control of Balance by Card-Based Navigation. COBACABANA is a card-based method based on the concept of workload control (WLC); simple to implement; more suited for job shop environments (i.e. production environments with high routing mix), as compared to Kanban that is essentially dedicated to repetitive production environments.
Part 1: A method to achieve WLC
This is Part 1 of 2 of the lecture about Cobacabana. It explains the logic of Cobacabana and the use of this method to achieve workload control in high-mix, variable routing manufacturing environments.
Part 2: Estimating workload limit for workstations
This is Part 2 of 2 of the lecture about Cobacabana. This video explains how to configure and operate Cobacabana. You will learn how Cobacabana cards translate to workload and the difference between direct and direct workloads.
The video talks about the basic principles of CONWIP and its origins. Also, it cover key aspects of CONWIP implementations.
POLCA stands for Paired-cell Overlapping Loops of Cards with Authorization. POLCA is a shop floor material control strategy. It is a variant of Kanban, especially useful for organizations dealing in a high mix, low volume environment.
The video explains how to design POLCA loops. POLCA loops are created by determining product families, identifying inter-cell traffic and creating a From-to-Table.
The video explains how to calculate the amount of POLCA Cards needed for a loop of two work stations.
POLCA Safety Card
The video explains how to use a safety POLCA card to deal with disruptions in supply.
POLCA Case Study at Variass
This is the last video of a series of 4 videos that explain the POLCA method. The video shows a case study of a Dutch company called Variass where a version of POLCA method was adapted.
We thank Variass for the presentations, video and cooperation to produce this case example of their adapted use of the POLCA system to control the assembly of end products. Variass is a system supplier that develops and industrialises high-tech solutions for clients. (http://www.variass.nl/)
