Question
1) In Kanban, blocking a card means visualizing that something disables the team from performing the task.
The idea behind the card blocking feature is to not be able to move the blocked card until the problem is resolved. Usually, when you block a task, it cannot be moved at all.
Starving on the other hand means, starving the bottleneck. In Kanban system, we sometimes purposely limit work-in-progress and since the work items vary in size; a couple of large items that needs to be processed upstream could end up temporarily starving the bottleneck.
2) In the first step there is a block at the machine 1. It means there is a problem at the machine 1. So, all the buffer that is available is processed by machine 2 and machine 2 becomes idle until the block at machine 1 is not resolved.
In the second step, the machine 2 is starved, which means there is a bottleneck. Since machine 2 is starved because of the bottle neck there should be a buffer to start the system. So, in this case, the machine remains idle because of the bottleneck.
In the third step, both the machines are working properly and the reason for this is, because bottleneck has been buffered. Once buffereing of bottleneck happens, both the machines work.
Explanation / Answer
what does blocked and starving mean? What happens to the kanban in each of the 3 situations? B DC reuuced? Problem 4 (Kanban Systems and Flow Production Lines) Discuss the relation between Kanban controlled flow lines and flow lines with finite buffer capacities with blocking after service mechanism. IlIlustrate your discussion by visualizing the state of a two machine line with saturated demand and supply of raw material for which I. processing of machine 1 is interrupted by organization of material flow 2. machine 2 is interrupted by organization of material flow 3. both machines are working
