Leveling tool, the batch-building box has the challenge of compensating for the vagaries of production and taking into account the time of change of series.

Introduction

Also called ” Wait Box1, the batch building allows you to create “batches” of Kanban cards. The stakes are varied:

  • To either slow down or accelerate production.
  • Provide for important series change times.
  • Set up batches of part(s) in the case where for the downstream workstation, X parts A and Y parts B are necessary to make part C.

The batch Building Box is located between the sequencer of the workstation and the levelling box.

Feature of the batch Building Box

Each column represents a product family and each slot represents a Kanban.

The size of the economic batch

With the help of the columns, we will create a batch of Kanban representative of the economic batch . As the time of change of series is important, it takes a minimum number of Kanban to start a production.

The minimum trigger threshold

As the production progresses, the Kanban will be added to the board. If the downstream workstation moves slower than the upstream workstation, the Kanban will amonceler and will lose the priorities. To do this, using a color code, the table can indicate priorities and indicate an alert threshold. This threshold corresponds to the time for making products available to customer2.

For example, if customers are to be delivered twice a day or all 8hr, the time between the workstation and the storage area is 4hr. So the alert threshold is 4hr.

Whatever the result of the calculations to identify the number of Kanban per batch and the thresholds of alerts, these parameters will be adjusted by the experimentation.
