Tutorial Objective: This tutorial has two sections. The first section will show you how to use the Clusters feature. Our previous approach to the precedence graph required the user to draw the graph for the entire line. With this version the user can define clusters or groupings of tasks and proceed one cluster at a time instead of the entire line. The second section will focus on the lean (value added/ non value added) graph.
Section I - Clusters
| I. | Begin by opening the MixedPumps.xml scenario and click on the Precedence Graph on the task sheet.Currently the scenario has only one cluster, the Default cluster. |
| II. | Define clusters. We will define two more clusters, say CLS1 and CLS2. In order to do so type the names of the clusters in the Cluster column and click Refresh. |
| III. | Next associate tasks to each cluster. Change the view type to task graph. The list of all tasks will now appear at the bottom. |
| IV. | Now modify the cluster column next to each task. The cluster column now has a drop down list of all the clusters. Click and assign the cluster to the task, the user can also drag and drop the cluster column to assign multiple tasks to the same cluster. |
| V. | Once the clusters have been assigned to tasks, click on the cluster drop down to view tasks that belong to a cluster. |
| V. | The user can now go into each cluster and define a precedence relationship. |
| VI. | Finally define a relationship between the clusters. In order to do the same, change the View Type to Cluster. |
Section II - Lean Graph
The lean graph helps the user visualize the value added work at each station.
| 1. | Define the value, non value and non value added but necessary percentages for each task in the Task sheet. |
| 2. | Once these tasks are assigned to stations, the resulting line balance graph looks like the following. The user needs to check the 'Show VA/NVA chart' box. To get back to the LB graph, simply uncheck this box. |
