Your tool for analyzing and illustrating simulation results


Easily recognize relations and interdependencies

GBU-Gantt clearly displays the interplay of your processes and thus supports you in the process improvement.

  • Track orders and their usage of resources.
  • At GBU-Gantt each resource (staff, room, equipment) is assigned a row. On these resource rows the operations carried out are chronologically shown.
  • In addition, the associated resource states (working, setup, waiting, blocked, down) can also be displayed.
  • Tailored to varying questions you can scale the time axis and select relevant resources.

Read the results intuitively

  • User-specific attributes (such as waiting time, produtID, ProcessSeq, priority, customer, …) are displayed for each process.
  • Expand the attribute list to your needs with little effort.
  • Based on the attribute values, you can color all processes. At a glance, you will find, for example, long waiting times or recognize orders with high priority.
  • So you can identify dynamic bottlenecks and understand the reasons for non-value-added waiting times.


Excel interface opens multifaceted fields of application

  • GBU-Gantt can be used very efficiently with the simulation tools Process Simulator and ProModel or MedModel.
  • However, process data from other simulation tools (such as Plant Simulation) can also be displayed via the Excel interface.
  • Use GBU-Gantt independently of simulation models. Visualize planning data created in Excel or illustrate real production data.


Used with almost every simulation project

  • We already use GBU-Gantt during project planning.
  • When creating a model, the Gantt evaluation helps to quickly identify model errors.
  • The clear presentation facilitates communication with the project participants.
  • Dynamic bottlenecks can be quickly identified and analyzed.
  • Finally, a Gantt chart illustrates the dynamic processes shown in a presentation.

EasyToUse Template

The quick way to a powerful Gantt evaluation

With the new EasyToUse template, you can extend existing Process Simulator models with a powerful Gantt diagram in just a few steps.

Simply integrate the GBU Gantt template into your existing model via a link.


Analyzing processes in Gantt

Now you can enclose the process time with GG () for the processes you want to analyse in the Gantt diagram.

During simulation run GG () logs the process start and end, as well as the associated attribute values.

Quick results

Evaluate results right after the end of the simulation in GBU-Gantt

At the end of the simulation run you can analyse the resource and employee usage of the processes in the GBU Gantt.

Recognize with the upper status (Legend Top), that due to the concurrent use of the employee "Worker" waiting times arise (yellow upper status for the entities of Type3 at Activity3).
