CLASS is a warehouse design and simulation tool. It allows us to design, evaluate, re-design and test complex warehousing layouts. It also enables the assessment of product through-flow and the organisation of people and equipment to quantify cost, efficiency and service levels.

The main advantage of CLASS is that it enables users to understand the impact of changes to operational flows and methods. By enabling any number of scenarios to be investigated, it allows on-going testing of existing warehouse operations.
