MES Systems are difficult to specify, especially if there is no legacy system.You may not have the resources in house, but may not trust an external partner. The entire upgrade may not be worth the effort. Either way, the first place to start is to document how the current production order is generated and executed, and Spike can help with that.
In this set of tutorials, a production order is created for an orange juice plant. By the end of the tutorials, an engineer will have a much better idea of how to scope an MES project. Contact us for a demo. (The tutorials take about 3 days to complete).
