Stats

Part of DLCPs focuses on generating realtime and historical stats. Numbers calculated include downtime, acceptance rates as well as overall equipment effectiveness (OEE), a crucials statistic in the manufacturing sector to ensure optimal equipment usage.

Realtime monitoring and alerts

DLCP tracks realtime and historical cycle times. It has two ways of triggering alerts. First, through once values fall outside of automatic z-score based ranges, and second once a user specified manual or relative tresholds are reached. DLCP can alert using email, SMS and browser push.

Inventory

DLCP also is able to track various assets and their bill of materials. It can track incoming delivery orders. It shows inventory status based on real stock levels as well as based on conversions through bill of materials. It also supports multiple warehouses and indicates where the stock is kept.s
