System and method for condition based maintenance

A maintenance management system for condition-based maintenance, the maintenance management system comprising at least an storage and retrieval system comprising a framework structure with a rail system forming a three-dimensional storage grid structure for storing a plurality of storage containers for storing items, where the grid structure forms vertical storage columns having a horizontal area defined by size of an access opening between rails of the rail system that are arranged on the framework structure, the rail system providing available routes for container handling vehicles handling and transferring the plurality of storage containers to and from the storage columns, at least one container handling vehicle which has a container handling platform with a set of grippers for handling the plurality of storage containers, the grid structure comprising one or more ports for extracting the plurality of storage containers from the storage grid so that the plurality of storage containers are adapted to be picked and a service station for performing maintenance on a plurality of components of the storage and retrieval system, wherein the storage and retrieval system comprises a plurality of sensors attached to the plurality of components of the storage and retrieval system for providing the condition-based information linked to parts and the plurality of components of the storage and retrieval system and wherein the maintenance management system further comprises:

• a service regime manager comprising at least one processor configured to retrieve the condition-based information from the plurality of sensors and create a service regime based on the condition-based information linked to the parts and the plurality of components of the storage and retrieval system and send the service regime to a local service station where condition-based maintenance is performed, wherein the service regime controls at least when the parts and/or plurality of components are to be repaired or replaced, and the maintenance management system further comprising:
• a central computer system comprising at least one processor and memory storing instructions which, when executed, are configured to:
• receive and analyze the condition-based information from the plurality of sensors and determine which of the condition-based information is to be sent to a global computer system for condition-based maintenance, and further sending only the condition-based information having a potential interest to other storage and retrieval systems,
• the global computer system comprising at least one processor configured to receive the condition-based information from the central computer system, determine one or more trends regarding component servicing or changing of components, and further transfer information relating to the one or more trends to the central computer system's service regime manager.
