System and method for manufacturing system data analysis

A method for manufacturing system operation, comprising:

• receiving, from a manufacturing system, a data stream indicative of manufacturing process parameter values throughout a time interval, wherein at least one manufacturing process parameter value of which the data stream is indicative was sampled by a sensor of the manufacturing system during the time interval;
• generating, based on the data stream, a set of histogram-preserving digests, wherein, for each histogram-preserving digest of the set, the histogram-preserving digest is generated using a respective histogram-preserving digest compression, wherein each histogram-preserving digest of the set is associated with a respective subinterval of the time interval and a respective set of manufacturing process parameters;
• receiving a query associated with the manufacturing system, wherein the query defines a query time interval and a set of dimensions, the query time interval comprising a first subinterval and a second subinterval;
• and
• in response to receiving the query:
• based on the query, selecting a plurality of histogram-preserving digests from the set such that the respective subintervals associated with the plurality of histogram-preserving digests are disjoint, wherein:
• the respective subintervals associated with a first subset of the plurality of histogram-preserving digests define a partition of the first subinterval;
• and
• the respective subintervals associated with a second subset of the plurality of histogram-preserving digests define a partition of the second subinterval;
• providing a query result based on the plurality of histogram-preserving digests, comprising:
• generating a query-specific digest, comprising merging the histogram-preserving digests of the subset;
• and
• providing the query result based on the query-specific digest;
• and
• based on the query result, controlling maintenance of the manufacturing system, comprising:
• based on the query result, identifying a set of components of the manufacturing system that have an elevated probability of defective operation;
• and
• in response to identifying the set of components, selecting at least one component of the set of components for at least one of:
• inspection or repair.
