Abstract

A server system may receive two or more Quality of Service (QoS) dimensions for the multi-objective optimization model, wherein the two or more QoS dimensions include at least a first QoS dimension and a second QoS dimension. The server system may maximize the multi-objective optimization model along the first QoS dimension, wherein the maximizing includes selecting one or more pipelines for the multi-objective optimization model in the software architecture that meet QoS expectations specified for the first QoS dimension and the second QoS dimension, wherein an ordering of the pipelines is dependent on which QoS dimensions were optimized and de-optimized and to what extent, wherein the multi-objective optimization model is partially de-optimized along the second QoS dimension in order to comply with the QoS expectations for the first QoS dimension, and whereby there is a tradeoff between the first QoS dimension and the second QoS dimension.

First claim

What is claimed is:

1. A method for automating a run-time adaption of a multi-objective optimization model in a software architecture, the method comprising:
accessing the multi-objective optimization model, wherein the multi-objective optimization model is configured to access one or more library components that are configured based on a user data schema;
receiving two or more Quality of Service (QOS) dimensions for the multi-objective optimization model at run-time,
wherein at least one of the two or more QoS dimensions correspond to a response time, latency, throughput, availability, or success rate,
wherein the two or more QoS dimensions include at least a first QoS dimension and a second QoS dimension;

maximizing the multi-objective optimization model along the first QoS dimension at run-time,
wherein the maximizing includes selecting two or more pipelines for the multi-objective optimization model in the software architecture based on the first QoS dimension and the second QoS dimension,
wherein the maximizing further includes ordering the two or more pipelines based on at least one of the two or more QoS dimensions,
wherein the multi-objective optimization model is partially de-optimized along the second QoS dimension, and
whereby there is a tradeoff between the first QoS dimension and the second QoS dimension;

detecting a predicted change in performance or a predicted output of the multi-objective optimization model; and
transmitting a notification indicating the predicted change.

2. The method of claim 1 , further comprising:
retrieving data associated with a historical output of the multi-objective optimization model;
receiving one or more inputs from an environment-monitoring agent, wherein the environment-monitoring agent receives information on at least one of: resources of a system, concepts of the multi-objective optimization model, data corruption, and data availability to the multi-objective optimization model;
determining a change in at least one of: the resources of the system, the concepts of the multi-objective optimization model, the data corruption, and the data availability to the multi-objective optimization model;
determining whether the change in the at least one of the resources of the system, the concepts of the multi-objective optimization model, the data corruption, and the data availability to the multi-objective optimization model will cause a predicted output of the multi-objective optimization model to vary more than a predetermined amount;
when the change in the at least one of the resources of the system, the concepts of the multi-objective optimization model, the data corruption, and the data availability to the multi-objective optimization model cause the predicted output of the multi-objective optimization model to vary more than a predetermined amount, identifying one or more remedial measures to the multi-objective optimization model to correct for the change; and
displaying an alert to notify a user of the change in the at least one of the resources of the system, the concepts of the multi-objective optimization model, the data corruption, and the data availability to the multi-objective optimization model and the one or more remedial measures.

3. The method of claim 2 , wherein the predicted output includes at least one of first metrics related to a performance of the multi-objective optimization model in relation to Quality of Service parameters and second metrics related to predictions of the multi-objective optimization model as compared with the historical output of the multi-objective optimization model.

4. The method of claim 2 , further comprising executing the one or more remedial measures to the multi-objective optimization model to correct for the change.

11. A computer-program product tangibly embodied in a non-transitory machine-readable storage medium, including instructions configured to cause one or more data processors to perform a set of actions including:
accessing a multi-objective optimization model, wherein the multi-objective optimization model is configured to access one or more library components that are configured based on a user data schema;
