Abstract: A system includes reception of time-series tuples of a first portion of business data, automatic generation of a weighted graph describing relationships between the time-series tuples, automatic generation of one or more causal loop diagrams based on the relationships and on one or more knowledge models associated with the business data, automatic transformation of each of the one or more causal loop diagrams into a respective state flow diagram, automatic annotation of each of the one or more state flow diagrams with parameters and equations, generation of a simulated system based on the one or more annotated state flow diagrams, and evaluation of the simulated system based on a second portion of the business data.

Abstract: The disclosure generally describes computer-implemented methods, software, and systems, including a method for creating and incorporating an optimization solution into a workload placement system. An optimization model is defined for a workload placement system. The optimization model includes information for optimizing workflows and resource usage for in-memory database clusters. Parameters are identified for the optimization model. Using the identified parameters, an optimization solution is created for optimizing the placement of workloads in the workload placement system. The creating uses a multi-start approach including plural initial conditions for creating the optimization solution. The created optimization solution is refined using at least the multi-start approach. The optimization solution is incorporated into workload placement system.
