A testing platform tests an electrical and mechanical system such as an HVAC unit according to an algorithm that reduces the total testing time of the components of the system, while ensuring the safety of the system during system-wide testing. The platform uses constraints that are checked both before and during the testing to ensure that HVAC operating conditions are acceptable for starting and maintaining component tests. Preferably, the platform uses finite-state machines for each device to organize the component tests, allowing for monitoring of constraints and starting, pausing, and stopping component tests. Preferably, total test execution time is reduced by running component tests in parallel, running component tests based on loads of the components, or combinations of both.

According to some embodiments, system and methods are provided, comprising receiving, at a machine health module, non-parametric data associated with operation of an installed product; generating, via the machine health module, a health status for at least one of a failure type and a remaining useful life of the installed product, based on the received non-parametric data; and generating an operating response of the installed product based on the generated health status. Numerous other aspects are provided.

Systems and methods of generating performance index for connected equipment in a building management system are provided. The connected equipment measures monitored variables and generates status codes. The system obtains data points of the monitored variables and the status codes from past N time units, and connected equipment specific parameters. The system performs first performance checks for the connected equipment using the status codes from the past N time units. The system performs second performance checks using the data points of the monitored variables from the past N time units, the connected equipment specific parameters, and a set of predetermined rules. The system determines individual performance check indicators based on the first performance checks and the second performance checks using first weights each determined based on a different timing. The system generates an overall performance index for the connected equipment using the individual performance check indicators and second weights.

A risk assessment device includes a diagnosis result storage unit that accumulatively stores diagnosis results of a plurality of diagnoses regarding each process device in association with installation sites of the process devices, a calculation model storage unit that stores a calculation model for calculating a probability of malfunction of a process device, a malfunction ratio calculation unit that calculates, based on diagnosis results regarding process devices that are and have been provided at a target installation site, a malfunction ratio that is a ratio of process devices that had malfunctioned by the time a reference period had elapsed from when the process devices were installed at the target installation site, a malfunction probability calculation unit that calculates, based on the calculation model, a probability of malfunction that is a probability that a process device provided at the target installation site will malfunction within the reference period, and a risk index value calculation unit that calculates a risk index value of a process device provided at the target installation site, through comparison between the calculated malfunction ratio and the calculated probability of malfunction.

Methods and apparatus are provided for an integrated vehicle health management system that uses a model based reasoner to develop real-time diagnostic and maintenance information about a vehicle. A model having nodes is used to represent sensors, components, functions and other elements of the system. Parameterized input sensors provide flexible definitions of each node. Once developed, the model is loaded into an operational flight program to provide real-time failure analysis of the vehicle.

A system and method are provided for generating minimal cut-sets for highly integrated large systems. The method includes receiving a system model (102) and a scenario (104), and obtaining a dependency array (300) from the system model (102) according to the scenario, with the dependency array (300) including at least one case (302). The method includes selecting a case (302) in the dependency array (300). The method includes querying a cut-set repository (110) to determine if a cut-set for a component (200) in the case (302) is already stored, and retrieving said cut-set; and if a cut-set is not stored, generating the minimal cut-set for the component (200). And the method includes computing a final cut-set list (112) by expanding the dependency array (300) using the cut-set for the component (200). The method improves the efficiency of cut-set generation applied to manufactured systems with great number of components.
