Parallel Test Execution for Device Segments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current testing systems for devices, including missiles, require sequential execution of tests, leading to increased testing time and potential conflicts between tests, which can be time-consuming and inefficient.
Innovation Solution
The development of apparatus and methods that allow for the parallel execution of tests, monitoring the testing environment to ensure that tests do not interfere with each other, and pausing tests until necessary data is available, thereby optimizing test execution and reducing overall testing time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If tests are executed sequentially, then test conflicts are avoided, but testing time increases significantly
Solution Approach 1:
The testing system dynamically determines whether to execute tests sequentially or in parallel based on real-time analysis of test dependencies and environmental constraints. The system continuously monitors test execution states and adjusts the execution schedule to maximize parallelization while preventing conflicts, thereby reducing overall testing time without compromising reliability.
Solution Approach 2:
The system implements feedback mechanisms by continuously monitoring test execution states, environmental conditions, and data availability. This feedback enables the testing system to make real-time decisions about test scheduling, allowing it to switch between sequential and parallel execution modes as needed, thus optimizing both time efficiency and execution reliability.
2Loss of time
If tests are executed in parallel, then testing time is reduced, but test interference may occur
Solution Approach 1:
The testing system segments tests into different execution groups based on their dependency relationships and resource requirements. By dividing the test suite into independent segments that can be executed in parallel without interfering with each other, the system achieves time reduction while maintaining execution reliability through proper segmentation of test workflows.
Solution Approach 2:
The system introduces an intermediary scheduling layer that manages test execution by analyzing dependencies, monitoring environmental conditions, and coordinating resource allocation. This intermediary component acts as a mediator between parallel test executions, preventing interference while enabling concurrent execution to reduce overall testing time.
3Productivity
If more devices are tested, then testing coverage increases, but total testing time increases proportionally
Solution Approach 1:
The system merges multiple device testing operations by executing tests on multiple devices simultaneously in parallel. By combining test execution resources and coordinating test schedules across multiple devices, the system increases testing coverage without proportionally increasing total testing time, as tests on different devices can run concurrently rather than sequentially.

AI summary
Test systems coupled to a device under test (DUT) with different segments or stages and related methods are provided. Exemplary test systems include logic that executes concurrent determinations or tests for multiple DUT segments or stages. Exemplary test systems can include logic that concurrently executes various tests associated with different DUT segments including determinations or testing for a specified DUT test environment, determinations or tests of when data will be made available to various DUT segments, and various determinations or tests that may be completed before data is made available to specified DUT segments. At least one embodiment of a first stage concurrent determination test system determines first stage tests do not require a specified target and high pressure gas conditions for DUT testing and at least one embodiment of a second stage concurrent test system does require a specified target and high pressure gas conditions for DUT testing.
