Fuzzy Discrete Event Systems under Fuzzy Observability and a test-algorithm [article]

Daowen Qiu, Fuchun Liu
2007 arXiv   pre-print
In order to more effectively cope with the real-world problems of vagueness, impreciseness, and subjectivity, fuzzy discrete event systems (FDESs) were proposed recently.  ...  Also, we use this computing method to check the existence of supervisors in the Controllability and Observability Theorem of classical discrete event systems (DESs), which is a new method and different  ...  S P / G equals the degree of s belonging to the prefix-closure of the fuzzy language marked by the supervised fuzzy system S P / G under the effect of observable projection.  ...

Design and Implementation of System Under Test for LTE Protocol Conformance Testing

Yin Chen, Zhizhong Ding, Dingliang Wang, Teng Huang
2015 Journal of Communications  
However, all the test suites developed in TTCN-3 language can not be run without building up a development environment which should connect with the System Under Test (SUT), the target to be tested.  ...  The main idea is that the software SUT implemented in TTCN level needs not to simulate all the details of the System Simulator and UE depicted in standard test environment, but only implements some necessary  ...  The main task of Test Execution (TE) Test System User TM TL SA PA CH CD TE System Under Test (SUT) TCI TRI Fig. 2.  ...

Sequential Testing Policies for Complex Systems Under Precedence Constraints

Wenchao Wei, Kris Coolen, Roel Leus
2012 Social Science Research Network  
We study the problem of sequentially testing the components of a multi-component system to learn the state of the system, when the tests are subject to precedence constraints and with the objective of  ...  A solution is a testing policy, which is a set of decision rules that describe in which order to perform the tests.  ...  Summary In this paper, we have examined different classes of testing policies for k-out-of-n systems under general precedence constraints.  ...

System for automated fatigue crack growth testing under random loading

1985 International Journal of Fatigue  
Procedures have been developed for computer-controlled crack propagation testing under random load sequences.  ...  They include certain features which are not available in conventional systems, but which appear essential for random load testing.  ...  Crack extension under such loading occurs predominantly under the larger load cycles.  ...

A Two-Plan Sampling System for Life Testing Under Weibull Distribution

Muhammad Aslam, Saminathan Balamurali, Chi-Hyuck Jun, Munir Ahmad
2010 Industrial Engineering & Management Systems  
A two-plan sampling system is proposed for a failure-censored life testing when the lifetime follows a Weibull distribution with known shape parameter.  ...  It has been observed that the proposed system requires only a single failure for the observation.  ...  A single sampling plan under a failure censored (type-II) or a time censored (type-I) scheme is usually adopted for a life testing.  ...

Test model coverage analysis under uncertainty: extended version

I. S. W. B. Prasetya, Rick Klomp
2021 Journal of Software and Systems Modeling  
AbstractIn model-based testing, we may have to deal with a non-deterministic model, e.g. because abstraction was applied, or because the software under test itself is non-deterministic.  ...  Consequently, performing precise test analyses, e.g. to calculate the test coverage, are not possible..  ...  As a running example, consider the labelled transition system (LTS) in Fig. 1 as a model of some system under test (SUT). The system interacts with its environment through actions a, b, and c.  ...

Test Pattern Ordering and Selection for High Quality Test Set under Constraints

Michiko INOUE, Akira TAKETANI, Tomokazu YONEDA, Hideo FUJIWARA
2012 IEICE transactions on information and systems
