Abstract For the satellite Control system, product assurance work is evaluated from design process, production development testing and validation subsystem acceptance test process of under spacecraft. This paper mainly describes quality control model system quantifying results management, obtaining accurate assessment data final reliability system.

Introduction: The evaluation of X-ray and light field coincidence in linear accelerators as a quality control test is often performed subjectively, involving the manual marking of films and their visual inspection following the irradiation. Therefore, the present study aimed to develop an objective method for the performance of this test leading to the increased levels...

This article proposes a model for identifying quality requirements based on three different views of quality. By specifying quality requirements in this manner, the framework establishes quailty requirements that can be quanitfied and measured as part of an overall quality assurance program. This results in two levels of quality: one at the system level that ensures a quality software product a...

In 2003 a working group established on the initiative of the Centre of Information Technology of Education under the Ministry of Education and Science, has been reviewing regulations for the assessment and certification of educational software. This article analizes the main aspects of the proposed orders. It discusses general structure of quality assurance system, the procedures for the certif...

1 1 This is an updated version of the guidelines presented to the Committee for the Coordination of Statistical Activities (CCSA) at its meeting in September 2009 [CCSA, 2009]. It takes into account comments received from members of the CCSA and as well recent developments on quality. The aim of the document is to further support the work of the CCSA for enhanced quality assurance of statistica...

Models have begun to play an important role in environmental assessment and urban climate studies. Their increasing use, however, is paralleled by a growing awareness that the majority of these models have never been the subject of rigorous evaluation. Consequently there is a lack of confidence in the modelled results. The paper reports on a European initiative (COST 732) which was launched 200...
