| 内容記述 | (Abstract)Having a solid verification program that ensures a “system is built right” playsa crucial role in both government and commercial space programs, since eventhe smallest error in a requirement, design/analysis, test, or inspection at every level of a system development, could cause a major system post-launch failureor costly finding of latent problems late in system’s development phase.Since the dawn of space age that started with Soviet Union Sputnik in 1957and U.S. Explorer in 1958, space systems development activities have experienced a series of maturing processes; however, it became evident that a system engineering-centric centralized-verification approach was mainly used by the U.S. industry throughout its history. Unfortunately, this traditional centralized-verification approach was found to be rather ineffective for minimizing/preventing such costly problems as finding a unit deficiency during a higher level system integration & test phase or in worst case the loss of space or launch vehicles after launch. The main reason for this was that thorough anddetailed verification at each phase and at every level of system development was missing under the traditional centralized-verification approach because of the magnitude and complexity of general space systems that were acquiredunder perennial budget constraints.This paper examined the space and launch vehicles post-launch failures data that have been collected by The Aerospace Corporation since 1960ies and found that almost all of the post-launch failures could have been prevented, if their problems had been discovered prior to the shipment of these vehicles to their launch sites In particular, it was found that the majority of these vehicles could have been successful, if deficiencies were corrected during early phase (requirement and design phases), or lower system level (unit and subsystems) of their systems developments; Hence, the study further points out theweakness associated with the traditional centralized-verification approach andthe need for improvement.This paper presents a systematic approach for planning and executing verification of space systems based on a newly developed distributed-verification approach that corrects fundamental deficiencies associated with the traditionalcentralized-verification approach. This newly developed distributed-verificationapproach enforces a standardized modular-management process, which contains a set of six specific verification management processes, to be adopted at every level and phase of space system development activities.The newly developed distributed-verification approach also tries to preventinfamous “Faster, Better, Cheaper” or “Total System Program Responsibility(TSPR)” philosophy, from being unintentionally adopted at each level of a space system development due to schedule and cost pressures.This newly developed distributed-verification approach is now explained in aU.S. DoD best practice document and also included in a core standard of TheAerospace Corporation. It has also been adopted as a compliance document in some major U.S. space programs such as the next generation GPS Block III,and some national security space programs. It is also currently studied by U.Sgovernment-industry working group under the direction of its senior executivecommittee for the purpose of upgrading it to a government standard. | |||||||||
