SYSTEM ACQUISITION

Supercritical fluids were identified in early 1989 as a possible CFC replacement for certain niche applications at Honeywell Space Systems. At that time there was very limited data on either the application of supercritical fluids for precision cleaning or compatibility studies with materials common to the aerospace industry. 

Carbon dioxide was selected as the gas of choice for cleaning of precision guidance instruments. It was the gas most widely discussed in literature, and the solubility of supercritical carbon dioxide was often compared to heptane or cyclohexane which are excellent organic solvents. It was felt that if supercritical carbon dioxide did behave like these hydrocarbons, it could potentially dissolve most contaminants removed by CFC-113. 

Several vendors of supercritical extraction systems were contacted and/or visited by Honeywell to determine if this might be a viable process. Samples of common contaminants and material compatibility coupons were taken to the vendors to determine if supercritical carbon dioxide would be compatible with common

For such major system acquisitions, a more thorough analysis of the system s economics will probably be required. In such a case it is best if those responsible for exploring and/or securing the benefits of LIMS technology, understand the financial decision making process that goes on in the firm and can assess for themselves the value of anticipated benefits and the investment which such benefits would justify. Not only will this insure a judicious system acquisition, but it will develop, in advance, the specific data that the financial decision makers require and which proves the value of the system not just to the labs, but to corporate organization as a whole. 

Figure 2-312 depicts an SLC adapted to different system acquisition strategies and software development models. It is focused on software engineering key practices. It does not specify or discourage the use of any particular software development method. The acquirer determines which of the activities outlined by the standard will be conducted, and the developer is responsible for selecting methods that support the achievement of contract requirements. A modifiable framework must be tailored to the unique characteristics of each project. It includes the following periods ...

Records related to the test system itself (for biological test systems acquisition, condition, suitability testing, etc. for physical-chemical test systems specifications, manufacturer, model, etc.) should be gathered and retained. 

Figure 12.1 shows the 22 MRTFB test and evaluation activities managed by the three military services. Together, they encompass approximately 50% of the DOD land in the continental United States, 243,000 square miles of water surface, and 221,000 square miles of airspace. These activities provide the full spectrum of test and evaluation support for the Department of Defense s major weapon system acquisition programs. Due to their unique capabilities and expertise, these facilities may also be used to support research, development, test and evaluation requirements of other government agencies and private industry. The MRTFB has also been used for military training activities over the years. 

Each Check it is usually based on a configuration file which contains the complete experimental set-up (Fig. 1.6). After starting the simulation the reader will be prompted to define the output file to which the calculated data is stored. If no configuration file exists the pulse program, rf channels, spin system, acquisition and processing parameters have to be chosen by the reader before the simulation is run (Fig. 1.6 left hand side).

The presented model can be used as a tool for assessing availability of critical systems, in favor of an appropriate sizing of teams (operational phase) and definition of parameters needed to achieve the reliability or desired levels of redundancy (design phase), depending on the availability requirements of the systems (acquisition phase).

The safety case is oftentimes divided into an engineering safety case—which focuses on the design and deployment (including testing) of the system and the operational safety case—which focuses on the nominal and emergency operations of the system. Both should consider the entire life cycle from design, build, operations, maintenance, modifications, and disposal and should consider the build and oper-ate/maintain system supply chain. Figure 12.4 illustrates how the system acquisition is considered in the safety case. The illustration taken from EN 50126, Railway... 

A contract is a legal agreement between two or more competent parties. In the systems acquisition process, a contract is typically between the government and a contractor, whereby the contractor develops and produces a product or system for the government. In addition to specified performance requirements, contract requirements include those requirements defined in the statement of work (SOW) specifications, standards, and related documents the Contract Data Requirements List (CDRL) management systems and contract terms and conditions. 

The PESHE document is the means for communicating ESOH risk and status to the SSWG, PM, and acquisition executives. The PM uses the PESHE to identify and manage ESOH hazards, and to determine how to best meet ESOH regulatory requirements. The PM shall keep the PESHE updated over the system fife cycle. As prescribed by DoD 5000 systems acquisition poUdes, the following are the minimum required data elements for a PESHE ... 

The WSESRB provides independent oversight of all ordnance items, weapon devices, systems, ordnance or weapons programs, or weapons support test systems used, handled, stored, or tested aboard U.S. Naval vessels, and ensures that appropriate explosives safety, system safety, and environmental requirements are adhered to. Every DON weapon system acquisition program and all other services weapons system programs representing a system destined to be deployed aboard a U.S. Naval vessel must be reviewed by the WSESRB.
