Maintaining reliability for electrical distribution systems that support processing facilities is a constant challenge due to aging equipment and other factors. Upgrades and replacements require significant engineering, extensive capital, scheduling, and shutdowns. Investment in electrical infrastructure is often marginalized and only addressed upon an unplanned failure or necessary expansion. Without...
Many problems have existed in synthesis design of reliability, maintainability, supportability (RMS) and performance, such as RMS design activities are numerous and optional, variable feedback branches can satisfy same RMS requirement, some iteration among RMS and Performance activities is necessary, and many uncertainty exist in the design process. A process reengineering method for synthesis design...
The continuous operation mode of high equilibrium in the flow construction yields great benefits in lowering the cost and reducing the construction period as well as risks. The change of the construction period of any sub-construction will definitely exert a relatively great impact on the balanced construction of the project. Through the analysis of Monte Carlo simulation method (MC), the assurance...
The software independent verification and validation (IV&V) is essential, especially in the development of aerospace systems, to improve safety and reliability and to prevent system problems. We have used a hierarchical accident method. This method investigates the latent problems in the development process of a system that have not been thoroughly recognized in past IV&V. The National Transportation...
Supply chain event management (SCEM) systems are decision support systems that allow for monitoring, prioritizing and reacting to events pertaining to the flow of goods in a supply chain. A major current trend in logistics concerns the tracking of materials by using the radio frequency identification (RFID) technology. RFID reader data can be contextualized in the form of standardized supply chain...
The successful development and market insertion of a financially successful new product requires technology, marketing, manufacturing, and luck. This paper suggests various steps in the process that are critical to success. More specifically, the paper deals with the special problems encountered by small business. The analysis is presented in light of the Small Business Innovative Research program...
This paper evaluates Weibayes small sample, zero and sudden death failure test and data analysis techniques in order to mathematically and graphically quantify the risk associated with assuming an incorrect value of the Weibull shape parameter, beta (beta). Specifically, the risk associated with assuming a value of beta that is higher than the ldquotruerdquo value of beta is investigated, as this...
How should a company organize a project team to develop new products? This study examined the relative effectiveness of four types of team structures by comparing the performance of 559 development projects in terms of development cost, new product development speed, and product commercial success. The results indicate that in general, autonomous team structure is superior to other team structures,...
An organizational level test strategy needs to incorporate metrics to make the testing activities visible and available to process improvements. The majority of testing measurements that are done are based on faults found in the test execution phase. In contrast, this paper investigates metrics to support software test planning and test design processes. We have assembled metrics in these two process...
ldquoDevelopment for advanced thermoelectric conversion systemsrdquo supported by the new energy and industrial technology development organization (NEDO) has been successfully completed as one of the Japanese national energy conservation projects. Three types of the cascaded thermoelectric modules operating up to 850 K in high electrode temperature and two types of Bi-Te thermoelectric modules operating...
As Grid networks grows, the complexity of resource management in Grid networks dramatically increases. To manage the Grid resources efficiently, policy based resource management system is suitable. However, the policy which made at a moment could not be appropriate to other time because the condition of the grid resources with time space changes. Thus, in this paper, we propose asynchronous policy-based...
