The Defense Advanced Research Project Agency (DARPA), in conjunction with the U.S. Navy, initiated a research program for the design and construction of a distinctive warship for the 21st century known as the Arsenal Ship. By using an innovative development and acquisition approach it was hoped to streamline the procurement process and reduce costs. In an environment where budgets are being cut, both industry and Government were challenged to develop, design, and produce the innovative ship and related mission systems to meet specific performance capabilities within strict affordability constraints. A key element of this innovative acquisition approach was a new certification scheme designed to replace the traditional test and evaluation (T&E) and acceptance process. The purpose of this paper is to describe the development of the certification plan during Phase LI of the Arsenal Ship program by the American Bureau of Shipping and the contending Shipyard teams, and to discuss the potential benefits of this alternative certification approach. Although the Arsenal Ship program was canceled late in 1997, insight derived from the exploration of new certification concepts could benefit future design and building programs.

The development of the economic sector is determined by services to the public through reforms that aim to place public satisfaction through the management of road infrastructure assets. Some research on road infrastructure assets still requires a deepening of studies related to the delivery of public services related to asset management systems. The purpose of this study is to find an appropriate road infrastructure asset management strategy through an integrated asset management system and asset management policies that can provide public satisfaction. This comprehensive approach to management strategies ensures that the performance of service provider assets is in line with the expectations of stakeholders including road users. This descriptive qualitative research is based on the perspective of road users as respondents, consisting of vehicle drivers from 50 transportation companies (people or goods) through interviews and observations. The results show aspects of asset performance based on the user's perspective there are five aspects, namely productivity, efficiency, effectiveness, use of resources and institutions and this performance is integrated in the asset management system related to policies from the management authority through service delivery namely quality and mobility, risk and use and maintenance of resources. The conclusion of this research is that road infrastructure asset services can be improved through the concept of road infrastructure asset management strategies in an integrated management system with five aspects of performance and more directed towards asset management policies related to the provision of road infrastructure asset services.

Evaluating the physical quality of soil (SPQ) at the watershed scale is crucial for improved management and conservation of soil and water within the watershed. This study aims to assess the spatial uncertainties of soil physical vulnerability (SPV), based on the characterization of the distribution and spatial variability of physical-hydric attributes (PHA), using geostatistical simulation within the established sample grid in the Santa Rita watershed (SRW), located in Pelotas, Rio Grande do Sul, Southern Brazil. Variability and spatial distribution were assessed using the Matheron estimator and the sequential Gaussian simulation (SGS) method, respectively. Uncertainties of macroporosity (Ma), bulk density (Bd), and saturated hydraulic conductivity (Ks) were evaluated based on cumulative frequency distribution curves and coefficient of variation mapping from simulations. The SPV was assessed by integrating different critical zone maps based on Ma, Bd, and Ks. Among the studied attributes, Ks exhibited the highest heterogeneity. SGS effectively characterized the variability and spatial distribution of Ma, Bd, and Ks, identifying critical areas and developing maps highlighting zones with compromised soil quality. Ks required more simulated random fields, while Ma presented fewer uncertainties. The spatial uncertainties for SPV were minimal, despite using different combinations of PHA in the assessment. Soils under native forest showed a lower tendency for physical degradation, whereas soils under crops and native field in the southern portion of the SRW exhibited a higher tendency for physical degradation. Mapping SPV is crucial for assessing SPQ, identifying areas prone to fragility, and promoting sustainable soil and water management. © 2023, The Authors. All rights reserved.

The increase in aircraft noise is an inevitable impact of Halim Perdanakusuma Airport (HLP) commercial operations since 2014. The perception of noise risk from people living around airports is a factor that must be considered for formulating strategic, comprehensive airport noise control plans and policies, and participatory. The purpose of this study is to analyze the noise conditions and the perception of environmental noise risk to the perception of socioeconomic risks that live around the HLP Airport. The results of the WECPNL calculation in area of Jaticempaka and Makasar was ranged between 73.80—79.72. The environmental noise risk of the community in HLP Airport's vicinity was studied from knowledge aspects, perception aspects, and behavior aspects. Most of respondent were in the moderate category of environmental noise risk knowledge and environmental noise risk perception. While for environmental noise risk behavior aspects most respondent were in the low category. The social and economic risk perception for most respondent were in the moderate category. The conclusion of this research is that the community settlements in HLP Airport's vicinity at the distance of 300 m and 600 m does not meet the environmental noise standard for a residential area which is regulated at 55 dB(A). The ideal area for settlement use in the vicinity of HLP Airport is Makassar area which is located 600 m from HLP Airport's runway.

Soekarno-Hatta International Airport is prone to various environmental problems. The problem of population growth has an impact on increasing economic activity which directly impacts the environment. In every production activity from the environmental side, it will bring up the carrying capacity of the environment and the carrying capacity of the environment or ecological footprint. The problem will be difficult if it turns out that the ecological footprint that occurs exceeds the capacity of the existing environmental carrying capacity, also for airport problems. This will result in the airport being unsustainable. This article will discuss the model of the airport environmental footprint that is currently occurring at Soekarno-Hatta International Airport by utilizing the opinions of respondents who live and have activities around the airport. The factor analysis method is used to process the respondent's data to obtain the factors that influence the environmental footprint and then through these findings a model can be developed which is expected to be able to abstract the current conditions. The research results show that the dominant environmental footprint at Soekarno-Hatta airport is overload airport activities impact, operational slot time optimization, and renewable of airport energy, which can then be built as an instrument to evaluate, build and develop airport control policies that are environmentally friendly and sustainable.

In an oil drilling area, there are two oil drilling companies that have obtained permits to drill. As time goes by, the availability of existing petroleum decreases. To anticipate natural resources the government only prioritizes one company. Competition occurs between the two of them to explore petroleum from the ground so that they can drill. The purpose of this study is to provide an overview, how to make a system dynamics model related to the problem of oil drilling as an increasingly limited natural resource, by taking the case of the relationship between drilling companies in facing business competition. The method used is system dynamics with a standard model of mutual difficulties (drifting goals). The result obtained is a system dynamics model that can be used to demonstrate the behavior of a simulated petroleum drilling model to get an overview or condition of the limitations of petroleum and future availability.

AN APPLICATION OF TOTAL QUALITY management AT AN INTERMEDIATE MAINTENANCE ACTIVITY

引用

NAVAL ENGINEERS JOURNAL 1990年第6期102卷 35-43页

作者： NEEDHAM, WD USN is currently assigned as the Pacific Submarine Force maintenance officer in Pearl Harbor Hawaii. He is a 1972 Magna Cum Laude graduate of Duke University with a BS in mechanical engineering a 1983 graduate of Central Michigan University with an MA in business management and a 1986 graduate of MIT with an MS in materials science and an OE in ocean engineering.

The current budget and resource constrained fiscal environment mandates positive measures to improve productivity. The management practices of the last four decades are no longer valid. The Department of Defense (DoD) has issued broad guidelines for a restructuring of all subordinate commands and agencies called total quality management (TQM). The precepts of TQM are not new. They are the very same precepts prescribed by numerous management and quality control experts for the past decade to reverse the downward trends in the productivity of American industry. The program elements of TQM are broad in scope, as they must be for an organization as large and diverse as DoD. The implementation of TQM at the local command level is left to the local commander. This is no mean task, as TQM is a radical departure from traditional management practice in every aspect of an organization. This article reports on the implementation of TQM at a local command, the USS Hunley , a naval auxiliary support ship whose primary mission is the repair and maintenance of a squadron of nuclear-powered submarines in Norfolk, Virginia.

IOP Conference Series: Earth and Environmental Science 2021年第1期622卷

作者： W Mustika A Kadir E Ngii M Nurdin Post Graduate Program Engineering Management Science Halu Oleo University Kendari Indonesia 93121 Department of Civil Engineering Faculty of Engineering Halu Oleo University Kendari Indonesia 93232 Department of Chemistry Faculty of Mathematics and Natural Sciences Halu Oleo University Kendari Indonesia 93232

This study is a follow-up of nickel slag waste used for building construction materials. Paving blocks were made using a mixture of cement and aggregates in a ratio of 1: 3 and 1: 5 which used a mixture of nickel slag waste and natural sand with aggregate gradation in zone III of the rather fine sand category based on SNI 03-2834-2000. Sand substitution with nickel slag waste has used a variation of the composition of the mixture of 0% (without slag), 25%, 75%, and 100% (without sand). The behaviour would be obtained the compressive strength value of paving blocks and average water absorption. Paving blocks compressive strength were tested at the age of 28 days, while the average value of water absorption was performed by immersing the paving block specimens for 24 hours. The physical strength and absorption value of paving block water refer to SNI 03-0691-1996. The results showed that the use of nickel slag waste in making paving blocks could increase the compressive strength of paving blocks, while water absorption in all compositions and variations of the paving blocks mixture was decreased in line with the increase of nickel slag composition.
