Resilience based importance measure analysis for SoS

In a system of systems(SoS),resilience is an important factor in maintaining the functionality,stability,and enhancing the operation effectiveness.From the perspective of resilience,this paper studies the importance of the SoS,and a resilience-based importance measure analysis is conducted to provide suggestions in the design and optimization of the structure of the SoS.In this paper,the components of the SoS are simplified as four kinds of network nodes:sensor,decision point,influencer,and target.In this networked SoS,the number of operation loops is used as the performance indicator,and an approximate algorithm,which is based on eigenvalue of the adjacency matrix,is proposed to calculate the number of operation loops.In order to understand the performance change of the SoS during the attack and defense process in the operations,an integral resilience model is proposed to depict the resilience of the SoS.From different perspectives of enhancing the resilience,different measures,parameters and the corresponding algorithms for the resilience importance of components are proposed.Finally,a case study on an SoS is conducted to verify the validity of the network modelling and the resiliencebased importance analysis method.

Redesign Facility Layout with a Kaizen Approach in Testing Laboratory at Balai Pengujian&Sertifikat Mutu Barang Makassar

In trading activities,especially exports in the food commodities sector,several documents must be made and completed by exporters,such as Certificate of Quality,Test-Certificate,and Chemical Analysis.Balai Pengujian&Sertifikasi Mutu Barang Makassar is a government agency operating in South Celebes that tests the quality of various agricultural and plantation commodities.From year to year,demand for testing services has increased along with the number of exports.So,testing activities have changed in terms of facility layout requirements resulting in overwhelmed in carrying out the testing process.Test rooms are not connected based on the current testing flow causing the tester’s ineffective work patterns.This study aims to redesign the layout of the facilities in the testing laboratory with the Kaizen approach to support the smooth testing process.The results of this study indicate that the proposed floor area uses a 150% allowance so the calculation requires a floor area of 42.52 m^(2).After that,an analysis of the proximity of the facilities is carried out by making ARC(Activity Relationship Chart)and ARD(Activity Relationship Diagram).Based on ARD,a template is made for the layout of testing laboratory facilities.This study applies Kaizen theory with the 5S concept to obtain a neater design,namely Seiri and Seiton in the refreshment laboratory and weighing room,Seiso on testing equipment in all testing laboratory rooms,Seiketsu and Shitsuke applied to all rooms in the testing laboratory.

China’s alfalfa market and imports: Development, trends, and potential impacts of the U.S.-China trade dispute and retaliations

This study examines the development and trends of China’s alfalfa market and imports, identifies key factors for the rapid increase in China’s alfalfa imports, and discusses potential impacts of the U.S.-China trade dispute and retaliations on the alfalfa markets and trade in both nations. China’s rapid transition toward larger-scale commercial dairy production, with enhanced feed and cost management as well as quality and safety control, and its limited resources for high-quality alfalfa production are key factors for the dramatic increase in its alfalfa imports, from 19 601 metric tons in 2008 to 1.38 million metric tons(mmt) in 2018. While the United States dominated China’s alfalfa imports with an average share of 97.01% from 2007 to 2017, the share dropped to 83.76% in 2018 and 63.28% in January 2019 due to the trade dispute and retaliations started in 2018. China will likely remain a large importer of alfalfa because of both its growing demand and the comparative advantages of imported alfalfa in quality and price, but the imports from the United States will be highly affected by the ongoing trade dispute and negotiations. China is also expected to make more efforts to reduce its dependence on U.S. alfalfa through increased investment in domestic alfalfa production and identification of alternative sources of alfalfa and other hay imports.

Magnetite Quartzite-Type Iron Ores – China's Most Important Current Iron Ore Source

China is abundant in iron-ore resources, with proven ore reserves of 576.62×10^8 t and proven reserves of 210×10^8 t, containing an average iron content of 33%. However, the rich iron-ore reserves of 10.85×10^8 t only account for 1.9% of all proven reserves. China＇s iron-ore resources are characterized by many lean ores and a few rich ones.

The Current Situation and Development of Grain Storage Technologies and Facilities for Chinese Farmers

In China, the quantity of farmer＇s grain storage covers about 40% of the total grain yield every year. While, the losses of farms＇ grain storage are up to 8%, which is due to the lack of grain storage facility and technology. The losses of farmer＇s grain storage could reach nearly 20 million tons every year. In this paper, the current situation and development of grain storage technology and facility for Chinese farmers were presented. And a series of policy and research work for reducing the losses of farms＇ grain storage was introduced. The large scale farmers are now developing quickly in China, the new storage warehouse and mechanized facility should be developed adaptively. So, the new storage technology and policy to meet the need of large scale farmers were also introduced in this paper.

Design of Natural Children’s Recreational Spaces and Facilities in Urban Neighborhood Parks

Taking into account problems existing in urban children’s recreational spaces, this paper mainly discussed the method to design natural children’s recreational spaces and facilities, analyzed the characteristics and influencing factors of natural children’s recreational spaces and facilities based on the characteristics of behavioral and psychological cognition of preschool children, and concluded that children’s recreational spaces consist of five parts, namely, the border, entrance, internal activity space, viewing space and supporting space and that the design of recreational facilities should meet the four points of naturalness, appropriate fuzziness, appropriate scale and size, and diversities and opportunities, with a view to providing a reference for the design of children’s recreational spaces and facilities.

China’s electronics and machinery exports have witnessed rapid development since China expanded its electronics and machinery exports as a strategic policy in its foreign trade development in 1985. Similarly, electronics and machinery imports also maintained their growth pace in line with China’s national economic development. China’s electronics and machinery trade with foreign countries stood at US$19.97 billion in 1985, with exports taking US$1.68 billion and imports US$18.29 billion. By the year 1994, China’s electronics and machinery

Beijing's Imports Take Off

Beijing’s foreign economic and tradedepartment has devoted muchattention to the import business, whilecontinuously increasing its export value.In 1994 the value of its self-managedimports(excluding the imports it handledfor the state and provincial foreign tradecompanies as agent)stood at US＄1.91billion, up 38. 2％ over the previous year,remarkably higher than the growth rate ofexports. Of the imports, the means ofproduction and the means of livelihoodwere valued at US＄1.854 billion andUS＄57. 31 million, accounting for 97％and 3％ of the total respectively.
