Analysis of water yield service of Lianshui River Basin in China based on ecosystem services flow model

Water security assessment is very important to social development. However, most studies only focus on the status quo of water security in a static state and ignore the flow characteristics of water resources into the water security assessment. This paper integrates multi-source data to construct a water supply and service supply-demand balance and spatial flow model in the Lianshui River Basin, simulates the spatial pattern of the service flow of the aquatic water ecosystem in the Lianshui River Basin from 1990 to 2018, and quantifies the service flow. Results show that (1) From 1990 to 2018, the water supply in the Lianshui River Basin first decreased, then increased, and finally decreased. Water yield was the highest in 2010 and lowest in 2000. (2) Water demand increased year by year, and the amount of area with a poor water resource security index increased, indicating that water security was deteriorating. (3) The four main beneficiary areas in the basin are the urban area of Lianyuan City, the county seat of Shuangfeng County, the Louxing District of Loudi City, and the urban area of Xiangxiang City and nearby towns. The service flow showed the same changing trend as the water yield. In 2018, the water resource gap in the beneficiary area was as high as 4.49 billion m3. Local governments should actively build a water-saving society, improve the efficiency of industrial and agricultural water-saving and residents' awareness of water-saving, and improve the water resources in the river basin. The research can provide a scientific basis for realizing the sustainable development of water resources in the Lianshui River Basin and improving the ecological compensation mechanism, and can also provide references for water resources management in other river basins.

Rationalization of network retail management with a shift trading function based on the mathematical description of processes in the mass service area

The authors highlight the high priority of rationalization in the management of the totality of transactions carried out in the sphere of network retail, in close contact with the service consumer. For network retail objects with a shift trading function, it is important to implement a direct and permanent impact, both on the system structure and on the basic processes in the area of mass trade services. This impact focuses on studying the flow of requests, service inputs and outputs of the system, as well as the length of waiting times, and the length of queues. The success of development in such retail networks depends on the flexibility of the operations performed by the contractor in close contact with the service consumer. It is envisaged to consider peculiarities in the rationalization of network retail management with trade turnover (flexibility) functions. The latter define the structure of the service delivery system for service consumers with processes running, in which client demands for services, as defined in the income chain, even though the intensity of the customer service flow is not constant. The purpose of the research is to present the informative field for rationalization in network retail management with the function of shifting trade, based on the mathematical description and repeated «playing» of all processes within the area of mass service. To represent the informative area for rationalization in network retail management with a shift trading function based on a mathematical description and repeated play of all processes within the public service area, Methods of probability theory and mathematical statistics have been used, as well as cloud computing in AnyLogic Claud environment, AnyLogic service. The results of the study was the presentation of new possibilities for rationalizing network retail management by groups of network objects based on the concept of a mass service area, and in view of the fact that there is an n-channel system of mass service with an unlimited queue, where the request flow has the intensity λ, and the service flow is the intensity μ. The study was implemented with the example of one of the hubs Walmart-Salvador, uniting 90 supermarkets of the company. All Walmart hubs combine only the same supermarket type, supporting the trade changeover function within a single graph (half-yearly). Similar Walmart hubs are developed in Mexico, Great Britain, Brazil, China, Canada, South Africa, Chile, Japan, Costa Rica, Guatemala, Argentina, Honduras, Nicaragua, El Salvador, and Ukraine. At the same time, all network nodes contain objects that apply multi-channel service systems, most common in the network retail with an unlimited queue and an option to add a new service node. It is the Walmart-Salvador hub that has a fairly high percentage of customers’ refusals due to the busy service devices (this estimate ranging from 19% to 25%). As a result, Walmart’s lost annual profit reaches up to USD 25.5 million approximately. The rationalization in the management of the network retail for the Walmart-Salvador hub objects is implemented with a breakdown into 8 groups, united according to common input parameters, the latter providing a solution for the optimal number of service devices, and their required reserve and runoff are calculated, as well as efficient productivity resulting from the consistency of the input and output flows in the service channel and the stability in the mass service system. At the same time, programming for solving the problem of the management rationalization is realized using rate fixing for the basic processes in the area of mass service. In this way, mass service system sustainability is ensured, with the average timing for the application staying in the mass service system being crucial. In particular, implementing such a standard could allow avoiding losses caused by waiting for servicing and unproductive ones. Among other relevant factors are: associated timing, probability or other values (necessary for transformation operations in the characteristics of the mass service area, performed for generating target values of this indicator). Perspectives of implementing the mathematical description of the processes in a mass-service area are in the fact that it will provide for significantly simplification in the processes of rationalizing the retail management in shift-trading facilities, regardless of the frequency of quantity and quality product range changes.

Framing Improvement of Emergency Services RSKJ Soeprapto Hospital with Lean and WAM Modification

The present study reports the first comprehensive research on covid19 emergency services model. Healthcare services inside hospitals during pandemic can apply the Lean Hospital and Waste Assessment Model (WAM) modification, which is a new method that can be used to identify waste in the hospital service process flow and operational of emergency service. The purpose of this study is to provide recommendations for improving emergency services in the covid19 era. The method used in this research is a descriptive qualitative analysis carried out through observing the service flow of patients who will be hospitalized from the emergency, confirming the service flow by in-depth interviews and looking at secondary data and giving a questionnaire on a modification of eight waste relationship at 15 persons expert who understands the emergency service process. The results showed that the critical waste of emergency services at RSKJ Soeprapto hospital is a waste of human skills of 17.5%. The reasons for the emergence above are because the covid19 team has not yet been formed, the absence of special officers to conduct primary triage before the patient enters the emergency unit, and many officers who do not understand the flow of emergency services in the covid19 pandemic era. In order to improve hospital services in the future, it is necessary to form a covid19 team, to develop a standard emergency service guide, to conduct continuous socialization to all the hospital staff through education and training programs, which are recommendations for improving emergency services at RSKJ Soeprapto Hospital Bengkulu in the pandemic era and new normal preparation.

Analisis Kondisi Jalan Rel Kereta Api Pada Lintas Sragen-Solo Berdasarkan Nilai Track Quality Indeks (TQI)

One way to keep the train service flow runs safely, maintenance of railroad geometry is required. Maintenance of railroad tracks uses the Track Quality Index assessment to determine which railroad compartments or corridors are prioritized for repair. The research method used is a quantitative research method. The calculation of the TQI of railroad tracks includes force, height, spoor width and lining. The results of the calculation of the TQI value (manual) give the cumulative total number of standard deviation index is 21.6. While the TQI calculation (mechanical) total cumulative number index standard deviation is 21.2. Based on the results of the TQI calculation, the condition of the railroad tracks can be classified into the criteria for the TQI level II (standard deviation of 20 - 35), namely that the railroad can be passed by trains at speeds of 80-100 km/hour. The railroad maintenance based on the TQI is the repairs to rail compartments or corridors that experience leveling damage in segment 9, lining damage in segment 7, wide damage spoor (gauge) in segments 5,7 and 10 and elevation damage (cant) in segment 3.

A Product Service Supply Chain Network Equilibrium Model considering Capacity Constraints

With the further development of manufacturing servitization, the supply chain established by enterprises has gradually evolved into a product service supply chain. The introduction of service flow has made supply chain management more complicated. In this paper, we build a product service supply chain network composed of raw material suppliers, service providers, manufacturing integrators, and customers. The equilibrium model for decision-makers at all levels is established by variational inequality. In particular, we emphasize the impact of product and service capacity constraints and changes in the product service integration ratio on network equilibrium. The results show that, while capacity constraints on production tend to stabilize and unify the market price, service-related capacity constraints polarize the customer pay price. That is to say, product capability constraints limit the quality of product service systems, while service capability constraints limit the types of product service systems. Furthermore, the introduction of service flow and integration with products creates a more closely networked relationship between the upper and lower layers of the product service supply chain, and an increase in the service proportion will increase the network equilibrium profit.
