“…System dynamics has also been applied to investigate various complex systems in ecology, economics, management, and other fields ( Honti et al, 2019 ). By comparing different scenarios, researchers can focus on the development of a single discrete event and conduct a behavioral analysis of the overall development dynamics to improve their understanding of complex systems ( Forrester, 1994 ).…”

Rural toilet retrofitting (RTR) is a complex, dynamic system that is affected by many factors and the positive/negative feedback relationships between subsystems and variables. Traditional technologies and management methods face challenges in fundamentally describing and solving problems in RTR. To bridge this gap, this study utilizes system dynamics and causal loop diagrams to explain such problems based on data collected from the stakeholders of the RTR in Jiaozhou from 2018 to 2019. Specifically, this study examines the RTR system from the perspectives of household users, wastewater treatment plants, local governments, grassroots promoters, operation and maintenance personnel, toilet supplier and construction teams, and fecal sludge end users. The factors and processes involved in RTR are identified, and the feedback and relationships among its major stakeholders are established. Results show that the motivation of farmers to engage in RTR is a key variable that affects their final decisions regarding retrofitting and maintaining toilet functions. Meanwhile, the important variables related to the feedback and relationships among the major stakeholders of RTR are mostly focused on policies, subsidies, technology, satisfaction, and cooperation. A scientific analysis method and the updated RTR plan for toilet revolution are then formulated to promote the implementation of RTR in developing countries.

“…The SDA is in fact a methodological tool suited to study and manage complex systems characterized by feedback mechanisms. These can be considered as interconnections describing the self-organisation of the sustainability-related system; in other words, how it changes, adapts, and reorganises itself in response to the environment, including policy and decision-making processes [33][34][35]. In operational terms, a Causal Loop Diagram (CLD) was drawn using the Vensim PLE 7.2a software to visualise the complex array of feedback loops in the system.…”

The adoption of rare, traditional crops represents a good example of enhancing functional agrobiodiversity, not only to provide benefits for farmers but also for society as a whole. The study outlined in this paper aims to verify how and under local social-ecological conditions the combination of organic cereal farming and growing of durum wheat landraces can be profitably applied. Focusing on Sicily as one of the most developed cereal systems existing in southern Italy, the study deployed a comparison between data from the regional dataset by the Farm Accountancy Data Network (FADN) and the data provided by the Association of farmers called Simenza. Thereafter, we used a System Dynamics Approach (SDA) for a better understanding of the main drivers which will most likely affect the profitability of the system in the medium and long term. The results clearly demonstrated how the durum wheat organic system under investigation might still develop under the push of an increasing relative economic advantage between standard varieties and landraces.

“…Thus, we know that many scholars just focused on the investment economy, and less on the factors of the c value. The System Dynamics (SD) method can be combined with qualitative and quantitative methods [53], with functions such as simulating nonlinearity, high-order calculation, and multivariate analysis, to achieve macroscopic and microscopic dynamic examination [54][55][56]. Therefore, this paper takes the social and economic benefits of NEV's battery second use in energy storage as the source of value.…”

Second Use Value of China’s New Energy Vehicle Battery: A View Based on Multi-Scenario Simulation

et al. 2020

Nowadays, many countries are actively seeking ways to solve the energy crisis and environmental pollution. New Energy Vehicle (NEV) has become an important way to solve these problems. With the rapid development of NEV, its batteries need to be replaced with new batteries after 5–8 years. Therefore, whether the second use of NEV’s battery has commercial or social value becomes a research hotspot. The innovation of this paper is to use the cost-benefit method to determine the value influencing factors of NEV’s battery second use, and use system dynamics to perform scenario simulation analysis. The methods used in this paper are the cost-benefit method and system dynamics method. Firstly, this paper systematically analyzes the cost and benefit factors that affect the second use value of China’s NEV batteries and uses system dynamics to establish the relationship and value model among various factors. Then, this paper compares the value of battery energy storage between old batteries and new batteries. According to the cost-income factor analysis, this paper eventually selects specific factors and uses VENSIM software to carry out the multi-scenario simulation. The results show that NEV’s battery second use has commercial and social value compared to new battery energy storage. Moreover, battery cost, government subsidies, and electricity prices are three important factors that affect the second use value of China’s NEV battery. Changing the government’s cash subsidy methods, such as providing free batteries or combining new energy to reduce on-grid tariffs, will help increase the second use value of the NEV battery. In the future, the second use value of China’s NEV battery industry will be more significant, with the update of the technology, the surge in the number of NEV’s used batteries, and government support.
