Designing international development projects is challenging because the complexity of the systems on which they act makes it difficult to identify the best leverage points for intervention. This paper seeks to identify the best combinations of interventions to increase the availability of and demand for quality seeds in Uganda and similar markets. A system dynamics model simulates the current dynamics in Ugandan seed markets based on data gathered by ongoing development projects. The findings show that one intervention is critical to enabling growth—investing in a system for verifying the quality of seeds—and that a combination of quality verification with education-oriented interventions is more powerful than quality verification alone. The results have implications for systems approaches to development: they suggest that a combination of interventions in different parts of the value chain enables larger changes than any single intervention alone.

Dealing with problems in complex environments that impede organizational cohesion, information dissemination and coordination is extremely difficult nowadays. Usage of technology without sophisticated information sharing planning and solid processes that serve with a bottom-up approach the needs of each individual within an organization, undermines time, cost and quality of deliverables. The eG4M (e-Government for Mediterranean Countries)project basically concentrates on extending, completing and improving the e-Model through the achievement of new research results and its application by participating with the support of the Mediterranean Countries (MCs) – in establishing and consolidating their e-Government systems. This paper focuses on the development of a generic system dynamics model that illustrates the behavior of e-governance systems based on the VSM (Viable Systems Model) as well as the development of a web, collaborative intelligent framework that is built upon the system dynamics model. The framework is meant to have the form of a web-based simulation that is able to identify critical issues related to product, customer, information sharing and service quality using visualizations, automated analytics and impact analysis delivered with natural language format to support the systemic reengineering process, mitigate risk, predict issues during the planning phase and help the user understand complexity and inform his decisions with predictive insights. Modeling the behavior of an e-governance system and being able to automatically process complex relationships, data and issues upon this system mitigates uncertainty at all levels, increases awareness and understanding of the real world and delivers sustainability and viability, increases growth and sets the basis for process autonomy and better coordination, controls and quality of deliverables.

Unstable States

The article presents the statement of the problem, models and algorithms for controlling the welding process via robotic technological complexes in conditions of the risk of unstable states. The system dynamics model was used to describe the technological process. As system levels the basic indicators influencing quality of the made production chosen on the basis of experience of operation of the robotic technological complexes are taken. Functional dependences between indicators and their dependences on external factors are determined by approximation of statistical data. The procedure of identification of unstable states for the mathematical model on the example of the Rossler’s attractor is developed. An algorithm for preventing the system from falling into unstable states in the process control is proposed

Social Rewards

Using Indian free-ranging dogs (FRD) as a case study, we propose a novel intervention of social integration alongside previously proposed methods for dealing with FRD populations. Our study subsumes population dynamics, funding avenues, and innovative strategies to maintain FRD welfare and provide societal benefits. We develop a comprehensive system dynamics model, featuring identifiable parameters customizable for any management context and imperative for successfully planning a widescale FRD population intervention. We examine policy resistance and simulate conventional interventions alongside the proposed social integration effort to compare monetary and social rewards, as well as costs and unintended consequences. For challenging socioeconomic ecological contexts, policy resistance is best overcome by shifting priority strategically between social integration and conventional techniques. The results suggest that social integration can financially support a long-term FRD intervention, while transforming a “pest” population into a resource for animal-assisted health interventions, law enforcement, and conservation efforts.
