Understanding the Diffusion of a Mobile Application for Supply Chain Management: A System Dynamics Approach

An appropriate information and logistics structure is of paramount importance for the local fresh food supply chain, which is characterized by market fragmentation and little coordination among suppliers and customers. Mobile communication technologies can help meet this goal because of their large diffusion and real time information management. In this context, a System Dynamics model is developed to study the diffusion pattern and the impacts of a new application for mobile devices supporting supply chain operations. To this end, a reference supply chain in Northern Italy has been considered. The base application and the integration of three additional features assisting in the management of product traceability, electronic payments, and time-sensitive deliveries are analyzed. Simulation results provide insights into the dynamics of adoption of the mobile service and help derive business policies to disseminate its diffusion

System Dynamics Modelling and System Analysis Applied in Complex Research Projects - the Case of VALUMICS

VALUMICS is a Horizon 2020 project funded by the European Commission (2017-2021). The project structure is highly integrated and transdisciplinary, building on the expertise of over 30 specialists in various fields of research including knowledge integration through systems analysis and system dynamics modelling, food science, supply chain management, life cycle assessment, logistics, economics and social science. The aim of the project is to analyze the dynamics of food supply- and value chain systems using a structural analysis including system analysis and perform system simulations using system dynamics. The VALUMICS research approach and the project design are explained and it is justified why system analysis is needed to obtain an understanding of the complex connections and interactions of the distinct parts of food systems. Patterns will be recognized and thus causes and effects of complex relations within the selected food supply system and networks will be identified. This understanding of the functioning of the system can in turn be used to identify policy interventions

System Dynamics Simulation to Test Operational Policies in the Milk-Cheese Supply Chain Case study: Piar Municipality, Bolivar State, Venezuela.

With the purpose of detecting the impact that variations of demand cause in the milk-cheese supply chain, and determining how the operational policies of capacity, inventories or labor force can mitigate this impact, a system dynamics simulation model has been designed based on a survey conducted on a sample of cheese manufacturers and their links with milk farms, transportation companies and cheese distributors. This supply chain will be consolidated when a milk center that will collect the raw milk is completed. From this center, and after adequate treatment, milk will be distributed to the different cheese manufacturers in the supply chain. Managing adequately the milk-cheese supply chain represents an important challenge due to the short life of these products. Although this study was done in a region in Latin America, its results can be applicable to food supply chains by introducing some modifications. The milk-cheese supply chain in this case study contemplates three milk producers, one milk center, five cheese producers and several distributing agents. These companies operate individually under normal conditions, but they have understood that their integration in a supply chain improves the competitiveness of all its members. That is to say, the sum is greater than the parts. For its initial design a simulation software model is used in which the resources of the supply chain are optimized. Later the product of this optimization facilitates some initial values to be used in the system dynamics model in which causeeffect or influence relationships have been previously established considering the most representative variables. Finally, changes in operational policies that can reduce the level of pending orders in the supply chain are tested using other simulation software. The main contribution of this research is that it can serve as support or contribute to reduce the uncertainty in the decision making process of the supply chain management due to the speed with which individual or combined policies can be analyzed. In response to a variation of demand the most adequate policy may be selected and that can be done before the policy is implemented

Development of a dynamic simulation model for inventory level optimization through supply chain

System dynamic is an approach to understanding the behavior of complex systems over time. Current research on system dynamics modeling in supply chain management focuses on inventory decision and policy development, time compression, demand amplification, supply chain design and integration, and international supply chain management. Less attention has been devoted on the inventory level improvement with fuzzy demand controller in dynamic simulation model. This study is aimed to consider customer demand fluctuation to improve the finished goods inventory level of Electronic Company by using dynamic simulation model. Dynamic and changes in demand and corresponding excess during time through the product life is considered as serious problems in supply chain. Data collection and analysis have been considered to find the current problems of the company. Dynamic model has been constructed by ITHINK software to represent the inventory level of company. The stock and flow diagrams are become visible to represent the structure of a system with more detailed information. Three different variables have been applied in Fuzzy controller to give the better level of inventory by MATLAB SIMULINK. Generated results have been compared by current company inventory level in ITHINK software and the best alternative was selected to suggest the company management

Supply chain dynamics

Thesis (M. Eng. in Logistics)--Massachusetts Institute of Technology, Engineering Systems Division, 2003.Includes bibliographical references (p. 121-123).The strong bargaining power of major retailers and the higher requirements for speed, service excellence and customization have significantly contributed to transform the Supply Chain Management. These increasing challenges call for an integrated and dynamic Supply Chain Management and for a better integration and alignment with key customers, in order to reduce the firm's time-to-market and build competitive advantage. The thesis aims at providing the partner company, a major player in the consumer goods industry, with a more robust and efficient vendor managed inventory practice, so that the partner can determine the optimum inventory level to satisfy turnover, service level and lead time requirements, whereas minimizing lost sales and total costs in the system. The team developed a Supply Chain Dynamics framework to help the partner to establish new service level strategies, strongly oriented to the strategic importance of its products and customers, and to map the key system-wide drivers that impact the overall number of inventory turns, service level and total costs. Additionally, in order to run simulations and estimate the outcomes of the proposed recommendations, the team developed a "Multi-Echelon" simulator and used a commercial "Supply Chain Dynamics" simulator.by Ricardo Wagner Lopes Barbosa [and] Edward Fan.M.Eng.in Logistic

THE DYNAMICS OF SUPPLY CHAIN INTEGRATION: EMPIRICAL EVIDENCE FROM PUBLIC HEALTH SUPPLY CHAINS IN KADUNA STATE, NIGERIA

The Kaduna State supply chain transformation initiative aims to integrate all state-fragmented supply chains to improve medicine availability performance. Supply chain integration enables organisations to collaboratively work with medicine suppliers and customers to achieve cost savings and improve service delivery, lead times, and performance. This study empirically assesses public healthcare supply chains and builds a dynamic theory of integrated healthcare supply chains based on systems dynamics. Underpinned by systems engineering theory and the system dynamics integrative paradigm, this study used interplay paradigm crossing in a mixed-method multiple case study to measure the availability of medicines in five public healthcare supply chains and developed a dynamic hypothesis from the mental models of system actors to increase the Medicine Fill Rate (MFR). Constraints in each supply chain were analysed to understand the perception of the structure, feedbacks, and dynamic behaviours that drive medicine availability. A network conceptual model was used to design a three-tiered stock-and-flow model for an integrated supply chain. Policies for financial management, government funding, order management, and inventory management were developed and tested to achieve a 90% MFR. The findings of this study show that the five supply chains can benefit from integration by forming strategic alliances with suppliers for pooled procurement. Sharing resources, risks, and benefits through the adoption of digital platforms to improve communication, visibility, and trust serves as a fulcrum for network integration. The use of supply chain finance and a performance-driven approach by the integrated network assists in breaking the capability and bailout trap of resource dependency on government funding. This study enriches the development of a dynamic theory of supply chain integration that will benefit managers, essential medicine stakeholders, donors, and policymakers by developing network-revolving fund model policies to reduce medicine stockouts and increase essential MFR for the treatment of diseases
