Objective: Factors influencing long-term viability of an intermediated regional food supply network (food hub) were modeled using agent-based modeling techniques informed by interview data gathered from food hub participants.

Background: Previous analyses of food hub dynamics focused primarily on financial drivers rather than social factors and have not used mathematical models.

Method: Based on qualitative and quantitative data gathered from 22 customers and 11 vendors at a midwestern food hub, an agent-based model (ABM) was created with distinct consumer personas characterizing the range of consumer priorities. A comparison study determined if the ABM behaved differently than a model based on ...

The recent increase in demand for regionally produced food has resulted in a need for more efficient distribution methods. To connect regional food producers and consumers, intermediated regional food supply networks have developed. The intermediary, known as a regional food hub, serves as an aggregation point for products and information. It may also act as a filter to ensure that the requirements of both producers and consumers are consistently met. This paper describes an empirically based agent-based model of a regional food network in central Iowa that is intermediated by a food hub. The model was used to test a ...


Market Competition And Social Welfare Analysis For E10 And E85 With A 1 Game Theory Model, Minwen Yang, Guiping Hu Jan 2013

With the increasing concerns about the petroleum reserve, and the global warming, people have been looking for renewable and environmental friendly energy sources to supplement and replace fossil fuels. Ethanol has been an appropriate substitute to fossil fuels. Currently, E10 and E85 are two of the main transportation fuels with ethanol and they are competing in the market. This study investigates the competition between E10 and E85 with an oligopoly Cournot model and derives three indicators from the equilibrium to measure the performance of the market: E85's market share, E85 price premium which indicate the consumers' additional willingness to ...
