E-mandi implementation based on gale-shapely algorithm for perishable goods supply chain

In this paper, we propose to transform the traditional agricultural trading into an electronic exchange between the farmers and consumers in the agricultural supply chain. Preferential evaluations of buyer and supplier satisfactions are mathematically modeled and this preference matrix is given as input to Gale Shapely matching algorithm. The results of m*n matching happens to be a very transparent approach in a bilateral e-trading environment. These results are compared with the results obtained using simple English auction method which produces Pareto-optimal matches. It is found that the proposed method produces stable matching, which is preference-strategy proof and it also reduces the need for number of rounds of allocation.
