 Design and development of an LPP model for food grain procurement: a case studyM.R. Ganesh, B.M. Rijas and T. Radha Ramanan International Journal of Operational Research, 2025, vol. 54, issue 3, 393-411 Abstract: Indian public distribution system is unique in many respects. It involves various activities like paddy procurement, warehousing, transportation, processing and distribution of rice grains through fair price shops. This paper studies the present system of food grain procurement until its distribution of rice grains at FPSs and develops a conceptual model followed by a linear programming problem (LPP) model with reasonable assumptions. Based on the understanding of the existing conceptual model, the paper designs a new supply chain procurement network by integrating paddy procurement and its distribution. A mathematical model of the designed network is developed as an LPP model with the objective of minimising the transportation cost. The study's uniqueness is two-fold; firstly, the development of an LPP model for the procurement system and secondly is about proposing the fair price shops as the procurement centre instead of the existing mechanisms. The study finds that the proposed supply chain procurement network can minimise the transportation cost by 21%. Keywords: conceptual model; network design of network; distribution; linear programming problem model; LPP; transportation cost.
