GARCIA-CACERES, Rafael Guillermo; ARAOZ-DURAND, Julián Arturo  and  PALACIOS-GOMEZ, Fernando. Planning of a Supply Chain for Anti-Personal Landmine Disposal by Means of Robots. Innovar [online]. 2012, vol.22, n.45, pp.51-68. ISSN 0121-5051.

The current paper presents a Mixed-Integer-Linear Programming Model (MIP) which incorporates strategic and tactical management decisions into the supply chain of an anti-personal landmine robotic detection and disposal system. Originally based on a mixed-integer-non-linear programming model (MINLP) with stochastic elements, of which it is an approximation, the MIP model is obtained by means of two solution procedures that include redefining variables, treating stochastic and non-linear constraints, and incorporating valid constraints. The model included considerations such as uncertain procurement, stochastic inventories in plants, production scales, supply-production-distribution capacities, particular distribution-production infrastructure, locationallocation considerations, stochastic demand, and BOM. Additionally, the models detail optimal helicopter operation by considering each period's trip frequency during the planning horizon. Finally, a sensibility analysis of the way in which parameters variations affect overall costs is presented. The suggested solution procedure is considered satisfactory in terms of time for the analyzed example.
