Abstract: This paper addresses the optimisation of supply chains that are subject to any pertinent conditions of operational uncertainty (multi-objectivity, fuzziness, stochastic's) that may exist in an operational environment, the first part of the paper deals with the derivation of such methodology which is based on an analysis of prior multi-uncertainty level supply chain optimisation techniques followed by the formulation of a generic supply chain, under pertinent conditions of uncertainty and optimisation methodology. The second part of this paper deals with an application of this methodology in a real life supply chain environment that involves the production and distribution of multiple blends of NPK fertiliser in an uncertain market characterised by fuzziness (<, ≤, > or ≥) and multi-objectivity (multiple blends of NPK fertiliser). Optimum results showed an improvement of 9.3% over existing production and sales capacity.
