There is a variety of operations involved in loading and transporting a container of wheat. One method is to base the process on the existing system used by wheat-grade producers or farmers: wheat is harvested, then cleaned, separated (by size or other characteristics), graded, and bagged either on the farm or at a nearby facility. The bags of wheat are then stockpiled in a warehouse or shipped directly via containers to the facility. During the shipping of containerised wheat, changes in the performance of wheat supply chains (WSC) may be identified beyond the assumptions predicted in a generic planning stage. These changes include factors such as changing demand, the origin of supply sources, distances, and lead times, all which may fluctuate widely resulting in a variety of at times, unexpected transportation costs. Supply chain optimisation models have traditionally treated the WSC with certainty and frequently ignore unpredicted events such as disruptions and disasters. The objective of this paper is to provide a mitigation framework for both maritime service operators and users that can respond to various maritime disruptive events when managing a containerised WSC. This paper applies a maritime disruption model constructed for use in an Australian- Indonesian WSC context, which incorporates a WSC simulation, available data, and judgments from practitioners in order to quantify a disruption level arising from the contribution of situational attributes to maritime disruptions. In this paper, a Markovian-based methodology is the prime means used to evaluate the WSC mitigation strategies. The results of the continuous time period of the Markov chain application suggest that optimised mitigation strategies include the measurement and prediction of WSC costs and time functions over a one-year period.
