Expediting is one of the main activities in purchasing for securing timely delivery of material, equipment, and components in strict compliance with the order requirements and the contractually committed quality. Thus, expediting targets ensuring the supply is competently prepared by the vendor in line with the schedule, so that it is delivered at the promised time, at the agreed location and exactly as specified in the order. Expediting bears special importance in the following: Medium- to large-scale projects in which cost of delays are very highAny project in which the schedule is quite tight

The role of expediting is to secure the quality and timely delivery of goods and components. In a manufacturing context, this involves monitoring the progress of manufacturing at the supplier in terms of quality, packaging, and conformity with standards and lead times. Thus the goal is to ensure that the required goods arrive at the appointed date in the agreed quality at the agreed location.

From a system thinking perspective, a SD model that captures capacity disruptions is presented in this study. Full and partial disruptions are considered. In the full disruption, the affected SC echelon cannot produce, place orders or deliver during the disruption time. A similar approach is used by Sarkar and Kumar (2015). In the partial disruption, the SC will continue working but at a lower capacity level and with a higher production cost. Hence, partial disruptions could represent the implementation of mitigation strategies. Additionally, the model considers expediting products after the disruption. Expediting is a common practice that is implemented in the SCs for securing the timely delivery of goods and components. Depending on the echelon, orders are expedited with premium costs. Expediting is commonly achieved using production adjustments (overtime, additional shifts, etc.) and faster transportation options (Schmitt et al. 2017). In this research, production expediting by reducing the production time is considered to mitigate the effects of the disruptions.
