Research on the allocation decision of emergency material productivity reserve under the cooperation between the government and the enterprise

It is difficult for the general market supply to satisfy the huge emergency material demand under disruption events, which can be met by the productivity reserve. In this paper, we take the government as the main responsibility for emergency supplies under the premise of mutually beneficial cooperation between the government and the enterprise, and we establish a multi-objective programming model of storage quantity that satisfy the goals of timeliness, coverage level and cost with the aim of exploring the proportion of physical reserve and productivity reserve. We use an example to illustrate the feasibility and effectiveness of the model and the results suggest that the model can satisfy the goals and bring a cost saving. Besides, it is also concluded that with the demand increasing, the reserve quantity remains unchanged after rising, while the proportion of productivity reserve remains unchanged after dropping. The model provides a reference for the work of contingency reserve.
