Abstract: The outbreak of the novel coronavirus pneumonia (COVID-19) has caused a great impact on the whole economic and social development. It is an important challenge for local governments to plan the production resumption of enterprises without relaxing the epidemic prevention and control. Based on the experiences of Zhejiang Province in overall planning of epidemic prevention and control and economic development, in this paper, we formulate a production resumption planning problem, which selects a subset of enterprises from a large number of candidates that apply for production resumption and determines their order of resumption under epidemics, so as to satisfy the social demand for industrial capacities as much as possible without violating the constraints such as epidemic spreading risk. To efficiently solve this problem, we propose an improved tabu search algorithm, which uses a greedy strategy to construct an initial solution and continually explores a better solution based on variable neighborhood search. Computational results on enterprise production resumption planning in several regions demonstrates the efficiency of our method.

Key words: production resumption, epidemic prevention and control, optimization, integer programming, tabu search
