This study proposes strategies for vaccine center allocation for coronavirus disease (COVID) vaccine by determining the number of vaccination stations required for the vaccination drive, location of vaccination station, assignment of demand group to vaccination station, allocation of the scarce medical professional teams to station and number of optimal days a vaccination station to be functional in a week.

The authors propose a mixed-integer nonlinear programming model. However, to handle nonlinearity, the authors devise a heuristic and then propose a two-stage mixed-integer linear programming (MILP) formulation to optimize the allocation of vaccination centers or stations to demand groups in the first stage and the allocation of vaccination centers to cold storage links in the second stage. The first stage optimizes the cost and average distance traveled by people to reach the vaccination center, whereas the second stage optimizes the vaccine’s holding and storage and transportation cost by efficiently allocating cold storage links to the centers.

The model is studied for the real-world case of Chandigarh, India. The results obtained validate that the proposed approach can immensely help government agencies and policymaking body for a successful vaccination drive. The model tries to find a tradeoff between loss due to underutilized medical teams and the distance traveled by a demand group to get the vaccination.

To the best of our knowledge, there are hardly any studies on a vaccination program at such a scale due to sudden outbreaks such as Covid-19.

In recent times, there has been some disquiet within certain sectors of the Singapore business community over the role of auditors in detecting corporate fraud. The cause of this concern can perhaps be attributed partly to the Barings collapse in February 1995 and the subsequent suggestions that the auditors of the Barings subsidiary in Singapore, Barings Futures Singapore Pte Ltd (BFS), may have been negligent in their audit work. More recently, in mid‐1996, a substantial locally listed company, Amcol Holdings Ltd (Amcol), was placed under judicial management amid rumours alleging possible misdeeds by senior executives and directors. The Amcol saga has, once again, focused some attention on the role of auditors and their duty to detect fraud in company accounts.
