In this scenario, the firm will store the herbal medicine in their storage for a maximum of two weeks if there is excess production. The overproducing takes place when the demand is less than batches. For example, the demand from the branches throughout Malaysia is 2500 bottles per month, and the firm can produce 3000 bottles due to the machine’s capacity. Therefore, the balance of 500 bottles will be stored in the storage for the next demand. The production situation will reflect on the Herbal Medicine life span when the herbal medicines will be deducted two weeks before reaching the Hub warehouse. Eventually, the products shipped by the hub warehouse to the zone B warehouse would have different expiry dates and products life spans.
