INVENTORY MANAGEMENT FOR PHARMACEUTICAL INDUSTRY
BrazilĆ¢ĀĀs pharmaceutical market, the second largest in the emerging world, is growing at a 28 percent compounded annual rate. In 2010, the value of the prescription drugs sold to BrazilĆ¢ĀĀs middle class was $8 billion, mostly for unpatented medications. According to McKinsey report1, the middle class prefers to rely on public health services, whose physicians prescribe only generic drugs. Moreover, it reported that cost-conscious middle-class patients ask pharmacists to switch their medications to less expensive generics even when physicians prescribe branded drugs.
As a result, global pharmaceutical companies have concluded that they must focus on low-cost strategy for generics and branded generics. Nine of the largest local pharmaceutical films in Brazil (Ache, Biolab, Cristalia, Libbs, EMS, BioNovis, Hebron, Eurofarma and Orygen) have invested BRL538 million (USD174.3 million) during the first five months of 2015, focusing mainly on the production of biosimilars and generics2.

Campinas is a city in State of Sao Paulo, Brazil. To the north are a series of coastal towns that are growing very quickly. In 1998, PharmaDist Co.-a pharmaceutical wholesaler serving nine largest local pharmaceutical producers) opened a distribution center in Campinas to supply pharmaceuticals and related products to retail pharmacies, hospitals, dispensing doctors and a few other outlets. In the past, deliveries of pharmaceuticals in this remote area had been made directly by manufacturers, but the growing population had encouraged wholesalers to open. Now there is a mature industry giving an efficient delivery service from centralized warehouses.
As more pharmaceutical wholesalers arrived the market has become increasingly competitive. PharmaDist is one of the main wholesaler companies in the area. It is now classified as a medium-sized private company which is run efficiently and gives a good service to customers. The three main activities of PharmaDist are:
Ć¢Ā order taking and processing
Ć¢Ā stock holding and control
Ć¢Ā delivery to customers.

To ensure his companyĆ¢ĀĀs continuing success, Orlando Marcelo, the CEO is always looking for improved performance. A short while ago he was concerned that the cost of deliveries to customers was rising. The distribution system had been reviewed occasionally as the company grew, but it was essentially designed for a much smaller operation.
Orlando hired a management consultant to give advice on improving the transport operations. The consultant did some work which suggested areas for improvement, and his final report suggested that the company look at its stock holding policies. Orlando looked at the stock control system, which was based on standard software provided by SOFT seven years earlier. This had been updated and expanded twice, and still seemed to work quite well. Unfortunately, a close examination showed that stock levels had actually been drifting upwards for some time. The purchasing department explained that the company was successful because it had a reputation for reliability and service. A customer could e-mail, fax or telephone an order and delivery would be guaranteed during the next working day. Unfortunately PharmaDist had occasionally run out of stock and had let down customers (their own lead time from manufacturers averaged about a week). To ensure 97% service level, the purchasing department had adopted a policy of keeping two weeksĆ¢ĀĀ demand in reserve stock, but for some reason this seemed to be drifting up to three weeksĆ¢ĀĀ demand. The same ordering procedure was used for all items. This was based on the purchasing departmentĆ¢ĀĀs view that the most important factor was average demand over the past five weeks. This value was used as a forecast of future demand. Then a reorder level was set as:
Reorder level = Forecast ĆĀ (lead time + safety stock) ĆĀ Factor
where Factor is a variable between 1 and 2 to give a subjective view of the itemĆ¢ĀĀs importance and the supplierĆ¢ĀĀs reliability. Order quantities are really set by the number of staff in the purchasing department. Three people work in the department, each processing up to sixty orders a day. In 200 working days a year they can process 36,000 orders. As there were 4000 items in stock, each item can have an average of 9 orders a year. To add another element of safety, each order was made big enough to last about eight weeks. The system was largely automated, and nobody really checked its performance. Items were usually in stock when they were needed, so managers did not look at the details of the operations. Unit costs varied between one dollar and several hundred dollars, and no one had calculated cost of stock holding or ordering.
