One of the main objectives of the pharmaceutical industry is to provide products that are safe, of high quality and effective. Additionally to that, most often companies would like to reduce costs. To achieve this, they must implement Good Manufacturing Practices (GMP). Pharmaceutical production planning and scheduling is a very complex task, as not only resources, materials and equipment have to be taken into account, but also regulatory deadlines and legal requirements. In addition, there are many constraints such as limited availability of sub-products, skilled personnel or equipment. This paper presents a review of production planning and scheduling methods in the pharmaceutical industry with its preliminary analysis, which will form the basis for future work in this area.
