Applications and Benefits of Operations Research in Manufacturing
Operation Research (OR) applications can bring benefits in many areas in Manufacturing, such as:
Cutting stock
Materials such as paper and textiles are often produced in long rolls, the length of a truck trailer for instance. These long rolls are referred to as raws. These raws are subsequently cut into smaller portions called finals, with their sizes specified by customers. A raw can be sliced all the way through so that the diameter of each final has the same diameter as the original raw. This is usually what happens when rolls of paper are cut. Assume that a production scheduler has a list which specifies the required number of each final size. He must then develop a production schedule detailing the number of rolls and how they should be cut to meet demand. An OR application can help the scheduler to minimize the total number of rolls required to make the finals.
Liquor production planning and liquidation
The liquidation system covers the production, storage and liquidation of several kinds of whisky. Depending on the age and properties of a barrel in the warehouse its content can be used to produce a certain brand of whisky. Given the current contents of the whisky warehouse as well as a long term demand scenario the system determines a cost optimal production plan. By introducing penalties in the model, the end-user is able to identify demand shortages and production schedules that slightly violate certain quality conditions.
Transport scheduling in breweries
The transport scheduling system for breweries allows end-users to interactively steer the flow of products through all phases of the brewery process from hops to bottled beer. The application can be used either in an automatic mode, in which the flow of products is totally determined by the system, or it can be used in a manual mode where the user can set or alter this flow using a Gantt chart. The system can also be used in a simulation mode to evaluate the response of the entire brewery to varying demands over a longer period of time.
