- Scenario A combined cycle gas turbine power station requires a webbased system to manage the storage and installation of spare parts and the acquisition of new parts from the Central Storage Warehouse (the CSW). The powerstation maintains an inventory of all the parts it owns comprising: part name, description and specification. There are many copies of some parts – each part has a unique ID, known as an asset tag number. The asset tag number is used when there is damage to particular parts. The power station also keeps a catalogue of all the possible spare parts types used.Only registered maintenance engineers and team leaders are allowed to install and repair parts on the plant. Maintenance engineers and team leaders can use the parts catalogue tosearch for part types and can also search the parts inventory. Maintenance engineers work in teams, currently: electrical, mechanical and environmental. Each team has its own team lead.

Units of each item may be stored in multiple storehouses, and it is important to know precisely how many items are stored in each storehouse. In addition, TAL Distributors now want to manage information about the suppliers from which it purchases items. For each item, TAL Distributors needs to know the number and name of each supplier as well as the expected lead time for delivering each item. (Lead time is the amount of time a supplier is expected to take to deliver the item after TAL Distributors has ordered it.) Each item can have many suppliers, and each supplier can supply many items.
