Example: Modeling Resource Requirements for Reliability Elements

Sometimes desired actions can be constrained by Resource Something that has a limited supply (e.g., spare parts, fuel, skilled personnel, money) and is required in order for elements of the modeled system to carry out certain actions. availability. For example, if a system component failed, its repair might not be possible until a mechanic and an appropriate spare part were available. In this case, the pool of mechanics and the stock of spare parts would be considered as Resources. Some resources, such as spare parts, are consumed when they are used. Others, such as mechanics, are only borrowed, and become available again once they are no longer required.

One of the advanced features in GoldSim is the ability to create and interact with Resources. Within GoldSim, a Resource is defined as something that has a limited supply (e.g., spare parts, fuel, skilled personnel, money) and is required in order for elements of the modeled system to carry out certain actions.

The model file ReliabilityResources.gsm, found in the Reliability Examples folder in your GoldSim directory (accessed by selecting File | Open Example... from the main menu), demonstrates the use of Resources when within Reliability elements. In particular, this model creates two (global) Resources Stores: Spares and Technician. The Stores start with 5 Spares and 1 Technician.

Three components are simulated, and each one has a failure mode that is automatically repaired. In each case, however, the repair uses 1 Spare and borrows 1 Technician.

Moreover, the model includes logic for ordering new Spares.
