How it affects the model

To indicate that the Supplier, Warehouse, Production…etc., can be used by the model. Only Available without Force Open does not necessarily mean that the minimum and maximum capacity will be considered, in other words the constraint will be conditional. If both Available and Force Open attributes are defined then the constraints must be met. For example, if the Warehouse has minimum capacity (10000) and it is only Available and not Force Open, the inbound/outbound of the warehouse can be less than the minimum capacity (e.g.:5000) and the model will be feasible. But if the Warehouse is available and force open the inbound/outbound of the warehouse can not be less than the minimum capacity or the model is infeasible. Objects with {Curly Bracket} does not need Available attribute if single elements of the group have Available attribute.
