The 窶廴odel窶 menu is available only when you view or edit a model file. In this menu you will find all the commands you need to create the objects representing the variables in your risk model.
New node
In DynRisk you have five different menu items that can be used to create new nodes. Each different item corresponds to certain algorithm and operator properties of the node.
All other properties will be taken from the default settings specified in the 窶廸odes and events窶 preferences.
In particular, if you have chosen to include stochastic values as default, the nodes you create, will be stochastic. On the other hand if you have chosen not to include stochastic values as default, the nodes you create, will be deterministic. In any case you can reverse the chosen option by holding down the 窶彜hift key窶 while you choose a menu item. That is, if nodes are stochastic by default, you create a deterministic node by pressing the 窶彜hift key窶. Similarly, if nodes are deterministic by default, you create a stochastic node by pressing the 窶彜hift key窶.
Except for independent nodes, a new deterministic node will be created with 窶廨lobal only窶 as 窶廣lgorithm窶, while a new stochastic node will be created with 窶彜ingle窶 as 窶廣lgorithm窶.
All the properties can of course be changed later on if necessary.
Independent
An independent node has 窶廰ocal only窶 as 窶廣lgorithm窶 and no operators.
Sum
A sum node has 窶彜um窶 as 窶廾perator 1窶. If the node is deterministic, its 窶廣lgorithm窶 will be 窶廨lobal only窶. If the node is stochastic, its 窶廣lgorithm窶 will be 窶彜ingle窶.
Product
A product node has 窶弃roduct窶 as 窶廾perator 1窶. If the node is deterministic, its 窶廣lgorithm窶 will be 窶廨lobal only窶. If the node is stochastic, its 窶廣lgorithm窶 will be 窶彜ingle窶.
Maximum
A maximum node has 窶廴ax窶 as 窶廾perator 1窶. If the node is deterministic, its 窶廣lgorithm窶 will be 窶廨lobal only窶. If the node is stochastic, its 窶廣lgorithm窶 will be 窶彜ingle窶.
Minimum
A minimum node has 窶廴in窶 as 窶廾perator 1窶. If the node is deterministic, its 窶廣lgorithm窶 will be 窶廨lobal only窶. If the node is stochastic, its 窶廣lgorithm窶 will be 窶彜ingle窶.
