Let D represent an operation, such as differentiation, performed on a function, and let D + εP represent a new operation differing slightly from the first, in which ε represents a small constant.
For example (p=2,) ({V}_{1}(2)) is the selected machine ({M}_{4}) for the operation ({O}_{1,2}.) The second part OS is a vector ({V}_{2}) having the same length of ({V}_{1},) where each index represents an operation ({O}_{i,j}) according to the predefined operations of the job set, see Fig. 3b.
However, the wide learning arrow represents an operation on the functional relationships (i.e. changing the weights in the lens).
Therefore, a stochastic mathematical model representing an optimal operation of energy hub is based on the objective function of minimization of energy costs (including electricity and gas).
∆ represents a delay of 1 unit, + represents an addition operation, and X represents a multiplication operation.
This has been extended to graph models with a number of variants such as the directed acyclic graphs (DAG) [19 21] where each node represents an atomic operation, and edges represent data dependencies.
Equations were presented in the form "a * b = c ", where a and b represented single digits from 1 to 9, * represented an arithmetic operation (×, +, -, or ÷), and c represented the solution.
Granulation represents a significant operation within the particle processing industry.
OP i w [DE] represents a write operation of NST; meaning that NST writes (updates) a data entity, DE, to a NoSQL database.
OP i r [DE] represents a read operation of NST; meaning that NST reads a data entity, DE, from a NoSQL database.
