implementation
the use of model results
implicit enumeration
a method for solving integer programming problems in which obviously infeasible solutions are eliminated and the remaining solutions are systematically evaluated to see which one is best
independent demand
final product demanded by an external customer
independent events
events for which the probability of occurrence of one event does not affect the probability of occurrence of the other events

inequality
a mathematical relationship containing a or sign
infeasible problem
a linear programming problem with no feasible solution area and thus no solution
instantaneous receipt
the assumption that once inventory level reaches zero, an order is received after the passage of an infinitely small amount of time
integer programming
a form of linear programming that generates only integer solution values for the model variables
inventory
