Location factors related to the transportation of materials into and from a factory. The principle of substitution is a fundamental basis of the cost approach to machinery valuation. But if you are just deriving classes without using interfaces, this problem can occur. Model developed by Alfred Weber according to which the location of manufacturing establishments is determined by the minimization three critical expenses: labor, transportation, and agglomeration. I find this principle the most confusing because the whole idea of polymorphism and inheritance is to derive from base classes, but override the methods of the base class with a different implementation. The premise is that any type derived from a base class should be able to be used in place of the base class. Which means, Derived types must be completely substitutable for their base types More formally, the Liskov substitution principle (LSP) is a particular. The Liskov Substitution Principle (LS) deals with interfaces.
