Logic modeling and mathematical model can aid system analysts, system developers and programmers to
construct a system during a system development process. Logic modeling and mathematical model are the
techniques used in the system analysis phase. In the midst of the most common logic modeling, are decision
tables and structured English. These techniques help the person in charge to develop a system through
illustrations in order to give better understanding and for solving a problem specification. In this article, we
briefly describe on decision tables, structured English and mathematical model. The article aims to explain
the use of decision tables, structured English and mathematical model for the development of a tree species
selection prototype for Malaysian forest plantation. The algorithms related to the analysis of the systems
prototype were also presented in this article. Overall, the techniques are capable of supporting the data
acquisition and presentation from the context of the given problem specification
