Ortheogonal table, which has wide applications in experimental design, codingtheory and computer security is an importan sort of array structres. People usuallyuse the pure mathematical approaches to construct orthogonal tables. This paper weuse the quasi-physical and quasi-sociological methods to solve the problem ofconstructing orthogonal tables.The quasi-physical and quasi-sociological methods for problem-solving is a newapproach to solve problems including NP-completed and other pure mathematicalproblems. As far as the quasi-physical method is concerned, it is a way that peopleactively turn to naturt for wisdom to solving problem. In other words, it works insuch a way that to find natural phenomena which are equivalent to the originalmathematical problem in the physical world and then observe the evolution of themotion of matter in it so as to be inspired to obtain a formalistic algorithm forsolving the mathematical problem. The quasi-sociological method, however, islearning from human beings and their rich social experiences for wisdom to solvingproblem. The quasi-physical method makes the original problem an optimizationproblem in mathematics. There is often the possibility of going to a local minimum of object function when we solve the optimization problem mathematically. As forhow to jump out of the trap of local minimum so that the calculation can head for aregion with better prospects, the quasi-physical method is helpless. However, thequasi-sociological method can give us good strategies for jumping out of a trap oflocal minimum with the help of human beings' behavior and experiences.
