Product theory draws lessons from data envelopment analysis and analytic hierarchy process, classifies and layers all kinds of uncertain factors under decision objectives, forms multiple criteria according to each criterion, establishes an optimization matrix, that is, the decision matrix of long-short game, obtains the mixed optimal solution, obtains the weight coefficient of the mixed optimal solution under each criterion, and re-plans. Finally, the optimal decision scheme is formed by integrating the results.
The analysis method of product theory is applicable to the market transactions of stocks, futures, foreign exchange, stock indexes, gold and silver and financial derivatives. Logarithmic product theory combines theory with practice and is a complete and comprehensive "system theory" in the field of financial transactions.
