New Sequential Fuzzy Linear Programming Method Using "m-operator" and its Application to a Closed Environmental Life Support System

Abstract

There are many large systems composed of several subsystems such as a chemical plant and an iron-manufacturing plant. It is common to formulate these systems by the use of a mathematical programming because an optimal operation of these systems forms a multivariate problem with multiple constraints and purposes. Introducing the new method, m-operator, into a sequential fuzzy linear programming problem and applying it to the control problem of a closed ecological life support system (CELSS) as an example to be solve, we show usefulness of this method.
