Abstract: The concept of using multicriteria analysis and mathematical programming for the systematic and structural assessment and support of decisions and actions of bodies and stakeholders at various levels of management in the recently deregulated Greek gas market is studied in the current paper. Appropriate multicriteria analysis and mathematical programming models are designed and incorporated in all three levels (i.e., strategic, managerial and operational) of gas market management. An important finding of this work is the outcome that operational research methodologies accurately integrate all factors involved that influence gas market decisions. The added value results from the existence of appropriate interfaces, between models of adjacent managerial levels to achieve optimum alignment of intra-level management actions and operations, in the gas market management chain.

Keywords: liberalised natural gas market; decision support; multicriteria analysis; mathematical programming.
