document: Dynamic multi-objective heating optimization We develop a multicriteria approach to the problem of space heating under a time varying price of electricity . In our dynamic goal programming model the goals are ideal temperature intervals and the other criteria are the costs and energy consumption . We discuss the modelling requirements in multicriteria problems with a dynamic structure and present a new relaxation method combining the traditional epsilon - constraint and goal programming -LRB- GP -RRB- methods . The multi-objective heating optimization -LRB- MOHO -RRB- application in a spreadsheet environment with numerical examples is described
