This paper focuses on the design, development and implementation of new Par
eto efficiency detection and restoration techniques for integer goal progra
mming. The design of the algorithms and their implementation issues within
(an otherwise continuous) goal programming system are detailed. The differe
nces between continuous and integer goal programming regarding Pareto effic
iency detection and restoration analysis are described. The integer Pareto
efficiency techniques have been applied to a selection of problems from dif
ferent industrial contexts in order to assess their computational performan
ce. Finally, Pareto restoration and detection techniques are applied to an
integer goal programming problem to illustrate the methodology. (C) 1999 El
