Despite the mathematical properties and algorithmic features of an interactive method, that method's success usually lies in the kind of information it requires from the decision maker. In some cases, this information constrains the decision maker. If she does not find it easy and comfortable to...

This paper introduces a new class of non-convex vector functions strictly larger than that of P-quasiconvexity, with P⊆ [InlineMediaObject not available: see fulltext.]<Superscript> m </Superscript> being the underlying ordering cone, called semistrictly ( [InlineMediaObject not available: see fulltext.]<Superscript> m </Superscript>\ −int...</superscript></superscript>

This study analyzes the economic effects of environmental concerns in forest management in the Swedish mountain region. The environmental concerns include the amount of deadwood, the area of broad-leaved forest, and the area of old growth forest. The analyses are performed by formulating a fuzzy...

This study investigates the tradeoffs among different uses of forests in the Swedish mountain region, where several interest groups use the forests for different and conflicting objectives. The tradeoffs information can help the involved interest groups to reach a rational compromise on the...

The paper deals with a stability of multiobjective stochastic programming problems in which objective functions are in the form of mathematical expectation of functions depending on a random element and a constraints set is deterministic. The stability is investigated with respect to a...
