NEGOPLAN is a prototype expert system shell for negotiation support and strategic decision support. If uses rule-based formalism for problem representation and modification, and a three-valued valuation function which gives the user strong control over the solution procedure. In this paper, extensions and modification of NEGOPLAN are discussed. Satisficing solutions can be obtained by applying a procedure which uses bounds and conditional bounds. The flexibility of a decision alternative reflects its ability to remain feasible when the environment changes. Two fact ranking methods are proposed to enable the choice of alternatives with a required flexibility. Preferences not accounted for by flexibility may be described by weighed ranks.
