Considering a core is an empty set , in view of the application scope of the core and its limit , this paper develops one multi - objective programming model for the cost allocation problem of n - person cooperation game , and then presents two - phase approach for solving the cost allocation problem 摘要考慮核心是空集的情況,針對核心法的適用范圍和局限性,建立了一種多人合作費用分攤的多目標規劃模型,給出了求解費用分攤方案的兩階段算法。
The representation theories of mp - filter which is created by an non - empty set of a implication algebra on a partial ordered set with condition ( c ) are obtained at first . and it ' s proved that the set which contains all mp - filters of a implication algebra x , denoted by mf ( x ) = { f x f is a filter of x } , is a distributive lattice and a complete lattice also in the view of the concept of mp - filter . then the fuzzy filter of a implication algebra is discussed , and the relations between mp - filter and fuzzy filter are obtained 借助于mp -濾子的概念,得到了偏序集上具有條件( c )的蘊涵代數中由非空集合所生成mp濾子的表示定理,證明了由其上所有mp -濾子組成的集合mf ( x )是一個完備的分配格;得到了蘊涵代數中fuzzy濾子與mp濾子的關系,給出了fuzzy濾子成為fuzzy素濾子的若干刻畫;并利用mp -濾子和fuzzy濾子,刻畫了一類偏序集上蘊涵代數的結構。
