关于《共产党宣言》“两个必然”论断的再思考

本文从资本主义生产方式生长形成、发展成熟、衰落消亡的角度,重新考查《共产党宣言》关于“两个必然”的论断,揭示出“两个必然”的实现将是一个由“斗争期”、“合作期”、“必然期”三个相互衔接的历史阶段构成的渐进过程。

关于马克思、恩格斯“两个必然”论断的再思考

资产阶级的灭亡和无产阶级的胜利是人类社会发展的总趋势。但是,“两个必然”是一个渐进的历史过程,其中要经历斗争期、合作期和必然期三个相互衔接的历史阶段。

Minimizing Tardy Jobs in a Single Machine Scheduling Problem with Fuzzy Processing Times and Due Dates

The optimality of a fuzzy logic alternative to the usual treatment of uncertainties in a scheduling system using fuzzy numbers is examined formally. Processing times and due dates are fuzzified and presented by fuzzy numbers. With introducing the necessity measure, we compare fuzzy completion times of jobs with fuzzy due dates to decide whether jobs are tardy. The object is to minimize the numbers of tardy jobs. The efficient solution method for this problem is proposed. And deterministic counterpart of this single machine scheduling problem is a special case of fuzzy version.
