AN ALGORITHM TO IDENTIFY ALL PATHS IN SCHEDULING NETWORKS

The purpose of this paper is to present an algorithm that identifies every path in scheduling networks. The algorithm finds the answer by simulating the way we solve the problem by hand. The result is a list, in sequential order, of all activities involved in each path, the algorithm is divided into forward and backward passes that are repeated until all paths have been identified. Backward passes determine the existence of paths, while forward passes determine the activities involved in the paths. The algorithm has been successfully tested with 31 construction networks, and has been implemented in simulation programs used for construction scheduling and probabilistic analyses.     

企业的横向兼并投资决策——实物期权方法

应用实物期权方法分析了不确定性环境企业的横向兼并投资决策问题，将企业所拥有的兼并投资机会看作是企业所持有的看涨期权，应用期权定价理论分析了兼并期权的价值，得到了最优兼并投资决策的临界值以及不确定性下横向兼并投资决策的托宾q有修正值，在分析中考虑了横向兼并的规模经济效应与垄断效应，并分析了这两种效应对策的影响。

Specific features of the influence of hydrogen on the properties and mechanism of fracture of the metal of welded joints of steam pipelines at thermal power plants

We study the standard tensile mechanical properties of a live-steam pipeline operated for about 2 · 10⁵ h and model (repair) welded joints. As a result of the degradation of weld metal under service conditions, its strength becomes lower than that of base metal. We show that the unregulated orientation of specimens along the axis of a welded joint is the most acceptable for detecting the degradation of weld metal. Cathode polarization facilitates evaluating the state of the degraded weld metal and that of the base metal. We have also disclosed the specific features of the influence of internal (preliminary hydrogenation) and external (electrolytic hydrogenation in the course of tests) hydrogen on the properties and mechanisms of the fracture of weld metal. __________ Translated from Fizyko-Khimichna Mekhanika Materialiv, Vol. 42, No. 4, pp. 26–35, July–August, 2006.
