We first take the sample average approximation method to deal with the expectation and gain an approximation problem, further the rationality is given. When the underlying function is Lipschitz continuous, we acquire a projection and contraction algorithm to solve the approximation problem. In the end, the method is applied to some numerical experiments and the effectiveness of the algorithm is verified.展开更多

The study concentrates on analysis of the relationship management on a psychological con- tract perspective, shows that constructing good psychological contract is useful to promote mutual trust, reduce the transaction cost caused by incompleteness of formal contract, avoid the risk of supplier management between the main manufacturer and suppliers of the large aircraft project. And with further understanding of the dynamic contracting process as well as formation framework of psychological contract between the main manufacturer and suppliers, we can better understand the relationship black-box and provide a new perspective for the study of the relationship management, then given some constructive suggestions to supplier relationship management.展开更多

Among them, the design-oriented EPC project general contracting has been vigorously promoted by the national policy due to its technical advantages and resource advantages. This paper analyzes the characteristics of the general contracting mode and design-led EPC municipal projects, the existing problems in cost management, and the cost control and management measures at each stage.展开更多

Let X and Y be Banach spaces and T1 : XγY→ X and T2 : XγY → Y be two operators which satisfy weak (k, k') contractive type condition. Using T1 and T2, we construct an operator T on X γ Y and show that T has a unique fixed point in a closed and bounded subset of X γY. We derive an iteration scheme converging to this unique fixed point of T. Conversely, using a weakly contractive mapping T, we construct a pair of mappings (T1, T2) satisfying weak (k, k') contractive type condition on X γ Y and from this pair, we also obtain two self mappings S1 and S2 on X and Y respectively with unique fixed points.展开更多

The four principal risk analysis groups include: 1) transparency in the light of corporate governance 2) IT security 3) contract management automation and 4) legality. The AHP assists both decision-makers and stakeholders alike in the evaluation process essential for identifying potential technological constraints posed within a permissioned blockchain environment using peer-to-peer format in the absence of digital currency. Based upon critical assessment, the AHP methodology enables pairwise comparisons among different features and consequently increases the knowledge regarding these attributes in light of the software’s risk assessment.展开更多

Due to the fact that non-expansive mapping is only O-strictly pseudo-contractive, the main result obtained in this paper extends the corresponding main result of Nakajo-Takahashi from non-expansive mapping to k-strictly pseudo-contractive one, where k∈ [0,1).展开更多
