Confidence Neutrosophic Number Linear Programming Methods Based on Probability Distributions and Their Applications in Production Planning Problems.

Publication Type:Academic Journal

Source(s):Mathematical Problems in Engineering. 8/8/2022, p1-14. 14p.

Abstract:A neutrosophic number linear programming (NN-LP) method reveals a useful tool for solving optimal production planning problems in an indeterminate environment. The optimal feasible solutions of the decision variables and the objective function in the N...

The Empirical Reality of IT Project Cost Overruns: Discovering A Power-Law Distribution.

Publication Type:Academic Journal

Source(s):Journal of Management Information Systems. 2022, Vol. 39 Issue 3, p607-639. 33p. 1 Diagram, 6 Charts, 7 Graphs.

Abstract:If managers assume a normal or near-normal distribution of Information Technology (IT) project cost overruns, as is common, and cost overruns can be shown to follow a power-law distribution, managers may be unwittingly exposing their organizations to e...

Sensitive Information Protection Model Based on Bayesian Game.

Publication Type:Academic Journal

Source(s):Computers, Materials & Continua. 2022, Vol. 73 Issue 1, p883-898. 16p.

Abstract:A game measurement model considering the attacker's knowledge background is proposed based on the Bayesian game theory aiming at striking a balance between the protection of sensitive information and the quality of service. We quantified the sensitive ...

Characterizations of Probability Distribution by Some Sequential Relative Reliability Measures: An Application of Completeness in a Hilbert Space.

Publication Type:Academic Journal

Source(s):Journal of Function Spaces. 8/10/2022, p1-10. 10p.

Abstract:In this paper, by means of the concept of completeness in functional analysis, we characterize probability distributions using several relative measures of residual life of an item at independent sequences of random times. These sequences are the order...

转向节疲劳寿命评价及其局部裂纹尺寸的概率分布.

Publication Type:Academic Journal

Source(s):Journal of Northeastern University (Natural Science). Jun2022, Vol. 43 Issue 6, p864-871. 8p.

Abstract:转向节的作用是传递和承受汽车的前部载荷,支承和驱动前轮绕主销转动,使汽车转向.针对仍处于开发阶段的某麦弗逊式转向节的疲劳失效问题,提出了一种对其台架试验结果进行评估的方法,根据转向节在系统中的实际连接情况分多工况进行了疲劳台架试验,利用Weibull分布理论结合 N○50%, N○90% 标准对转向节的失效循环次数分布进行了评价,同时推导了一种局部疲劳裂纹尺寸的概率分布预测模型,并利用实测试验数据验证了所推导预测模型的适用性. [ABSTRACT FROM AUTHOR]...
