This paper summarizes three failure models of pre-stressed pipe pile under horizontal load. From the view of reliability, the author has established corresponding performance functions of two failure models. And on the basis of functions, various factors affecting the reliability of pile's bearing capacity are analyzed. After calculation of four field examples, the results reveal that the thickness...
Poverty is essentially resulted not from low income but weak wealth-building ability. From capability poverty perspective, this paper to studies the essence and measures of anti-poverty oriented standard in two aspects: the basic subsistence capacity and potential development capacity, and analyzes the differences between the ability-building orientation and income -raising orientation standards ...
The main objective of power system planning is maintaining an adequate level of reliability. The reliability concept has two characteristics: resource adequacy and operational reliability. Traditionally these two characteristics are addressed separately through a sequence of probabilistic and deterministic analyses without a systematic view. This paper presents a resource planning problem that explicitly...
This study first gave a definition about the authorizing quality of scientific and technological project, and then built the evaluation index system, proposed a new model called “hierarchical analysis- entropy-ideal solution sort” to evaluate the authorizing quality of scientific and technological projects.
This paper establishes a math model of cost-benefit data envelopment analysis based on service capacity evaluation issue of E-commerce system, and presents it as the E-commerce capability evaluation method. This evaluation method based on the basic thinking of DEA. Finally, it verifies the validity and practicality of this model through taking the actual operation of e-commerce service platform as...
A study was carried out to investigate customer satisfaction level towards the public transportation services provided by Consortium Express Bus Company. 200 respondents consisting of 65 men and 135 women participated in the study survey. The survey was conducted in three bus stations in Kuala Lumpur and Selangor areas, namely Pudu Bus Station, Kajang Bus Station, and Putra Bus Station. Importance-Performance...
This paper presents a novel method for evaluating facilities in regard to their designed intelligence. Facilities intelligence is defined as the designed capacity of a facility to acquire and process data and information to perform its adaptability to life-cycle circumstance changes in terms of people's requirements of well-being and energy efficiency. This definition is then formulated to quantify...
This paper presents the application of fuzzy clustering technique on large load data to greatly reduce calculations in reliability evaluation of restructured power systems. The method involves: first grouping a large load data into few clusters, secondly calculating partial membership value of each load point in each cluster, thirdly calculating reliability indices for each cluster and finally, expressing...
This paper proposes a new method for the incorporation of the generation unit and transmission line unavailability in the solution of the unit commitment problem. The above parameters are taken into account in order to assess the required spinning reserve capacity at each hour of the dispatch period, so as to maintain an acceptable reliability level. The unit commitment problem is solved by a Genetic...
Conventional reliability analysis rely on the probability model, which is often inappropriate for handling complex systems due to the lack of sufficient probabilistic information. For large complex systems made up of many components, the uncertainty of each individual parameter amplifies the uncertainty of the total system reliability. To overcome this problem, the concept of fuzzy approach has been...
