Group size is a key factor in collaborative software development and many other cybernetic applications where task assignments are important. While methods exist to estimate its value for proprietary projects, little is known about how group size affects distributed and decentralized cybernetic applications and in particular open source software (OSS) development. This paper presents a novel approach...
E-business based maintenance, repair and overhaul (E-MRO) is a new MRO service mode. Although in real world there are a number of E-MRO prototype systems, few comprehensive studies have been conducted on this topic. Motivated by the challenges of making optimal E-MRO service planning, simultaneously considering the capacity constraints of MRO service providers and the maintenance constraints of equipment...
2D articulated human pose tracking in monocular image sequences remains an extremely challenging task due to background cluttering, variation in body appearance, occlusion and imaging conditions. Most of the current approaches only deal with simple appearance and or connected body part dependencies, especially the tree- structured priors assumed over body part connections. Such prior excludes...
This paper presents a robust and fully-automatic human motion tracking system without motion priors information using a camera in a fixed location. Bottom-up estimation approaches have recently been applied to such tasks with some success. However, the performance of these approaches is limited by the difficulty of building an effective appearance model. In particular, the appearance model must be...
There are some problems in rescue scheduling for major hazards with resource scheduling algorithm, in which time and resource are limited. In this paper, on the basis of the situation above, we present a new fire resource scheduling model on the ground of major hazards, where time limitation of major hazards and actual situation of fire resource can be taken into account on all sides. Thus, in line...
To realize the coordination between controlling the environmental risk caused by railway dangerous goods station (RDGS) and improving the efficiency of the whole dangerous goods transportation system, a bi-level programming model for optimizing the distribution of existing RDGSs is constructed concentrating on such two sub-problems as adjusting the location of existing RDGSs and adjusting their business...
Based on the single column partial differential equation model for the industry chromatographic separation, the mathematical model of the Simulated Moving Bed chromatographic separation process is established from the flow and mass conservation relations of the SMB process. Method of line is used for the numeric model computations. Simulation results show that compared with the true moving bed model,...
Considered the randomicity of Earthquake, a method of calculating seismic reliability of high voltage breaker was established in the paper. Considered Stochastic Earthquake Model, random seismic response spectrums of structures were gained, seismic response and reliability of high voltage breaker was analyzed used FOSM. The reliability and failure probability of the breaker under different site conditions...
The relative risk scale of bank financing products are extended nowadays, and lots of uncertain factors affects the evaluation process. In order to solve these problems, analytical network process (ANP) was utilized to estimate the risk possibility. Risk factors index system of bank financing products were built firstly. ANP considered all kinds of risk factors as well as influence among them. The...
In Data envelopment analysis (DEA), the best performers are called DEA efficient and the efficiency score of a DEA efficient unit is denoted by unity. Ranking DEA efficient units is an interesting subject. This paper proposed a super-efficiency DEA model based on slack-based measure to evaluate engineering camouflage projects. A slack-based measure of DEA model was introduced, and then it was extended...
