The increasing tendency of container vessel enlargement and the container transportation growth, make people pay more and more attention to the efficiency of the container terminal berths. In order to improve the berth efficiency, this paper focuses on continuous berth allocation problem. Firstly, a penalty cost function is suggested to comprehensively consider the delay of vessel leaving time and...
Ensuring process execution reliability and success is crucial for business process management. A mechanism is required to link high-level requirements to transaction management and utilize runtime information to remedy occurred problems. However, workflow transaction models have a gap with high-level requirements, and their limited forward recovery mechanisms lead to lots of unnecessary aborts. This...
With rapid development of very large integrated circuit, flip chip bonder (FCB) becomes an important microelectronics package device. Bonding head in FCB is one of the most important functional components used to deal with the process of chip bonding and is of the highest motion precision. Since both resonance and additional vibration in bonding head significantly affect the working precision, therefore,...
Time is a crucial factor in business process management. Business processes fail to accomplish when temporal inconsistency occurs between participants. Traditional temporal consistency verification methods only focus on available temporal information of web services, and the temporal constraint, which requires that the next service must be available after all previous services accomplish, is too strong...
With the development and wide application of the computing technology, performance testing becomes more and more important. Real simulation of the user behavior becomes a concern of the performance testing. The paper introduces the potential model to establish the model of the visit amount which can be used in the performance testing. Firstly, the paper introduces the role of HBase in the search engine...
The development and wide application of the internet technology produces a large amount of data, in order to storage and manage these massive data, NoSQL database technology comes into beings and develops rapidly, many manufacturers have introduced many different NoSQL storage solutions. In this context, the paper carries out the work about the testing method of the performance of NoSQL database....
Dynamic substitution of conversational services during the execution of service orchestrations is a challenging issue in Service-Oriented Architecture. For a conversational service and its candidate substitute service, there may exist mismatches at interface level as well as protocol level. To make the service substitution consistent, it is essential to implement adaptation to overcome both types...
Scalability is an important metric which is used to evaluate the scalability of the cluster system. Although, there have been a lot of scalability metrics, the research of scalability of the cluster system is very few. Common scalability evaluation methods are usually used to analyze the scalability of the algorithm. They can also be used to analyze the scalability of the cluster. These methods are...
The information contained in the successful test case has been fully tapped by metamorphic testing which can effectively solve the oracle problem of software testing. One of the key factors affecting the results of the metamorphic testing is the generation of test cases. In this paper, we propose a criterion called ECCEM (Equivalence-Class Coverage for Every Metamorphic Relation), which covers the...
Phenomenon of bottleneck shiftiness was studied in this paper, including bottleneck shiftiness causes, its representation and solutions. In this study, bottleneck shiftiness causes were mainly divided in two kinds based on its inner qualities, one kind was demand fluctuation and the other kind was facility exception. In order to keep relative stability of the production system and reduce complexity...
With globalization of the world economy, supply chain management has been emphasized as one of the most important management strategies. And, supply chain profit allocation is a significant part in supply chain management, which keeps the supply chain running efficiently and steadily. This paper, comprehensively discusses the supply chain profit allocation issue, based on cooperation game theory....
Survivability is crucial for computer systems that support critical infrastructures of our society. For those in paradigm of SOA where the computing settings are intrinsically open, traditional survivability model and safeguard mechanisms are no longer applicable. To rise to the challenge, we propose a formal definition and a corresponding framework to evaluate the survivability of SOA systems. We...
