In this study, we develop a conceptual model to illuminate how firms can better compete through service basing on a process view. In accordance with the thought of organizational ambidexterity, we firstly suggest that the efficiency and flexibility in the operation of service process are equally important for organizations desiring to achieve a superior service performance. Additionally, consid...

abstract regarding temporal variation of rivers discharge and demands, for suitable use of dam reservoirs stored water, application of operation rule curves is necessary. operation rules are expressed with rule curves. application of yield model is one of the methods of operation curve preparation, which correlates reservoir operation with reservoir storage volume in first period. in this study...

quality of service (qos) is an important issue in the design and management of web service composition. qos in web services consists of various non-functional factors, such as execution cost, execution time, availability, successful execution rate, and security. in recent years, the number of available web services has proliferated, and then offered the same services increasingly. the same web ...

service oriented enterprises (soes) are subject to constant change and variation. in this paper, the changes are considered from an economic perspective based on service culture notion. once a change is implemented, the costs of some member services may increase, whereas the costs of some other services may reduce. we construct a game theoretic model trying to capture the possible conflicting i...

The touted goal that drives the field of Active Networks lies in the concept of dynamic service provisioning. In this, when an Active Node is presented with a request for a service, it will be able to either provide the service: (i) immediately – if the requested service is available locally; or (ii) after an initial delay – caused due to discovery, deployment and instantiation of the service d...

We present a state reduction method that effectively reduces a two-dimensional Markov model to a one-dimensional Markov model for the performance analysis of a class of concurrent data structure maintenance policies. The reduced model allows the derivation of a closed form expression for the average service time per operation and facilitates the identification of priority allocation functions u...

In this paper we i.ntroduce R, a distributed public key management service for open networks. f’l offers interfaces by which clients can register, retrieve, and revoke public keys, and escrow, use (to decrypt messages), and recover private keys, all of which can be subjected to access control policy. R is built using multiple servers in a way that ensures its correct operation despite the malic...

Throughput capacity is the production capacity of port enterprise under constant exotic environment, and plays a significant role in production control. According to the analysis on influencing factors of throughput capacity and characters of operation system, this paper proposes a simulation model of container terminal operation system based on port service level. By changing input parameters,...

In wireless sensor networks, a critical system service is the localization service that determines the locations of geographically distributed sensor nodes. The raw data used by this service are the distance measurements between neighboring nodes and the position knowledge of anchor nodes. However, these raw data may contain outliers that strongly deviates from their true values, which include ...
