The 48V hybrid system has mostly adopted parallel hybrid system architecture. In the parallel hybrid system, various architecture can be derived depending on the location of the motor. In this paper, we explored a hybrid system architecture considering one or two motors and 48V electric supercharger and derived the optimal architecture by comparing the performance of each architecture. Performance of the hybrid system is mostly evaluated as fuel economy. However, since the hybrid system has increasingly been applied to various types of vehicles with different purpose of the operation, another performance index for evaluating a hybrid system is needed. Therefore, in this paper, we introduced an additional performance index to evaluate the hybrid electric drive system and used it to derive the optimal architecture of the hybrid electric drive system. We used Dynamic programming (DP) to evaluate each architecture and DP simulation was performed in the Matlab environment.

This article describes a collaboration methodology for virtual organizations where the processes can be automatically executed using a hybrid web service, grid or cloud resources. Typically, the process of deriving executable workflows from process models is cumbersome and can be automated only in part or specific to a particular distributed system. The approach introduced in this paper, exemplified by the construction industry field, integrates existing technology within a process-centric framework. The solution on the basis of a hybrid system architecture in conjunction with semantic methods for consistency saving and the framework for modeling VO processes and their automated transformation and execution are discussed in detail.

This paper deals with the modeling of an extended quartet multiprocessor kernel used for the evaluation of the Hermes system. Hermes is a multiprocessor hybrid system architecture used as a machine vision system. The functionality of Hermes requires an asynchronous information flow upwards and downwards, where "orders"(in a form of code and data) go down and "abstracted" or processed picture information goes up along the system's hierarchy. Moreover, the overall functional behavior of the Hermes system can be considered as an extended quartet kernel in an abstracted manner. The extended quartet kernel studied here presents either a memory-to-memory (M-M) or a bus-to-bus (B-B) connectivity. The evaluation of these two kernel's configurations (M-M, B-B) defines that the structural design of the Hermes system will be based on the M-M scheme. When failures occur on the quartet kernel, however, the M-M scheme will be converted into a B-B one by using a failure recovery procedure. The evaluation of the quartet kernel configurations is based on a probabilistic model. Failures and recovery procedures on the quartet kernel are discussed and the performance evaluation of the kernel (under failures) is also provided.
