This paper is to promote investigation into the nuclear rocket engine (NRE) propulsion option that is considered as a key technology for manned Mars exploration. Russian NRE developed since the 1950s in the former Soviet Union to a full-scale prototype by the 1990s is viewed as advantageous and the ...

How to deal with the collaboration between task decomposition and task scheduling is the key problem of the integrated manufacturing system for complex products. With the development of manufacturing technology, we can probe a new way to solve this problem. Firstly, a new method for task granularity...

Electromagnetic detection satellite (EDS) is a type of Earth observation satellite (EOS). Satellites observation and data down-link scheduling plays a significant role in improving the efficiency of satellite observation systems. However, the current works mainly focus on the scheduling of imaging s...

There has been a number of algorithms designed to handle intra-query or inter-query scheduling in multiprocessor-based parallel database system. They all have the assumption that the processors are identical. But in some cases, such as shared nothing environment, this assumption would not be fully v...

This paper models the scheduling of one type of flexible transfer line as an integer programming problem. Since the integer program falls within the NP class of problems, then its complexity increases exponentially as the problem size increases, making the problem intractable even for a medium size ...
