Permutation statistics wm¯ and rlm are both arising from permutation tableaux. was introduced by Chen Zhou, which proved equally distributed with the number of unrestricted rows a tableau. While is shown Nadeau 1’s in first row In this paper, we investigate joint distribution rlm. Statistic (rlm, wm¯, rlmin, des, (321)) on Sn. Then generating function wm¯) follows. An involution constructed to ...

Focusing on the generation mechanism of random permutation solutions, this paper investigates the application of the Simulated Annealing (SA) algorithm to the combinatorial optimisation problems with permutation property. Six types of perturbation scheme for generating random permutation solutions are introduced. They are proved to satisfy the asymptotical convergence requirements. The results ...
We present a framework for the specification of distributed protocols based on a logic-based presentation of bipartite graphs. For the considered language, we define assertions that can be applied to arbitrary configurations. We apply the language to model the distributed version of the Dining Philosopher Protocol. The protocol is defined for asynchronous processes distributed over a graph with...
This paper proposes a heuristic algorithm, called list-based squeezing branch and bound algorithm, for solving a machine-fixed, machining-assembly flowshop scheduling problem to minimize makespan. The machine-fixed, machining-assembly flowshop consists of some parallel two-machine flow lines at a machining stage and one robot at an assembly stage. Since an optimal schedule for this problem is n...
Web Services for Transmitting Product Information in the Context of Business-to-Business Integration
Imagine that the product data of every online shop would be machinereadable and you could find the best product offers in an instant. Many e-business scenarios, such as price comparers, electronic markets, product search engines, and shop directories require integration of distributed heterogeneous information systems. Information extraction from heterogeneous Web sites has been a research topi...
Smaller production companies, such as job shops, are often incapable of committing significant human or capital resources for the improvement of manufacturing flow times. However, there is considerable demand in these organizations for solutions that offer improvements without the risk involved in expending these resources. This paper investigates the impact of scheduling rules and reorganizati...
