A simulation approach is presented for planning and scheduling a flow of complex jobs for job shop like production systems. Machines may have their own specific restrictions and properties such as relative production speed, set up characteristics and scheduling rules. A production job consists of a set of tasks represented by a directed activity network in which an activity is defined as a sing...

An efficient method of parallel fault simulation for combinational circuits is proposed. The method is based on structurally synthesized BDDs (SSBDD) which allow to represent gate level circuits at higher macro level where macros represent subnetworks of gates. Converting the gate-level circuits to the macrolevel is accompanied with corresponding fault collapsing. A parallel fault analysis algo...

The purpose of the paper was to address the timeliness of the signaller's intervention in the Ladbroke Grove rail incident in the UK, as well as to consider the utility of human performance time modelling more generally. Human performance response time modelling is a critical area for Human Factors and Ergonomics research. This research applied two approaches to the same problem to see if they ...

In this paper we present an efficient algorithm for compile-time scheduling and clustering of parallel programs onto parallel processing systems with distributed memory, which is called The Dynamic Critical Path Scheduling DCPS. The DCPS is superior to several other algorithms from the literature in terms of computational complexity, processors consumption and solution quality. DCPS has a time ...

Recently, an approach using the discrete event paradigm for the simulation of continuous systems has been developed. This approach is based on the use of piecewise-linear approximations for the representation of continuous, time-varying quantities. The focus of this paper is to show how this new technique can be implemented on a multiprocessor. Our hypothesis is that the Time Warp algorithm is ...

Hubs are critical elements of transportation networks. Location of hubs and allocation of demands to them are of high importance in the network design. The most important purpose of these models is to minimize the cost, but path reliability is also another important factor which can influence the location of hubs. In this paper, we propose a P-center hub location model with full interconnection...
