Particles labelled 1 · · · n are arranged initially in increasing order. Subsequently, each pair of neighbouring particles that is currently in increasing order swaps according to a Poisson process of rate 1. We analyze the asymptotic behaviour of this process as n → ∞. We prove that the space-time trajectories of individual particles converge (when suitably scaled) to a certain family of rando...

We propose decision-oriented process modelling as a step towards human-centered process management, and demonstrate some implications of this model for the interaction between process modelling, process enactment, and process performance in a CASE environment. We also discuss the potential our approach offers for experiencebased process improvement.

Distributing process-oriented programs across a cluster of machines requires careful attention to the effects of network latency. The MPI standard, widely used for cluster computation, defines a number of collective operations: efficient, reusable algorithms for performing operations among a group of machines in the cluster. In this paper, we describe our techniques for implementing MPI communi...

In the context of the implementation of increasingly complex IT systems a solid high quality and complete requirements analysis is a must. No one will dispute this statement seriously and yet the requirements analysis process and in particular, the process-oriented analysis is an unloved stepchild in many projects. When asked about the reasons, we always encounter the same familiar suspects: no...

at first, this article explained the theoretical foundations of sadraee wisdom as a criterion for evaluation, then; it discussed the bourdieu’s intellectual system and then is criticized his approach. in discussing the theoretical foundations of authenticity of individual and society, substantial motion, human truth, knowledge, integration and development-oriented nature based on sadra’s point ...

This paper draws on the “human reliability” concept as a structure for gaining insight into the maintenance workforce assessment in a process industry. Human reliability hinges on developing the reliability of humans to a threshold that guides the maintenance workforce to execute accurate decisions within the limits of resources and time allocations. This concept offers a worthwhile point of de...

in many real world assembly line systems which the work-piece is of large size more than one worker work on the same work-piece in each station. this type of assembly line is called multi-manned assembly line (mal). in the classical multi-manned assembly line balancing problem (malbp) the objective is to minimize the manpower needed to manufacture one product unit. apart from the manpower, othe...
