PERFORMANCE MODELING OF E-PROCUREMENT WORKFLOW USING GENERALISED STOCHASTIC PETRI NET (GSPN)
This paper proposes a Generalised Stochastic Petri net (GSPN) model representing a generic e-procurement workflow process. The model displays the dynamic behaviour of the system and shows the inter relationship of process activities.

Формальное описание систем средствами Петри-объектных моделей [PDF]
The article considers the new formal methods for system's description based on object-oriented methodology and stochastic timed Petri net. The state equation of stochastic timed Petri net with conflict and multi-transitions is received.

Based on a well‐established in vitro directed differentiation model and an integrated analysis of high‐density cell lineage trees (CLTs) and single‐cell transcriptomes, it is demonstrated that many subclones are formed by sub‐CLTs resembling each other in terms of both cell type compositions and topological structures.

Boundedness on Stochastic Petri Nets
Stochastic Petri nets generalize the notionof queueing systems and are a useful tnodel in perfonnance evaiuation ofparaflel anO distributed systems. wc give necessary anO sufficient conditions for the boundedness of a stochastic process related to these nets.

ABSTRACT This study sets out to investigate the prospects for raising oil palm output in sub‐Saharan Africa, particularly Ghana, without further expansion of cropland. Given global concerns about oil palm's role in deforestation and land use change, the focus is on enhancing productivity on existing farmlands.

On Fault Diagnosis of random Free-choice Petri Nets [PDF]
This paper presents an on-line diagnosis algorithm for Petri nets where a priori probabilistic knowledge about the plant operation is available. We follow the method developed by Benveniste, Fabre, and Haar to assign probabilities to configurations in a ...
