PERFORMANCE MODELING OF E-PROCUREMENT WORKFLOW USING GENERALISED STOCHASTIC PETRI NET (GSPN)

Journal of ICT, 2022
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.

Stereotyped Subclones Revealed by High‐Density Single‐Cell Lineage Tracing Support Robust Development

Advanced Science, EarlyView.
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

Revista Matemática Complutense, 1993
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.

Charting the Path to Increased Oil Palm Output in Ghana Beyond Area Expansion: Technology or Managerial Capacity — Which Leads the Way?

Agribusiness, EarlyView.
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]

, 2009
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 ...

A Bioprocess Engineering Approach to Boost Selection of Fully Segregated Transformants in Cyanobacteria

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Cyanobacteria are photoautotrophic microorganisms with significant applications in biotechnology. Although many cyanobacteria, including Picosynechococcus sp. (formerly called Synechococcus sp.) PCC 11901 (Picosynechococcus) and Synechocystis sp.
