Improving Business Process Efficiency for Supply Chain Finance: Empirical Analysis and Optimization Based on Stochastic Petri Net [PDF]

open access: goldIEEE Access, 2020
Efficient business process is important to the operations of supply chain finance (SCF). Many deficiencies exist in the processes of SCF such as complicated workflows and high time-consuming steps. However, few studies have paid attention to evaluate and

Enhancing Stochastic Petri Net-based Remaining Time Prediction using k-Nearest Neighbors [PDF]

open access: greenATAED@Petri Nets, 2022
Reliable remaining time prediction of ongoing business processes is a highly relevant topic. One example is order delivery, a key competitive factor in e.g. retailing as it is a main driver of customer satisfaction.

Analysis of Petri Net Models through Stochastic Differential Equations

open access: green, 2014
It is well known, mainly because of the work of Kurtz, that density dependent Markov chains can be approximated by sets of ordinary differential equations (ODEs) when their indexing parameter grows very large.

Stochastic Petri Net Simulation [PDF]

open access: green1989 Winter Simulation Conference Proceedings, 2005
Petri nets are a formal modelling tool very well suited to the description of distributed and concurrent systems which exhibit synchronization and contention for shared resources. Adding random temporal specifications to Petri nets, stochastic Petri nets are obtained from which event driven simulators can be automatically constructed.
