Modeling Trading Systems using Petri Net Extensions
P. 118–137.
Trading systems have become sophisticated multi-agent in-frastructures with complex development cycles. This is why the financialindustry constantly seeks for novel approaches to design and validate these systems. We propose the use of models to support such tasks. On the one hand, these models need to describe how objects (e.g., ordersto buy/sell securities) are shared by the system and traders. On the other hand, being a dynamic multi-agent system, models of trading systems should have a clear structure, describing how participants interact between each other. In this paper, we address these requirements, integrating notions of various Petri net extensions. In particular, we discuss modeling capabilities/limitations of each extension, and we propose to integrate them into a single approach, allowing for comprehensive modeling of different trading system components.

Object-centric process mining has emerged as a powerful paradigm for analyzing event data involving multiple interacting business objects. Existing discovery techniques often rely on object-centric Petri nets with fixed arc multiplicities, limiting their ability to represent parametric resource consumption and production patterns and to capture quantitative dependencies between interacting object types. In this paper, we ...

The structure of a process model discovered from an event log of a multi-agent system often does not reflect the system architecture with respect to agent interactions. The existing conformance checking quality dimensions mainly evaluate the extent to which the behavior a discovered model corresponds to event sequences recorded in an event log. These behavioral ...

Process mining is a field of computer science that deals with the discovery and analysis of process models based on automatically generated event logs. Currently, many companies are using this technology to optimize and improve their business processes. However, a discovered process model may be too detailed, sophisticated, and difficult for experts to understand. In ...

Trading systems are software platforms that support the exchange of securities (e.g., company shares) between participants. In this paper, we present a method to search for deviations in trading systems by checking conformance between colored Petri nets and event logs. Colored Petri nets (CPNs) are an extension of Petri nets, a formalism for modeling of ...

Object-centric processes have become increasingly popular in the last years mainly due to the establishment of object-centric process mining. One of the most popular formalisms for describing lifecycles of objects and capturing relationships between them are object-centric Petri nets. An important feature of such nets is the ability to transfer an arbitrary number of same-typed ...

The structure of a process model directly discovered from an event log of a multi-agent system often does not reflect the behavior of individual agents and their interactions. We suggest analyzing the relations between events in an event log to localize actions executed by different agents and involved in their asynchronous interaction. Then, a process ...

Multi-agent pathfinding (MAPF) is a challenging problem which is hard to solve optimally even when simplifying assumptions are adopted, e.g. planar graphs (typically – grids), discretized time, uniform duration of move and wait actions etc. On the other hand, MAPF under such restrictive assumptions (also known as the Classical MAPF) is equivalent to the so-called ...

Recently introduced Petri net-based formalisms advocate the importance of proper representation and management of case objects as well as their co-evolution. In this work we build on top of one of such formalisms and introduce the notion of soundness for it. We demonstrate that for nets with non-deterministic synchronization between case objects, the soundness problem ...

A process model discovered from an event log of a multi-agent system often does not fully cover certain viewpoints of its architecture. We consider those concerned with the structure of a model explicitly reflecting agent behavior and interactions. The direct discovery from an event log of a multi-agent system may result in an unclear model ...

Structural transformations that preserve properties of formal models of concurrent systems make their verification easier. We define structural transformations that allow to abstract and refine elementary net systems. Relations between abstract models and their refinements are formalized using morphisms. Transformations proposed in this paper induce morphisms between elementary net systems as well as preserve their ...

The aim of this paper is to show that any finite undirected bipartite graph can be considered as a polynomial p∈N[x], and any directed finite bipartite graph can be considered as a polynomial p∈N[x,y], and vise verse. We also show that the multiplication in semirings N[x], N[x,y] correspondences to a operations of the corresponding graphs which looks like a ``perturbed'' ...

In this paper, we present an approach to the generation of Petri nets exhibiting desired structural and behavioral properties. Given a reference Petri net, we apply a collection of local refinement transformations, which extends the internal structure of the reference model. The correctness of applying these transformations is justified via Petri net morphisms and by ...

Conformance checking methods diagnose to which extent a real system, whose behavior is recorded in an event log, complies with its specification model, e.g., a Petri net. Nonetheless, the majority of these methods focus on checking isolated process instances, neglecting interaction between instances in a system. Addressing this limitation, a series of object-centric approaches have ...

This paper provides a true-concurrency approach for the specification and verification of systems of concurrent communicating agents with durable actions. We present high-level Petri nets with durable actions (DaHL) to cope with various details in such complex systems. We define a DaHL module as an open variant of time-dependent colored Petri nets. A DaHL system ...

This paper presents a compositional conformance checking approach between nested Petri nets and event logs of multi-agent systems. By projecting an event log onto model components, one can perform conformance checking between each projected log and the corresponding component. We formally demonstrate the validity of our approach proving that, to check fitness of a nested ...
