Controllable Deadlocks in Parallel Resource-Constrained Workflows

open access: yesМоделирование и анализ информационных систем, 2014
We study the verification of the soundness property for workflow nets extended with resources. A workflow is sound if it terminates properly (no deadlocks and livelocks are possible).

Who Cares About Carbon Performance Strategy? Ownership Structure as a Driver for Carbon Performance

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This research aims to highlight the empirical, theoretical, and corporate governance arguments employed in the academic literature that examines ownership structure as a determinant of carbon performance—a key element in contemporary climate governance frameworks.

Enabling Circular Economy Performance Through Organizational Capabilities: The Mediating Role of Circular Business Model Innovation

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT The transition to a circular economy requires firms to mobilize organizational capabilities that redesign how value is created, delivered, and captured. Although Circular Business Model Innovation (CBMI) has emerged as the central operational mechanism for circular transformation, the capability stack that triggers CBMI and the ...

Energy Flexibilization and Demand Response for a Novel Decentralized Power‐to‐Methanol Process

open access: yesChemie Ingenieur Technik, EarlyView.
This study presents the results of an optimization framework for the scheduling of a Power‐to‐methanol process coupled with an electrolyser, renewable energy sources and a battery. The optimal dynamic operating schedule is computed with different configurations and boundary conditions, showing the advantages of flexible operation.

A Set Covering Approach to Design Maximally Permissive Supervisors for Flexible Manufacturing Systems

open access: yesMathematics
The supervisory control of Petri nets aims to enforce the undesired behavior as unreachable by designing a set of control places. This work presents a set cover approach to design maximally permissive supervisors.

First Operation Results of a Methanol Demonstration Plant With Real Steel Mill Gases

open access: yesChemie Ingenieur Technik, EarlyView.
A demonstration plant with industrial setup regarding length, diameter, boiling water cooling system and gas recycle was initially operated with cleaned blast furnace gas and compared with earlier experiments with bottle gases. Dynamic disturbances from the steel mill and gas cleaning unit were noticed and could be compensated by the control system ...

Strict Minimal Siphon-Based Colored Petri Net Supervisor Synthesis for Automated Manufacturing Systems With Unreliable Resources

open access: yesIEEE Access, 2020
Various deadlock control policies for automated manufacturing systems with reliable and shared resources have been developed, based on Petri nets. In practical applications, a resource may be unreliable.
