A business process is enacted in a production facility employing a computer managed manufacturing execution system or manufacturing operation management system. The MES/MOM systems operate in an event-driven environment based on handlers orchestrated by events. The method includes: providing and parsing a business process model; creating precompiled, closed source command handlers and event handlers; creating entities of a work process model in an operational domain of the system; and, based on the work process model, running a work process, instancing the business process, by using the precompiled, closed source command handlers and event handlers, the command handlers working on tokens that are differentiated for the different types of elements, are created by the command handlers for each element in a run provided for by the enactment and, for each element, are differentiated according to whether the run to which the token belongs is actually executed or skipped.

A manufacturing plant with an MES system is controlled through the execution of a given workflow. a) A plant designer application models a representation of the manufacturing plant through a set of equipment objects and through a workflow, b) a complex entity (plugin) is provided for expanding the characteristics of an equipment object; the plugin exposing an interface with a configuration, a set of property elements, a set of functionality elements; c) at engineering time, designing a set of plugins usable by the set of equipment objects; d) at engineering time, for at least one equipment object, associating at least one plugin; e) defining, through the plant designer, a given workflow according to given customer requirements, the workflow including an interaction with an element of a plugin associated with an equipment object; f) at runtime, executing the given workflow and performing the interaction with the element of the plugin.

A custom function is defined at engineering time for implementing actions to be executed in case of a disconnection event in which a client is unable to communicate with a server. At engineering time, code specifying the action to be implemented by the custom function is written into a function file that is stored on the web-server. Subsequently at run time, a browser running on a client requests a certain page to be displayed from the web-server. On occasion of a client-server disconnection; the communication component notifies a certain displayed page about the disconnection; and the custom function is executed with certain page being displayed.
