Abstract: A method and system allow monitoring a manufacturing process. The process is executed at a plant. Data is acquired from the plant about the state of the plant and/or of parts thereof. The data are converted into Gantt charts. An HTML file is thereby created and sent to browsers of the clients for rendering, and a data record is asynchronously refreshed, including information about a current state of the monitored plant and/or part thereof.

Abstract: A method and a system execute operations, called jobs, via an APM model, in a MES system. The job execution is requested in an application defining an abstract Job class. The abstract Job class includes: an abstract method for job execution, called Execute, wherein a set of jobs to be executed is implemented, at engineering time, within the Execute method, when implementing a set of classes derived from the abstract Job class; a method for executing the job in asynchronous mode, called ExecuteAsync, the ExecuteAsync method runs the Execute method by following APM rules; and a method for executing the job in synchronous mode, called WaitForExecution, the WaitForExecution method runs the ExecuteAsync method waiting for its completion. At run time, by the application, requests the job execution in asynchronous mode by invoking directly the ExecuteAsync method or in synchronous mode by invoking the WaitForExecution method.
