- displaying a current production schedule by way of a Gantt-chart;
displaying in the Gantt-chart for each piece of equipment of the shop floor time periods already scheduled and time periods still unscheduled;
selecting for a specific piece of equipment a time period still unscheduled;
querying a production database for the specific piece of equipment to find at least one task that fits into the time period still unscheduled; and
if a single task is found, scheduling the task, or if a plurality of tasks are found, scheduling at least one of the plurality of tasks, by way of a decision entered by a user interaction or by way of a decision determined automatically by a selection preference.

Abstract
A method and a system for scheduling a manufacturing process planned by an enterprise resource planning and produced by equipment on a shop floor. A production scheduler within a manufacturing executing system schedules tasks of the manufacturing process. The production scheduler is enabled to display the current production schedule in a Gantt-chart and it is enabled to display for each equipment of the shop floor the time periods that are already scheduled and those time periods that are still unscheduled. A selector selects a specific equipment a time period still unscheduled. A query module is provided for querying a production database for this specific equipment to find at least one task that fits into the time period still unscheduled. The production scheduler is enabled to schedule the task in case of a single task found or in case of a plurality of tasks found schedule at least one of the tasks found by means of a decision entered by an user interaction or by means of a decision determined automatically by a selection preference.
