摘要： The present invention discloses a method for generating a production schedule for the operation of a number of resources involved in a number of production processes, each production process comprising a number of production operations and optionally a number of unproductive operations, said method comprising the steps of:
a) providing a list of all available production resources, such as machines and/or materials,
b) providing a list of production orders including the information of all possible sets of productive operations and logical dependencies between them to produce a requested product,
c) determining a set of unproductive operations that must be considered during the production schedule generation along with the information which production resources are able to execute these unproductive operations and under which circumstances these unproductive operations are required;
d) dispatching the productive operations one after another while additionally checking for the a priori or a posteriori need of unproductive operations and dispatching each of these productive operations and the additionally required unproductive operations explicitly by assigning resource occupation time slots on the corresponding machines under consideration of all logical dependencies and/or material requirements;
e) incorporating that mechanism into a schedule generation scheme that either iteratively takes such dispatching decisions before their actual execution in order to come up with a predictive production schedule or into an ad-hoc dispatching algorithm in which each decision is carried out right away; and
f) executing the production order by operating the number of production processes according to the production schedule.
Therefore, the present invention provides an MES functionality which includes a framework that also accounts for unproductive operations in the scheduling process. This framework approach can be applied to any schedule generation scheme that iteratively constructs the schedule by dispatching one operation after another.
