Based on the manufacturing scenarios and defined
engineering changes the interactions of multiple, parallel
engineering changes have to be analyzed. For this
purpose, the work steps for each engineering change have
to be planned. Subsequently, several engineering changes
are summarized and the joint implementation is planned.
The implementation of single engineering changes is
compared to the common implementation of several
engineering changes. The differences are figured out, in
order to identify the dependencies and interactions
between engineering changes.
For the planning of individual engineering changes the
implementation cost and how long the manufacturing
would have to be interrupted will be determined.
Therefore, the necessary steps are identified for the
implementation of an engineering change. The
description of these steps involves firstly the required
resources and their use within hours of operations.
Secondly, the description includes information on the
duration of interruptions in manufacturing. The costs of
the respective operations are determined with the hourly
rates which are stored in the database. The work steps are
stored with the associated resources in tables.
Implementation of engineering changes consists of
several steps that are placed and terminated in a useful
order.
