Initial situation: 

The formation of order sequences within the framework of order processing on work systems in manufacturing companies takes place within a conflict of objectives between the cost-related target quantity productivity and the logistic performance-related target quantity adherence to delivery dates. In order to be able to carry out a goal-oriented positioning within the field of tension under consideration of the company- and market-specific requirements, it is therefore necessary to know the quantitative effects of sequence rules on the productivity and schedule deviation behaviour of work systems. It should be noted here that there is typically a link between the work systems in production areas, whereby changes to a work system also affect the subsequent systems. The question arises as to what a strategy for determining the order sequences in individual work systems can look like, which takes into account the total performance and the total costs of a production area and makes the behaviour of the area predictable.

Objective:

In previous research projects, the fundamental relationships between different rules for order sequencing and the resulting schedule deviation as well as productivity were investigated and modelled at individual work systems. The next step is to transfer the collected findings to industrial application. The goal of the project is the development of a procedure model for the definition of a logistic-oriented sequence strategy for production areas. For this purpose, the logistic effects of different sequence rules on the schedule deviation behaviour as well as productivity gains of individual work systems must be quantitatively assessable under consideration of conflicting target values and compensation measures.

Approach:

Together with our cooperation partner Koenig & Bauer Industrial AG & Co. KG to achieve the project objective is divided into four work packages (WP). First, the order processing processes in the selected pilot area are recorded and the work systems are subjected to a logistical analysis in order to record the current logistical situation (WP 1). In the next step, the models developed at the IFA to describe the effects of succession rules on logistical target variables will be examined with regard to their applicability with regard to the specific framework conditions and subsequently extended accordingly and supplemented by new models (WP 2). In order to ensure a sustainable transfer of the models into practice, a user-friendly software demonstrator for the automated, data-based evaluation of the three sequence rules mentioned for individual work systems and their linkage will also be programmed (WP 3). Finally, a procedure for the derivation of logistic-oriented sequence strategies under consideration of logistic compensation measures with regard to entrepreneurial objectives is developed and a sequence strategy for the considered pilot area is derived (WP 4).
