    Application-Architecture of an ERP-System for the era of Industry 4.0
    (INFORMATIK 2021, 2021) Herlyn, Wilmjakob Johannes
    In this paper we design an architecture of a future ERP-System that bases on the concept of a Digital Control Twin as its kernel. ‘Architecture’ in this paper means how the different applications of an ERP-System work together in combination with the Operation Control System of the Computer. The architecture is designed in the way that a lot of EPR-Applications are integrated in only one System. Nowadays the ERP-applications are separated modules like Master Production Scheduling and Manufacturing Execution or Material Requirement Planning, Warehouse Management, Transportation Control or JIT-Call-Offs which causes a loss of data consistency and accuracy and a lack of response-time and adjustment consequently. Classical ERP-Systems bases on the Waterfall-Model with no direct recursion of results to a preceding module. This architecture is no more suitable for the capabilities of industry 4.0 e. g. to exploit the huge amount of permanent available data and to react instantly on disturbances in production, transportation, storing or handling. The proposed architecture is a kind of Design Science Research approach that bases on the knowledge and experience in one of the biggest automotive OEM in the departments of IT, Purchasing, Production, Logistic and Sales.

    ERP implementation effort estimation using data envelopment analysis
    (Business Information Systems – 9th International Conference on Business Information Systems (BIS 2006), 2006) Koch, Stefan
    ERP implementation projects have been encountered as very risky and complex, and frequently exhibit time and cost overruns. Therefore both a comparison of their efficiency, and especially an estimation of effort and costs associated with new projects are of high interest. Since ERP implementation differs from classical software development projects, as the main focus lies on adapting and customizing a complex system, and even changing the organisation, traditional models like COCOMO can not easily be applied. The non-parametric DEA on the other hand has been developed to compare the efficiency of units with multiple inputs and outputs with different measurement scales. In this paper, we will describe the application of DEA using a data set of 39 projects, drawing on the results of applying DEA for effort estimation of future projects.
