High resolution supply chain management: optimized processes based on self-optimizing control loops and real time data

The efficient dealing with the dynamic environment of production industries is one of the most challenging tasks of Supply Chain Management in high-wage countries. Relevant and current information are still not used sufficiently, to handle the influence of the dynamic environment on intra- and inter-company order processing adequately. Among other things, the problem is caused by missing or delayed feedback of relevant data. As a consequence of that, planning results differ from the actual situation of production. High Resolution Supply Chain Management describes an approach aiming on high information transparency in supply chains in combination with decentralized, self-optimizing control loops for Production Planning and Control. The final objective is to enable manufacturing companies to produce efficiently and to be able to react to order-variations at any time, requiring process structures to be most flexible.

Self-optimising Production Systems

One of the central success factors for production in high-wage countries is the solution of the conflict that can be described with the term “planning efficiency”. Planning efficiency describes the relationship between the expenditure of planning and the profit generated by these expenditures. From the viewpoint of a successful business management, the challenge is to dynamically find the optimum between detailed planning and the immediate arrangement of the value stream. Planning-oriented approaches try to model the production system with as many of its characteristics and parameters as possible in order to avoid uncertainties and to allow rational decisions based on these models. The success of a planning-oriented approach depends on the transparency of business and production processes and on the quality of the applied models. Even though planning-oriented approaches are supported by a multitude of systems in industrial practice, an effective realisation is very intricate, so these models with their inherent structures tend to be matched to a current stationary condition of an enterprise. Every change within this enterprise, whether inherently structural or driven by altered input parameters, thus requires continuous updating and adjustment. This process is very cost-intensive and time-consuming; a direct transfer onto other enterprises or even other processes within the same enterprise is often impossible. This is also a result of the fact that planning usually occurs a priori and not in real-time. Therefore it is hard for completely planning-oriented systems to react to spontaneous deviations because the knowledge about those naturally only comes a posteriori.

High Resolution Supply Chain Management – Resolution of the Polylemma of Production by Information Transparency and Organizational Integration

High Resolution Supply Chain Management (HRSCM) aims to stop the trend of continuously increasing planning complexity. Today, companies in high-wage countries mostly strive for further optimization of their processes with sophisticated, capital-intensive planning approaches [3]. The capability to adapt flexibly to dynamically changing conditions is limited by the inflexible and centralized planning logic. Thus, flexibility is reached currently by expensive inventory stocks and overcapacities in order to cope with rescheduling of supply or delivery. HRSCM describes the establishment of a complete information transparency in supply chains with the goal of assuring the availability of goods through decentralized, self-optimizing control loops for Production Planning and Control (PPC). By this HRSCM pursues the idea of enabling organizational structures and processes to adapt to dynamic conditions. The basis for this new PPC Model are stable processes, consistent customer orientation, increased capacity flexibility and the understanding of production systems as viable, socio-technical systems [1, 2].

Real-time capable Production Planning and Control in the Order Management of builtto- order Companies

In this paper, an innovative approach for a production planning and control, fitting the specific requirements of built-toorder companies, will be shown. The model is based on a cybernetic structure, which follows the restrictions of changeability and viability. As the basic part of the model, a general closed-loop will be designed under consideration of real-time efforts. In a next step, the general closed-loop will be validated by modeling and implementing a precise closed-loop for a dynamic ‘Delivery Date Determination and Control’ for built-to-order companies.

Informationssysteme für das Logistikmanagement

Die wachsende Bedeutung der Informationssysteme begrundet sich durch technologische Entwicklungen und die Stuckkostenentwicklung des Produktionsfaktors Information. So hat sich das Verhaltnis des Preises zur Leistung fur Informationssysteme von den 50er bis in die 70er Jahre jahrlich um 25 % verbessert“ [1]. Mehr denn je dienen Informationssysteme heutzutage einer effizienten Auftragsabwicklung, Unternehmenssteuerung und –planung. In Abschn. 7.1.1 werden die grundlegenden Begriffe definiert und deren Bedeutung erlautert. Im weiteren Verlauf wird eine Einordnung in den betriebswirtschaftlichen Kontext vorgenommen (Abschn. 7.1.2). Abschliesend werden in Abschn. 7.1.4 die aktuellen Herausforderungen vorgestellt und im wissenschaftlichen Zusammenhang diskutiert.

Delivery Reliability in Machinery and Equipment Industry: A European Study

European machinery and equipment manufacturers face multiple logistical challenges in their daily business. Interacting in complex non-hierarchical production networks and thus living with the consequences of a lack of transparency, temporal instability, or imbalanced share of market power finally leads to an inadequate OEM’s delivery adherence which in many cases can be traced back to suppliers’ late deliveries. This paper presents a framework for improving delivery reliability in non-hierarchical production networks by applying market mechanisms. Knowing the financial consequences of a supplier’s belated delivery provides useful information which can be applied in terms of financial incentives. The framework is supported by the results of a study which has been conducted by the authors throughout German, Spanish, and Italian machine tool manufacturers and their suppliers.

High Resolution Supply Chain Management – A Structural Model for Optimized Planning Processes Based on Real-Time Data

The following paper presents an approach for enabling manufacturing companies to cope with dynamic environment conditions and the increasing planning complexity of present supply chains. High Resolution Supply Chain Management (HRSCM) strives to meet these challenges by applying cybernetic principles to the Production Planning and Control (PPC). Therefore, standardized information channels and coordination mechanisms are defined to be able to react even faster and more flexible. The presented structure of the HRSCM is derived from principles of the Viable System Model. Based on this the different system elements of the HRSCM, their functions and their interactions are described. Finally it is outlined how the developed model will be experimentally evaluated and gradually enhanced in future to enable improved decisions on all levels of production under volatile environmental conditions.

Echtzeitfähige Produktionsplanung und -regelung

Kurzfassung In diesem Artikel wird ein innovativer Ansatz für eine Produktionsplanung und -regelung vorgestellt, der den speziellen Bedürfnissen von Auftragsfertigern gerecht wird. Das Modell basiert auf einer kybernetischen Struktur, welche den Beschränkungen der Wandlungs- und Lebensfähigkeit folgt. Als grundlegender Teil dieses Modells wird eine generelle Regelung unter Berücksichtigung des Echtzeitaufwands entworfen.
