complexity

The network as a complexity driver gains in importance due to a proceeding globalization. The amount and location of sites are a key part of the network. A growing number of sites raises the complexity causing further coordination efforts, interfaces and opacity. Complexity has not been taken into account within location decisions yet. Thus this article analyses the connection between the amount of sites and complexity.

The primary user-model of enterprise systems is expert-based. It depends on the assumption, that the user has expert knowledge about technical terminology and system functions. This model also assume that developer and user has the same degree of knowledge. This statement cannot be accepted. In the future it is more or less necessary that not-skilled workers are familiar with enterprise systems. For this purpose, the center of enterprise research developed a concept for an enterprise system assistant system. It allows the usage of complex enterprise systems also for less trained users.

Although all approaches to proactive change management of production systems emphasize the relevance of complexity, an integrated building block “management of complexity” is not available. Based on a specification of the domains and dimensions of production complexity a framework for handling complexity is outlined. It covers guidelines, principles and tools for coping with the multiplicity, diversity, ambiguity and dynamics of production systems.

To compete in the global environment companies in high wage countries have to separate themselves from competitors from low wage countries by offering customer specific products and services. Due to the rising complexity of these products the steering of the corresponding production systems is getting more and more resource consuming. One way to handle this aspect is developed within the Excellence Cluster “Integrative production technology for High-wage countries” at RWTH Aachen University. Objective is the set up of production systems that are able to produce customer specific products at mass production costs.

Complexity does not emerge from the drawing-board. Complexity evolves through the permanent attempt of an organization to emerge and distinguish itself from the competition. Complexity penetrates a company on many different levels. The battle to control and, if possible, reduce expensive complexity can not be won by just putting up concepts. What is the best concept good for if the corporate management can not realize it? In practice we observe many executives lacking in pragmatic, down to earth approaches. Most managers are not aware of that. Our experience taught us the following: Initiatives for complexity-reduction are successful when continuous, real-time and action-oriented management information-systems are in use during and after the transformation process. The relevant complexity indicators have to be transferred to management and staff. Both must work proactively to reach the goal of complexity reduction. Last but not least all assigned actions for complexity-reduction have ...

A simple production system enables to customer oriented manufacturing with low cost and high costumer service. The most four important ways to a simple production are covered by: • Reduction of the number of items (finished goods, intermediate as well as purchasing parts) • Setting of clear and non-conflicting objectives as well as prioritizing measurements needed • Organizing of a continuous production flow and • Applying monitoring instruments instead of detailed planning and scheduling tools

The laboratory for machine tools WZL of RWTH Aachen University and Scheidt & Bachmann have jointly developed a methodology for product structure oriented continuous improvement of products and processes. The staff members’ manifold experience with complex products is used effectively by a combination of a product structure oriented assessment and a production portfolio oriented interpretation. Hence, experiences are quantified by the metric “additional effort of time per single use”. This additional effort addresses the coordination and correction expenses, which are typically not quantified and handled by variety-neutral surcharges in the calculation scheme. The methodology is working on the basis of “As-Is” data and not as usual on the basis of planning data like in conventional approaches of variant management. The factual composition of the products is used instead. By applying the methodology for several product families, latent optimization potential could be determined ...

Complexity of industrial enterprises increases. Responsible for this trend are external drivers like the individualisation of products, the fierce global competition and the speed of technological developments which lead to reduced product life and innovation cycles. Companies react to external complexity by building internal complexity, logistics as a cross functional unit is especially affected. For example, a great number of different customers demand a heterogenic product program which results in operating an increasing quantity of variants. Because of the growing internal complexity a lot of promising logistical solutions are not realised. This article shows an approach how to create an organisational framework - based on the formal principle “Modularisation” - which allows logistics to regain adaptability and mutability by reducing internal complexity.

In the last years of general economic depression, European small and medium-sized enterprises (SME) have compensated for the large enterprises’ loss in value and job creation. A trend towards a “pulverization” of the economic system from large to small companies could be noticed. On the other hand, growth is an economic prerequisite for sustainable business success. Must a SME therefore grow and become a large enterprise in order to succeed? Not necessarily. Business growth is not a perpetuum mobile; it is restricted by internal diseconomies of scale and scope caused by the increased complexity of large organizations. In this paper, a new approach is presented which shows how small and medium sized companies can realize sustainable growth without losing the advantages of a small organizational structure.
