In this paper we introduced in transport planning based on evolutionary algorithms. The objective is to design a decision support tool for transport planning manager to support the planning process. An important criterion is to minimize the transportation (km) by using this tool. The prototype introduced in this paper was tested with real business data to check the suitability for transportation planning. Furthermore, different settings for the evolutionary algorithm are experimentally studied their utility is verified with statistical tests.

The demographic change will be one of the big challenges for operational logistics in the upcoming years. With the aging of logistics workers, physical constraints increase especially when employment is characterized by high physical stress (e.g. like in production and logistics). That causes higher demands on the design of logistics workplaces. But how can companies react to this, taking into account that value added orientation leads to new demands to workers? Is there a chance that the increasing percentage of elder employees can properly fulfil the demands in the future? Whereas the ergonomic design of workplaces is the precondition, an intelligent labour organisation with diversified stress can preserve the worker’s ability to work.

Autonomous vehicles are employed in intralogistics in order to transport work pieces between different workplaces. Previous guidance systems are based on wire-guided tracks or optical following of surface markings. In the first case, the possibility to change the production layout is rather limited. In the second case, abrasion can significantly decrease recognition rates. In contrast, humans easily succeed in navigation tasks, even in dynamic environments. A promising approach is therefore to apply a cognitively motivated spatial representation for autonomous vehicles. This article presents BA23, a set of 23 qualitative relations for qualitative spatial reasoning, and discusses its application in intralogistics.

With time, products lose their attractiveness on the market, technology becomes outdated or customer demands are no longer met. To keep up success, companies need to replace old products. This means a huge amount of product changes for a manufacturer that differentiates through customer-focused product design and continuous product innovations. Ramp-up and phase-out-management are critical factors of success. As the product life cycles shorten due to the dynamism of the technology and markets, payback periods for the development costs reduce, too. In order to maintain profitability or to increase it, it is necessary to minimise the cost and time of product changes. This article shows how logistics contribute handling a lot of complex ramp-ups and phase-outs with optimal cost and in a short time.

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 ...

In future, classic logistical targets will be supplemented by the target “safeguarding of resources”. In view of the close chaining of logistic processes, holistic and sustainable approaches are needed to achieve an optimum oriented economic and ecological general condition of logistic systems. This article introduces the need of new strategies in logistics and the relevance of new concepts to increasing the logistical performance.

Confronted with intensive product price competition in China, industrial firms are forced to invest in extending the service business. Extending the service business is far from easy. Chinese competitors offer faked spare parts. Local service skills are very poor and service requirements force industrial firms to invest in logistic infrastructure. This article offers a guideline for managers seeking to professionalize the human resource management in the service organization, to adapt service offerings to the local customer needs, and to set-up a logistic infrastructure.

Given the current and anticipated future economic development in China, annual growth rates around 10 % and the opening of the Chinese market to logistics services, foreign logistics service providers are expecting annual growth of 30 % in this particularly lucrative market segment. One of the greatest challenges is the lack of sufficiently qualified Chinese logistics experts. This presents foreign research organizations and enterprises an opportunity to become active in China.

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.

Production planning within the Mercedes Car Group is challenged by reduction of development times while increasing the product portfolio and quality. New approaches were necessary to implement the factorys needs into the product development as early as possible. 5 Years ago the Digital Factory was founded to secure that no production is started without a digital validation of product, production process and tools. Today the final assembly planning at DaimlerChrysler follows an integrated workflow of final assembly, Logistics and facility planning.
