SERVICE LEVEL MODELING IN THE SUPPLY CHAIN WITH THE USAGE OF SOLUTIONS BASED ON DECOUPLING POINT CONCEPT
Ireneusz Fechner
1
The customers demand often requires to be satisfied within time, which is shorter than the real time necessary for manufacturing and delivering a product to a consignee. In a traditional supply chain the uncertainty of a forecast based on inflowing orders is repeatedly a reason for its delayed response to the market needs, and gathering excessive stock in comparison with real requirements is a counteracting method. However, there is a possibility of implementing a faster and more efficient supply chain reaction to consumers' behaviours. It is especially important when dealing with frequently purchased consumer products. Due to the popularization of automatic identification and EDI systems, it is possible for the final supply chain links to make the data on sales and stock available to manufacturers and suppliers co-operating with them as a result of which the supply chain may undertake activities steered with demand. The effect of such activities is a better accuracy of forecasts and the possibility to eliminate stocks excessive in comparison with real demand.

RULES FOR MODELLING AND REDESIGNING SUPPLY CHAINS
Wacław Szymanowski
1
This paper's goal is description of modeling and designing terms for supply chains. The most efficient method is the application of the supply chain permanent improvement rule. This rule was defined 1993 by T. Davenport and based on the evolutionary approach to the redesigning/reengineering of economic processes. The application of this rule for planning purposes is facilitated by the W. Deming's PDCA (Plan-Do-Check-Act) rule adapted later by J.B. Ayers for supply chains design. The supply chain reengineering rules are executed in three stages: design concept stage, detailed design stage, execution stage. The paper's last part regards the selection of evaluation criteria for the supply chain variant chosen to be redesigned.

KNOWLEDGE MANAGEMENT AND LOGISTICS: WHERE WE ARE AND WHERE WE MIGHT GO TO
Gaby Neumann

Eduardo Tomé

By the commonly accepted theory, today's logistics processes and systems are characterized by an increasing complexity and by the need for global networking to cope with the growing diversity of logistics problems; because of this, knowledge is becoming more and more a strategic resource in logistics.
But some questions remain unanswered: How far has implementation of knowledge management methods gone in the logistics practice? To what degree does the supposed (theoretical) relevance of investments into knowledge and knowledge management match the actual priority of several knowledge management activities as shown by the respective investment volume? How do knowledge-related investments change a company's logistics performance?
In order to answer those questions, a survey was run with German and Portuguese logistics companies on the relevance of knowledge and knowledge management for executing logistics processes, on the need of investment into knowledge and knowledge management activities in logistics, and on the eventually existent relationship between knowledge and logistics performance. To analyze the impact of knowledge management on a company's logistics performance a model has been developed which contributes to an economic assessment of knowledge management and the analysis of its potentials. As a result, a qualitative determination of the state-of-the-art in implementing and applying knowledge management in the logistics practice was produced. Specifically, severe differences between the German and Portuguese reality turned out, although it has been quite challenging to derive statistical benchmarks for an optimal use of knowledge in logistics from the small amount of responses received.
The paper will present conclusions drawn from the use of the methodology and a list of recommended actions derived from this respectively.

ANTROUTE - LARGE SCALE DYNAMIC OPTIMISATION OF VEHICLE ROUTES AND FLEETS
Dario Coltorti
1
The software product AntRoute is developed by AntOptima, a spin off company of the Swiss Research Institute for Artificial Intelligence IDSIA, Istituto Dalle Molle di Studi sull'Intelligenza Artificiale. IDSIA is one of the leading Institutes in Ant Colony Optimization (ACO), a powerful method to solve different types of combinatorial optimization problems, especially vehicle routing.
The developed algorithms are among the best currently worldwide available and they have found new best-known solutions for many benchmark instances.
With AntRoute AntOptima implements this technology for Logistics provider to speed up their business in terms of time and efficiency. The integrated high performance Tour Optimizer of AntRoute based on ACO and is automatically able to optimize thousands of daily orders in a few minutes considering the company related constraints like truck f

LOCALIZATION OF SOFTWARE IN LOGISTICS
Marek Matulewski
1
The author presents the problems connected with localization of logistic software. The following factors affecting the process of localization are discussed: information and it role, globalization, internationality and the command of foreign languages. Three types of localization depending on the type of interaction are taken into consideration. The main emphasis is put on the efficiency decrease, which is observed in the case of logistic software as a result of communication distortions. SAP R/3 logistic software was used as an example illustrating the localization problems. Three situations have been presented namely: lack of localization, partial localization and deficient complete localization, which is hard to understand for the users. The author concludes that even high-quality software in the case of the lack of or partial localization becomes less efficient and effective than in the case of complete localization. But the lack of localization finds its justification in the age of globalization.
