The challenge for management is to recommend an optimal network configuration that will allow for longer term optimal results despite of environmental turbulences. This paper studies the robustness of cost-optimized FMCG (fast-moving consumer goods) distribution networks. It aims at observing the impact of changing variables/conditions on optimized logistic structures in terms of the optimal number and geographical locations of existing distribution centers. Five variables have been identified as relevant to the network structure. A case study approach is applied to study the robustness of an existing, typical, and optimized FMCG network. First, distribution network data of a German manufacturer of FMCG are recorded and analyzed. A quantitative model is set up to reflect the actual cost structure. Second, a cost optimal network configuration is determined as a benchmark for further analysis. Third, the variables investigated are altered to represent changes, both isolated (ceteris paribus) and in combination (scenario analysis). Each one of the variables investigated proves to be fundamentally able to suggest a change of the optimal network structure. However, the scenario analysis indicates that the expected changes will by and large compensate each other, leaving the network in near optimal condition over an extended period of time.}, language = {en} } @incollection{KellnerOttoBusch2012, author = {Kellner, Florian and Otto, Andreas and Busch, Andreas}, title = {Distribution Networks - Rigid Investments In Dynamic Environments}, series = {Flexibility and adaptability of global supply chains - Proceedings of the 7th German-Russian Logistics Workshop (DR-LOG 2012)}, booktitle = {Flexibility and adaptability of global supply chains - Proceedings of the 7th German-Russian Logistics Workshop (DR-LOG 2012)}, editor = {Ivanov, Dimitri and Sokolov, Boris and K{\"a}schel, Joachim}, pages = {103 -- 111}, year = {2012}, language = {en} } @article{KellnerOttoLienland2014, author = {Kellner, Florian and Otto, Andreas and Lienland, Bernhard}, title = {Cost Assignment Paradox: Indirect Tooling Costs and Production Orders}, series = {Advances in Management Accounting}, volume = {23}, journal = {Advances in Management Accounting}, doi = {10.1108/S1474-787120140000023007}, pages = {211 -- 251}, year = {2014}, abstract = {Purpose Tooling is a common component of an industrial product's manufacture. Specific tooling is devised to serve the fabrication of a particular product, while generic tooling can be used in the manufacture of multiple products. In the latter case, companies are confronted with the problem of fairly allocating the indirect costs of the tooling. This article studies how to allocate costs of generic tooling to single production orders. Methodology Ten allocation methods (AMs) are described that are in principle suited to the distribution of generic tooling costs to production orders. Since the presented methods have for the most part been discussed in differing contexts, we apply them to a specified generic tooling problem for comparison. Evaluation of the various methods is based on 16 criteria. Reasoning is supported by a computational Monte Carlo simulation. Furthermore, we suggest using the Analytical Hierarchy Process (AHP) to elaborate one final proposition concerning the most preferable allocation scheme. Findings The article reports the single allocation rules' performances for different allocation scenarios. The described characteristics refer to fairness, efficiency, and simplicity as well as to empty-core performance. Using AHP analysis allows for the aggregation of the rules' criteria ratings. Thus, especially suitable allocation schemes for the problem at hand are identified. Practical implications An allocation is required for budgeting reasons and also for the definition of projects' bottom-up sales prices. Selecting the "right" AM is important, as a suboptimal AM can result in unfair allocation vectors, which will act as incentives to stop using the common resource, potentially leading to higher total costs. Originality/value of the article Research on the comparison of AMs is typically performed for certain purposes, such as enterprise networks, horizontal cooperative purchasing scenarios, or municipal service units. This article will augment the research evaluating AMs by introducing a novel set of evaluation criteria and by providing an in-depth comparison of AMs suited for the allocation of generic tooling costs.}, language = {en} } @article{KellnerOtto2012, author = {Kellner, Florian and Otto, Andreas}, title = {Allocating CO2 emissions to shipments in road freight transportation}, series = {Journal of Management Control}, volume = {22}, journal = {Journal of Management Control}, number = {4}, doi = {10.1007/s00187-011-0143-6}, pages = {451 -- 479}, year = {2012}, abstract = {Logistic activity, in particular transportation, produces green house gases (GHG).

Second, since the majority of these methods has not been designed for allocating GHG, we apply and compare them in the short distance transport context within a numerical example. The aim is to study how the schemes perform according to criteria. We suggest using causality, efficiency, empty core robustness, symmetry, individual rationality, coalition stability, ease of application, and set robustness as appraisal criteria and attempt to mainstream the discussion by recommending selected allocation methods.}, language = {en} } @article{KellnerOttoBrabaender2017, author = {Kellner, Florian and Otto, Andreas and Brab{\"a}nder, Christian}, title = {Bringing infrastructure into pricing in road freight transportation ?

The methodology is applied to five terminals of a forwarding cooperation and has been able to document significant differences in cost per kilometer across the terminals. The research results can be used by logistics service providers to better understand how productivity and thus profitability is affected by the quality of the transportation infrastructure in the particular areas they operate in.
