Sensitivity Analysis And Optimization For Selected Supply Chain Management Issues In The Company – Using System Dynamics And Vensim, Elżbieta Kasperska, Elwira Mateja-Losa, Rafał Marjasz Jan 2013

Sensitivity Analysis And Optimization For Selected Supply Chain Management Issues In The Company – Using System Dynamics And Vensim, Elżbieta Kasperska, Elwira Mateja-Losa, Rafał Marjasz

Journal of Entrepreneurship, Management and Innovation JEMI

The aim of our paper is to present the new results of research work on optimization and simulation for some logistic problems in the company. The System Dynamics (SD) method and the Vensim simulation language are applied in order to solve specific managerial problems described by Forrester in the model of supply chain. The historical model of Customer-Producer-Employment System by Forrester (Forrester, 1961) has not been examined with the sensitivity analysis, from the “automatic” testing perspective. Optimization experiments have not been conducted, either. It is surprising, since the model is old and widely known. The opportunities offered by the Vensim …


Validation Of System Dynamics Models – A Case Study, Justyna Lemke, Małgorzata Łatuszyńska Jan 2013

Validation Of System Dynamics Models – A Case Study, Justyna Lemke, Małgorzata Łatuszyńska

Journal of Entrepreneurship, Management and Innovation JEMI

The purpose of this article is the analysis of the system dynamics model validation illustrated by the example of a model of the manufacturing resource allocation. In the first part of the article the authors present an overview of the definitions of validation and verification that can be found in the reference literature. Also, they emphasize the role which validation and verification play in the modeling process. Furthermore, they discuss the techniques of system dynamics model validation with particular focus on tests of the model structure, behavior and policy implications. The second part of the article contains an example of …


Technology Transfers And Knowledge Management In Developing Economies: Case Study Of An Indonesian Manufacturer, Wahyudi Wibowo Jan 2013

Technology Transfers And Knowledge Management In Developing Economies: Case Study Of An Indonesian Manufacturer, Wahyudi Wibowo

Journal of Entrepreneurship, Management and Innovation JEMI

International technology transfers are crucial for developing economies since they may operate as one of the key drivers in the economies’ development path. Previous studies have acknowleged some channels of technology transfers for developing economies. Nevertheless, the precise mechanisms of how the technology transfers would occur and take effect in each of the recipient economies and their domestic companies are still to be explored. Furthermore, understanding domestic companies knowledge management is important since it would determine the absorptive capacity of the company toward advanced foreign technologies. This study uses a case of technologically intermediate-level Indonesian manufacturer to show evidence of …


The Modeling Process Of The Materials Management System In A Manufacturing Company Based On The System Dynamics Method, Małgorzata Baran Jan 2013

The Modeling Process Of The Materials Management System In A Manufacturing Company Based On The System Dynamics Method, Małgorzata Baran

Journal of Entrepreneurship, Management and Innovation JEMI

The article presents the steps of modeling of the material management system in a manufacturing company. First, the modeling procedures indicating by Forrester, Łukaszewicz, Souček, Tarajkowski and Sterman were described and the essence of materials management in a manufacturing company was presented. Next, modeling of the materials management system was shown - step by step. Initially, the variables of the mental model connected with materials were defined, then variables in casual loop diagrams were linked. Diagrams were transformed into a simulation model that has been verified. The validation of the simulation model was conducted by using the following methods: assessing …
