In today’s changeable and uncertain environment such challenges as shorter life cycles of products and technologies, shorter delivery times, high level of products customization, increased product variety, high product quality expectations, or demand variability necessitate that manufacturing system/process reliability is to be considered as a major performance parameter.
Based on the literature review given in (Chlebus and Werbińska-Wojciechowska, in press), authors propose the production process reliability definition as an ability of a production system to completely fulfil the production plan of fully valuable final products in a specified period of time under stated conditions. Following this definition, reliability modelling process of production system performance needs the existence of various problems connected with e.g. possible machines and equipment unreliability recognizing and analyzing. Moreover, taking into account the subjectivity of expert opinions, lack of information, and the variety of approaches to reliability assessment problems, authors conclude that this research area still demands further investigation and development of new complex framework for production system reliability measurement.
As a result, the study is aimed at the development of nine-stated Markov model for production system/process reliability assessment, that bases on the proposed multidimensional reliability definition.The presented article gives the first attempt for development and investigation of production process reliability assessment method that helps decision managers in their every-day work.
Contemporary supply chains of particular industrial branches are getting, in consequence of business markets globalization, still more complex and material flows streaming in them are getting still more bulky. The bulky material flows in inner or in outer supply chains should be effectively planned, managed and controlled in context of long-term sustainable socio-economic development and living environment protection. Well, enterprise management systems – one of them is also purchasing management system; should be designed in the way to be possible to reach required level of stability and simultaneously to reach required level of flexibility.
The combination of decisions regarding inventory management and vehicle routing decision leads to complex combinatorial optimization problem called the Inventory Routing Problem (IRP). Several heuristic algorithms for solving IRP were proposed in recent years. A lot of those proposals are based on static and deterministic versions of IRP. Based on our management experience we identified a lot of situations where the VMI approach is used but the dynamic version of the IRP has to be considered. Such situations occur in case of LPG and fuel supplies to fuel stations. There are some proposals of heuristic policies which can be used in above mentioned circumstances. While the advantage of stochastic information is used in heuristic rules, we based on information which is as current as possible. In our proposal after each delivery the optimization models are applied in order to optimize routes and delivery dates. In our paper we presented the combined use of optimization models and discrete event simulation to evaluate the influence of different variability of selected models’ parameters on final plan. Simulation models have proved very useful as an aid to build dynamic and robust plans for considered inventory routing problem. We presented results of extensive simulation analysis of randomly generated cases for comparison our proposals and some policy solutions. Among other it is showed that for some values of parameters such as forecast errors and distribution system structure we can propose better solutions.
In the paper will be presented the way performing the studies, particularly the selection and characterization of the survey sample and the analytical scheme of research. The results of this study will enable to answer the following questions: whether the use of JIT increases the likelihood and consequences of disruption, whether the nature of the product has an impact on the probability of disruptions and whether JIT has been applied in an appropriate way.
Sustainability is a hot issue, implemented at different levels, including whole world, regions, countries, cities/villages and companies. In the presented paper authors are focused on sustainability at the company level, which may be seen as a source of the competitiveness. Running a sustainable business requires appropriate system of measurement, supplying useful information for the decision-makers. Authors choose indicators as a tool for sustainability measurement. In the study, there is presented the method of sustainability indicators system determination at the company level, which takes into consideration all levels of sustainability realization. System of indicators prepared according to the proposed procedure addresses all aspects of sustainability at operational level, including the specific of the business activity as well as cultural and economic conditions characteristic for each region/country. The presented methodology was used in order to prepare the SISc for recycling companies, supporting sustainable policy realization in Poland.
On the study basis the authors found the presence of a gap in the research area of a risk management of urban transportation systems. There is relatively small amount of publications on risk analysis for the urban transportation systems. At the same time, the results already described concern the issues associated with the safety of infrastructure and the accidents. In the published results of researches conducted in Poland and around the world there is a lack of an interdisciplinary approach to risk management in urban transportation systems, in accordance with the holistic approach of ISO 31000. Therefore, it seems important to carry out interdisciplinary research related to the identification of risk factors present in the systems of urban transportation, including technical, economic and social aspects. Special importance has also the assessment of sensitivity of transport processes on the occurrence of defined risk factors and their impact on quality of inhabitants life. The main aim of the article is to present the assumptions currently initiated by the authors of the research project for the creation of an interdisciplinary model of operational risk management system for the urban transportation system including buses and trams, which improves the reliability and life quality of inhabitants.
A company is like its processes and process awareness is half the battle in case of implementing modern IT tools for process mapping and modelling.
Thanks to modelling the processes can be seen in a very realistic way taking into account many real limitations and also including random parameters which illustrate random factors.
The tool for process mapping and modelling is the BPMN notation which lets us model very complex processes, analyse and constantly improve logistics processes on the basis of analysed costs, time, bottlenecks, resources and relationships with other processes.
Taking any decision is always associated with risk. Every decision is related to uncertainty connected with the future, because you can never reliably determine how the factors underlying the current decision will shape the future [1]. At the same time, each type of risk is a source of costs, which include: funds paid to reduce the risk, the funds used to finance the risk, costs resulting from the discontinuation of certain activities because of the connected risk, or the cost of the lack of a certain losses refunding. Therefore, it observed the increasing entrepreneurs' awareness concerning the need to implement tools to assess and monitor risk in their everyday operations. In the last few years, we have seen a significant development of the concept of risk management, driven primarily by common decision-making needs of managers and highly changing organizations’ operational environment. Information technology supporting risk management in organizations has not kept pace for conceptual development. On the Polish market, there is only a few IT products whose functionality does not always conform to the standards of ISO 31000 and the specifics of the sector. Lack of appropriate tools to support decision-making processes is to be the main problem reported by the managers responsible for risk management. Following this, the aim of this article is to present the objectives of the research project on a risk management system that will support decision-making processes of managers in road freight companies.
