The paper presents a knowledge conflict resolving in supply chain management systems by using consensus methods. Most often user independently resolves this conflict by analyzing individual variants and taking a decision which of these variants choose. It is time-consumption and process, which is tied with risk of incorrect variant choice. To eliminate these inconveniences it can be use the consensus methods. These methods allow the automatic determine by system one variant, that is presented to the user. Therefore, the knowledge structure, which represents individual variants of solution, was defined in article. This definition is necessary to determine consensus algorithms, which allow to resolving knowledge conflicts supply chain management systems.

Stosowane obecnie systemy informatyczne wspomagają podejmowanie decyzji głównie na szczeblach operacyjnym i taktycznym, natomiast stają się niewystarczające na szczeblu strategicznym. Umożliwiają one bowiem jedynie analizę formy informacji, powiązań pomiędzy wartościami ekonomicznymi, natomiast nie wspomagają procesu analizy ich znaczenia. Zasadne staje się zatem wykorzystanie narzędzi, które realizują funkcje poznawcze i decyzyjne, jakie zachodzą w ludzkim mózgu, dzięki czemu potrafią zrozumieć rzeczywiste znaczenie obserwowanych zjawisk i procesów gospodarczych zachodzących w otoczeniu organizacji. Do narzędzi tych należą między innymi agenty kognitywne, które często współpracują ze sobą w ramach systemu wieloagentowego, aby skutecznie osiągnąć wyznaczony cel. Jedną z najważniejszych cech agentów kognitywnych jest umiejętność uczenia się. W niniejszym artykule dokonano analizy i usystematyzowania metod uczenia się agentów kognitywnych, które mogą być wykorzystane w konkretnych obszarach decyzyjnych wspomaganych przez system informatyczny. W pierwszej części przedstawiono charakterystykę i strukturę wieloagentowego systemu wspomagania decyzji. Następnie omówiono aspekty związane z problematyką architektur agentów kognitywnych. W końcowej części artykułu przedstawiono metody uczenia się agentów wyróżniane ze względu na różne kryteria, które mogą być wykorzystane w odniesieniu do danych obszarów decyzyjnych.

The article presents the issues related to knowledge management by using the integrated management information systems. The aim of the article is to develop the manner of cognitive agent's perceptual memory implementation. The agents run in the prototype of integrated management information system, named CIMIS, which is used in knowledge management process in business organizations. CIMIS is based on the LIDA cognitive agent architecture. The paper draws attention to the business processes integration with the use of the information systems. Using such research methods as literature study, case study and computer simulation, the authors present how to use a topic map standard for perceptual memory implementation. This is very important module of agent's architecture responsible for proper recognition of an object, categories, activities and events occurring both in external and internal agent's environment. The solution presented in this paper allows for automatic interpretation, by an agent, of the phenomena occurring in the enterprise's environment. It has a positive impact on the process of knowledge management. Since the topic map is an international standard, it allows to achieve an interoperability of different information systems.

Shelf space is one of the essential resources in logistic decisions. Order picking is the most time-consuming and labourintensive of the distribution processes in distribution centres. Current research investigates the allocation of shelf space on a rack in a distribution centre and a retail store. The retail store, as well as the distribution centre, offers a large number of shelf storage locations. In this research, multi-orientated capping as a product of the rack allocation method is investigated. Capping allows additional product items to be placed on the rack. We show the linearisation technique with the help of which the models with capping could be linearised and, therefore, an optimal solution could be obtained. The computational experiments compare the quality of results obtained by non-linear and linear models. The proposed technique does not increase the complexity of the initial non-linear problem.

Aim/purpose – Shelf space is one of the most important tools for attracting customers’ attention in a retail store. This paper aims to develop a practical shelf space allocation model with visible vertical and horizontal categories. and formulate it in linear and non-linear forms. Design/methodology/approach – The research is mainly based on operational research. Simulation, mathematical optimization, and linear and nonlinear programming methods are mainly used. Special attention is given to the decision variables and constraints. Changing the dimensioning of the decision variables results in an improvement in the formulation of the problem, which in turn allows for obtaining an optimal solution. Findings – A comparison of the developed shelf space allocation models with visible vertical and horizontal categories in linear and nonlinear forms is presented. The computational experiments were performed with the help of CPLEX solver, which shows that the optimal solution of the linear problem formulation was obtained within a couple of seconds. However, a nonlinear form of this problem found the optimal solution only in 19 out of 45 instances. An increase in the time limits slightly improves the performance of the solutions of the nonlinear form. Research implications/limitations – The main implication of research results for science is related to the possibility of determining an optimal solution to the initially formulated nonlinear shelf space allocation problem. The main implication for practice is to take into consideration the practical constraints based on customers’ requirements. The main limitations are the lack of storage conditions and holding time constraints. Originality/value/contribution – The main contribution is related to developing mathematical models that consider simultaneous categorization of products vertically, based on one characteristic, and horizontally, based on another characteristic. Contribution is also related to extending the shelf space allocation theory with the shelf space allocation problem model in relation to four sets of constraints: shelf constraints, product constraints, orientation constraints, and band constraints.

The article presents a proposition of a universal model of knowledge conflict resolving using consensus methods, which can be used in a multi-agent decision support system. Knowledge conflicts often appear, when individual agents generate different solutions of the same problem. It is very difficult for the user – decision-maker to make a good decision because the analysis of solutions generated by agents is very time-consuming and the decision must be made quickly. Moreover, selecting one of the decisions on the basis of the experience of the decision-maker is very risky, because he/she could choose the worst solution. Consensus methods, however, allow to agree, on the basis of the solutions generated by agents, one solution, which is a compromise. As a consequence, reducing the time and decreasing the risk level of the decision taking process, to enable the functioning of the enterprise in more flexible.
