Opis:
Two approaches to modeling microsatellite DNA repeats are considered. The former is an infinite dimensional system based on the theory of branching random walks which dynamic properties are characterized using Laplace transforms and Laplace asymptotic techniques. The latter is an n-dimensional approximation where microsatellite DNA repeats model is the example of a chain system. Both models were the subject of many numerical calculations using the MATLAB software. The results allow us to evaluate the asymptotic behavior and determine the effect of the system parameters on the run of the solution and the state variables.

Opis:
Consensus methods allow to resolve the knowledge conflicts, among other things, in supply chain management systems. The purpose of the article is to elaborate the distance function between the variants generated by the system SCM. This is one of the stages of the consensus determining process. The first part of the article presents a characteristic of knowledge conflicts, consensus methods and a definition of the structure of the variant. Next, the formal definition of distance function was elaborated. This definition is necessary in order to elaborate the algorithms of consensus determining.

Opis:
The purpose of article is to elaborate a consensus determination algorithm in supply chain management support systems, which may lead to achieving a greater flexibility and effectiveness of such systems. Using consensus methods in resolving the conflict of knowledge, in other words, determining a variant to be then presented to the user, based on the variants proposed by the system, may lead to shortening the variant determination time and to reducing the risk of selecting the worst variant. As a consequence, supply chain management might become more dynamic, which obviously influences the effectiveness of the operation of particular organizations and the entire supply chain. The originality is using consensus method to resolve knowledge conflicts in SCM systems to help decision-maker to take decision earning satisfy benefits.

Opis:
Contemporary variability of the environment and market dynamics force enterprises to optimize operations in the supply chain. Advanced IT systems such as the Advanced Planning System are a powerful tool that supports many areas in supply chain management. An efficient supply chain is a key element in gaining a competitive advantage in the market. Therefore, the foundation of the material and information flow regulation in manufacturing enterprises is the efficient exchange of information with both the internal and external environment of the organization. The article presents the optimization process of complex operations taking place in the supply chain by implementing the Advanced Planning System in the examined enterprise. It also enumerates significant benefits resulting from the implementation.

Opis:
Information flows in the logistics and their volume become the starting point for considerations on the Logistics Information System - LIS. In order to select the most important information from the decision-correctness point of view, with the highest merit and in short time, appropriate measures and information techniques should be applied. Only computer techniques can handle with such an enormous amount of data and process them into valuable and useful information. The Logistics Information System is based on the broadly recognised ICT infrastructure, which constitutes the basis for application of further technical solutions. The popular document exchange technique is EDI (Electronic Data Interchange). EDI, as an inter-organizational system, ensures data and information transfer between companies, when pursuing the goals of logistics activity. With this technique, information is collected and transferred almost at every supply chain link.

Opis:
The research problem described in the paper originates from the lack of adequate force protection of tactical level logistic units supporting forces in battle. The author tries to prove the necessity of the application of unmanned aerial vehicles (UAV) in order to ensure security of tactical level supply chains. The new technologies may be an innovative and perspective solution for the problem of the absence of force protection structures in logistic units. The author considers the use of UAVs for observation, reconnaissance and active force protection of logistic points and logistic units supporting tactical level forces. The problem is to choose the correct UAV type and to organise the unmanned autonomous systems (UAS) defined as electromechanical systems with no human operator on board, capable of performing operations in airspace.

This paper presents a continuation of the projects [5, 6] dealing with the novel concepts of evacuating people from large passenger ships. A novel integrated drive and control system for chain lift with lifeboats fastened on it as well as for stern port- ramp, is presented. Additional novel elements is the application of the stern port - ramp fitted with a buoyancy element, and its increased capability of automatic adjusting its operational deflection in the case of a large forward trim of ship. It increases safety and comfort of evacuation in the difficult conditions, but to obtain it a more complex drive and control system has been required to be designed.

Purpose: This paper aims to check the contribution of Logistics Information Systems - LIS to supply chain optimization in the steel industry group of Bachir Rachid. This group that owns eight independent companies and numerous points of sale and warehouses, has to be connected by such advanced systems to ensure effectiveness and profitability. Methodology: A questionnaire was distributed among a group of employees, and the collected data was later analyzed by SPSS 25 and complemented by further structured and unstructured interviews. We have realized an analysis of variance to evaluate the impact of LIS on logistics activities, supply chain management, and integration as well as optimization. The test of Kruskal-Wallis H was chosen due to the non-linearity of the data. Results: This work proves that Logistics Information Systems contribute to the performance of logistics activities, supply chain integration, and supply chain optimization through the enhancement of the efficiency of supply chain management and by the reduction of supply chain costs. The theoretical contribution: The contribution made to the theory of logistics and supply chain management lies in confirming previous findings on the contribution of LIS to logistics and supply chain optimization in Algeria, and more specifically, in the steel industry.

Opis:
The paper introduces a stochastic model for a class of population-based global optimization meta-heuristics, that generalizes existing models in the following ways. First of all, an individual becomes an active software agent characterized by the constant genotype and the meme that may change during the optimization process. Second, the model embraces the asynchronous processing of agent’s actions. Third, we consider a vast variety of possible actions that include the conventional mixing operations (e.g. mutation, cloning, crossover) as well as migrations among demes and local optimization methods. Despite the fact that the model fits many popular algorithms and strategies (e.g. genetic algorithms with tournament selection) it is mainly devoted to study memetic algorithms. The model is composed of two parts: EMAS architecture (data structures and management strategies) allowing to define the space of states and the framework for stochastic agent actions and the stationary Markov chain described in terms of this architecture. The probability transition function has been obtained and the Markov kernels for sample actions have been computed. The obtained theoretical results are helpful for studying metaheuristics conforming to the EMAS architecture. The designed synchronization allows the safe, coarse-grained parallel implementation and its effective, sub-optimal scheduling in a distributed computer environment. The proved strong ergodicity of the finite state Markov chain results in the asymptotic stochastic guarantee of success, which in turn imposes the liveness of a studied metaheuristic. The Markov chain delivers the sampling measure at an arbitrary step of computations, which allows further asymptotic studies, e.g. on various kinds of the stochastic convergence.
