Opis:
In recent years, Reverse Logistics (RL) has become a field of importance for all organizations due to growing environmental concerns, legislation, corporate social responsibility and sustainable competitiveness. In Reverse logistics, the used or returned products are collected after their acquisition and inspected for sorting into the different categories. The next step is to disposition them for repair, remanufacturing, recycling, reuse or final disposal. Manufacturers may adopt reverse logistics by choice or by force, but they have to decide whether performing the activities themselves or outsourcing to a third party (Martin et al., 2010). Lourenço et al., (2003) described three main areas of improvement within the RL process. Firstly, companies can reduce the level of returns through the analysis of their causes. Secondly, they can work on the improvement of the return’s process and, thirdly, they can create value from the returns. This paper considers the multistage reverse Logistics Network Problem (mrLNP) proposed by Lee et al., (2008). With minimizing the total of costs to reverse logistics shipping cost. We will demonstrate the mrLNP model will be formulated as a three-stage logistics network model. Since such network design problems belong to the class of NP-hard problems we propose a Simulated Annealing (SA) and simulated annealing with priority (priSA) with special neighborhood search mechanisms to find the near optimal solution consisting of two stages. Computer simulations show the several numerical examples by using, SA, priSA and priGA(Genetic algorithm with priority-based encoding method) and effectiveness of the proposed method.

In the paper authors presented concept of evaluation of complex systems such as logistic companies which operate in competitive environment. Authors also highlighted the importance of the evaluation problem in operational activity, particularly in the properly prepared procedures to be followed, consisted of several stages adapted to currently conducted research. Properly executed evaluation of companies enables customers to take right decisions on contracting services and stimulate the development of those companies. It should be noted that the proposed algorithmic model of assessment may be particularly useful for assessment of complex logistics systems. Characteristics of the respective phases developed procedure allowed to indicate that it is important to select of appropriate criteria and evaluation methods. It was pointed out that particularly useful for assessing of logistics companies are multi-criteria analysis methods, because they allow to examine objects in a holistic manner, taking into consideration various aspects of activities such organizations. For the practical realization of assessment of logistics companies there was proposed Bellinger method, which contains quite transparent procedures. The results obtained from that method are consistent with those carried out by means of other, more complex multi-criteria methods. Also there was presented the problem of selection of weighted factors for the criteria in the context of their impact on the end result of evaluation. It was pointed out that the choice of an appropriate procedure for determining weights depends on the nature of the evaluated problem and form of criteria.

Opis:
The paper presents a certain approach to solving the problem of warehouse locations based on the application of a genetic algorithm. The main objective is to indicate a location of warehouses from among those that already exist, which are most likely to assure the best value of the adopted criterion function, concurrently meeting recipients’ needs. A formal notation was presented of the mathematical model, allowing for the indispensable data, decisionrelated variables of limitations and the criterion function. The problem is to determine the location of warehouses taking into account minimising costs of transport and storage of forwarded cargo between determined facilities within the network. To allow solving the problem related to warehouse location within the logistics network of a manufacturing enterprise the use of a genetic algorithm was proposed. The structure of the algorithm was adapted to the mathematical model. A genetic algorithm was used to determine the volume of cargo stream flows between particular facilities in the network. To form a genetic algorithm it is advisable to define the chromosome structure, the adaptation function, cross-linking process and mutation. The location problem is solved in such a way that if for any day within the analysed period flows take place from a given warehouse or to a given warehouse, such a logistics facility should constitute an element of the target logistics network. If there are no such flows, no warehouse is necessary in the given location.

Opis:
The paper presents an approach to the assessment of the location of facilities in the warehouse logistics network with the efficiency of its operations. Determination of efficiency of complex systems of this type should take into account wide range of issues. The system efficiency results on the one hand from the efficiency of its action and on the other hand from the ability to use available system elements to achieve the objectives. Efficiency is a main criterion to the evaluation of the activity both at the level of the whole system, as well as in its subsystems or components. Most often, it refers to the principle of rational management formulated in two variants: performance (maximization effect) and economical (minimizing effort). The article poses the thesis that based on studies of speed and reliability of execution of tasks it is possible to assess the potential locations of warehouse facilities in the studied logistics network. Were also presented factors affecting the efficiency of the functioning of individual cells of the logistics network. Was pointed to the technical, economic, organizational and reliability aspects affecting the efficiency and reliability of the logistics network in terms of both supply and distribution. It was also presented a modular block diagram of an assessment method for localizing logistics facilities in the logistics network.

Opis:
The paper presents an approach to the logistics service for companies by warehouse facilities with different configurations in the logistics network. Through the warehouses it is possible to combine internal logistics functions such as ordering, unloading, product receptions, confectioning, order picking. The occurrence of warehouse facilities and suitable strategy also affects the volume of stocks, because they allow for combine reserves and compensates for fluctuations in demand. Optimal control of the amount of inventory reduces the demand for warehouse space and associates storage costs. The appropriate configuration of the warehouse facilities in the logistics network is therefore critical for effective logistics service of manufacturing companies. In such logistics network, individual subsystems are related to each other by different types of relation. From these interconnections result logistic tasks performed by company logistics system. Their implementation is caused both externally and internally, wherein the first considerations arise from the environment, the other from production. External logistic task is the boundary conditions for storage process in manufacturing company. The configuration of storage process determines the execution of internal logistics tasks for the company. The article also presents the logistics network configuration taking into account both direct and indirect services.

Opis:
The paper deals with the concept of centralized demand forecasting and logistical coordination in distribution networks. The aim of the paper is to relate the results provided by the forecasting tools to the basic aspects of logistical coordination. The case of 29 distribution networks in which a logistics operator (3PL) operates and provides contract logistics services to a manufacturing company is analysed. The paper partially confirms the hypothesis of better testability of forecasts based on machine learning algorithms and artificial neural networks for demand planning by the logistics operator to the manufacturer in the framework of logistics coordination in the distribution network. These algorithms perform better for networks with high specificity of flows and food networks. Traditional algorithms, on the other hand, have their better share in creating forecasts for more standard distribution networks. Addi tionally, the second hypothesis regarding the positive influence of modern technological solutions (such as the use of cloud technologies, EDI and flow tracking standards) was confirmed. Additionally, a number of factors that did not have a direct impact on forecasting errors were detailed.
