A Cluster-Oriented Bayesian Network Approach for Mixed-Type Event Prediction With Application in Order Logistics

Temporal representation and reasoning for probabilistic events describe temporal causal relationships between events. This has been widely used in several applications to predict events accurately. However, there are two challenges: the occurrence time points of events may have distinct types, distributed randomly or at several fixed time points; only limited historical data are available in some cases. This article presents a mixed-type event prediction algorithm based on a cluster-oriented Bayesian network (BN) model to address the highlighted challenges. The proposed model categorizes events as random events or timing events based on their temporal features. The similarity between events is measured according to event types and features. A clustering algorithm for events is further implemented to help reduce the model size and build a simpler and more accurate BN. The experimental results show that the proposed model significantly improves performance under small data sizes.

Inventory optimization in a green environment with two warehouses

Recently, the environment requires more emphasis on reverse logistics in order to maintain sustainability of the human civilization. The article introduces a sustainable model for reverse logistics that is based on two storage facility. Generally speaking, the essential commodities are considered to be decaying in nature. In this model, finite replenishment rate is considered and managed by the forward as well as reverse supply chain. In the beginning, the remanufactured and newly manufactured products are stored in owned warehouses (OW) that have limited storage space and for the excess amount; suppliers hire a rented warehouses (RW) at a higher holding cost than owning warehouses. The objective of this model is to obtain the optimal production and remanufacturing strategies to minimize the total relevant costs of the system. The paper concludes with an illustration of numerical data and a sensitivity analysis. Based on the results, the practitioners are advised to reduce the cycle length if the production rate is relevantly high. Thus it will reduce the holding cost, eventually the total cost of the system.

These systems automate processes, simplify management and increase efficiency. The advantages of implementing information systems are discussed in this article, as well as the problems that companies may face in this process. The inconsistency of the company’s hardware architecture and network with the requirements, as well as the lack of resources, including qualified personnel and finances, are the main problems. Incorrect choice of information system or resistance from employees can also cause problems. Taking into account all these factors and overcoming them is important for the successful implementation of information systems in the field of trade and logistics in order to get all the benefits from the new system.

The EU-MODEX Blended Full-Scale Exercise: A Review

Background/Introduction:Amidst the COVID-19 pandemic, the EU-MODEX exercise had to rethink its logistics in order to promote safer environments for its participants.1Objectives:To describe the Blended EU-MODEX exercise as a method to minimize the risk of COVID-19 contagion and the role of CRIMEDIM during such innovative approach.Method/Description:The first post-COVID-19 EU-MODEX exercise was performed in October 2021. To avoid travels, three EMTs from Austria, Romania, and Estonia virtually deployed in a fictious country hit by a typhoon, operated independently in their own country. The Excon worked remotely from Germany. The interoperability among the EMTs was simulated using an online tool. When a patient, simulated by a local role player, needed a transfer from the EMT1 in Romania or Austria, all clinical information were shared online and a new role player was prepared with that information to continue the simulation in Estonia. CRIMEDIM personnel located at each EMT were tasked to ensure the consistency and the quality of all the clinical cases, matching the clinical information of the incoming patient with the new role player, especially regarding the treatment received and the makeup instruction.Results/Outcomes:During the exercise, 425 clinical cases were played by the three EMTs. The exercise lasted for 60 hours and provided unique challenges due to its blended nature. No COVID-19 outbreaks were registered following the exercise.Conclusion:The experience of the Blended EU-MODEX exercise showed the potentiality of the virtual simulation environment as an effective alternative to avoid secondary contagion as well as reduce costs.

Freight Demand Distribution in a Suburban Area: Calibration of an Acquisition Model with Floating Car Data

The paper deals with the interaction between freight flows, land use, and economy of a suburban area. In urban freight distribution, the process of freight acquisition of commercial establishments represents a crucial element. Therefore, it is necessary to plan city logistics in order to reduce the negative externalities generated by freight transport without depressing the economic and social vitality. In order to estimate and evaluate the performance and impacts generated by urban freight distribution, Transport System Models (TSMs) play an important role in reproducing and forecasting the process of distribution of final products to retailers and consumers. In recent years, Information and Communication Technologies (ICTs) have made new sources of data in great amounts available at lower costs than data provided from traditional surveys. Among the different data sources, Floating Car Data (FCD), obtained through GPS trackers installed on board the vehicles, offer partial insights into the examined process with lower cost and provide continuous information in space and time. In order to obtain reliable results, it is necessary to combine TSMs and ICTs as observed data could feed Transport System Models and could allow their calibration and therefore their application in real cases. In the above context, the paper deals with TSMs related to estimating urban freight demand flows. The work carried out concerns the specification-calibration-validation of a freight zonal acquisition model by means of FCD related to interzonal trips of commercial vehicles inside the Locride area (Reggio Calabria, Italy). The obtained models, estimated from FCD, could support the a priori evaluation of city logistics measures. The results are more important considering that they are obtained in an area with a lack of transport monitoring technologies. They could be adopted in other similar areas and confirm that adequate planning of city logistics determines advantages for environmental, social, and economic sustainability.

Forecasting new product demand using machine learning

The problem of predicting demand for a new product based on its characteristics and description is critical for various industrial enterprises, wholesale and retail trade and, especially, for modern highly competitive sector of air transportation, since solving this problem will optimize production, management and logistics in order to maximize profits and minimize costs. Classic demand forecasting methods assume the availability of sales data for a certain historical period, which is obviously not the case when concerning a new product. Most research papers are limited either to a specific category of goods or use sophisticated marketing methods. This paper proposes the use of machine learning methods. We used data about new product demand from the Ozon online store. The input data of the algorithm are characteristics such as the price, name, category and text description of the product. To solve the regression problem, various implementations of the gradient boosting algorithm were used, such as XGBoost, Light GBM, Cat Boost. The forecast accuracy is now about 4.00. The proposed system can be used both independently and as part of another more complex system.

Redirected entanglements in the digital supply chain

ABSTRACT The supply chain is not just a metaphor for the production of the modern world, it is the very means through which that world is made material. Through the careful coordination of bodies and materials, it delivers the glut of goods necessary for daily life – even as it ties that life to human rights abuses, violent regimes of extraction, and environmental devastation at unprecedented scales. But while software has long been part of every supply chain, the supply chain is, itself, part of every bit of software. Developers speak of digital production in the language of logistics. They write about algorithms as frequently as distribution networks, worry about just-in-time production as much as engineering, and decorate their tools with illustrations copied from shipping companies or factories. The design of data is thought of the same way as the objects that will access it. This article interrogates the emergence of the supply chain, and the logistical modes of operation it entails, as metaphor for managing the digital distribution of data – adapting approaches from the critical study of logistics in order to re-incorporate the political, social, and environmental attachments that ‘digital supply chains’ attempt to obfuscate. To this end, it considers discourses around power and cultural politics that mirror critiques of traditional logistical infrastructures. Instead of conflict minerals, for example, conflict domains; in place of security concerns around cargo containers, data containers; rather than workers on the factory floor, labourers in a digital network of ‘sweatshops.’ These comparisons reveal differences between traditional supply chains and their digital counterparts – the most troubling of which is their infrastructural instability. With components that can be replaced while retaining their essential shape, those who depend on digital platforms can find themselves open to all sorts of redirected entanglements.

MEASURING TRANSOPRT EFFECTIVENESS WITHIN A SUPPLY CHAIN APPROACH

In an economic context strongly characterized by the amplication of transactions, translated by a very increased competition, transport becomes a vital factor of competitiveness since it represents an important component of the cost price of products as well as it allows processes integration between the different logistics actors. Adopting best practices in terms of transportation management by companies seems to be a strategic factor for competitiveness. The purpose of this study is to assess the maturity of transport practices using an SC auditing. This audit is illustrated by the application of the ASLOG standards in an Algerian SME operating in the food sector. The ASLOG model allows to highlight all the strengths and weaknesses of transport logistics in order to be able to set up and follow a progress plan that consolidates the strengths and improves the weaknesses.

Order logistics based on collaborative filtering

Modern approaches to the organization and management of logistics operators include issues directly related to the forecasting of the dynamics of the processes of the company under study, as well as the development of recommendations for further functioning in the market of goods and services. Services integrated into the order and delivery logistics system are an integral part of it and accompany the flow processes throughout the supply chain. Nowadays, the complex of information technologies, communications and technological solutions allows implementing the most daring offers of logistics companies. Innovative solutions developed using information technologies develop the complex “design-practical implementation” in logistics systems and form a digital space for managing material flows. The calculation of the forecast values of the indicators that characterize the order requires research from the point of view of taking into account the already known preferences of customers. We are talking about recommendation systems that offer to form a package of services in the delivery and assembly of a batch of orders based on the established preferences of other customers and users of the services. The well-known preferences of customers when accessing logistics services form the basis for developing recommendations that are close to them. The obtained data of forecasts of the state of the system under study should provide an opportunity to develop an individual package of solutions, based on the already known preferences of other users. The key value is the information that is used in this model to build forecasts. The practice of finding solutions in the management of order procedures in logistics is an analysis of the key problems and “problem points” that affect the overall performance indicator, taking into account the geography of transport systems, established trade practice, the characteristics of the markets studied and the location of each, specifically selected company.

The Innovative Design of the Fire-Fighting Adapter for Forest Machinery

The presented article presents an innovative solution of a fire-fighting adapter based on the basic hypothesis: to provide sufficient technical support in difficult terrain conditions for water transport logistics in order to quickly prevent the spread and destruction of forest fire. At present, when forest fires begin, it is often quite complicated to provide sufficient technical support for the quick prevention and elimination of fires. This fact is largely eliminated by the designed fire-fighting adapter. The mentioned fire-fighting adapter can be used as a fire-fighting mobile device with a base machine of a forest wheeled skidder (LKT), part of the long-distance transport of water in difficult terrain (lake system), a water tank in difficult terrain with the possibility of filling the Bambi bag with a helicopter, part of the long-distance transport of water in the case of a difficult water source without a forest access road network, and a mobile device for emergency transportation of materials in difficult terrain. In addition to the use for fighting forest fires, the fire adapter can also be used to provide for transport of water for forest nurseries (irrigation), freshly planted areas in the event of prolonged drought, the filling of watering-places for forest animals and filling puddles in the dry season. When designing the supporting frame, we used and imitated the evolutionary approach of nature in the form of generative design. The presented paper deals with the use of modern composite materials in the design of superstructures for base machines, which gradually acquire meaning. The main reason for the increasing use of fiberglass is to achieve higher strength and safer weight reduction. This adapter is designed for forest wheel tractors that reach 40% slope availability, are able to work on the stand area, overcome obstacles and are available in sufficient quantities in all Slovak forest areas.

Research status of automation of logistics transport and distribution processes

An analysis of the performance of modern companies has revealed a trend of active investment in innovation, especially in such a dynamic field as logistics in order to optimize supply chains. The article proves the need for a systematic approach to innovative measures in the transportation and distribution system based on the analysis of foreign experience. The dynamism of logistics processes complicates the process of control and forecasting of enterprises. The logistics trend of DHL, which regularly publishes a key tool for the global logistics community, is a radar of logistics trends that reflects the development of society, business and technology. Two major trends are analyzed: 1) social and business and 2) technological. To solve this problem, the process of digitization and the willingness of companies to work online with the help of e-commerce technology have been proposed. Two components of modern innovative business models that enable a business to be competitive and efficient are analyzed: the sharing economy and the marketplace in the logistics services market. It is determined that the main resources in logistics are material assets (especially warehouses and vehicles), labor and time. It is established that transport exchanges are actively developing in the Ukrainian market, where logisticians can choose vehicles, but there are no sites where one can simply choose a warehouse on demand (as a service). There are no tools in the Ukrainian market for quick search and safe rent of warehouses for different types of products. Searching for a warehouse is a complicated and lengthy procedure for the following reasons: the lack of a warehouse database in one source and the complexity of comparing warehouses (search on OLX.ua or through a local or international broker, or on the recommendation of acquaintances), the risks of renting warehouses from unverified agents / owners, the procedure for selecting and concluding warehouse lease agreements, the need for warehouses under peak load, continued. Therefore, in 2019, a new Ware Teka online platform has emerged for finding warehouses for rent or purchase with the largest warehouse real estate base to date, allowing real estate to be rented as soon as possible. The basic features of the Ware Teka online platform are analyzed. It is determined that modern logistics companies in Ukraine have started to implement the system of routing of goods (delivery on points of sale) and receive constant errors, therefore the process of digitization of current deliveries in real time is offered. The Ukrainian market for foreign startups is not interesting for today, and they are not ready to costomize, or costomization will have a very high cost and it is necessary to consider the issues of support after adaptation of the ready solution, to make a premature request about the main problems of adaptation of software products of automation of logistics processes. Support is an important cycle in working with your ISP to be able to refine or modify the software in the future and not be dependent on your provider, so you need to request technical documentation immediately. The importance of automation of logistic processes of transportation and distribution has been proved.

This paper involves the use of the reverse logistics tools to manage reverse flows of grain goods in Ukraine effectively. The object of the study is the reverse logistics. The purpose of the study is the theoretical analysis of reverse logistics in order to implement its tools within agro-industry and assessment of the prospects for that. Methods of the study are the analytical approach and mathematical methods. The reverse supply chain management is a key business strategy of any international manufacturer within such industries as car manufacturing, producing of household appliances and medicine. The reverse logistics is widely used to increase company`s profit and cut down the loses. The authors of this article offer to implement the reverse logistics tools within the agro-industry of Ukraine to efficiently design the reverse supply chain. While analyzing the agricultural businesses in Ukraine, authors found out that using the traditional reverse supply chain can not use the capacity of all the logistics players to the full. The liquidator services are offered in order to maintain value added by the returns of bulk goods. Moreover, considering the sustainability of such a reverse flow we offer to store the returns in the warehouses owned by stevedoring companies located in port of Odessa. In such way the decreasing of gas emissions by 25,2% can be established. The results of the study may be recommended for implementation by every logistics player within the agro-industry of Ukraine. KEYWORDS: REVERSE LOGISTICS, AGRO-INDUSRTY OF UKRAINE, REVERSE FLOW, REVERSE LOGISTICS SUPPLY CHAIN OF BULK GOODS, REVERSE SUPPLY CHAIN INTERMEDIARIES.

Understanding the Brazilian expanded polystyrene supply chain and its reverse logistics towards circular economy

This paper aims to investigate the supply chain and reverse channels of expanded polystyrene packaging connection in Brazil and their roles to discuss the main challenges towards circular economy. In order to achieve this goal, we propose a four-step method, anchored in the literature, technical visits, and interviews with experts in the expanded polystyrene (EPS) industry. First, the EPS supply chain was characterised and mapped, and secondly, the stakeholders and logistics activities in reverse channels were analysed. Third, the Brazilian legislation and chain structure was reviewed to obtain an understanding of how this can influence the activities developed in reverse channels. Fourth, with an analysis of the data collected before, the barriers to implement EPS reverse chain were presented. The main results establish that the EPS can complete one cycle of the circular economy, which is recycling, but products need to be separated and washed. The most significant waste generators are public and private institutions, residences, and retailers. Notable barriers to its recycling are a lack of understanding of the nature of expanded polystyrene recycling by Brazilian people, high transport cost due to material density, and the dispersion of post-consumer expanded polystyrene in several regions of the country linked with the small number of recycling facilities. Finally, this issue could be explored in industries and companies that require their managers to adopt strategies to improve reverse logistics in order to promote the circular economy. The companies’ actions could facilitate a stronger circular supply chain since they could increase recycling efforts, reduce expanded polystyrene waste, and present new business models. The resulting generation of employment would contribute to the quality of life of contemporary society. The findings presented in the paper enable industries to identify and guide the most demanding significant steps and processes, and to shift the reverse chain and expanded polystyrene recycling to ensure that they operate more efficiently.
