The cruise market has developed rapidly in recent years. The opulence of the cruise market has also augmented the demand for the cruise construction industry. Cruise ship construction is a huge and intricate heavy industry that can cause serious environmental problems. Therefore, optimal use of advanced logistics systems, to meet the demands at the lowest possible cost and unnecessary waste, has become a key issue. This paper developed two typical inbound logistics system modes based on JIT (Just In Time)-logistics policy and formulated two single-objective nonlinear models to simultaneously determine the ordering strategy under the inbound logistics system and the optimal selection strategy of two typical inbound logistics modes. Numerical experiments depicted the variations of optimal inbound logistics mode over three different kinds of cruise parts. These two models could provide insights in making inbound logistics decisions, and serve as a reference in the mass customization logistics service for cruise ship construction to control costs, which is helpful for promoting the sustainability of the cruise market.

Inbound Logistics

This article introduces a method and a software-tool for comparing inbound logistics systems in respect of energy consumption. In the field of green logistics numerous methods are already existing, but mostly they focus either on the evaluation of the energy consumption of single logistics components or the improvement of the energy efficiency of logistics processes. There is no hands-on solution which can be used in the rough planning phase of logistics projects to evaluate and compare whole system configurations. With the new method we try to fill this gap by integrating existing methods to a holistic approach. It comprises three steps: “identification”, “quantification” and “aggregation and comparison”. In the identification step every system variant will be divided into subsystems and components by using a hierarchical representation. Quantification means to determine the energy consumption of every component by using physical models or reference values. In the last step the resulting energy values will be summed up to an overall figure which can be used to compare multiple system variants. The Sofware-Tool E|stimate is for the part automation of the calculation method. It comprises a component for transport logistics, one for intralogistics and one for the analysis of the aggregated consumption. In summary, the new method and software-tool enables practitioners to compare inbound logistics system variants quickly with sufficient precision. Because of its ease of application, it contributes to implement the concept of sustainability in daily business.

Cost rationalization has become imperative in every economic system in order to create adequate foundations for its efficient and sustainable management. Competitiveness in the global market is extremely high and it is challenging to manage business and logistics systems, especially in regards to financial parameters. The presence of inventories is inevitability in every logistics system, and it tends to create adequate policies for their efficient and sustainable management. In order to be able to do this, it is necessary to determine which products represent the largest percentage share in the value of procurement, and which are the most represented quantitatively. In this paper, the warehouse of construction material that represents the wholesale system is considered. Taking into account that it is wholesale, it is necessary to determine what the procurement costs are and what the demand is for certain products. The grouping of products into three categories A, B and C was performed, after which it is necessary to identify appropriate suppliers for each category in order to rationalize procurement costs. Financial, logistical and quality parameters are taken into account. The FUCOM method has been used to determine the significance of these parameters and ARAS method is applied for supplier evaluation and selection.

The irregularities of evolutionary development, continuous improvement of environmental component into transport and raise many unsolved problem in the fields of transport in logistics systems and material flows management. The city parameters analyses had highlighted connections with transport services technology. Also the distribution stage of the logistic chain, which consists of following market participants: incoming material flow, retailers and Transportation Company (carrier) in different cities has been considered. Transportation service is made by road transport. The paper compares results of transportation servicing in different cities and logistic chains with same technology. As performance indicator net present value has been used. Existing criteria for evaluating the effectiveness of distribution of material flows does not sufficiently take into account the time value of money and possible options for investment, so when estimating the performance of servicing of business investment indicators should be used. Paper should elucidate the impact of cities on the transport service efficacy. Practical suggestions on logistics system functioning and transportation service of retailers in urban area have been proposed. Obtained results discovered overall impact of city’s parameters (density of streets and roads network’ irregularity factor; automobilizationlevel; urban square; scheme of road network; city radius) on logistics according to model which include more than 50 parameters and allows finding regularities of changing logistics efficiency on them.

Decision-making in complex logistics systems involves high risks and associated impacts. A way to forecast the impacts of these decisions is through the use of systems simulation projects, where the systematic impacts of the parameters can be visualized. This study presents a project based on Discrete-Event Simulation (DES) that analyses Brazilian soybean export logistics from producing regions to main international customers. The strategic analysis of a global logistics system using DES is a particularity of this study. At the conception stage, the conceptual modelling was made using IDEF-SIM (Integrated Definition Methods – Simulation) method, which allowed a better abstraction of reality and more accurate model implementation. The experimental analysis took place through the construction of 39 scenarios with specific characteristics that verified system behaviours through proposed changes. The analyses and decisions are based on costs. The simulations indicated the necessity for: a) an integrated management between the systems agents; b) the development of internal transportation infrastructure, especially railways and waterways, to increase competitiveness of Brazilian soybeans in the international market.

Transportation is a key logistics function, which determines the dynamic nature of material flows in logistics systems. At the same time, transportation is a source of uncertainty of logistics operations performance in the supply chain. Obviously, the development of a new approach for evaluation of the duration of delivery “Just-In-Time” (JIT) will improve the efficiency of supply chains in accordance with one of the major criteria, namely customer satisfaction. One of the basic approaches to make effective management decisions in transportation and other logistic operations is the JIT concept. In the majority of examined sources the JIT concept is described on the verbal level without any usage of calculation dependences. The paper is devoted to the formation of analytical and simulation models, which allow obtaining the probabilistic evaluation of the implementation of unimodal and multimodal international transportation JIT. The first model where the order of the operations implementation does not affect final result is formed on the basis of the probability theory: distribution laws composition, theorems of numerical characteristics of random variables, formula of complete probability. The second model accounts the impact of operations implementation order in transportation and their interconnection and is based on the simulation (the method of statistic experiments) and shown as a corresponding algorithm, which allows to consider different limitations (technical, organizational and so on). Considered analytical dependences give the possibility to obtain the necessary estimations of the transport operations implementation according to JIT: mean transportation time, delivery implementation probability by the set moment or the delivery time with the set probability. To carry out some comparative calculations and clarify the algorithm, two international routes have been chosen: the first one is a unimodal road transportation, the second one is a multimodal transportation (road and marine transport). All the data, which is necessary for calculation has been collected on the basis of official information (in particular, the data of tachograph, special questionnaires filled in by the drivers, the survey results of the managers). For unimodal transportations analytical dependences and modelling results give close results. For the combined multimodal transportations taking into account various limitations the preference must be given to the simulation. The modelled indexes take into consideration their intercommunication and definitely estimate the supply chains reliability, and this allows decreasing the uncertainty of the logistic system.

Abstract The purpose of this article is to present the new challenges faced by the automotive industry and specifically by the steering wheel producers in terms of product design changes, process changes and the solution to solve them, the concept of TTM - Total Traceability Management. The article presents the traceability solution as a proved solution for managing JIS (Just in Sequency) & JIT (Just in Time) manufacturing concepts in terms of customer demand sequence attainment, process sequence attainment, and technical test verifications. The research is based on case studies deployed in production facilities, in the companies TRW and Key Safety Systems. Both entities are steering wheel producers with JIS&JIT conditioned production systems and are also using latest technology in synchronizing the traceability communication with various cars producers (Porsche, BMW, Daimler, etc.). This concept of manufacturing and delivery of the products to the famous automotive companies is crucial for the supplier including the base of business, because the entire work in this domain is completely automatic by robots. That means: all the final products (cars end others), including the components from different suppliers, also the technology of assembling, it need to be adapted in order to be performed by robots. The components as steering wheels, and many others, arrive at the assembling line at OEMs (Original Equipment Manufacturing) facilities and the robots work on directly the buffers with these components in order to ensure the continuous assembling process in the condition of total flexibility and without errors.

The paper reveals the important characteristics of methodological approaches to assessing the effectiveness of logistics systems. Peculiarities of functioning of logistics systems of pharmacy networks are characterized. Based on the acquaintance with the scientific works of the founders on this issue, approaches to assessing the effectiveness of the logistics system are systematized. A system of evaluation indicators for each component of the logistics system is proposed. The logistics system of the business entity, and this fully applies to the logistics system of pharmacy networks, is not in a permanent state. Dynamic changes in the system are due to the influence of macro-environmental factors and changes in the internal nature, which pose the task of developing the system to ensure its adequacy to new conditions. It is the development of the system is the basis for improving the efficiency of its operation and the ability to achieve goals through the solution of a certain range of tasks. In such conditions, the study of the development of the logistics system of the pharmacy network deserves special attention. Existing approaches to assessing the development of the logistics system do not exclude, but complement each other, creating a methodological basis for the formation of effective management decisions on logistics management of the business entity. As a result of research of scientific works of domestic and foreign scientists on a problem of a choice and formation of indicators of an estimation of efficiency of logistic systems, we proposed a system of evaluation indicators for each component of the logistics system. In this case, in our opinion, such a system should include not only indicators that characterize the efficiency of the functional components of the logistics system of the pharmacy network (supply, production, transportation, warehousing, sales), but also indicators of efficiency subsystems, namely organizational and management, infrastructure and resource subsystems. This system approach will allow to take into account the impact of all components of the logistics system of the pharmacy network on the efficiency of its operation.

The article considers the research of the process of supply of resources for construction taking into account the logistical needs of reversible logistics. The result will be the gradual formation of logistics systems in the construction industry, which should lead to the formation of a single logistics system of the construction industry. This will create a set of integration effects. First of all, to identify the main objectives of the logistics system in the construction industry as a whole, it is necessary to determine the basic economic parameters of each system participant, decompose the logistics system, and then determine the integrated economic characteristics of its activities. It is noted that the current level of logistics development and the growing specialization of its individual functional areas require a focus on the whole chain of causal relationships. Most logistics systems are focused on one direction of movement of inventory - from producer to end consumer. As a result, the process of decomposition of the logistics system of the construction industry according to the main economic parameters of operation was created. The current trends in logistics development that emerged during the pandemic have been identified. The general and basic concepts of waste management of construction companies are considered. The scheme of the waste management hierarchy is given. It is established that the main principles of economic regulation in the construction industry of waste management are to reduce the amount of waste and involve them in economic turnover; payment for waste disposal; economic incentives in the field of waste management. The main problems of reverse logistics facing the business and the possibility of solving them through the introduction of a system of reverse logistics or recycling are identified. In conclusion, the introduction of integrated logistics systems was proposed, which is especially effective in large construction projects located in urban centers, where massive material flows must be managed.
