Abstract The TTM (Total Traceability Management) is becoming a mandatory process requested by all OEMs (Original Equipment Manufacturing) as a system to be deployed by the relevant suppliers. Process parameters from the machines are gathered by the TTM software and based on a defined algorithm the product is receiving new statuses, as physical and software characteristics. Given the high complexity of the current process flows, the highly automated lines and cells, the increased amount of process parameters, the necessity of synchronizing various production steps, it is needed that a simulation process to be done in advance of the full process deployment. The paper work reviews both the mathematical apparatus that underlies the simulation, and one of the various available simulation programs in academia. It is used one of the most usual software for simulation SIMQuick which is based on statistical methodologies. SIMQuick performs a virtual simulation of the process being used in various areas of activity including production in automotive, automation, supply chain processes and services, providing the valuable data for the behavior of the process and providing the premises for layout, flows, and resources improvements. The supply chain software ERP requirements with TTM technical inputs and outputs are the data pillars for the simulation which are presented as a result of the research.

Additive manufacturing is one of the technologies that is beginning to be used in new fields of parts production, but it is also a technology that is constantly evolving, due to the advances made by researchers and printing equipment. The paper presents how, by using the simulation process, the geometry of the 3D printed structures from PLA and PLA-Glass was optimized at the bending stress. The optimization aimed to reduce the consumption of filament (material) simultaneously with an increase in the bending resistance. In addition, this paper demonstrates that the simulation process can only be applied with good results to 3D printed structures when their mechanical properties are known. The inconsistency of printing process parameters makes the 3D printed structures not homogeneous and, consequently, the occurrence of errors between the test results and those of simulations become natural and acceptable. The mechanical properties depend on the values of the printing process parameters and the printing equipment because, in the case of 3D printing, it is necessary for each combination of parameters to determine their mechanical properties through specific tests.

Whereas e-government used to be focused mainly on digitalizing documents, the attention is currently shifting to the question how the main governmental functions service, care and control can be realized in the best way in an information age. In this respect, e-customs is a case in point. Worldwide Customs is transforming from the labor intensive paper work it used to be for ages to “e-customs,” where international trade is facilitated by fully exploiting the current global digital infrastructure. As a consequence, a shift in the distribution of responsibilities can be observed (so-called horizontal supervision). The authors show how this shift can be leveraged by further technical developments grouped under the label of Service-Oriented Auditing (innovative auditing services based on the Service-Oriented Architecture). A particular challenge is coordination. There is a need for better coordination of the numerous governmental and supply chain controls. They explore different coordination mechanisms to support this development.

The article deals with the problems of perishable goods handling process at Russian airports on delivery in international supply chains (ISC). The investigation was carried out on the basis of operational analysis. The initial stage of the study, which was performed applying statistical analysis, revealed that the major category of perishable goods which establish air transportation demand into Russia is the fresh exotic fruits. The investigation was performed taking the mango supply chain as an example, due to its non-standard thermal and storage requirements. The second stage resulted in the perishable goods airport handling quality criteria set formation: the number of mandatory cargo while handling operations, the required time for these operations, the amount of paper work, the number of multi-temperature chambers at the airport and their area, ULD temperature storage system availability. The study revealed that about 90% of perishable goods, which are imported to Russia, are handled at the airports of Moscow aviation hub because other airports in Russia lack the temperature storage facilities infrastructure. This restriction raises the price of perishable goods logistics on the territory of the country considerably as well as reduces their quality. Four international airports of strategic importance outside the boarders of the central federal district which have the potential of forming central hubs for perishable goods handling as well as processing of transit and transfer flows were chosen in the context of this study. Among them are the airports of Novosibirsk, Vladivostok, Yekaterinburg and Krasnoyarsk. The airports of Moscow aviation hub were offered specialization on the subject of perishable goods export-import flow handling. The materials received from airlines, major cargo terminals at Russian airports, transport companies, specialized international air transport enterprises and logistics associations were exploited as the data for this study. The research registered that the deterrence to the speed of supply chain operation is the time of cargo ground service at Russian airports which considerably exceeds the cargo ground service time in the exporting country. The delays are connected with the poor development of perishable goods handling cargo terminals and also with loads of paper work because the system of electronic workflow and automated checking of markings doesn’t exist. The model of electronic workflow in the International Supply Chain which utilizes pre-flight and pre-loading preliminary information about the cargo was offered. Block Chain system for checking the correct presentation of documents at all stages of the supply chain was introduced which reduces the total time of cargo ground handling process.

Identifying the process variables that are important to ensuring the production of high quality ingots intended to make railway wheels and axles can be done through costly experimentation, or by numerical simulations. Using MAGMASOFT® software, we created a base model. The base model was validated in three different ways, using results from production to compare against the simulation. Process parameters were then varied to determine if the changes were beneficial or detrimental to conditions such as porosity, pipe and segregation.
