Abstract.A technological process is evaluated as a random process and assessed in respective models. The methodology of formalizing technological processes in the terminal and criteria for optimal control and the quality of the technological process are suggested. In addition, models and algorithms for the optimal control of freight clearing technological process are proposed.
The article dwells on the aspects of mobile solutions of public information and transport. The work presents major decision making principles based on object positioning and a system of positioning‐based GSM solutions. The newly developed remote identification systems for transport facilities and goods and passenger transport and their schematic view are presented. The main units of the remote identification system of vehicles and goods embrace: TI portal, TVIM portal, content control system (SMS, GPRS), mobile phone, the unit for stating the geographical position of vehicles and goods. Portals are designed so that the data provided by various systems of observation, such as GSM, GPS, WLAN, wireless internet, etc., can be used there. Portals (TI and TVIM) can also be used for testing, complex evaluation of monitoring functions as well as for providing the data on geographical location of objects, transmitting data to mobile telephones, etc. Purposes and functions of the portals are presented. The article describes the facility of implementing the mobile user concept, changes made in the portal pages to support the mobile users.
In the course of freight transportation its technological process is influenced by lots of random factors. The classification of random factors in the whole hierarchical structure of the technological transportation process is presented together with the assessment of the dependence of separate random factors. Statistical information on freight and transport flows is renewed and replenished in the course of time. With the growth of information amount the cost of its storage increases as well. Therefore the relevant algorithms for obtaining required statistical assessment with the least statistical information are presented in the article. It is deduced that in the modelling of transport networks and freights as well as the flows of transport means in them, it is analytically proper to describe random factors by the non-parametric assessment.
A model for distribution of warehouses in the commercial network in optimising transportation of goods has been established. The target function in the model includes: fixed prices for construction of big and small warehouses; variable prices for transportation of raw materials and goods between warehouses and commercial points. The algorithm was created for optimisation of local roads network between commercial points. As substantiated, if density of distribution of target function values in the zone of extreme is fairly high, the independent random search is sufficiently effective even when comparing it with regular methods.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
