INTRODUCTION In terms of competition, the adaptation to the customers’ interests requires timely response to these requests from carriers. It leads to improving the quality of service, minimizing the order execution time and strict adherence of the delivery schedule. The focus must be on the customer orders execute on process. [6] Delivery of products from producer to consumer "just in time" and "just-in-sequence" at a minimum cost of freight and material resources is the basis of transport logistics. The need to develop and implement the JIT and JIS concepts during transportation has appeared in consequence with the connection of delivery process by a certain time and a certain sequence. After some investigation of applications for the delivery of goods in [8], it was found that the main consumers’ requirement for shipping transportation services is the implementation of the timing and sequence of the order: delivery of goods "just in time", "just-in-sequence". Thus, the process of delivery in compliance with the conditions presented is in the spotlight of logistical management [7]. Currently, different approaches are used to solve problems of management and organization of the transport process with the use of logistic principles [4, 5]. Despite some positive results, the of the transport process planning problems are solved without taking into account all the requirements producible by participants of delivery process. Such logistics concepts like JIT and JIS allow to take into account the customers’ requirements in delivering the goods "just in time" and "in sequence" when scheduling. In Russia, the concepts of JIT and JIS used in transport logistics and distribution. Since May 2003, JSC "Severstal" started to supply metal-roll to the LLC "Caterpillar Tosno" on the principle of JIT, i.e. the customer as needed in a particular material. In addition, in Russia JIT supply system is provided by the company Master-snab, a leading supplier of industrial equipment and the leader in integrated supply in markets of Tver and Moscow regions. The company "EUROSIB-Logistics" offers JIT delivery system for automotive components and large-diameter pipes. In the field of construction of the Russian-Czech construction company «U-Group» offers its services to clients in the design and construction using prefabricated steel structures using JIT [11].Bo Andersson, the president of AvtoVAZ, believes that the introduction of the concepts of JIT and JIS, would reduce the term from the date of delivery of automotive components to be mounted on the car trade; free storage space that can be redeveloped; to reduce over-production, reduce waste and unreasonable traffic. Ultimately, the company can achieve a substantial reduction in the cost of production [12]. IDENTIFICATION OF SUPPLY CHAINS IN TERMS OF JIT AND JIS The consequence of imperfect organization of the delivery process, carelessness of vendors, problems in communication and imperfections of inventory management is the failure of delivery "just in time" and "just-in- GULUSTAN BLACK SEA SCIENTIFIC JOURNAL OF ACADEMIC RESEARCH 32 MULTIDISCIPLINARY JOURNAL Copyright ОАО «ЦКБ «БИБКОМ» & ООО «Aгентство Kнига-Cервис» ISSN: 1987 - 6521, E – ISSN: 2346 – 7541 JANUARY 2016 VOLUME 27 ISSUE 01 Logistics sequence" that can lead to decreased quality of logistics services, the failure of production, loss of goodwill and etc. It is necessary to plan all logistics operations in space and time in order to organize effective delivery. However, before planning logistics activities for the delivery of cargo and schedule, it is necessary to identify the supply chain (SC) on the basis of classification criteria. There are different approaches to the classification of SC. Classification of the supply chains, given in [10] is based on affiliations between participants; in [1] the classification is based on the multiplicity of application to vehicle capacity and types of branches of the system in which they operate; the basis of the classification given in [2,3] is the complexity of behavior of participants in the SC, the SC hierarchy. Thus, the SC can be generally grouped by the following characteristics: by mean for functional areas; by the structure of functional areas; by territorial boundaries. However, the approaches to the classification of the SC mentioned above do not include special features of the transport process of delivery of goods by road, for example, the regularities of transport process, multi-link structure of SC, the intensity of cargo flows in the SC, capacity of SC, etc. According to the studies [8] it is ascertained that supplies can be divided as mono- and polyconsignment. Monoconsignment supplies delivery of cargo which is implemented within request for one consignment. Polyconsignment supply is delivery in which the declared volume of cargo is shipped in several (n, n>1) consignments. For example, according to the request the cargo is to be delivered to consignee. Total volume of cargo is 80 tons, but 20 tons must be delivered until 10.00 am, 30 tons – until 14.00 pm, 30 tons – until 18.00 pm. Thus, the delivery will be implemented in several consignments: First shipment – 20 tons – until 10.00 am; Second shipment – 30 tons – until 14.00 pm; Third shipment – 30 tons – until 18.00 pm. These types of supply can be classified according to the following characteristics of through-passing material flow in accordance with the terms of there quest, see Table 1. Implementation of delivery on the principles of JIT and JIS is possible when there is a schedule of the SC, which takes into account all conditions and restrictions. Existing models and algorithms for scheduling the delivery process of goods in direct SC do not fully correspond with the concepts of JIT and JIS [3].Presently, there is no model or algorithm for scheduling the delivery process of goods in direct SC based on the concepts of JIT and JIS in urban environment. Therefore, there is a necessity for creation of a model and development of the algorithm. THE DESCRIPTION OF MATHEMATICAL MODEL Formulation of the problem of constructing the model is as follows: there is a direct SC with one loading center and one unloading center, the system is running one vehicle (automobile). Daily the goods are delivered within the system on the concept of JIT and JIS. As a result, the time and sequence of delivery for each consignment is different. The assigned task of this paper is to develop a model that will allow schedule in the delivery process of goods by road on the basis of the concepts of JIT, JIS in direct supply chains. Fundamental factors taken into account in the model are time of delivery “on time” and compliance with certain sequence. The main objective of this model is to deliver goods in direct SC in compliance with JIT and JIS concepts. Thus, the model describes the functioning of the SC. The model parameters are deterministic, character of the transport process is discrete, as proved by Professor V.I. Nikolin and the direct SC is linearly ordered structure, the transport scheme in the SC is pendulum route with unloaded reverse hauls. The following designations are stated in the mathematical model: 1.

Condition of compatibility observance for working hours of consigner, consignee and automobile. Working hours of automobile must be more or equal to the beginning of working hours of consigner and consignee and less or equal to the finish of working hours of consigner and consignee. 7. Condition of compatibility observance for time of beginning of the first load of the first consignment and working hours of automobile. Time of beginning of the first load of the first consignment must be less or equal to finish of working hours of automobile and more or equal to beginning of working hours of automobile. 8. Condition of compatibility observance for time of finish of the last un load of the last consignment and working hours of consignee. Time of finish of the last load of the last consignment must be less or equal to finish of working hours of consignee and more or equal to beginning of working hours of consignee. 9. Condition of compatibility observance for time of beginning of delivery of n-th consignment and time of beginning of delivery next consignment n+1 time of beginning of delivery of n-th consignment must be less than time of beginning of delivery next consignment n+1. 10. Time of beginning of i-th load consignment must be less or equal to difference between time of beginning of load i+1andtime of turnaround. It should be noted that the limitation on the quantity of automobiles in the SC, the quantity of loading posts, the quantity of unloading posts, the system’s capacity must be implemented at the stage of forming a delivery schedule, because in the case of not implementing at least one of the limitation simple mentation of the schedule of the SC is obviously impossible. Another calculation model considering mechanisms of transportation and delivery processes in such transportation scheme must be designed. CONCLUSIONS Summarizing the results of the research we can state the following conclusions: 1. The necessity of application logistics principles of JIT and JIS in the practice of planning, organizing and controlling processes of delivery is substantiated. Topicality of development and implementation of the "just in time", "just-in-sequence" concepts in transport logistics is due to the fact that in only in such a system the process of delivery becomes manageable. Such system improves relationship with customers, the market position of the GULUSTAN BLACK SEA SCIENTIFIC JOURNAL OF ACADEMIC RESEARCH 37 MULTIDISCIPLINARY JOURNAL
