ABSTRACT

The current state of management practice is characterized by the presence of a demand to improve the efficiency and effectiveness of logistics processes, on the one hand, and an insufficient level of application of one of the main tools for achieving this goal – optimization modeling, on the other. One of the main reasons of this phenomenon is the lack of a universal basis of the proposed optimization models that does not allow them to be applied widely enough in companies with different business process structures. The aim of the research was to develop a universal, based on the SCOR framework, integrated model for optimizing the logistics service of an enterprise. During the research process, the overview of the developed models for logistics service optimization, the analysis of the limitations of the logistics system optimization models, the adaptation of the map of SCOR process metrics have been carried out; the influence diagram of the optimization model components has been developed; the models of cost optimization and logistics service optimization have been combined into a single integrated optimization model; an algorithm for the optimal solution search has been elaborated; the implementation of the model and algorithm as a program for the solution search has been introduced. As a result, the integrated optimization model based on the components of the SCOR model has been developed, combining the cost and service level optimization models, using the outputs of one model as inputs for another when searching for an optimal solution. Building the optimization model on the basis of the SCOR model components provides universal character of its application, taking into account the set of costs, arising in a logistics system, including indirect ones, and the set of metrics of logistics service reflects the links between functional departments, the ability to maintain a level of total costs at the efficiency frontier, achieving the goal of the profit maximization at the same time, provides a link between the tactical and operational levels of decision-making, which together leads to an increase in the reasonableness and quality of management decisions, and creates prerequisites for the overall optimal functioning of an enterprise logistics system.

ABSTRACT

Tools for the quality evaluation of cold chain as the optimal technology of perishable сargoes delivery raise interest in the sphere of perishable products transportation logistics now. In the conditions of the rapidly changing directions and extent of food products cargo flows, it is extremely important for consignors to be confident in safety and deliveries of their freight in the specified time frame. The effective control and monitoring system of the freight set temperature can be the determining competitiveness parameter for the logistic providers. The complex of indicators of quality of cold chain offered by the German Lloyd gives only the assessment of logistic infrastructure in statics, disregarding features and specifics of separate cargoes transportation and passing of delivery routes certain sites. In the article the evaluation method of the intensity of temperature deviations from the specific freight set mode on separate links of cold chain is offered. The offered tool of the quality evaluation of perishable goods transportation technology allows to reveal problem zones and sites when passing a cargo flow through various links of a delivery chain. Together with the cold chain quality indicators by the German Lloyd the evaluation method of temperature deviations intensity from the set mode can provide a complex quality evaluation of a separate link of Cool Chain. Diagnostics of both compliance of the technological infrastructure elements involved in process of perishable goods transportation to required standards and these elements functioning in direct certain freights delivery processes on certain sites of cold chain is performed.

ABSTRACT

A manufacturing company frequently plays a role of forming unit in a supply chain. The quality of manufacturer’s logistic system administration is an important impact factor for both company’s and supply chain’s performance and competitiveness. This article deals with the topical problem which consists in evaluation of logistic system administration efficiency in a focus company’s supply chain. The methodology for solving this problem, which was developed by the author, is presented. It includes 3 groups of indexes: strategic, which are presented in terms of Balanced Scorecard (BSC); operational, which estimate logistic system administration quality and integrated, which are calculated following changes in crucial for this system (subsystem) indexes’ rate of growth.
The quantitative evaluation of such logistic system’s characteristics, as organization, rhythmicality, synchrony and stability, which are used in the process of logistic system operational management as well as integrated indexes, which are offered by the author, are of academic interest. These indexes allow estimating the impact of the logistic system administration quality on a focus company’s and supply chain’s efficiency.
