Russian mining industry experiences a rapid growth providing an attractive market for suppliers of mining equipment. However, it's a customer-dominated market. The customers set stringent requirements for the initial equipment supply, as well as for the after-sale service and spare parts supply. The manufacturers of mining equipment are thus facing the need to rigorously analyze their supply chain, to develop a reasonable customer service policy and to adjust the supply chain to meet the requirements of the service policy. To fulfill the after-sale maintenance requirements, the manufacturers must stock spare parts within the supply chain and to design inventory control policies. This paper presents an agent-based simulation approach for estimation of the supply chain's key performance indicators and to explore the service - cost trade-off. The conceptual model and the description of its implementation in Anylogic 8.4 software are provided. A case-study of a global mining equipment manufacturer's branch operating in Russia is described. The model is used to estimate the inventory control policy parameters required to meet the target customer service level, to compare make-to-order against make-to-stock supply strategies, as well as to explore the service level - cost trade-off.
Author examines the impact of integrated planning and, spesifically, sales and operations planning (S&OP) on balancing and reconciliation of market requirements and operations capabilities. Two levels of planning – operational and tactical – are taken into consideration, and results of balancing attempts on each of them are compared. An outline of new approach to the evaluation of sales and operations planning impact on business economy is presented.
Although on the surface budgeting is seen as the main process, among the factors of its efficiency in the first place is closely associated with the process of formation of the annual operating plan. Especially, the importance of this process increases with the current trends of the transition from mass production to customization. Thus, the reasonable budgeting will be possible only if we pre-carry out detailed planning of operating activities in the physical units. The question is, what level of aggregation we can afford when planning the operations and is it necessary to make their scheduling on the stage of operational (tactical) management? In this article the approach to structuring activities based on modern organizational techniques is formulated, the methodology of formation of the annual operating plan of the company is proposed, are considered the need and opportunities for scheduling execution of orders at the annual time horizon for the enterprise with a high degree of production diversification in the conditions of orders of varying complexity and duration of execution.
The article deals with the problem of quantitative estimates of the most important for process models of the SCOR type. The urgency of the problem is due to the growing competition in the market of logistics services and the increasing consumer requirements for the quality of logistics services. The original algorithm for integrated assessment of the sustainability of the company's business is considered.
Both restricted development of the economic industrial sector and increase in the number of structural investors require effective management of the material and financial resources of an enterprise in order to reduce its production costs. The proposed work considers optimization models for managing the enterprise’s production and financial activities that make it possible to increase the efficiency of its operation in a dynamic market environment. In addition to static models of the optimal production program selection with limited amount of fixed and working capital that do not consider the impact of the time factor, dynamic models of the production program optimization are proposed. Last type of models calculates the effect of inflation on the company’s marginal revenue. Impact of inflation on both the selling and purchasing price is in the focus of the paper. The method to calculate optimal output under lack of inventory and equipment in the static models is based on linear optimization. Meantime, dynamic models are solved by nonlinear optimization. Using the attributes of piecewise constant functions, nonlinear dynamic models with a vector function as a solution is proposed to be transformed into linear programming models. The optimal solutions found in dynamic models are evaluated for its stability to inflation impact. Application of models with dynamic management of fixed and working capital is shown on the numerical example of the OAO Rot Front chocolate factory (a publicly held company under the laws of the Russian Federation) in the second part of the paper.
The problem of management is formalized for the first time by purchases as a problem of a choice of the best decision at many criteria. Thus some of private criteria allow to consider demanded risk factors. Possibilities of the decision of problems of this kind on the basis of a method of a tree of decisions are illustrated.
For the task of managing contracts in the supply chain in terms of choosing the optimal contract model, the article for the first time presents the procedures of optimization at many criteria. The paper shows that such a format of the model allows to take into account pure risks that can be formalized as private individual criteria. In this case, they can be taken into account in a special format for presenting estimates of particular criteria. As such a format, the article discusses a method of presenting them corresponding to a generalized selection criteria. For this approach, the article presents optimization procedures for choosing the type of contract based on traditional selection methods. The article illustrates that this approach may lead to different solutions for the alternatives that expands the tools for adapting optimization procedures to the preferences of the decision maker. For the first time the paper proves that according to the format of the selection criterion for the geometric mean (and the same for the multiplication criterion), the transition to the format of generalized data does not change the best choice and ranking of alternatives. The appropriate modeling results are presented within the framework of the pure risk concept.
The author considers basic goals of supply logistics for network retailers in view of coordination and integration of different kinds of logistical activities with marketing and sales divisions to achieve corporate goals with optimal resources costs. It is shown that taking into account the conceptual view and aspects of information support, the majority of logistical problems of supply logistics arise in SRM (Supplier Relationship Management). The next step on the way of improving of optimization of supply management in trading companies has become the application of the process approach for purchasing management. This approach has initiated information systems that allow effectively support planning and controlling of supplying processes. One of such systems entering into the class of local software products of purchasing planning support of trading companies (retail networks in particular) is «Open
to Buy» – ОТВ. The author considers ОТВ’s functionality. The provided case studies of retail networks show how the basic target OTB – the optimization of commodity stocks in supply chain of a network retailer and how major divisions of a retailer cooperate: logistics, sales, marketing, finance while formation of the purchasing plan and inventory management to maximize sales profitability.
The structure of a complex of models of interaction of participants is offered at designing and operation of the logistical center (LC), and also variants of modeling of the organizational-administrative decisions defining efficiency of functioning and interaction of counterparts in LC. The algorithm of construction of organizational-administrative model LC is shown. Problems of interorganizational coordination in LC are considered and decisions which allow to eliminate the reasons of occurrence of conflicts are offered. Mechanisms of counterparts LC centralized and decentralized coordination are opened.

The article shows that in the context of severe competition and an increasing expansion of Western firms issues of an effective collaboration of Logistics and Marketing become more and more important for most Russian companies. It is demonstrated that organization of Marketing and Logistics collaboration has changed significantly in many companies lately – from the traditional scheme of functional division of a firm’s fields of activity to general costs optimization and finding the balance of “logistics service costs/quality” in distribution. The author systematically examines spheres of Marketing and Logistics collaboration and provides a detailed characteristics of marketing channels formation strategies with regard to Logistics requirements. Main trends of Logistics activities in the context of realization of a company’s marketing channels formation strategies are explored.
