Buyer vendor coordination models in supply chain management,

Abstract Coordination between two different business entities is an important way to gain competitive advantage as it lowers supply chain cost. This paper reviews literature dealing with buyer vendor coordination models that have used quantity discount as coordination mechanism under deterministic environment and classified the various models. An effort has also been made to identify critical issues and scope of future research

Optimization models of the supply of power structures’ organizational units with centralized procurement

Management of the state power structures’ organizational units for materiel and technical support requires the use of effective tools for supporting decisions, due to the complexity, interdependence, and dynamism of supply in the market economy. The corporate nature of power structures is of particular interest to centralized procurement management, as it provides significant advantages through coordination, eliminating duplication, and economy of scale. This article presents optimization models of the supply of state power structures’ organizational units with centralized procurement, for different levels of simulated materiel and technical support processes. The models allow us to find the most profitable options for state power structures’ organizational supply units in a centre-oriented logistics system in conditions of the changing needs, volume of allocated funds, and logistics costs that accompany the process of supply, by maximizing the provision level of organizational units with necessary material and technical resources for the entire planning period of supply by minimizing the total logistical costs, taking into account the diverse nature and the different priorities of organizational units and material and technical resources

Enhancing Enterprise Resilience through Enterprise Collaboration

Current environments, characterised by turbulent changes and unforeseen events, consider resilience as a decisive aspect for enterprises to create advantages over less adaptive competitors. Furthermore, the consideration of establishing collaborative processes among partners of the same network is a key issue to help enterprises to deal with changeable environments. In this paper both concepts, resilience and collaborative processes establishment, are associated in order to help organisations to handle disruptive events. The research objective is to identify collaborative processes whose positive influences assist enterprises against disruptions, reducing the effects of disturbances in dynamic environments.Andres, B.; Poler R. (2013). Enhancing Enterprise Resilience through Enterprise Collaboration. IFAC papers online. 7(1):688-693. doi:10.3182/20130619-3-RU-3018.00283S6886937

Supply chain collaboration

In the past, research in operations management focused on single-firm analysis. Its goal was to provide managers in practice with suitable tools to improve the performance of their firm by calculating optimal inventory quantities, among others. Nowadays, business decisions are dominated by the globalization of markets and increased competition among firms. Further, more and more products reach the customer through supply chains that are composed of independent firms. Following these trends, research in operations management has shifted its focus from single-firm analysis to multi-firm analysis, in particular to improving the efficiency and performance of supply chains under decentralized control. The main characteristics of such chains are that the firms in the chain are independent actors who try to optimize their individual objectives, and that the decisions taken by a firm do also affect the performance of the other parties in the supply chain. These interactions among firms’ decisions ask for alignment and coordination of actions. Therefore, game theory, the study of situations of cooperation or conflict among heterogenous actors, is very well suited to deal with these interactions. This has been recognized by researchers in the field, since there are an ever increasing number of papers that applies tools, methods and models from game theory to supply chain problems

Leader-follower Game in VMI System with Limited Production Capacity Considering Wholesale and Retail Prices

VMI (Vendor Managed Inventory) is a widely used cooperative inventory policy in supply chains in which each enterprise has its autonomy in pricing. This paper discusses a leader-follower Stackelberg game in a VMI supply chain where the manufacturer, as a leader, produces a single product with a limited production capacity and delivers it at a wholesale price to multiple different retailers, as the followers, who then sell the product in dispersed and independent markets at retail prices. An algorithm is then developed to determine the equilibrium of the Stackelberg game. Finally, a numerical study is conducted to understand the influence of the Stackelberg equilibrium and market related parameters on the profits of the manufacturer and its retailers. Through the numerical example, our research demonstrates that: (a) the market related parameters have significant influence on the manufacturer’ and its retailers’ profits; (b) a retailer’s profit may not be necessarily lowered when it is charged with a higher inventory cost by the manufacturer; (c) the equilibrium of the Stackelberg equilibrium benefits the manufacturer.Stackelberg Game;Supply Chain;Vendor Managed Inventory

Primjena ERP sustava za poboljšanje koordinacije internog dobavljačkog lanca

In today\u27s competitive global market, one of the most effective ways towards achieving competitive advantage has been the ability to accelerate the supply chain process through ERP (Enterprise Resource Planning) systems. ERP enables a more efficient internal and external supply chain. Enterprise resource planning system is an information system that manages all aspects of a business (production planning, sales, distribution, accounting, purchasing and customer services). Planning system is the core of an ERP system. The aim of this paper is to propose a hierarchical planning and scheduling model based on just-in-time principle to improve internal supply chain coordination for one-piece and small batch production. The model is implemented into the system ERPINS (Enterprise Resource Planning ININ Solutions) that is developed for metal processing industry, wood and food processing industry and construction industry.Na današnjem konkurentnom globalnom tržištu jedan od najučinkovitijih načina postizanja konkurentne prednosti je sposobnost ubrzanja procesa dobavljačkog lanca pomoću ERP (Enterprise Resource Planning) sustava koji omogućava učinkovitiji interni i eksterni dobavljački lanac. Enterprise resource planning sustav je informacijski sustav koji upravlja svim aspektima poslovanja (planiranje proizvodnje, prodaja, distribucija, računovodstvo, nabava i korisničke usluge). Sustav planiranja je glavni dio ERP sustava. Cilj ovog rada je dati model višerazinskog planiranja i terminiranja koji je zasnovan na just-in-time principu sa svrhom poboljšane koordinacije internog dobavljačkog lanca za pojedinačnu i maloserijsku proizvodnju. Model je primijenjen u sustavu ERPINS (Enterprise Resource Planning ININ Solutions) razvijenom za metaloprerađivačku, drvnu, prehrambenu i građevinsku industriju
