Multicriteria optimisation in logistics forwarder activities
Tanja Poletan, Alen Jugović, Ratko Zelenika, 2007, original scientific article

Abstract: Logistics forwarder, as organizer and planner of coordination and integration of all the transport and logistics chains elements, uses adequate ways and methods in the process of planning and decision-making. One of these methods analysed in this paper, which could be used in optimisation of transport and logistics processes and activities of logistics forwarder, is the multicriteria optimisation method. Using that method, in this paper is suggested model of multicriteria optimisation of logistics forwarder activities. The suggested model of optimisation is justified in keeping with method principles of multicriteria optimization, which is included in operation research methods and it represents the process of multicriteria optimization of variants. Among many different processes of multicriteria optimization, PROMETHEE (Preference Ranking OrganizationMethod for Enrichment Evaluations) and Promcalc& Gaia V. 3.2., computer program of multicriteria programming, which is based on the mentioned process, were used.

Inventory cost consequences of variability demand process within a multi-echelon supply chain
Francisco Campuzano Bolarín, Andrej Lisec, Francisco Cruz Lario Esteban, 2008, original scientific article

Abstract: The bullwhip effect (Lee et al, 1997a) is a known supply chain phenomenon where small variations in end item demand create oscillations that amplify throughout the chain. Different price elasticity of demand influence different changes of demand when prices of items are changing on the time horizon. The variance of the orders at the end user placed on suppliers or on manufacturer increases with the orders flow upstream in the logistics chain. This creates harmful consequences in inventory levels and all kind of inventory costs that may affect added value of activities along the logistics chain and finally affect Net Present Value of all activities in the chain. Traditional model of dynamic supply chain structures is used for this particular study, based on the seminal work of Forrester Diagrams (Forrester 1961). Simulation platform for supply chain management at stochastic demand developed by Campuzano (2006) has been used. VENSIM Simulation Software was previously used for developing these supply chain dynamic models. In the development platform generalised supply chain models are constructed graphically and also analytically. Our study here is to get a dipper insight into the processes in a logistics chain, measuring the inventory cost consequences due to variability demand amplification.
