Optimising the Supplier System of Network-Like Operating Assembly Plants

Abstract

This paper is analysing how the different factors influence the suppliers of each component parts and the optimum number of yearly transports, using a simplified cost function as objective function, based on a general model used for designing and running network-like operating supplier-assembly logistics systems, which has been detailed in former publications. The authors introduce the data structure required for the calculation in the following chapter, then they analyse the influence of each characteristics of the objective function parameters and their relative ratios of one to another in relation to several suppliers and customers, using the method of total discount with limited number of transports as well as using a heuristic algorithm (former analyses referred to one customer i.e. one production company). In the end part, evaluation and comparison of results of the two methods (limited total discount and heuristic algorithm) related to the introduced model and drafting further tasks required for optimum operation of the supplier system will take place, such as taking the capacity limits of the suppliers and combined supplies of several component parts from some suppliers into consideration.
