Kirytopoulos, K., Leopoulos, V., Mavrotas, G. and Voulgaridou, D. 2010, ‘Multiple Sourcing Strategies and Order Allocation: an ANP-AUGMECON meta-model’, Supply Chain Management: an International Journal, Emerald, 15(4), 263-276.


Purpose – The strategic importance of sourcing is inherent in the positioning of the purchasing operation in a supply chain and supplier evaluation – a crucial step in sourcing – is a complex multicriteria decision making (MCDM) problem. The purpose of this paper is to provide a meta-model for supplier evaluation and order quantity allocation, based on a MCDM method, namely the Analytic Network Process (ANP) and a multiobjective mathematical programming method (MOMP), the AUGMECON.

Design/methodology/approach – The proposed approach consists of two parts. The former develops and applies the ANP method in order to evaluate the suppliers in qualitative terms. The latter implements the AUGMECON method in order to find the Pareto optimal solutions for the allocation of order quantities in a multiple sourcing environment. The integrated meta-model is exposed through an illustrative case concerning the parapharmaceutical enterprise cluster in Greece.

Findings – The proposed meta-model constitutes an efficient method that enables managers to actively participate in the decision making process and exploit the "qualitative value" of their suppliers, while minimizing the costs and the mean delivery times. In addition, it is proved to be suitable for the enterprise clusters, as it adapts a multiple sourcing strategy and enhances the partnership among the members.

Research limitations/implications – The outcome of the model is highly dependent on the inputs provided by the decision maker. Moreover, the ANP method is computational intensive, but this limitation can be alleviated by appropriate software tools.

Originality/value – The proposed meta-model is an innovative approach for decision making in the area of multiple sourcing and order allocation.
