Background: This paper proposes a novel hybrid group decision making methodology to solve a coalition-formation problem for cooperative replenishment with multiple firms to achieve operational efficiency. We consider a case of horizontal cooperation between firms, and we investigate the profitability of horizontal cooperation when designing collaborative contracts. Methods: This study presents the application of a hybrid approach for group decision support for the coalition -formation problem. Multi-criteria decision making (MCDM) and intuitionistic fuzzy set (IFS) theory have been integrated to provide group decision support under consensus achievement. In addition, this study employs the entropy method to identify the weights of the decision makers. Results: The proposed integrated approach has been further studied through an illustrative example. The decision procedure used here is simply structured so that it may easily be implemented with a computer. Conclusions: This research may be beneficial to decision makers, researchers and organizations in helping them to understand project based evaluation in order to design and plan better horizontal cooperation.

Wstęp: W artykule zaproponowano nową metodologię podejmowania decyzji dotyczących tworzenia koalicji między wieloma firmami w celu osiągnięcia wydajności operacyjnej. Rozważany jest przypadek horyzontalnej współpracy między firmami, a następnie badana jest opłacalność współpracy horyzontalnej przy projektowaniu umów o współpracę. Metody: W pracy przedstawiono zastosowanie podejścia hybrydowego do wspomagania decyzji grupowych w przypadku problemu koalicji. Zintegrowano wielokryterialne podejmowanie decyzji (MCDM) i intuicyjną teorię zbiorów rozmytych (IFS), aby zapewnić grupowe wsparcie decyzji przy osiągnięciu konsensusu. Ponadto zastosowano metodę entropii do identyfikacji wag osób podejmujących decyzje. Wyniki: Proponowane zintegrowane podejście zostało poddane dalszej analizie za pomocą przykładu. Zastosowana tutaj procedura decyzyjna ma prostą strukturę, dzięki czemu można ją łatwo wdrożyć za pomocą komputera. Wnioski: Badania te mogą być korzystne dla decydentów, badaczy i organizacji, pomagając im zaprojektować i zaplanować współpracę horyzontalną.

Aim/purpose – The paper analyses how game theory can be exploited to provide the implementation of profit allocations among the members of the fourth party logistics supply chain coalition system. Design/methodology/approach – The study compares four allocation rules from cooperative game theory in order to explore fair and reasonable sharing of revenue among the partners in the venture. Findings – As a result, more practical situations can be modelled and more supply chain efficiency can be obtained throughout the several steps carried out by decision makers. Our computational analysis establishes that the proposed methods are computationally efficient and can be implemented to solve real-life problems. Research implications/limitations – Our business process simulation of the 4PL supply chain coalition including a simulation of the profit allocation concept allowed us to develop a broad understanding of the management process of the 4PL supply chain coalition approach. Originality/value/contribution – A comparison of the different methods based on game theory provided an opportunity for reaching the prefect collaboration. These views enrich our understanding of the 4PL supply chain coalition and help us to implement an innovative development for the sector.
