Supply chain integration is postulated as the key to achieve supply chain management excellence. There is an equivocal claim that Japanese companies are better at managing their supply chains. Yet, little is known about the Japanese food supply chain. Ten interviews with supply chain managers were conducted using an open ended interview approach. These companies were randomly selected based on Japan External Trade Organizations (JETRO) listing. Using a qualitative approach, the findings indicate that a short and simple structure is a platform of the food supply chain. Furthermore, the companies extremely interface with suppliers of raw materials (backward integration) and seriously concern about coordinating and integrating cross functional processes within the companies (internal integration). In addition, these companies portray to have a moderate level of integration with their customers (forward integration). Finally, the Japanese management styles appear to be a pivotal supporting element in managing the integrated food supply chain.
Markowitz mean-variance portfolio theory is one of the most widely used approaches in portfolio selection. Recently another possible approach have been developed showing that efficient portfolios can be found by solving stochastic dominance constrained portfolio optimization problem. In this paper, we consider portfolio optimization problem with Second order Stochastic Dominance (SSD) constraints for Borsa Istanbul Stocks. Our results show that, for Borsa Istanbul, more efficient portfolios can be obtained with SSD constraint than conventional one. Furthermore we present SSD pairwise efficiency of stocks returns at Borsa Istanbul by using second order SD criteria. The results are important in terms of risk measures of an investment return.
