Human language, over its evolutionary history, has emerged as one of the fundamental defining characteristic of the modern man. However, this milestone evolutionary process through natural selection has not left any ’linguistic fossils’ that may enable us to trace back the actual course of development of language and its establishment in human societies. Lacking analytical tools to fathom the cr...

The recent development of a Human Rights and Social Responsibility Policy for fishery improvement projects (FIPs) has accelerated industry NGO-led initiatives to address human labour rights violations in seafood supply chains through FIPs. However, this brief communication demonstrates that FIPs’ social requirements, as currently constituted reported, suffer from many the same problems other vo...

In robust optimization, the multi-stage context (or dynamic decision-making) assumes that the information is revealed in stages. So, part of the decisions must be taken before knowing the real values of the uncertain parameters, and another part, called recourse decisions, is taken when the information is known. In this paper, we are interested in a robust version of the location transportation...

This work proposes a hybrid of stochastic programming (SP) approaches for an optimal midterm refinery planning that addresses three sources f uncertainties: prices of crude oil and saleable products, demands, and yields. An SP technique that utilizes compensating slack variables is mployed to explicitly account for constraints’ violations to increase model tractability. Four approaches are cons...

In this paper, we consider a variant of adaptive robust combinatorial optimization problems where the decision maker can prepare K solutions and choose best among them upon knowledge true data realizations. We suppose that uncertainty may affect objective constraints through functions are not necessarily linear. propose new exact algorithm for solving these when feasible set nominal problem doe...
