When thinking about a hospital queue, we notice a primordial characteristic: it does not follow a chronological order. It is defined by decision of the responsible physician. This decision-making is based on a subjective assessment of the clinical risk of each patient, based on the experience and knowledge of each physician. Thus, the tendency is […]

The hospital logistics area is responsible for all planning, procurement and distribution of supplies within the hospital. A less studied, but extremely important, logistic-hospital problem is the transport […]

Abstract: This paper explores how the consideration of two important practical aspects related to transportation in the forestry industry, wood moisture content and seasonal limitations on the maximal truck’s payload, may lead to savings in procurement costs. To this end, it proposes a multi-period mathematical formulation that decides on the location of potential stockyards and […]
