The basic deterministic stationary inventory problem, in which backorders are allowed, is analyzed. Instead of considering the backorder cost to be a cost per unit and per time, we also suppose the presence of a fixed backorder cost per unit. The latter generates a supplementary dependence of...

We present an effective scheduling heuristic for realistic production planning in a petrochemical blending plant? The considered model takes into account orders spanning a multi-product portfolio with multiple bills of materials per product, that need to be scheduled on shared production...

We consider a selective vehicle routing problem, in which customers belonging to di?fferent partners in a logistic coalition are served in a single logistic operation with multiple vehicles. Each partner determines a cost of non-delivery (CND) for each of its customers, and a central algorithm...
