In this paper, we propose an exact solution method for single machine scheduling problems typically arising from bottleneck-based decomposition of weighted tardiness job shops. The encountered subproblems are characterized by delayed precedence constraints, multiple local due dates per operation...

The planning problems confronting logistics service providers frequently involve complex decisions. Motivated by a real-life case study, this paper considers short-range weekly planning on the part of postal companies that must decide about pickup tours and delivery tours for fluctuating volume...

In this article we will develop a mathematical model for a cost-efficient selection of vehicles with varying capacities for line haul transports with leasing options. For this integer optimization problem, which is a variant of the generalized assignment problem known as NP-hard, we will compare...
