This paper studies the simultaneous dock assignment and sequencing of inbound trucks for a multi-door cross docking operation with the objective to minimize total weighted tardiness, under a fixed outbound truck departure schedule. The problem is newly formulated and solved by six different...

Firms need to deal with not only risks from stochastic demand but also risks from supply side. The supply side risk may be due to parts/service outsourcing, third party logistics, or random yield in production processes. In this paper, we study how firms sequentially make price and quantity...

We consider a single item assembled from two components. One of the components has a long lead time, high holding cost and short review period as compared to the other one. We assume that net stocks are reviewed periodically, customer demand is stochastic and unsatisfied demand is backordered....

We consider a single period inventory problem with three non-identical retailers in which items can be pooled at a predetermined point in time. Since multiple items are often pooled with a single visit to each retailer, we use a predetermined (shortest) route for redistribution. We derive cost...

A simulation optimization framework is proposed for supply chain inventory management of highly perishable products. A new replenishment policy based on old inventory ratio is developed, hence called OIR policy. It is an age-based policy using only partial age information to measure the...

In clinical practice, red blood cells (RBCs) have a maximal shelf life (MSL) of 42 days. Recent studies suggest managing RBC inventory with a more restrictive MSL. To this end, a new simulation optimization (SO) framework is proposed for blood supply chain inventory management with ABO blood...

We consider the stochastic economic lot scheduling problem (SELSP) with lost sales and random demand where switching between products is subject to sequence-dependent setup times. We propose a solution based on simulation optimization using an iterative two-step procedure which combines global...

The continuous rise in environmental awareness has affected several aspects of the global economy, including supply chain management. Traditionally, supply chains are designed and operated in a way that minimizes costs and increases profitability; however, this is not sufficient nowadays. It is...

We consider a group scheduling problem in a hybrid flowshop where the parallel machines in one or more stages of the flowshop are unrelated and have different run times for the same job. The objective of the problem is to simultaneously decrease the producer's cost by minimizing the...

Scheduling problem in a cellular manufacturing system is treated as the group scheduling problem, assuming that intercellular moves can be eliminated by duplicating machines. However, in a typical CMS, duplicating bottleneck machines may be costly and infeasible. This fact limits the...
