Classical inventory theory often assumes no discrepancies between recorded inventory and actual inventory. However, inventory records are usually inaccurate due to many reasons in practice. For example, inventory shrinkage refers to the difference between booked inventory that a company should...

This paper considers a multi-product newsboy system that produces multiple products for fulfilling independently uncertain demands, which share the same production capacity. To deal with possible shortage of limited capacity, productions can be outsourced. We consider two outsourcing strategies:...

This paper considers a multi-product newsvendor problem with multiple constraints. Multiple constraints in the problem make it more challenging to solve. Previous research has attempted to solve the problem by considering two-constraint case or/and using approximation techniques or active sets...

In this paper, a unified algorithm is proposed for solving a class of convex separable nonlinear knapsack problems, which are characterized by positive marginal cost (PMC) and increasing marginal loss-cost ratio (IMLCR). By taking advantage of these two characteristics, the proposed algorithm is...
