We consider a dynamic inventory (production) model with general convex order (production) costs and excess demand that can be accepted or refused by the firm. Excess demand that is accepted is backlogged and results in a backlog cost whereas demand that is refused results in a lost sales charge....

This paper demonstrates that a class of two-person games with ratio payoff functions can be solved using equivalent primal-dual linear programming formulations. The game's solution contains specialized information which may be used to conduct the efficiency evaluation currently done by the CCR...

A new linear programming formulation for handling categorical outputs in DEA is presented which eliminates the difficulties of interpretation and computation that accompanied earlier mixed integer models.

Science and technology advances drive firms to continually enhance their product's performance and launch sequentially improving offerings. Firms face challenges in marketing such improving products to well-informed, forward-looking consumers who anticipate product improvements and seek to delay...
