On the $$\varvec{(Q,r)}$$(Q,r) policy for perishables with positive lead times and multiple outstanding orders

Analysis of the (Q, r) Inventory Model for Perishables with Positive Lead Times and Lost Sales

A multiple objective approach for joint ordering and pricing planning problem with stochastic lead times

The integration of marketing and demand with logistics and inventories (supply side of companies) may cause multiple improvements; it can revolutionize the management of the revenue of rental companies, hotels, and airlines. In this paper, we develop a multi-objective pricing-inventory model for a retailer. Maximizing the retailer's profit and the service level are the objectives, and shorta...

An approximate policy for a dual-sourcing inventory model with positive lead times and binomial yield

This paper studies the inventory system of a retailer who orders his products from two supply sources, a local one that is responsive and reliable, but expensive, and a global one that is low-cost but less reliable. The deliveries from the global source only partially satisfy the quality requirements.Wemodel this situationwith a dual-sourcing inventory model with positive lead times and random ...

Periodic Review Inventory Policy for Perishables with Random Lifetime

ABSTRACT: We consider a periodic review inventory system for perishable items with lost sales. Demands arrive according to a Poisson process. The lifetime of each item is exponentially distributed and the procurement lead time is constant. This type of modeling is motivated by the recent application of the so called Time Temperature Technologies. With this technology, it is possible to detect a...

A smoothing replenishment policy with endogenous lead times

We consider a two echelon supply chain: a single retailer holds a finished goods inventory to meet an i.i.d. customer demand, and a single manufacturer produces the retailer’s replenishment orders on a make-to-order basis. In this setting the retailer’s order decision has a direct impact on the manufacturer’s production. It is a well known phenomenon that inventory control policies at the retai...
