This paper studies the coordination issue of a supply chain consisting of one retailer and two suppliers, amain supplier and a backup supplier. The main supplier’s yield is subject to disruption and the retailer faces a random demand. We determine the retailer’s optimal ordering policy and the main supplier’s production quantity that maximize expected profit of the centralized supply chain. We ...

Robust supplier selection problem, in a scenario-based approach has been proposed, when the demand and exchange rates are subject to uncertainties. First, a deterministic multi-objective mixed integer linear programming is developed; then, the robust counterpart of the proposed mixed integer linear programming is presented using the recent extension in robust optimization theory. We discuss dec...

Recently, price contract models between suppliers and retailers, with stochastic demand have been analyzed based on well-known newsvendor problems. In Bernstein and Federgruen [6], they have analyzed a contract model with single supplier and multiples retailers and price dependent demand, where retailers compete on retail prices. Each retailer decides a number of products he procures from the s...

In this paper, we study a make-to-stock manufacturing system where two firms compete through dynamic pricing and inventory control. Our goal is to address competition (in particular a duopoly setting) together with the presence of demand uncertainty. We consider a dynamic setting where multiple products share production capacity. We introduce a demand-based fluid model where the demand is a lin...

Consider a firm that satisfies its demand for a specified time period by assigning it to a supplier via a procurement (reverse) auction; call this the standard auction. The firm is considering first breaking the demand down into smaller time periods and permitting bids for one or more of these sub-periods, either as independent bids or as package bids; call this the unbundled auction. Choosing ...

Abstract: In this paper a study has been carried out using crisp and fuzzy inventory model for the deteriorating items under trapezoidal fuzzy numbers when the supplier offered price discount to the retailer at the time of replenishment. In this model the deterioration rate is constant. Many researchers suggested, demand rate in the inventory models are constant, exponential (increase/decrease)...

This paper presents a hybrid algorithm for supplier evaluation and demand allocation among the suppliers. The objective here is to minimise the inventory and transportation costs and simultaneously to maximise the total purchase value of the items taking into consideration demand condition, supplier capacity, budget and delivery lead-time constraints. Since the problem is multi-objective decisi...

Many retailers often partner with one supplier in each product category, referred to as the “category captain”, and work closely with this supplier on consumer-centric, demand-enhancing initiatives within the store. While the promise of joint growth has spurred many such initiatives, some suppliers and retailers are unclear about the true returns from collaboration. Regulators, at times, are wo...

We consider a supply chain in which a single supplier with fixed capacity sells to several independent retailers or manufacturers. The retailers have private information about their individual markets (e.g., mean market demand), which influences the size of their orders to the supplier. If the sum of all retailer orders exceeds the supplier’s capacity, the supplier uses a pre-declared rule, whi...
