We study a pure assemble-to-order system subject to multiple demand classes where customer orders arrive according to a …

The central issue in supply chain management is to match supply with demand, and the heart of a planning model is the … modeling of supply and demand functions. To allow for analytical tractability, the existing literature often assumes almost … surely linear supply and demand functions, which greatly limits the applicability of the models. The goal of this paper is to …

We consider a single-product discrete-time inventory model with intermittent demand. In every period, either zero … demand or a positive demand is observed with an unknown probability. The distribution of the positive demand is assumed to be … available but it is a function of the unknown intermittent demand parameters that must be estimated from a limited amount of …

We consider a periodic-review perishable inventory system with multiple demand classes, each characterized by a …

demand distribution are not known a priori. Unsatisfied demand is lost and unobserved, and the only available information for … decision-making is the observed sales data (a.k.a. censored demand). Conventional approaches, such as stochastic approximation … the demand-price function is constructed, and then the corresponding surrogate optimization problem is solved on a sparse …

We consider an inventory control problem with lost-sales in a shifting demand environment. Over a planning horizon of T … periods, demand distributions can change up to O(log T) times, but the firm does not know the demand distributions before or … changes and learn the demand distributions only from historical sales data. We show that with censored demand, active …

a Bayesian updating framework to learn both the demand distribution parameter and the substitution probability … unobservability of lost sales requires "stock more". Two, the tangling of substitution demand and primary demand in the regular sales … phase. To better observe the primary demand requires "stock more" for the discounted product, which reduces the substitution …
