This paper offers insights into how the bullwhip effect in two parallel supply chains with interacting price-sensitive demands is affected in contrast to the situation of a single product in a serial supply chain. In particular, this research studies two parallel supply chains, each consisting...

The goal of this paper is to quantify the impact of Inventory Record Inaccuracy on the dynamics of collaborative supply chains, both in terms of operational performance (i.e. order and inventory stability), and customer service level. To do so, we model an Information Exchange Supply Chain under...

We provide a novel approach to characterize the order process of continuous review (s,S) and (r,nQ) inventory policies, and study the impact of the batching parameter (the value of Q or S-s) on the variability in the order process. First, we characterize the distribution of the time between...

We consider a decentralized supply chain comprised of one manufacturer and one retailer where the manufacturer has random yield, and the retailer faces uncertain demand. To guarantee product availability, the retailer requires a service level of the product supply from the manufacturer. However,...

This paper studies the optimal investment strategies of an incumbent and a potential entrant that can both choose between a product flexible and dedicated technology, in a two-product market characterized by uncertain demand. The product flexible production technology has certain advantages,...

Demand fluctuations that cause variations in output levels will affect a firm’s technical inefficiency. To assess this demand effect, a demand-truncated production function is developed and an “effectiveness” measure is proposed. Often a firm can adjust some input resources influencing the...

This paper investigates the relationship between market conditions and the value and use of sourcing flexibility for service processes. We develop and analyze a series of models, and we derive expressions for the optimal switching decision, the value of the option to outsource, the value of the...

We establish a flexible capacity strategy model with multiple market periods under demand uncertainty and investment constraints. In the model, a firm makes its capacity decision under a financial budget constraint at the beginning of the planning horizon which embraces n market periods. In each...

In this paper we develop a stochastic programming approach to solve a multi-period multi-product multi-site aggregate production planning problem in a green supply chain for a medium-term planning horizon under the assumption of demand uncertainty. The proposed model has the following features:...

It is very common to assume deterministic demand in the literature of integrated targeting – inventory models. However, if variability in demand is high, there may be significant disruptions from using the deterministic solution in probabilistic environment. Thus, the model would not be...
