In a recent paper, Soni and Shah [Soni, H., Shah, N. H., 2008. Optimal ordering policy for stock-dependent demand under progressive payment scheme. European Journal of Operational Research 184, 91-100] developed a model to find the optimal ordering policy for a retailer with stock-dependent demand and a supplier that offers a progressive payment scheme to the retailer. This note corrects some e...

An undesired observation known as the bullwhip effect in supply chain management leads to excessive oscillations of the inventory and order levels. This paper presents how to quantify and mitigate the bullwhip effect by introducing model predictive control (MPC) strategy into the ordering policy for a benchmark supply chain system. Instead of quantifying the bullwhip effect with commonly used s...

Monetary policy rule might be helpful to avoid the problem of time inconsistency provided there is a commitment to the rule. The commitment is the ability of a government to bind future policies. However, it doesn’t include intrinsic motivations. Therefore, hegemony, which includes both intrinsic and extrinsic motivations, better solves the problem of  time inconsistency. In this paper, we expl...

This research develops two models to consider retailer sales promotion and manufacturer trade under demand uncertainty. The objective of the first model is determine retailer’s optimal promotional effort order quantity while maximizing profit exogenous promotion. second extends manufacturer’s endogenous decisions. For these models, three different policies (off-invoice, scan-back, unsold-discou...

the planning of production and control of inventory problem is one of most important problems that companies are face with them. some times inattention to uncertainty in these problems causes to increase of costs of inventory control systems. one of the important ways encountering to uncertainty is the widespread of fuzzy sets instead of crisp numbers because in this approach, we can determine ...
