In this paper we introduce a new class of OR games: economic lot-sizing (ELS) games. There are a number of retailers that have a known demand for a fixed number of periods. To satisfy demand the retailers order products at the same manufacturer. By placing joint orders instead of individual orders, costs can be reduced and a cooperative game arises. In this paper we show that ELS games are bala...

We analyze the benefit of production/service capacity sharing for a set of independent firms. Firms have the choice of either operating their own production/service facilities or investing in a facility that is shared. Facilities are modeled as queueing systems with finite service rates. Firms decide on capacity levels (the service rate) to minimize delay costs and capacity investment costs pos...

We investigate the incentives behind investments by competing companies in discovery of their security vulnerabilities and sharing of their findings. Specifically, we consider a game between competing firms that utilise a common platform in their systems. The game consists of two stages: firms must decide how much to invest in researching vulnerabilities, and thereafter, how much of their findi...

A (or a group of) selling agent wants to allocate and sell a (or a set of) parcel of land optimally and fairly to a buying agent within the capacity constraint of the selling agent and budget constraint of the buying agent. This problem has been solved by combining the concept of algorithmic cooperative game theory and financial cryptography. This is an approach for a group of decision-making a...

This paper develops a game theoretic model of a one-manufacturer and one-retailer supply chain allowing the second ordering to investigate how to coordinate the order quantity and advertising investment via a markdown money-cooperative advertising contract. We focus on the effects of allowing the second ordering on equilibrium outcome and coordination mechanism. We find: the relationship betwee...

Multi-robot systems involve the distribution of robotic resources and information. Being an opportunity, they require cooperation among robots so that potential advantages of distribution become effective. Cooperation requires in turn efficiently sharing information and proper coordination. This article extends previous work, regarding efficient information sharing in the context of volumetric ...

Although recent decades have witnessed rapid development of e-commerce, direct sale time-sensitive commodities on e-commerce platforms still faces significant challenges due to the dilemma between short delivery time and high costs. To alleviate these challenges, manufacturers with online retailing operations attempted cooperate offline retailers by using an “order-online, pickup-offline” (OOPO...

We analyze the problem of allocating cost savings from sharing demand information in a three-level supply chain with a manufacturer, a distributor and a retailer. To …nd a unique allocation scheme we use concepts from cooperative game theory. First, we compute analytically the expected cost incurred by the manufacturer and then use simulation to obtain expected costs for the distributor and the...
