This paper provides a theory of endogenous network formation in over-the-counter markets based on trade competition and inventory risk balancing. A core-periphery network structure arises as an equilibrium outcome. A small number of agents emerge as core dealers to intermediate among a large number of peripheral agents. The equilibrium level of dealer entry (the size of the core) depends on the...

Public Bicycle Sharing System (PBSS) is used as a way to reduce traffic and pollution in cities. Its performance is related to availability of bicycles for picking up and free docks to return them. Existence of different demand types leads to the emergence of imbalanced stations. Here, we try to balance inventory of stations via defining maximal response rates for each type of rental request. I...

The main goal of this paper is to develop a new generalization of balancing and Lucas-balancing sequences namely balancing and Lucas-balancing $p$-numbers and derive several identities related to them. Some combinatorial forms of these numbers are also presented.

Using the mathematic techniques such as Fuzzy approach has useful outcomes for production planning in different sources. In this paper LGP1 was used to model the objectives such as: avoidance of shortage or surplus of demand, access to maximum of income, using the normal capacity of production and organizing the inventory of warehouse, within the framework of Goal constraints like balancing b...

To prevent global warming by supply chain, End-of-Life (EOL) assembly products should be disassembled environmentally and economically for material circulation (Wang and Gupta, 2011). This paper proposes a disassembly system design with an optimal environmental and economic parts selection which harmonizes collected CO2 volumes and recycling cost using a Life Cycle (LC) inventory database by th...

This paper studies the problem of optimal flow control in dynamic inventory systems. A dynamic optimal distribution problem, including time-varying supply and demand, capacity constraints on the transportation lines, and convex flow cost functions of Legendre-type, is formalized and solved. The time-varying optimal flow is characterized in terms of the time-varying dual variables of a correspon...

In this paper, we establish that maintaining a balanced workload on each machine over time stochastically minimizes the work-in-process inventory in certain types of flexible manufacturing systems (FM%) with finite or infinite common input buffer storage and an ample buffer et each machine. The results obtained here complement those obtained by Stecke and Morin (1985), in which it is establishe...

Horizontal collaboration is a promising avenue to improve the efficiency of logistical operations. However, benefits strongly depend on degree fit between partners. In this paper, we analyze impact partners' product characteristics those benefits, focusing their innovativeness. Companies supplying functional versus innovative products have different requirements in supply chain and responsivene...

Numerous works has been done for load balancing of web servers in grid environment. Reason behinds popularity of grid environment is to allow accessing distributed resources which are located at remote locations. For effective utilization, load must be balanced among all resources. Importance of load balancing is discussed by distinguishing the system between without load balancing and with loa...
