We optimize a large country's currency supply network for its central bank. The central bank provides currency to all branches (who in turn serve consumers and commerce) through its network of big vaults, regional vaults, and retail vaults. The central bank intends to reduce its total...

The differentiation of products and services parallel with the globalization, motivated researchers to commit resources within supply chains more effectively. Competitive nature of the markets requires innovativeness with swift actions to supply mass customized demand. The total cost in the...

By using the methods of multi-criteria analysis it is possible to make decisions which have significant influence on companies' business. The aim of this paper is to evaluate different suppliers using the integrated model that recognizes a combination of fuzzy AHP (Analytical Hierarchy Process)...

A data processing procedure, DEA (Data Envelopment Analysis) is described as as an analytical tool in audit engagement. DEA receives data inputs from from financial statements of a plurality of clients, constructs efficiency frontiers and evaluates relative income efficiencies. DEA can be used...

We explore the implications for asset prices and implied volatilities in an equilibrium model of commodity production. Production of the commodity can be carried out in one of two regimes. In the first regime the reserves are set in constant decline while in the second regime new additions to...

This paper studies the implications for reserve lifetime and related quantities in a continuous time model of resource extraction under uncertainty. Both the resource price and the extracted amount are assumed to follow stochastic processes. Reserve lifetime is determined by the...

Theories of regulation have generally been tested by using a regression approach or an an event study approach. This paper was inspired by the Coase (1937) theory of the firm. It used Data Envelopment Analysis (DEA) to test the economic consequences of the Occupational Health and Safety...

We consider a novel generalization of the resource-constrained project scheduling problem (RCPSP). Unlike many established approaches for the RCPSP that aim to minimize the makespan of the project for given static capacity constraints, we consider the important real-life aspect that capacity...

This paper is concerned with solving a vendor–buyer integrated inventory problem with rework and a specific multi-delivery policy by a two-phase algebraic approach. Conventional method to the problem is to use differential calculus and Hessian matrix equations to prove convexity of system cost...

We study a retailer's sourcing contract when the supplier's reservation profit (offered by his outside options) depends on his cost, which is privately known to only the supplier. An interesting discovery from our analysis is that supply chain coordination may be achieved despite the...
