a r t i c l e i n f o Keywords: Multi-mode scheduling Ant colony optimization Renewable and nonrenewable resource constraints Construction projects An ant colony optimization (ACO)-based methodology for solving the multi-mode resource-constrained project scheduling problem (MRCPSP) considering both renewable and nonrenewable resources is presented. With regard to the MRCPSP solution consisting ...

This paper studies monopoly extraction of a nonrenewable resource with the presence of a competitively supplied capacity constrained renewable substitute. The monopolist staves off the renewable supply when the latter becomes competitive and then lets the resource price jump up. © 2013 Elsevier B.V. All rights reserved.

A summary is provided of the early history of research on the flow of nonrenewable energy resources through the economy and of the flow of renewable energy resources through a natural ecosystem. The techniques are similar, and many specific applications are provided. A combined economic and ecological technique is also defined. The early history and people of the International Society Ecologica...

A dynamic farm production model analyzes the interaction between the externalities caused by pest mobility and the development of pesticide resistance, a nonrenewable resource, in the context of agricultural biotechnologies. The model measures the effect of farmers’ myopic behavior and the impact of pest mobility on the path of resistance.

This paper deals with the Extended Resource Constrained Project Scheduling Problem (ERCPSP) which is defined by events, nonrenewable resources and precedence constraints between pairs of events. The availability a resource depleted replenished at occurrence times set decision problem ERCPSP consists determining whether an instance has feasible schedule or not. When there only one resource, this...
