This paper contains a nonlinear, nonstationary autoregressive model whose intercept changes deterministically over time. The intercept is a flexible function of time, and its construction bears some resemblance to neural network models. A modelling technique, modified from one for single...

A class of production planning problems is considered in which known demands have to be satisfied over a finite horizon at minimum total costs. For each period, production and storage cost functions are specified. The production costs may include set-up costs and the production levels may he...

The intersecting global societal and natural-environmental systems are described in terms of evolution, instability and structural change. Systems theory, particularly a number of constructs from dissipative-structure theory and synergetics, are applied in this description. The policy meaning of...
