Network problems are manifold and extremely complex. Many problems result from engineering details or mathematical difficulties, others are caused by disregarding economic principles and imperfections of markets. The text provides a fairly integrated approach of transportation related "network problems" and their "solutions" with emphasis on economics or, more precisely, microeconomic theory.

The analysis of this volume represents an attempt to apply modern mathematical techniques to the problems arising from large and significant indivisibilities. While the classical microeconomic theory refers to assumptions about the convexity of production sets and consumer preferences, this book directs the attention to indivisible commodities. It investigates the influence of the assumed indivisibilities of factors and goods on the results of the microeconomic theory of the firm, the theory of the household and market theory.
