Numerous physiological reactions of cells in dependence on ligand receptor interactions, e.g. variation of growth and division, locomotion and intracellular movement, cell shape and others, depend directly or indirectly on the functional state of the

Among the most commonly occurring mixed-integer problems in operations research are linear programs with fixed charge objective functions. In this paper special structures of the equivalent form of such problems obtained from optimal solutions to the

The application of linear and non-linear programming duality theory to capital budgeting models had resulted in the identification of various properties of optimal solutions and has provided economic interpretations of the models. This paper illustra

The capital budgeting problem is treated as a part of the general theory of choice, where utility is to be maximized subject to the opportunities and constraints. The utility function is assumed to be quadratic to take care of any risk-averse behavio

One commonly employed branch-and-bound approach to 0-1 mixed-integer programming problems is to use bounds obtained from the Benders' partitioning of the problem as a device to restrict the enumeration. We investigate the strength of such bounds thro

A regional wastewater quality management system was modeled as a fixed-charge network flow problem. The model included alternative trunk-line connections, methods of treatment, and variation in system boundaries. The paper describes the model, develo

This paper describes the application of optimization techniques to the problems of garage location and bus routing. The technique employed involves the decomposition of a garage location and bus routing model into two submodels. Solutions for the gar

Many well-known transportation, communication, and facilities location problems in operations research can be formulated as fixed charge network problems, i.e. as minimum cost flow problems on a capacitated network in one commodity where some arcs ha

The capital budgeting problem for a firm deals with the allocation of limited amounts of capital among a specified set of investment opportunities. In this article, we assume the investment opportunities are indivisible in nature and that the firm de

The lock box problem involves the location of post office boxes within a company's distribution area. Customer remittances are mailed to these boxes and the checks are processed by a local bank. The problem is to locate the boxes in a way that will m
