Reducing bias in a personnel assignment process via multiplicative utility solution

Article Abstract:

A comparison of two methods for solving the matching assignment problem is made to determine the extent of bias resulting from the two differing mathematical algorithms. These two methods are the multiplicative utility solution and the male-optimal stable solution. The equality of treatment of both applicant and employer groups, as influenced by the size of the problem, was measured for both methodologies using simulation modeling. The multiplicative utility approach gave a fairer treatment of the two groups. The extent of bias that resulted from the application of the stable approach varied with changing problem sizes. Bias is quantified as performance differences that are measured statistically.

A nonlinear heuristic short-term model for hydroelectric energy production: the case of the Hazbani-Dan Water System

Article Abstract:

A water resource control problem involving the operational management of a power plant in the Hazbani-Dan Water System is solved using a two-phase decision model. The first phase of the model involves the formulation of a long-tern control model while the second phase involves the development of a short-term control model. The two-phase decision model effectively maximizes the return on energy generated given the presence of several constraining variables such as discharge limitations and storage capacity.

A nonlinear optimization model of water allocation for hydroelectric energy production and irrigation

Article Abstract:

A decision and control model for allocating water from a reservoir is developed. The model was created for the Hazbani-Dan water system in Israel, in which water from the Dan River is allocated for either hydroelectric power or irrigation. The expected return on energy production is maximized by the model. The water demand for irrigation is used as a constraint in the model. The electricity is sold under a three-tiered pricing system to the national electric utility.
