In real world scheduling systems, task or job attributes are stochastic and sequence dependent, learning improves attributes, and schedulers use their cost (or disutility) functions to evaluate schedules with respect to multiple criteria. This paper addresses a stochastic bicriteria single...

An important routing problem is to determine an optimal path through a multi-attribute network which minimizes a cost function of path attributes. In this paper, we study an optimal path problem in a bi-attribute network where the cost function for path evaluation is fractional. The problem can...

The two dimensions of competitiveness are efficiency and effectiveness. Efficiency, in terms of production of goods and services at the least possible costs and effectiveness in terms of achieving the company goals and objectives in terms of quality, customer service, market share, community...
