The purpose of this problem is to choose a set of project activities for crashing, in a way that the expected project time, cost and risk are minimized and the expected quality is maximized. In this problem, each project activity can be performed with a specific executive mode. Each executive mode is characterized with four measures, namely the expected time, cost, quality and risk. In this pap...

This article makes an attempt to build on the extant literature time–cost trade-off in a transportation problem. The idea is agglomerate world of multiple shipment options along with uncertainty demand/supply requirements traditional set-up. introduces bi-objective model multi-choice cost and time coefficients interval demand supply constraints. Such framework more generalized provides much bro...

In most of the cost-utility literature, quality-adjusted life-year (QALY) gains are interpreted as a measure of social value. Given this interpretation, the validity of different multi-attribute health-state scaling instruments may be tested by comparing the values they provide on the 0-1 QALY scale with directly elicited preferences for person trade-offs between different treatments (equivalen...

OBJECTIVE Evaluation of the incremental cost-effectiveness of therapy for amblyopia. DESIGN Cost-utility reference-case analysis. METHODS A cost-utility analysis was performed from a third-party insurer perspective by using decision analysis, evidence-based data from the literature, and patient preference-based time trade-off utility values. DATABASE Patient-derived time trade-off ocular ...

Is the Quantity-Quality Trade-off a Trade-off for All, None, or Some? Although the theoretical trade-off between the quantity and quality of children is wellestablished, empirical evidence supporting such a causal relationship − particularly on child health − is limited. We use two measures of child health to asses the quantity-quality tradeoff across the entire distribution. Using data from th...
