This work is based on a differential game proposed by Kelvin Lancaster. The game between two agents called workers and capitalists is based on the accumulation and redistribution of benefits among social classes concluding that cooperative outcomes outperform non-cooperative. This approach...

A corporation that wants to fully embrace sustainability must address all three pillars of the triple bottom line. Among profit, planet, and people, it is this last category that is hardest to measure directly. When a company has remote locations and cannot directly observe effort, the...

In this paper, we developed and analyzed a dynamic model of the vehicle routing problem. In the stated model, a vehicle with adequate volume travels at a constant velocity in a bounded plane to provide services to independent and uniformly distributed demands. The dynamic demands arrive...

This study aims at investigating and measuring the relative efficiency of public hospitals performance in Jordan, during the period (2006-2008), using DEA and Pabon-Lasso Diagram. The results indicate that the average efficiency of those hospitals is varied and ranges between (73%) to (100%)....

The electric power industry finds itself at a critical juncture—increased regulation of its emissions combined with a shift in U.S. energy policy to emphasize renewable energy. Industry executives must determine the timing and the extent of their investments in clean technology to...

In this paper, we analyze a purchase lot-sizing decision that includes transport cost using actual motor carrier freight rates. Lot-sizing models in the literature either estimate motor carrier freight rates with a continuous function or simplify less-than-truckload freight rates unrealistically...

We consider a general adverse selection model as an optimal control problem with mixed constraints. We prove that under broad conditions the optimal contract exists and is continuous.

What is the optimal way to seed a knock-out tournament in order to maximize the overall spectator interest in it? Seeding affects the set of matches being played in the tournament, while neutral spectators tend to prefer to watch (i) close and intense matches; (ii) matches that involve strong...

This paper proposes a new way to measure and deal with risk within the portfolio selection problem using a skewness/semivariance biobjective optimization framework. The solutions of this biobjective optimization problem allow the investor to analyse the efficient trade-off between skewness and...

Hub and spoke (H&S) network reflecting the scale economies through consolidation and a large amount of freight transportation is widely used to reduce total transportation costs. H&S network has transportation routes that go to the final destination point pass through hub linking destination...
