This paper recognizes that individuals working in the nonprofit sector can have different motives and investigates which type of manager nonprofit organizations should best employ. It first considers a situation in which the manager is allowed to attract only one employee and later extends the...

We consider the finite-horizon discrete-time economic order quantity problem. Kovalev and Ng (2008) have developed a solution approach for solving this problem. Their approach requires a search for the optimal number of orders, which takes O(logn) time. In this note, we present a modified...

This paper presents the results of the application of the modified Hopfield network to the travelling salesman problem (TSP). A cost function of the TSP consists of four components: two terms which ensure that the salesman's tour is valid, the term which forces neurons to have the output signal...

We develop a branch-and-price algorithm for constructing an optimal product line using partworth estimates from choice-based conjoint analysis. The algorithm determines the specific attribute levels for each multiattribute product in a set of products to maximize the resulting product line's...

Iterated Local Search has many of the desirable features of a metaheuristic: it is simple, easy to implement, robust, and highly effective. The essential idea of Iterated Local Search lies in focusing the search not on the full space of solutions but on a smaller subspace defined by the...
