Characterization and generation of a general class of resource-constrained project scheduling problems : easy and hard instances

Kolisch, Rainer; Sprecher, Arno; Drexl, Andreas - 1992

The paper describes an algorithm for the generation of a general class of precedence- and resource-constrained scheduling problems. Easy and hard instances for the single- and multi-mode resource-constrained project scheduling problem are benchmarked by using the state of the art...

Semi-active, active, and non-delay schedules for the resource-constrained project scheduling problem

Sprecher, Arno; Kolisch, Rainer; Drexl, Andreas - 1993

We consider the resource-constrained project scheduling problem (RCPSP). The focus of the paper is on a formal definition of semi-active, active, and non-delay schedules. Traditionally these schedules establish basic concepts within the job shop scheduling literature. There they are usually...

An Exact Algorithm for the Resource-Constrained Project Scheduling Problem Based on a New Mathematical Formulation

Mingozzi, Aristide; Maniezzo, Vittorio; Ricciardelli, … - In: Management Science 44 (1998) 5, pp. 714-729

In this paper we consider the Project Scheduling Problem with resource constraints, where the objective is to minimize the project makespan. We present a new 0-1 linear programming formulation of the problem that requires an exponential number of variables, corresponding to all feasible subsets...

A solution algorithm for non-convex mixed integer optimization problems with only few continuous variables

Schöbel, Anita; Scholz, Daniel - In: European Journal of Operational Research 232 (2014) 2, pp. 266-275

Geometric branch-and-bound techniques are well-known solution algorithms for non-convex continuous global optimization problems with box constraints. Several approaches can be found in the literature differing mainly in the bounds used.

PRICE PREMIUMS FROM A CERTIFIED FEEDER CALF PRECONDITIONING PROGRAM

Ward, Clement E.; Lalman, David L. - 2003

Preconditioning calf programs, while not new, are becoming more prevalent. They provide benefits to cow-calf producers … preconditioned calves exceeds the marginal costs for preconditioning. This paper reports estimates from two models to determine the … several characteristics that are affected by preconditioning. Data were from seven feeder calf sales in Oklahoma in 2001 and …
