Scheduling School Buses

Swersey, Arthur J.; Ballard, Wilson - In: Management Science 30 (1984) 7, pp. 844-853

In the scheduling situation considered here, we are given a set of routes, each associated with a particular school. A single bus is assigned to each route, picking up the students and arriving at their school within a specified time window. The scheduling problem is to find the fewest buses...

Integer Programming Solution of a Classification Problem

Liittschwager, J. M.; Wang, C. - In: Management Science 24 (1978) 14, pp. 1515-1525

A classification problem is presented in which it is desired to assign a new individual or observation with k characteristics to one of two distinct populations based upon historical sets of samples from the two populations. The resulting classification problem is formulated as a mixed-integer...

School Timetabling---A Case in Large Binary Integer Linear Programming

Tripathy, Arabinda - In: Management Science 30 (1984) 12, pp. 1473-1489

A timetabling problem is formulated as a large integer linear programming problem in 0-1 variables. A solution method based on Lagrangean relaxation coupled with subgradient optimization is presented. The solution method also incorporates a branch and bound procedure which takes advantage of...

Note--Aggregations of Subsidiary Firms for Minimal Unemployment Compensation Payments Via Integer Programming

Salkin, Harvey M.; Lin, C. H. - In: Management Science 25 (1979) 4, pp. 405-408

In Ohio, as well as several other states, annual unemployment compensation payments paid by a corporation can be minimized by solving a set partitioning problem which has all possible nonzero binary columns. The scenario, along with the model and an illustration are given. Some solution...

Maximization of Labor Productivity Through Optimal Rest-Break Schedules

Bechtold, Stephen E.; Janaro, Ralph E.; Sumners, De Witt L. - In: Management Science 30 (1984) 12, pp. 1442-1458

This paper focuses upon the maximization of labor productivity through selection of the optimal number, duration, and placement of rest breaks. It is demonstrated that resolution of the limited validity associated with previous models leads to a mixed-integer quadratic programming formulation of...

Municipal Resource Allocation: Minimizing the Cost of Fire Protection

Seward, Samuel M.; Plane, Donald R.; Hendrick, Thomas E. - In: Management Science 24 (1978) 16, pp. 1740-1748

Municipal decision-makers face the difficult task of determining the amount of funds to be allocated for fire department services. This decision affects both the insurance class of the city and the total cost of fire protection. Total fire protection cost is the sum of the tax dollars spent for...

A Multiobjective Discrete Optimization Model for Land Allocation

Gilbert, Kenneth C.; Holmes, David D.; Rosenthal, Richard E. - In: Management Science 31 (1985) 12, pp. 1509-1522

A multiobjective integer programming model is presented for allocating an area of land for development. The objectives considered in the allocation are cost, proximity to desirable and undesirable land features and the shape of the area. An interactive multiobjective optimization algorithm is...
