Improved Penalties for the Branch and Bound Algorithm
Improved penalty calculation for the branch and bound algorithm, as applied to mixed integer programming problems, are presented. For a given variable, finding the best (“up” or “down”) penalty requires solving a mixed integer program. When…
Job Shop Scheduling with Due Dates and Operation Overlap Feasibility
This paper uses a formulation of the job shop problem with due dates that allows successive operations on a job to overlap in the schedule. Setup times and multiple transports of sublots are two applications where this formulation can result in…
Optimal Design of a Multi-item, Multi-location,Multi-repair Type Repair and Supply System
The design of a system with many locations, each with many items which may fail while in use, is considered. When items fail, they require repair; the particular type of repair being governed by a probability distribution. As repairs may be…
A Perspective on Research in Computer-Based Information Systems
This paper attempts to place research on computer-based information systems in perspective. The interdisciplinary nature of the information systems field is stressed. A conceptual framework to classify and guide research on computer-based…
Sales Force Performance and the Use of a Sales Information System
The results of a study of sales force performance and the use of a sales information system are presented. A descriptive model is discussed which identifies expected predictors of sales force performance and the use of a sales information system…

The Use of an Information System and Performance: Implications for Systems Design
A descriptive model of the use of an information system and user performance is presented. Data from a study of the use of a sophisticated sales information system and sales representative performance are analyzed according to the guidelines of…
An Alternative Simplex Criterion Under Degeneracy
When degeneracies occur, the simplex multipliers can no longer be interpreted as derivatives of the optimal value of the current basic feasible solution with respect to a non-basic variable. This paper develops an alternative criterion for…
An Empirical Study of the User-Computer Interface
A general model of conflict is applied to a description of the user-computer interface. The importance of minimizing conflict between users and the computer department is stressed. A questionnaire survey in six companies was used to help define…
An Extension of the Frank and Wolfe Method of Feasible Directions
The Frank and Wolfe method of feasible directions is shown to be a case of the more general computational approach of inner linearization followed by restriction. An extension is proposed based on this observation. The extended procedure…

Comparison of Nurse Allocation Policies -- A Monte Carlo Model
Many hospitals have historically used a fixed staffing policy for allocating nursing personnel, in which the daily demand in each ward is met by nurses who are permanently assigned to the specific wards. In recent years, the concept of variable…
Consequence Evaluation in Decision Analytic Models of Medical Screening, Diagnosis, and Treatment
This paper examines the problem of assigning values, or utilities, to separate consequences in decision analytic models of medical screening, diagnosis, and treatment. Several important issues related to this problem are studied, and a number of…
A Generalized Approach To Dantzig-Wolfe Decomposition For Concave Programs
The Dantzig-Wolfe decomposition procedure for concave programs can be viewed as inner linearization followed by restriction. In this paper an approach which allows selective inner linearization of functions and utilizes a generalized pricing…

Job Shop Scheduling With Due Dates And Variable Processing Times
A multi-pass heuristic scheduling procedure developed for job shop scheduling problems with deterministic processing times is tested with processing times that are random variables. The heuristic procedure, which uses expected processing times,…
Job Shop Scheduling with Due Dates and Overtime Capability
A scheduling procedure is proposed for the static job shop problem with job due dates and a shop with overtime capability. An example is used to demonstrate the procedure and the generation of trade-off curves relating overtime and tota tardiness…
