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…
This paper reports on the design, implementation and use of a model for scheduling the production of nuclear isotopes. The model is formulated as a multiple-period linear programming problem with several classes of product demand…
There exists a class of decision problems for which: (1) models of input-output response functions are not available in a closed-form, functional representation; (2) informational costs associated with learning about the response…
This paper presents a method for the specification and evaluation of software modules. The proposed strategy involves the use of existing documentation and synthetic or benchmark programs to evaluate a set of key characteristics…
The problem of maintaining a balance between production output and demand growth during new product introductions is analyzed. In many cases, the introduction of a new product results in both rapid demand growth and significant…
An iterative machine procedure is described for job shop scheduling with due dates. The procedure uses a multi-pass heuristic scheduling program originally developed for static problems with deterministic processing times…
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…
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…
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…

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…
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…

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…
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…

We develop finite stage decision processes in the notation of Denardo [3] and provide conditions sufficient to prove that (i) n-stage returns exist (are unique) and are “subfinite”, (ii) optimal returns exist and are finite, (iii)…
This paper extends the author’s [8] work on decision process, developed in the notation of Denardo [5], from the finite state (nonstationary) case to the infinite stage (nonstationary) case. The paper focuses on “structured”…
A number of problems have plagued the development of computer systems, especially software projects. One method to help manage such projects is to use performance evaluation techniques for each stage of the development effort. The…
