This paper summarizes work performed in evaluating shortage costs associated with stockouts for each of a manufacturer's seven thousand catalogued line items. A modified version of a decision tree model proposed by Yu Chang is employed in a determination of estimated unit shortage costs for a...

This paper summarizes an actual study conducted for the State Planning Organization of Turkey with the objective of formulating a national R&D policy, the implementation of which will contribute to the realization of the national goals stated in the development plans of the country. The study...

The linearization technique of Glover, which seems to be the most efficient one appearing in the literature, requires the addition of n new continuous variables (unconstrained in sign) and 4n new linear constraints to equivalently represent a 0-1 "quadratic" integer problem with n variables....

This paper proposes a methodology for evaluating and selecting R&D projects in a collective decision setting, especially useful at sectorial and national levels. It consists of two major phases: Evaluation and Selection. The evaluation process repeatedly uses mathematical programming models to...

A number of manpower planning models are developed and optimized. The models are dynamic feed forward models and treat people as the only flow variable. The flow originates by considering a particular population of eligible persons and then traces them through the educational and economic...

This paper presents a structural and a mathematical framework for the analysis and/or synthesis of a large class of production systems. Service and/or goods producing enterprises are considered to be production systems. The structural framework consists of a generalized schematic involving...

This article presents a mathematical model describing the most general case in equipment investment policy. A systematic study of all other cases in the order of decreasing complexity follows. The general model reduces to their present worth all disbursements and receipts involved in the...

It is generally recognized that reinforcement, over an extended period of time of a given subject matter taught, enhances the student's mastery and subsequent retention of knowledge and/or skills. Recent major studies of curricula have concentrated on the content and method of presentation but...
