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...

The relative location of facilities in a functional layout has been determined under the criterion of materials handling cost minimization. Recent advances in analytical methods have provided superior solutions within this criterion hut the validity of certain underlying assumptions must be...

This paper presents a new methodology for determining suboptimum relative location patterns for physical facilities. It presents a computer program governed by an algorithm which determines how relative location patterns should be altered to obtain sequentially the most improved pattern with...

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...

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...

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...
