Resource smoothing: A cost minimization approach

From the available literature, there seems to be no defined approach to resource smoothing exercise except those attempted by Weist (1967, Management Science, 13, B359-B377) and Burgess and Killebrew (1962, Journal of Industrial Engineering, 13, 76-83). The aim of the smoothing exercise is to achieve optimal resource usage by avoiding high peaks and deep valleys in the project resource profile. The general approach has always been to move some activities with floats in the high peak regions to be started at a later date, and as this is done, the valleys will be filled to smooth the resource profile subject of course to time constraint. If this approach is followed as it is, it would be difficult to determine optimality especially when many resources are involved. A cost minimization approach is envisaged in the present study with no limitation on the number of resource inputs. In a situation where the resources are assumed to have the same value, the cost assigned to each of them should be similar. The method follows the general concept but with a difference; cost of the activity in question is considered. The exercise is continued until all the floats are exhausted. The optimum result would then be the one with the minimum cost profile. From examples used for the evaluation, the results obtained are comparable to those of the above two researchers, and some with better results in the majority of cases.

On the Doubly Regenerative Stability of a Grinder: the Combined Effect of Wheel and Workpiece Speed

The conditional stability of a plunge cylindrical grinder is worked out in explicit terms of wheel and workpiece speed. The analysis is an extension of the theory developed in the paper “On the Doubly Regenerative Stability of a Grinder.” This paper was published in JOURNAL OF ENGINEERING FOR INDUSTRY, TRANS. ASME, Series B, Vol. 96, No. 1, Feb. 1974, pp. 275–280. An example problem is solved. The machine and cutting parameters used by Hahn in his original analysis are employed. The results are plotted as a graph of wheel versus workpiece speed with unstable areas cross-hatched. It is shown that (1) improved stability accompanies high-speed grinding; (2) below given speeds of the wheel and/or workpiece all grinding is unstable; (3) although the difference is small, the destabilizing effect of the workpiece is greater than that of the wheel; (4) grinding frequency can be used to predict the onset of chatter.

Determination of Standard Sizes to be Manufactured Using Dynamic Programming—An Extension

Abstract This article explains how the dynamic programming application presented in the August, 1968 issue of The Journal of Industrial Engineering entitled “Determination of Standard Sizes to be Manufactured Using Dynamic Programming” and authored by D. M. Jackson and D. R. Zerbe, is nonoptimal. It also considers the more realistic problem in which the number of standard sizes is not preselected, and in which the manufacturing cost of a standard size is not a constant, but interrelated with the quantity to be manufactured.

Linear Programming Techniques in Regression Analysis: The Hidden Danger

Abstract An extended debate of the alleged virtues of LP as a substitute method for regression analysis by least-squares appeared in The Journal of Industrial Engineering. The motivation for this substitution is the ability of LP to restrain unwanted negative coefficients. After recounting the histories of these two methods and the Journal controversy, this article compares their use on a simple problem. Using n-dimensional space illustrations, the conditions which produce the “unexpected negative” phenomena are then set forth. A general theorem is presented. Two classes of inter-correlation are distinguished where one is generally helpful and the other generally harmful. Within this framework, the dangerous conditions of which sign-reversals are symptomatic are discussed with the conclusion that statistical problems should be treated with statistical analysis techniques.
