ABSTRACT
This chapter presents a collection of useful formulas and computational examples for manufacturing and production operations. Some of the formulas in this chapter contain constants that serve as adjustment factors for machine productivity measurements. These are mostly based on fitted regression analysis of large samples of production data. The facility utilization levels and equipment efficiency factors are accounted for in some of the suggested formulas. For example, if a human can produce one unit of a product per unit time, a machine can produce a certain higher number of units of the same product per unit time. Specific adjustments of the constants (up or down) in the formulas may be necessary, depending on the perceived or observed efficiency of a machine relative to the efficiency of a human worker. The formulas are general guides. Users in an actual production environment many need to customize (or localize) the formulas for their specific operating scenarios of interest. Further details can be found in Badiru (2012), Badiru and Omitaomu (2007, 2011), Badiru et al (2008), Heragu (1997), and Moffat (1987).
